C. Academic Profile
1. RESEARCH STATEMENTS
2005
Jul – present Health
Systems Issues in Geriatric Psychiatry.
Although I have always had a keen interest in health system issues, this did
not emerge as a research interest for me until 2005, when I became part of the
Mental Health/Long Term Care committee for the Ministry of Health and chair of
the alignment subcommittee. In 2005 I become the recipient of a large MOH
funded grant to explore the impact of newly funded psychogeriatric outreach
teams on Long Term Care.
As a result of this work, a report was compiled and submitted to the LHIN. This
document was used in subsequent reports, both local and national, and has
resulted in two publications in scientific journals. Both the reports and
publication call for greater integration in the long term care sector,
particularly with academic institutions, leading ultimately to increased
knowledge translation.
1999
Jul – present Psychosis and
Dementia.
Much of my research throughout my career to date has focused on a relatively
neglected field of Geriatric Psychiatry, namely psychosis and dementia. I have
published numerous reviews and original research reports of the clinical
correlates, neuroimaging correlates and neuropathologic correlates of these symptoms
and the implications these findings have for treatment. I have received
peer-reviewed funding to explore the functional correlates of these symptoms in
Alzheimer’s disease and the imaging and neuropathological correlates of these
symptoms from CIHR and have chaired international groups interested in the study
of these symptoms including the NPS-PIA psychosis subgroup. I have also
presented on this topic to numerous audiences, both local, national and
international, leading to increased awareness of these symptoms and their
management.
1999
Jul – present Dementia in
Specialized Populations (inner city).
A third area of focus in my research is exploring dementia in specialized
populations, such as the inner city. Given the inner city location of St.
Michael’s Hospital and the disparity in socioeconomc status among patients
seen, it has provided an ideal opportunity for examining cognitive reserve and
related topics.
This has led to peer reviewed funding in areas such as the ses correlates of
response to cognitive enhancers and a number of publications focusing on the
diagnosis of dementia in the inner city. A recent highlight includes a key
paper published in the journal CORTEX identifying that bilingual patients with
AD have significantly more brain atrophy for the same level of disease when
compared to monolingual patients. I have also presented on this topic to
numerous audiences, both local and national, leading to increased awareness of
the clinical presentation of dementia in an inner city setting and increased
comfort with it’s management.
2. TEACHING PHILOSOPHY
My approach to teaching and teaching philosophy have been influenced by
a number of factors, including my own positive learning experiences as well as
feedback from evaluations and the growth of my knowledge. My teaching has been focused primarily in the
area of geriatric psychiatry and in the imparting of that knowledge to other
learners at multiple levels including the undergraduate level, postgraduate
level and the continuing medical education level. I have also in the past few years taken on a
number of international as well as local elective students with an interest in
geriatric psychiatry and also supervised a number of undergraduate neuroscience
research students. My strengths in
teaching are primarily in the realm of imparting didactic knowledge and in
creating a culture of learning that values curiosity and openness. This is reflected in my evaluations which
show particular strength in terms of undergraduate level clinical teaching as
well as continuing medical education.
In my initial years, I believed that the function of a teacher was primarily to
impart knowledge. This perception has
changed over time. I now believe that it
is not only an obligation to impart knowledge but to aid in the process of
understanding knowledge. In other words,
to put that knowledge into some sort of context that makes it memorable. Over the course of the past few years I have
focused my energy more in the area of clinical teaching and identifying
clinically relevant teaching moments that can benefit students. One of the primary impediments to my teaching
at a clinical level has been time. Due
to competing demands on my time as I have progressed academically,
unfortunately I have been left with less time to devote to teaching. This has been both a positive and a negative
as it has forced me to teach more efficiently.
I try now to take advantage of any opportunity I have interacting with
learners to provide some meaningful knowledge that will enhance their
perception of a problem, whether that knowledge will be in a didactic form or
problem-based. I have also tried to
respond to learners with more direct and specific feedback, including both
undergraduate students as well as medical residents, something that I struggled
with in the past. I think my improved
teaching evaluations do reflect this more concerted effort.
While I get enjoyment from teaching at all levels, I have to say that my
greatest enjoyment is teaching at the continuing medical education level. I feel very privileged when given the opportunity
to enhance the knowledge base of large groups.
I very much enjoy the challenge of breaking down complex topics so they
can be easily understood by the audience.
I believe that this has been reflected in my positive continuing medial
education evaluations. This is also
particularly useful when explaining concepts to undergraduate medical
students. I also think that as a
teacher, I am very approachable and flexible in my teaching style. This has allowed students to feel very
comfortable and at ease with me and to put forth their best effort given that
they are not likely to feel threatened or intimidated by me. I have also taken great pleasure in
supervising a number of research students who have gone on to present their
work at meetings and participate in grants and publications. Ultimately, many of them have gone on to
pursue promising careers in fields such as medicine and graduate school. In addition to a teacher being an imparter of
knowledge, I also believe a teacher serves as a role model. I have tried to impart to students that I
have mentored the importance of a balanced approach to work as well as life in
general. I think these qualities,
including empathy, compassion and professionalism are something to be
emphasized in my teaching interactions.
In summary, although I have particular strengths in the area of clinical
undergraduate teaching and continuing medical education, I have continued to
persevere in other more problem-based teaching areas such as problem-based
learning and post graduate teaching. My
improved teaching evaluations demonstrate my success. My plan in the coming years is to continue to
focus on these areas in order to develop them more fully in addition to
maintaining what is good about my teaching.
3. CREATIVE PROFESSIONAL ACTIVITIES STATEMENT
In my creative professional dossier I will detail accomplishments in
the area of Creative Professional Activity since July1999 when I joined St.
Michael’s Hospital and more specifically since my last promotion in July 2005.
These activities are informed by our department’s strategic plan composed of 4
pillars, integration, development, brain and dialogue as well as the strategic
plan of St. Michael’s Hospital, quality care through knowledge, as well as my
own commitment to excellence in clinical care, teaching and research.
In 1999 I took over leadership of geriatric psychiatry services at St.
Michael’s Hospital, located in the inner city of Toronto. Since that time I have built two state of the
art clinical programs, including the Memory Disorders Clinic and the Geriatric
Mental Health Outreach Team. I have
significantly enhanced hospital funding for these programs, which have
significantly improved the quality of care for older patients living in the
area of southeast Toronto. I have
brokered strong, trusting relationships among a number of stakeholders,
including clinicians, frontline service workers, policy makers and
patients. Finally, I have used these
clinics as a platform for teaching and research, leading to increased grant
funding, publications and presentations at local, national and international
conferences. This has contributed to the
broader dissemination of my work.
In addition to my role in developing geriatric psychiatry services at St. Michael’s
Hospital, I have also served as the clinical care co-ordinator for the division
of Geriatric Psychiatry since 2003.
Through this role, I have been able to have significant impact on the
development of psychogeriatric services in Toronto and was pivotal in the
creation of the Geriatric Mental Health Outreach Network, a program that aims
to provide enhanced care for residents living in Long term Care Homes with
behavioural symptoms. I was also funded
by the MOHLTC to conduct an evaluation of this program which I have gone on to
publish and present at scientific meetings.
This study has also informed subsequent local, regional and national
initiatives in this regard such as “Behavioural Supports Ontario”. Finally, I was elected to the board of directors
of the Canadian Association of Geriatric Psychiatry in 2012. This position has allowed me to have
influence over policies and procedures at a national level.
In all of these actitivites, I have made significant contributions, locally and
nationally, through:
• Sustained innovation and
creativity in setting up programs designed to serve vulnerable inner city
elderly, enhancing collaborative care and contributing to health system
co-ordination.
• The development of physician
and allied health practices.
• Effectively influencing public
policy.
• Peer and non-peer reviewed
funding
• Peer and non-peer reviewed
publications
• Presentations at local,
national and international meetings.

The experimental intervention will be the Vielight Neuro photobiomodulation device (PBMT). The control group will receive treatment using an identically appearing sham device, on an identical treatment schedule. The device uses 5 light emitting diodes (810nm wavelength) – see appendix 2.
Diodes are placed on the skull held in position by two lateral aluminium bands, as well as intranasally to target the hippocampus, posterior cingulate cortex, medial prefrontal cortex, precuneus, inferior parietal lobe, and temporal lobe – the nodes of the Default Mode Network. The power density of each transcranial LED diode is: 100 mW/cm2 for each of the 3 LEDs on the posterior band, and 75 mW/cm2 for one LED on the anterior band.

Our group proposes a more efficient and lower radiation dose model for the measurement of cerebral amyloid levels to identify at-risk patients for Alzheimer’s Dementia (AD) following an analogous approach to thyroid imaging. Through use of our novel amyloid measurement protocol, we expect that the amyloid uptake (or the uptake normalized to thigh activity) will correlate well to standardized amyloid uptake on a conventional PET scan. Furthermore, we expect that the absolute un-normalized cerebral amyloid activity measurements obtained using our novel protocol and specialized brain PET tracer activity detector will strongly agree with the results obtained from a conventional amyloid PET scan. Finally, we expect that results obtained from our new test and a conventional PET scan will correlate strongly to the clinical presence of AD. Overall, we believe that the results of our project will allow for earlier detection, monitoring and intervention in younger at-risk patients to delay onset of AD.

Previous research, including our own data, consistently demonstrates that
patients with mild cognitive impairment (MCI) may be at increased risk of
driving impairment. Despite the wide spread prevalence of MCI and its potential
impact on driving, there are no published guidelines specifying when patients
with MCI should be considered unsafe to drive. Furthermore, there are no tools
with sufficient validity to assist healthcare professionals in assessing the
driving fitness of MCI patients. The current study aims to combine functional
magnetic resonance imaging (fMRI), driving simulation, and tablet technologies
to determine whether the brain activation patterns associated with specific
neurocognitive tests are predictive of the driving behaviours, and associated
neural networks, of patients with MCI. The results of this study will provide
direct empirical evidence regarding the utility of these neurocognitive tests
in assessing the driving fitness of MCI patients and will inform the
development and implementation of other valid and clinically useful tools.

The TDRA clinics have the potential to develop one of the largest, prospective,
real-world tertiary cohort studies as a unique demonstration project of
research-embedded in care. Through the 2000 new patients and 4000 follow-ups
seen annually among the TDRA clinics, the understanding of disease pattern and
progression through access to clinical and imaging data in this platform will
enable design of clinical trials for better prediction of the most appropriate
therapeutic courses and improved disease outcomes. The proposed platform offers
an economically efficient partnership between two public services fundamental
to the Canadian way of life – the research university and our health care
system – and provides the potential not only to improve care but also to create
the future of care by providing a platform for rapid translation from bench to
bedside. This platform can provide opportunities for integration with
provincial, national and global initiatives. As preliminary examples, TDRA has
played central roles in the OBI-funded cohort study across neurodegenerative
dementias (ONDRI) and in the newly inaugurated CIHR-funded national research
initiative, CCNA. By hosting the proposed platform in BrainCode, after an
agreed upon exclusivity period and with proper data access and review
processes, de-identified data will become available to other qualified
neuroscience researchers. Brain Canada supports linkage of BrainCODE data sets
with CCNA through the PSG, “CBRAIN: Canadian Brain Research and Informatics

Accumulating clinical and preclinical evidence indicates that excessive
neuronal excitability in the medial temporal lobe (MTL) structures may play a
causal role in progression of pathology in amnestic mild cognitive impairment
(aMCI) to Alzheimer’s Disease (AD) dementia.
We propose a phase IIa randomized placebo-controlled trial of
levetiracetam (LEV) to reduce this excitability and thus delay symptom
progression in subjects with aMCI. This is a 1 year long repurposing study
which will use a low dose of a generic, Health Canada approved drug, with a
lengthy history of safety and excellent tolerability for the treatment of

We propose to establish a representative network of Canadian LTC facilities
to enable evaluation of innovative pharmacological, non-pharmacological, and

be aimed at preventing the development of NPS, and minimising their severity,
duration and impact. We envision recruiting up to 30 LTC facilities across
Canada with representation from every region and including both urban and rural
settings and for profit and not-for-profit LTC facilities. We intend to build
research capacity in these institutions by training staff, developing common
assessment instruments, and instituting electronic data capture systems for a

This CNS drug discovery platform will be centered on existing CFI-funded
drug screening infrastructure recently installed at St.
Michael’s Hospital in Toronto, which allows robotic screens of multiwell
microplates using “humanized” or
fluorescently/luminescently labeled zebrafish embryos, carrying human
transgenic mutations or with functional gene knockout. The
platform is a state-of-the-art system that can perform fully automated screens
from fish embryo sorting and drug dosing to efficacy
readouts. The system is operated by robotic arms and customized screening
software. The Brain Canada PSG funding will greatly
improve the platform’s performance by hiring new research staff to run the
platform for the associated computer and mechanical
engineering work, drug database development and chemical informatics. It will
also be used for drug screening tool development
and obtaining new compound libraries for drug screens.

assess the driving fitness of individuals with cognitive impairment. Using our
novel functional MRI combined with our fully-immersive MR compatible driving

of patients with mild cognitive impairment (MCI) and early Alzheimer’s disease
(AD) while they are performing driving manoeuvres of increasing levels of
complexity and compare them to those of healthy age-matched controls. Identifying
the neural networks implicated in driving impairment in individuals with MCI
and AD will be an important first step to the establishment of accurate driving

Five hundred thousand Canadians have dementia, a number that will double
within a generation due to the ongoing aging demographics of the population,
with annual costs estimated to increase from $15 billion currently to over $150
billion by the year 2050. The estimated total cost to the society including the
loss of productivity by the caregivers, is predicted to be $872B. Delaying
dementia onset by 2 years would reduce this cost by $219B. Diagnosis very early
in the course of disease will be required to accomplish this goal. Brain
imaging or a spinal tap is currently required to identify people at early
stages of the disease, but such procedures are either too costly or invasive to
be used broadly for screening and early detection. Hence, we plan to test two
non-invasive measurements performed in the eyes to identify patients at early
disease stages. One of these (spectral domain optical coherence tomography)
involves assessment of changes in the nerves and blood vessels in the retina.
The other (an infrared laser quasi-elastic light scattering procedure) has been
developed to detect pathology related to a key protein called beta-amyloid
(involved in development of AD) in the lens of the eyes prior to its
accumulation in the brain. The effectiveness of these techniques will be tested
by comparing them with brain imaging (MRI) and clinical, cognitive, behaviour,
mood and functional assessments. We plan to study 60 normal elders, 65 patients
with mild cognitive impairment, 65 with AD, 65 with Lewy Body Disease and 60
with Vascular Cognitive Disorders. Selected patients will also undergo an
assessment of retinal blood vessels and positron emission tomography (PET) to
evaluate brain beta-amyloid. All patients will be recruited from the affiliated
memory, stroke and movement disorder clinics of the Toronto Dementia Research
Alliance. If these eye measurements are found effective in identifying patients
with dementia at early stages of disease, it would open new opportunities for
earlier deployment of investigative treatments, with impact on clinical care
and economic costs.

The current project aims to provide direct, empirical evidence empirical
evidence in a continuous range of age cohorts to investigate how aging impacts
the neural correlates of driving behavior. We use functional magnetic resonance
imaging (fMRI) combined with a novel driving simulator to examine in vivo brain
responses while older drivers are performing a variety of simulated driving
tasks. Our team has successfully developed an immersive, 3.0 Tesla MRI
compatible driving simulator system. This advanced set-up allows us to
successfully localize brain activations responsible for different real-life
driving behavior in the older drivers in a safe environment as compared to
young drivers. Results of the current study will establish an important
knowledge base for better selection and future development of objective and
office-based driving assessment tools, including neuropsychological tests, as
well as targeted rehabilitation strategies, which will ultimately improve the
health care system for older generations in Canada.

Delusions, rigidly-held false beliefs, occur in up to 50% of people with
Alzheimer’s disease (AD)(1), as well as in a small proportion of patients with
mild cognitive impairment (MCI, a condition associated with an increased risk
of dementia)(2)(3)(4)(5). Compared to patients with dementia without delusions
(D-), those with delusions (D+) tend to have more rapid progression of
cognitive impairment(3)(6)(1)(7)(8), lose independence in activities of daily
living more quickly(9)(10), and transfer to long-term care earlier in the
disease course(11). The presence of delusions in dementia is also associated
with aggressive behavior(12)(13)and increased caregiver stress(14)(10). In our
pilot work using data from the Alzheimer’s Disease Neuroimaging Initiative (ADNI)
database, we found that 81% of participants with MCI who developed delusions
were diagnosed with probable AD during study participation, including 8 in whom
delusions preceded the dementia diagnosis. Greater understanding of how and why
people with dementia develop delusions is crucial to efforts to prevent and
treat these symptoms. Most studies to date have examined delusions late in
moderate to severe dementia (15)(16). Most research is cross-sectional in
design, and many reports have not distinguished patients with hallucinations
from those with delusions. Delusions are more frequent than hallucinations, and
they appear to have a different underlying biological substrate(17).Little is
known about the natural history of delusions and the extent to which they are
stable over time. The current project proposes to examine factors associated
with the development and stability of delusions over time in a large database
(National Alzheimer’s Coordinating Centers, NACC) that includes initial visit
data on over 23,000 people who initially presented with normal cognition, MCI,
or dementia (various subtypes). We anticipate that the majority of participants
will have data for one or more follow-up visit.

Quality-of-life (QoL) is important in Alzheimer’s disease (AD) because no
cure exists. Measuring QoL provides a way of assessing the ‘humanistic element’
of AD treatments. Patients and caregivers currently estimate QoL in AD by
answering questionnaires. Question responses are converted into scores ranging
from 0 (worst possible QoL or death) to 1 (perfect health). However, patients
and caregivers give different QoL scores and very sick AD patients often cannot
answer QoL questionnaires. We will examine whether the general public can
provide QoL scores in place of patients and caregivers. To do this, we will
develop stories describing what happens to people who have mild, moderate, and
severe AD. Patients, caregivers, and physicians will help us develop these
stories. Afterward, we will conduct a survey that contains the stories and see
if a sample of the general public in Canada gives QoL scores that decrease as
disease severity increases.

identifying AD-D+ early in the
disease course so that appropriate treatment and caregiver support can be
given. This will help reduce
some of the excess disability associated with delusions in patients with MCI

Driving is the primary source of transportation for older adults. Loss of
driving privileges is often considered catastrophic by older adults and can
result in serious adverse consequences such as social isolation, depression and
loss of independence. Mild cognitive impairment (MCI) has been found to be
associated with diminished driving performance. Clinicians and policy makers
are challenged by the growing numbers of older drivers with MCI and the need to
maintain their mobility to allow them to retain their functional autonomy.
Currently, physicians have nothing to offer these individuals to
improve/maintain their driving performance and to potentially prolong the time
that they are able to drive safely, as well as allow them more time to prepare
for driving retirement. Executive
function and processing speed are recognized critical correlates of driving
performance and have been shown to decline in older adults and in persons with
MCI. Members of our research team have shown that group executive function
training such as Goal Management Training (GMT) results in benefits for healthy
older adults, including improved simulated daily activities. A previous study
has
shown that computerized processing speed training (PST) may reduce crash rates
in healthy older adults. The ultimate
purpose of our research is to develop interventions to help maintain older
adults’ mobility in order to assist their ‘aging at home’. To address this
purpose, the planned study will assess the effectiveness of an intervention
(GMT + PST) designed to address both executive function and processing speed
changes that contribute to poor driving performance in people with diagnosed
MCI.

Our study will provide critical information regarding the feasibility and applicability of screening for NMDAR encephalitis among patients presenting with FEP, something never done before. This knowledge could be used to inform screening guidelines for patients presenting with FEP. As well, our study will ensure that patients in our sample who have this disorder and present with psychiatric symptoms are screened for this condition and, if identified, will be offered appropriate treatment, thus leading to better treatment outcomes, improved quality of life and cost savings. Moreover, by better characterizing the imaging and clinical correlates of this population we hope to better understand the underlying neurologic mechanisms leading to the development of psychotic symptoms in related disorders, potentially leading to the development of novel treatment approaches

Grey matter changes associated with the development of delusions in Alzheimer’s disease. American Journal of Geriatric Psychiatry. (2018) https://doi.org/10.1016/j.jagp.2018.09.016. Senior author.
This study was funded by CIHR, utilizes the NACC data set and compares rates of grey matter atrophy in AD patients pre and post onset of delusions, both cross-sectionally and longitudinally. The results suggest that delusions in patients with AD may be associated with accelerated grey matter atrophy in the temporal lobes and that the pre-delusional phase may be characterized by an increase in brain volume in these areas, thus raising the possibility of neuroplastic mechanisms and possible translation to other psychiatric disorders associated with psychosis.

This study was funded by CIHR, utilized data from the NACC data set and compared the effect of psychosis on rates of clinical misdiagnosis. The key finding of the study was that psychosis was associated with a low false positive and high false negative rate of misdiagnosis, likely driven by the tendency to over-diagnose patients exhibiting psychosis with Dementia with Lewy Bodies. It was extensively cited in the media, including Reuters.

Journal of Alzheimer’s Disease. Journal of Alzheimer’s Disease. 2016 Jan 6(50):283-295. Principal Author.
This study was funded by CIHR, utilized data from the NACC data set and explored the relationship of psychotic symptoms to post-mortem biomarkers including Lewy bodies, subcortical ischemic vasculopathy and AD biomarkers. It demonstrated the previously cited association with AD biomarkers but only in patients clinically diagnosed with AD. When the sample was limited to patients with a confirmed neuropathological diagnosis the only notable association was with Lewy bodies and subcortical ischemic vasculopathy, thus suggesting that these pathologies may mediate psychotic symptoms and that the previous cited association with AD biomarkers may have been driven by misdiagnosis. This paper was extensively cited by the media.

This study was funded by CIHR and uses voxel based morphometry to compare AD patients with delsuions pre and post delusion onset. It is the first longitudinal study of it’s kind to address this question. The study found that onset of delusions was aossciated with focal atrophy in the left posterior hemisphere, including the cerebellum and areas that correspond to the default miode network. Thus, it suggests that delusions in patients with AD may be associated with morphological changes in the posterior left hemisphere, including the cerebellum and default mode network, providing a potential target for therapeutic intervention. - Schweizer T, Ware J, Fischer C, Craik F, Bialystok E.

This study was conducted on patients recruited from the St. Michael’s Hospital Memory Disorders clinic. AD patients who were bilingual and matched for other variables were compared in terms of grey matter volume in the medial temporal lobe, an area associated with AD. The study showed that patients who were bilingual had significantly lower brain volume in this brain region, and thus they were able to compensate for damage secondary to AD. The study provided the first physical evidence for cognitive reserve mediated by bilingualism, received extensive media coverage, and has been cited in the scientific literature over 150 times.

Invited Lectures and Presentations
2019 Mar 2nd Presenter. Symposium. Prevalence of Neuropsychiatric Symptoms Across the Cognitive Spectrum and their Impact on Future Cognitive Decline. American Association of Geriatric Psychiatry Annual Meeting, Atlanta, Georgia.
We argue that NPS across the spectrum of AD disease should not be conceptualized a simply co-existing alongside cognitive impairment or attributable to mood or behavioural disorders, but rather, are core features of cognitive neurodegenerative conditions that may serve as prognostic indicators of outcome. This symposium will review neurobehavioural or neuropsychiatric (NPS) symptoms across the cognitive spectrum; namely in cognitively unimpaired (CU) or subjective cognitive decline (SCD); mild cognitive impairment (MCI); and Alzheimer’s disease (AD) and their association with AD biomarkers and contribution to future cognitive decline or AD disease progression.
2018 Jul 25 Chair Featured Research Symposium Psychosis and Neurodegeneration: New Frontiers. Alzheimer Association International Congress, Chicago, Illinois
Faculty: Dr. Zahinoor Ismail, Dr. David Munoz, Dr. Jeffrey Cummings
Alzheimer’s disease (AD) and related neurodegenerative disorders are associated with the development of psychotic symptoms in approximately one third to one half of patients. Moreover, the presence of these symptoms is associated with adverse outcomes including increased risk of mortality, more rapid disease progression and increased neurobehavioural symptoms. In spite of the prevalence of these symptoms and their association with adverse outcomes, effective treatments are limited and the etiopathogenesis remains unclear. This symposium will present new unpublished data that shed light on the underlying mechanisms and treatment of these symptoms. The first talk will leverage data from the National Alzheimer’s Disease Co-ordinating Centre (NACC) database to demonstrate that delusions in presymptomatic AD patients are associated with preserved brain volume of regions corresponding to the nodes of the Default Mode Network (DMN) relative to asymptomatic AD patients. The second talk will provide further support for the link between delusions in AD and the DMN by demonstrating reduced cohesion of the left inferior parietal lobe within the DMN in delusional AD subjects relative to subjects without delusions using fMRI. The third talk will again leverage data from the NACC database to show that psychotic symptoms are associated with increased amyloid burden in patients who are cognitively asymptomatic, suggesting psychosis may be a manifestation of amyloid burden in patients without cognitive decline. Finally, the fourth talk will detail the design and rationale of a clinical trial assessing the role of the promising pharmacologic agent, pimavanserin, in the treatment of dementia-related psychosis.
2018 Mar 17 Presenter. Understanding the Link between Neuropsychiatric symptoms and cognitive decline: Insights from neuroimaging. American Association of Geriatric Psychiatry Annual meeting, Honolulu, Hawaii
Chair: Linda Mah, MD, MHS
Faculty: Ariel Graff-Guerrero, MD, MSc, PhD, Corinne Fischer, MD,
Krista L. Lanctôt, PhD
The purpose of this symposium is to provide an overview of neuroimaging findings from various modalities (MRI, FDG-PET, PET amyloid) that are reportedly associated with specific neuropsychiatric symptoms in individuals with mild cognitive impairment (MCI): depression, delusions, and apathy.
By discussing a range of neuropsychiatric symptoms, we propose to identify common neural mechanisms underlying the association between neuropsychiatric symptoms and risk of Alzheimer’s disease. We will conclude by describing theoretical models based on neuroimaging evidence to account
for the link between neuropsychiatric symptoms and cognitive decline.
2016 Mar 17 Chair. Psychosis and dementia: when two worlds collide. AAGP. Wahsington, District of Columbia, United States. Presenter(s): Dr. Corinne Fischer, Dr. Colleen Millikin, Dr. David Munoz, Dr. Robert Sweet. This symposium will review the latest advances in the field of psychosis and dementia, with a focus on epidemiology, clinical features, neuroimaging and neuropathological correlates. We will explore how advances in our understanding of psychosis in dementia has informed our understanding both of neurodegenerative diseases and psychotic disorders. We will also look at the trajectory of psychotic symptoms from the phase of mild cognitive impairment to advanced dementia.
2015 May 17 Invited Speaker. An update on neurocognitive disorders for the general psychiatrist: Dementia presenting with psychiatric symptoms. APA. Toronto, Ontario, Canada. Presenter(s): Andrea Iaboni, Damien Gallagher, Corinne E Fischer, David Gold. There are many different subtypes of dementia that can present with psychiatric symptoms, although the overlap is much more marked with some disorders in comparison to others. In some instances the overlap may lead to a delay in diagnosis and the application of inappropriate treatments, thus having important implications for patient management. Two relatively common dementia subtypes that may frequently present with a prominent psychiatric presentation are frontal-temporal dementia (FTD) and dementia with lewy bodies (DLB). Patients with FTD typically undergo a marked change in personality in the early stages of the disease, resulting in extreme apathy or conversely impulsivity, disinhibition and socially inappropriate behavior. It may be hard to distinguish these symptoms from other psychiatric disorders such as major depression or bipolar disorder, where you may see similar changes in personality. Important distinguishing features include family history, temporal history (insidious onset) and the co-existence of language impairment. Similarly, patients who have DLB may often present with prominent psychotic symptoms, including delusions and visual hallucinations, early on in the course of the disease. Distinguishing features that should lead to an increased index of suspicion include the presence of a movement disorder (parkinsonism) and fluctuating cognitive symptoms. Patients with more conventional dementia diagnoses, including Alzheimer’s Disease (AD) and Vascular Dementia (VD), may occasionally present with psychiatric symptoms at initial presentation, although this is more rare.

Presented Abstracts
2017 Jun 26 Presenter. Neural Correlates of handwriting. Organization for Human Brain Mapping. Vancouver, June 25-29 2017. Mahta Karimpoor1, Nathan Churchill2, Fred Tam3, Corinne Fischer2, Tom Schweizer2, Simon Graham1. Our results are consistent with previous lesion studies; involving the SPL and MiFG, and the ventral pre-motor cortex for guiding hand actions (Katanoda 2001; Segal, 2012). Brain activity contrasting paragraph vs. phone number tasks showed language processing areas consistent with differential engagement for complex sentence processing vs. number processing. Involvement of left sensorimotor regions and lentiform nucleus suggest more sensorimotor demands during performing writing a paragraph in comparison to phone numbers, consistent with the behavioral data. The
present results are preliminary, but are sufficiently strong to consider including handwriting as part
of task batteries in future fMRI studies involving AD patients.
2017 Jun 26. Presenter. Effects of visual feedback of hand on motion and physiological noise during fMRI of handwriting. Organization for Human Brain Mapping. Vancouver, June 25-29 2017. Mahta Karimpoor1, Nathan Churchill2, Fred Tam3, Corinne Fischer2, Tom Schweizer2, Simon Graham1. Despite performing complex motor responses during writing, head motion effects were generally low during fMRI of both tablet conditions. Subjects who performed without VFHP showed more head displacement in the pitch direction. In summary, VFHP may not consistently reduce head motion but alters motion characteristics and influences the optimal set of pre-processing pipeline parameters.
2017 Apr 24 Presenter. Neuropathological Basis of the Effect of Apolipoprotein E Genotype on Psychosis in Alzheimer’s Disease. American Academy of Neurology. Boston, Massachusetts, USA. We identified 1509 subjects with severe AD. In this group, presence of APOE4 was associated with the development of psychotic symptoms, both delusions and hallucinations, in a gene dose-related manner, reaching significance for two alleles. This effect is only observed in subjects with comorbid Lewy bodies. Furthermore, the association is gender-specific, being much more pronounced and only reaching significance in females.
2016 Apr 17 Presenter. Cognitive and Functional Differences Between Delusions and Hallucinations in Alzheimer’s Disease. American Aacdemy of Neurology. Vancouver, British Columbia, Canada. Presenter(s): Qian W, Fischer CE, Schweizer TA, Munoz DG. This study looked at clinical differences between AD patients with delusions versus hallucinations in terms of their level of cognitive impairment, functional status, etc. Hallucinations were found to be associated with much worse outcomes.
2016 Mar 19 Presenter. Vascular risk factors and Subcortical Arteriosclerotic Leukoencephalopathy. American Association of Geriatric Psychiatry. Washington, District of Columbia, United States. Presenter(s): Fischer CE, Qian W*, Schweizer TA, Millikin CP, Ismail Z, Smith EE, Lix LM, Shelton P, Munoz DG. This study looked at neuropathological differences between AD patients with and without psychosis. Strong associations with AD pathology was found only for the clinical subgroup. Both subgroups showed a strong association with cerebrovascular risk factors and vascular pathology.
2016 Mar 19 Presenter. Delusions in Alzheimer’s disease are associated with prefrontal and cerebellar atrophy. American Association of Geriatric Psychiatry. AAGP. Washington, District of Columbia, United States. Presenter(s): Qian W, Fischer CE, Millikin CP, Ismail Z, Smith EE, Lix LM, Munoz DG, Schweizer TA. Functional and structural imaging studies largely suggest right frontal atrophy, but the neuroimaging correlates behind delusions remain inconclusive, as regions from virtually all the lobes have been implicated. Our previous cross-sectional study using data from 58 patients in the Alzheimer’s Disease Neuroimaging Initiative (ADNI) database found right fronto-temporal grey matter atrophy in the delusional subset (n=29) compared to non-delusional AD controls (n=29). The current study aimed to continue this investigation by identifying regions of gray matter atrophy in association with delusions in a larger sample of AD patients.
2016 Mar 19 Presenter. Atrophy in the Default Mode Network following the development of delusions in patients with Alzheimer’s disease. AAGP. Washington, District of Columbia, United States. Presenter(s): Qian W, Schweizer TA, Millikin CP, Ismail Z, Smith EE, Lix LM, Munoz DG, Fischer CE. The Default Mode Network (DMN), a resting state network encompassing the ventral and dorsal medial prefrontal cortex (mPFC), posterior cingulate, inferior parietal lobule, medial temporal cortex, hippocampal formation, and the precuneus, has shown abnormal connectivity in normal aging as well as in mental disorders including AD. Disrupted connectivity within the DMN may not be simply a function of disease progression, but may also play a role in the expression of delusions. The current study aimed to identify regions of gray matter atrophy following the development of delusions in patients with AD. We hypothesized that regions of the DMN would show atrophy.
2015 Jul 23 Presenter. “A Systematic Review and Meta-Analysis for the Prevalence of Depression in Mild Cognitive Impairment”. Alzheimer Association International Conference. Wahsington, District of Columbia, United States. Presenter(s): Ismail Z, Elbayoumi H, Smith EE, Fischer C, Schweizer T, Millikin C, Hogan D, Patten S, Fiest K. This was a systematic review of the prevalence of depression in mild cognitive impairment using a meta-analytic approach.

T. Schweizer. This study on amateur piano players suggests that the artistic
and other cognitive abilities are differentially impacted by AD .
Exposure to music training and performance at an amateur level can preserve
memory involved in musical expression, and these
maybe more resistant to the effect of the disease.
2014 Mar 15 Presenter. Factors Associated with Development and Stability of Delusions in Probable Alzheimer’s Disease. AAGP. Orlando, Florida, United States. Presenter(s): Millikin C, Stoesz BM, Fischer CE, Ismail Z, Schweizer TA. We compared factors associated with delusion development between 318 patients who developed delusions after baseline (D+) and 1,394 patients who never developed delusions (D-).
2014 Mar 15 Presenter. Factors associated with the development and stability of delusions in probable Alzheimer’s disease. AAGP. Miami, Florida, United States. Presenter(s): Millikin, C., Stoesz, B., Ismail, Z., Fischer, C., & Schweizer, T. The objectiveof the present study was to examine factors associated with delusion development and stability. Specifically, we hypothesized that: (1) development of delusions would be associated with earlier age at onset of cognitive decline, non-Caucasian ethnicity, and increased depressive symptoms; (2) stability of delusions over time would be associated with more severe cognitive impairment; and (3) fluctuating delusions may be related to cerebrovascular risk factors.

Presenter(s): Winnie Qian, Tom Schweizer, Corinne Fischer, David Munoz. Building on our previous finding, we aimed to investigate the functional resting-state differences between AD patients with and without delusions, as well as in a subset of patients with schizophrenia, a disorder characterized by psychosis. We hypothesized that delusions, in both the AD and schizophrenia groups, are associated with decreased DMN activation compared to non-delusional group.

Determining the Impact of Psychosis on Rates of False Positive and False Negative Diagnosis in Alzheimer’s Disease, American Association of Geriatric Psychiatry Annual Meeting, Dallas, Texas. Presenter(s): Winnie Qian, Tom Schweizer, Corinne Fischer, David Munoz. In the current study we examined how rates of clinical misdiagnosis in AD is affected by the presence of psychosis, divided into delusions and hallucinations. We hypothesized that patients with psychosis will have a higher rate of misdiagnosis than patients without psychosis, given the symptom overlap with other dementias.

of Alzheimer’s disease: Inconsistencies between clinical diagnosis and
neuropathological confirmation. Alzhiemer Association International Congress.
Toronto, Ontario, Canada. Presenter(s): Winnie Qian, Tom A. Schweizer, David G.
Munoz, Corinne E. Fischer. Despite consensus on clinical diagnostic criteria,
some patients with Alzheimer’s disease(AD) may be misdiagnosed as other forms
of dementia, and conversely, other dementias may be misdiagnosed as AD.
Misdiagnosis is a roadblock in clinical management because different dementia types
require different treatment approaches. Moreover, clinical misdiagnosis impedes
the ability to find new treatments in clinical trials because inclusion of
incorrectly diagnosed patient groups can dilute or obscure important effects.
The current study aimed to investigate inconsistencies between clinical and
neuropathological diagnoses in AD.

Munoz. Expression of Alzheimer’s disease (AD) is modulated by vascular risk
factors (vrf). Studies have shown that vrf affect cognitive function during the
early stages of AD. In addition, vascular pathology, thought to be caused by
vrf, is also associated with cognitive decline. The aim of our study is to
investigate the relationship between hypertension, cognitive function and
psychosis in patients with severe AD, and whether the mechanism is mediated
through vascular pathology.

Investigating driving errors and the brain activation patterns of patients with
mild cognitive impairment during routine and complex driving conditions. AAIC.
Toronto, Ontario, Canada. Presenter(s): Hird MA, Vesely KA, Churchill NW,
Fischer CE, Naglie G, Graham SJ, Schweizer TA. Mild cognitive impairment (MCI)
can affect multiple cognitive abilities that are essential for driving,
including attention, memory, executive functioning, and visuospatial ability.
Safe driving requires the coordination of all of these domains and corresponding
brain regions. However, the areas and degree of driving impairment
characteristic of individuals with MCI remain unknown. As a result, there are
no valid tools to help healthcare professionals assess the driving fitness of
patients with MCI. This is the first study to combine driving simulation and
functional magnetic resonance imaging (fMRI) to isolate the driving errors and
corresponding brain activation patterns of individuals with MCI while
performing driving tasks of increasing complexity.

Neurology Assessment-Revised (BNA-R) is an in-depth cognitive tool that is
intermediate between short screening tests and lengthy neuropsychological
assessments. It provides a relatively quick and reliable assessment of seven
cognitive domains: orientation,
immediate verbal recall, delayed verbal and visual recall, delayed verbal and
visual recognition, visuospatial function, working memory/attention/executive
control, and language. Our objective was to validate the BNA-R for diagnosis of
aMCI.

Alzheimer’s disease are associated with prefrontal and cerebellar atrophy.
American Association of Geriatric Psychiatry. Washington, District of Columbia,
United States. Presenter(s): Qian W, Fischer CE, Millikin CP, Ismail Z, Smith
EE, Lix LM, Munoz DG, Schweizer TA. Functional and structural imaging studies
largely suggest right frontal atrophy, but the neuroimaging correlates behind
delusions remain inconclusive, as regions from virtually all the lobes have
been implicated. Our previous
cross-sectional study using data from 58 patients in the Alzheimer’s Disease
Neuroimaging Initiative (ADNI) database found right fronto-temporal grey matter
atrophy in the delusional subset (n=29) compared to non-delusional AD controls
(n=29). The current study aimed to continue this investigation by identifying
regions of gray matter atrophy in association with delusions in a larger sample
of AD patients.

The Default Mode Network (DMN), a resting state network encompassing the
ventral and dorsal medial prefrontal cortex (mPFC), posterior cingulate,
inferior parietal lobule, medial temporal cortex, hippocampal formation, and
the precuneus, has shown abnormal connectivity in normal aging as well as in
mental disorders including AD. Disrupted
connectivity within the DMN may not be simply a function of disease
progression, but may also play a role in the expression of delusions. The
current study aimed to identify regions of gray matter atrophy following the
development of delusions in patients with AD. We hypothesized that regions of
the DMN would show atrophy.

PhD; Paul Shelton10, MD; David G. Munoz1,11,12, MD. We assessed the
relationship between psychosis and various clinical variables, neuropathologic
correlates, and vascular risk factors in patients with AD. All data was
obtained from the National Alzheimer’s Coordinating Center (NACC) database. Our
sample consisted of 1) 890 clinically diagnosed AD (cAD) patients with
neuropathology data and 2) 728 neuropathologically confirmed AD (npAD) patients
based on the CERAD “definite” AD with any clinical diagnosis. The two groups overlapped,
but each was reviewed separately. The presence of delusions and hallucinations
were identified by the delusional and hallucinatory subscores of the NPI-Q,
respectively.

Development of Psychosis a Risk Factor for Attrition in Longitudinal Studies of
Dementia? Canadian Conference on Dementia. Toronto, Ontario, Canada.
Presenter(s): Colleen Millikin, Zahinoor Ismail, Corinne Fischer.
Attrition/dropout is a challenging issue for longitudinal studies of dementia.
To date, several risk factors for attrition have been identified among
participants in longitudinal dementia studies, including baseline cognitive
status, white matter lesion volume, depression, nonspouse caregiver, and
caregiver burden. Development of psychotic symptoms (delusions and/or
hallucinations) is associated with many negative outcomes for patients with
dementia, such as more rapid cognitive and functional decline, increased
caregiver stress, and earlier institutionalization. The present study sought to
evaluate whether participants with Alzheimer’s disease (AD) at baseline who
develop psychosis have fewer study visits and less neuroimaging data compared
to those who do not develop psychotic symptoms.

(perindopril) vs. a sartan (telmisartan) in reducing progression of brain
atrophy (indexed by ventricular volume expansion on 3T MRI at 12 months), in
hypertensive AD patients. Both drugs demonstrate equal cardiovascular
protection and blood pressure control and are thought to be best in their class
for CNS effects. 2) To compare treatment responsiveness of other cognitive
(e.g. ADAS-Cog), neurobehavioural (e.g. NPI), functional and caregiver burden
measures and multi-modal MRI measures.

Investigating risky driving and turning errors in patients with amnestic and
multiple-domain mild cognitive impairment. Canadian Conference on Dementia.
Toronto, Ontario, Canada. Presenter(s): Hird MA, Vesely KA, Fischer CE, Naglie
G, & Schweizer TA. Given the heterogeneous presentation of MCI, this study
aimed to investigate the driving performance of patients with amnestic MCI
(aMCI) and multiple-domain MCI (mdMCI). It was hypothesized that MCI patients
would exhibit increased risky driving errors (i.e. collisions, centreline
crossings, road edge excursions) compared to healthy controls and that patients
with mdMCI would exhibit greater driving impairment.

MD. We assessed the relationship between psychosis and various clinical
variables, neuropathologic correlates, and vascular risk factors in patients
with AD. All data was obtained from the National Alzheimer’s Coordinating
Center (NACC) database. Our sample consisted of 1) 890 clinically diagnosed AD
(cAD) patients with neuropathology data and 2) 728 neuropathologically
confirmed AD (npAD) patients based on the CERAD “definite” AD with any clinical
diagnosis. The two groups overlapped, but each was reviewed separately. The
presence of delusions and hallucinations were identified by the delusional and
hallucinatory subscores of the NPI-Q, respectively.

Oct 2 Presenter. Delusions in
Alzheimer’s disease are associated with prefrontal and cerebellar atrophy.
Canadian Conference on Dementia. Ottawa, Ontario, Canada. Presenter(s): Corinne

Millikin7, PhD; Zahinoor Ismail8, MD; Eric E. Smith8, MD MPH; Lisa M. Lix9,
PhD; Paul Shelton10, MD; David G. Munoz1,11,12, MD. Functional and structural
imaging studies largely suggest right frontal atrophy, but the neuroimaging
correlates behind delusions remain inconclusive, as regions from virtually all
the lobes have been implicated. Our
previous cross-sectional study using data from 58 patients in the Alzheimer’s
Disease Neuroimaging Initiative (ADNI) database found right fronto-temporal
grey matter atrophy in the delusional subset (n=29) compared to non-delusional
AD controls (n=29). The current study aimed to continue this investigation by
identifying regions of gray matter atrophy in association with delusions in a
larger sample of AD patients.

Smith8, MD MPH; Lisa M. Lix9, PhD; Paul Shelton10, MD; David G. Munoz1,11,12,
MD. The Default Mode Network (DMN), a resting state network encompassing the
ventral and dorsal medial prefrontal cortex (mPFC), posterior cingulate,
inferior parietal lobule, medial temporal cortex, hippocampal formation, and
the precuneus, has shown abnormal connectivity in normal aging as well as in
mental disorders including AD. Disrupted
connectivity within the DMN may not be simply a function of disease
progression, but may also play a role in the expression of delusions. The
current study aimed to identify regions of gray matter atrophy following the
development of delusions in patients with AD. We hypothesized that regions of the
DMN would show atrophy.

the brain activation patterns of patients with MCI during routine and complex
driving conditions. Canadian Conference on Dementia. Ottawa, Ontario, Canada.
Presenter(s): Hird MA, Vesely KA, Churchill NW, Fischer CE, Graham SJ,
Schweizer TA. The current study combined driving simulation and functional
magnetic resonance imaging (fMRI) to identify the brain activation patterns of
individuals with MCI while performing driving tasks that ranged in complexity,
including both routine (e.g., right and left turns) and more cognitively
demanding (e.g. left turns with traffic) driving conditions. It was
hypothesized that patients with MCI would show a significant deviation in brain
activation compared to healthy controls during various driving conditions and,
specifically, increased activation in frontal regions involved in executive
functioning.

We conducted a longitudinal voxel-based morphometry (VBM) analysis on a well-defined cohort of ADNI participants with MCI, who developed delusions over the course of participation. We hypothesized that enhanced atrophy in the right frontal areas of the brain would attenuate the monitoring/inhibitory function of these areas, thus contributing to delusional onset.
G. Teaching and Design
I think my dossier reflects my commitment to teaching a diverse group
of learners including elective students, undergraduate medical students,
residents as well as other allied health professionals. My contributions to teaching are very much
linked to my role at St. Michael’s Hospital as being the sole provider of
education in the field of Geriatric Psychiatry.
My teaching has primarily been in the realm of geriatric psychiatry, my
chosen field, and has been in a number of clinical domains including
Consultation Liaison Psychiatry, Outpatient/Memory Disorder Clinic Psychiatry
and Long-Term Care Psychiatry.
When I first began teaching during the earlier part of my career at St.
Michael’s Hospital, most of my teaching was focused in the area of Consultation
Liaison Psychiatry as well as occasional outpatient assessment. As a result, the majority of learners were
medical students or residents doing their core rotations. In later years, I focused my attention more
on cognitive assessment and the development of the St. Michael’s Hospital
Memory Disorders Clinic. This shifted
the focus of my teaching slightly, allowing me to provide a broader experience
for learners and also attracting more specialized learners, including research
assistants and elective students with an interest in neuroscience. Finally, more recently my focus has shifted
again to the development of a Long-Term Care Outreach team. As a result, my teaching has shifted again,
to the assessment of older patients with cognitive disorders and behavioural
syndromes. This has enriched the
learning experience for students I have taken on and also provided an important
opportunity to provide education to front line staff, facilitating knowledge
translation.
In terms of my role in continuing medical education, this has also shifted
through the years. In the early part of
my career, the focus was on more general aspects of Geriatric Psychiatry. In more recent years the focus has shifted to
the management of patients with dementia in keeping with the shift in my
clinical focus. Finally, I have mentored
a number of research students as well as undergraduate medical students who
have gone on to have promising careers in fields linked to geriatric
psychiatry. I think my teaching dossier
and my evaluations reflect sustained teaching effectiveness.
1. Innovations and Development in Teaching and Education
2013 Symposium on
Psychotic Symptoms in Dementia Presented at the 2013 AAGP, Continuing
Education, Faculty of Medicine, Dept of Psychiatry, Geriatric Psychiatry
In 2013 I assembled a group of experts in the field of geriatric psychiatry
to provide the latest information on psychotic symptoms in Alzheimer’s disease,
including clinical presentation, neurobiological findings and management. The symposium was entitled “Fitting a square
peg into a round hole: understanding
psychotic symptoms in Alzhiemer’s disease” and featured renowned figures in the
field including Dr. Rob Sweet as well as prominent Canadians such as Zahinoor
Ismail. The symposium took place in Los
Angeles at the American Association of Geriatric Psychiatry and was very well
received.
2012 Symposium on
Psychotic Symptoms in Dementia Presented at the 2012 CAGP, Continuing
Education, Faculty of Medicine, Dept of Psychiatry, Geriatric Psychiatry
In 2012 I assembled a group of experts to provide an update on a very
important yet often neglected topic in geriatric psychiatry, psychotic symptoms in Alzheimer’s
disease. This symposium, entitled
“Psychotic symptoms in Alzheimer’s disease”, featured international figures in
geriatric psychiatry including Dr. Benoit Mulsant as well as national figures
such as Dr. Zahinoor Ismail. The
symposium provided the latest information on clinical findings, neuroimaging
correlates and treatment. It drew a
record audience and was very well received.
2012 Keynote

In November of 2012 I participated in a national round table discussion
focusing on issues associated with aging and dementia. The round table was sponsored by We Care, the
largest home care organization in the country, and featured members of the
public, various media and advocacy groups.
The event was well attended and very positively received.
2012 Annual
Scientific Meeting Advisory Board CAGP 2012, Faculty Development, Faculty of
Medicine, Dept of Psychiatry, Geriatric Psychiatry
In 2012 I become involved with the CAGP and joined the advisory board for
the 2012 annual scientific meeting. My
role on the committee was to review and evaluate scientific abstracts, chair
sessions and review promotional material.
The conference was held jointly with the Canadian Coalition of Seniors
Mental Health and was a resounding success.
2008 Toronto
Geriatric Mental Health Conference:
Behavioural and Psychological Systems of Dementia and Late-Life
Depression; Translating Knowledge into Practice. 2008 89 Chestnut Street, Conference Centre,
Toronto, ON, Faculty Development, Faculty of Medicine, Dept of Psychiatry,
Geriatric Psychiatry
In 2008, I co-chaired an important conference entitled Toronto Geriatric
Mental Health Conference: Behavioural
and Psychological Systems of Dementia and Late-Life Depression; Translating
Knowledge into Practice. This was done
in collaboration with the Division of Geriatric Psychiatry and the Centre for
Addiction and Mental Health. The
Division of Geriatric Psychiatry at the University of Toronto hosts an annual
conference as does the St. Michael’s Hospital Mental Health Service. This conference was an attempt to bring both
conferences together. I co-chaired the
conference along with Dr. Zahinnor Ismail who at the time was based at the
Centre for Addiction and Mental Health.
On this occasion, I had the opportunity to help develop a conference
focusing very much on issues relevant to long-term care including behavioural
syndromes in dementia as well as late-life depression. The conference was held on October 24,
2008. It featured a number of workshops
as well as several keynote presentations by internationally renowned
specialists including Dr. Eric Tangelos, who spoke on non-pharmacological
approaches to dementia care, Dr. Nathan Herrmann, who spoke on challenges in
pharmacological management of neuropsychiatric disturbances in dementia and Dr.
Benoit Mulsant who spoke on antidepressant use in older adults. There was also a panel discussion involving
best practices in service delivery in long-term care followed by several
workshops that were run by several local specialists.
The planning for this conference started approximately one year prior to the
actual event. It involved lining up
keynote and other speakers, establishing core content and identifying
appropriate workshop topics. The
conference was a great success, registering approximately 218 registrants and
receiving a total of 168 evaluation forms.
Overall, the feedback indicated the conference was successful in
achieving its objectives. Keynote and
panel presentations in the morning as well as six workshops in the afternoon
were well received with positive feedback indicated for all venues. Sixty-seven percent of respondents rated the
conference as excellent. Seventy-nine
percent rated the conference organization and registration as excellent and 63
percent said it satisfied their objectives.
Comments included:
• ‘Excellent speakers. Dr. Tangelos was outstanding.’
• ‘Very interesting, clinically
relevant.’
• ‘Good speakers in general but long
day and some speakers could have managed time better.’
• ‘Great topic – very relevant.’
• ‘‘Excellent.’
• ‘Very smooth and well organized. Better than most.’.

I. Creative Professional Activities
1. Professional Innovation and Creative Excellence
2012
Jul 1 – 2013 Jun 30 Founding Director
of the St. Michael’s Hospital Memory Disorders Clinic July 2001—present.
One of my primary focuses over the course of the past ten years has been the
development of a specialized Memory Disorders Clinic to serve the inner-city
population of metropolitan Toronto. This
was in response to the realization that many of the patients I saw early in my
career had undiagnosed cognitive impairment and had not received any formal
evaluation. Thus, they were often left
undiagnosed and untreated. With evolving
treatments for Alzheimer’s disease and the realization that these treatments
were most effective when administered early, I felt this situation was
untenable. While Memory Disorders Clinic
did exist in such specialized centres as Baycrest Hospital and Sunnybrook
Health Sciences Centre there had been no such clinics based at St. Michael’s
Hospital, where the prevalence of dementia is arguably amongst the
highest. I was able to leverage support
for this clinical from the hospital leadership and also benefitted from the
acquisition of donor funds.
I consulted with the directors of the memory disorders clinics across the city
as well as stakeholders including family doctors and specialists. I met with experts in related disciplines
such as neuropsychology, geriatric medicine and neurology. Through meetings with various stakeholders,
allied health and related disciplines, the clinic was established in 2001 and
runs to this date. This clinic has
served as an important platform both for research and education, in addition to
providing patients with state of the art medical care. At a local level, patients have had access to
new and innovative treatments for Alzheimer’s disease and related dementias. At a national level, we have been able to conduct
important research that has led to scientific breakthroughs in areas such as
cognitive reserve and neuropsychiatric symptoms in dementia. We have also been successful in securing both
peer and non-peer reviewed funding from local and national agencies and have
contributed significantly to the literature through publications in scientific
journals as well as national and international scientific meetings.
• Creation of an innovative memory
disorders clinic focused on vulnerable inner city elderly.
• 200 new assessments and 400
reassessments per year
• Improved access to diagnostic
services for patients living in the inner city of Toronto with cognitive
disorders.

studies.
• Over a million dollars in peer and
non-peer reviewed research funding
• Increased media attention at a local,
national and international level
• Membership in the Toronto Dementia
Research Alliance
• Training site for learners (medical
students, residents, fellows) in conducting cognitive assessments.
2012
Jul 1 – 2013 Jun 30 Founding Director
of the St. Michael’s Hospital Geriatric Mental Health Outreach Team.
When I first came to St. Michael’s Hospital and after my first few years I
became keenly aware of the need to provide more formalized consultation to Long
Term Care Homes (LTCH’s) in the area, most of which did not have any regular
access to a psychiatrist. As a result of trends in society and the aging
population, LTCH’s were having to cope with patients who had significantly
greater behavioural issues with very limited resources. In addition, the acute
care sector of most hospitals had little to offer such patients and would often
direct them back to their facilities after brief stays in emergency departments
with little change. Furthermore, the area of south east Toronto is particularly
challenging given that patients have very limited means and high rates of
psychiatric co-morbidity. This overall climate of frustration led to the
dedication of federal health accord funds in 2005 to the development and
augmentation of specialized psychogeriatric outreach teams in the region of
Toronto. While there were numerous ad hoc teams spread through the city and a
number of psychiatrists who provide ad hoc consultation, there was no program
dedicated to LTCH’s in southeast Toronto.
In 2005, I was successful in securing dedicated funding for the development of
a Geriatric Mental Health Outreach Team that would target residents in LTCH’s
with significant behavioural symptoms.
The funding provided support for a physician, neuropsychologist and
nurse clinician and targeted seven homes in the area of southeast Toronto,
including Heritage Nursing Home, Rekai Centre, Wellesley Central Place, True
Davidson Acres, Main Street Terrace, Belmont House and Nisbett Lodge. Once the funding was secured, I participated
in the hiring of key staff and met with administrators and medical staff from
the assigned homes.
At a local level, the existence of this team has significantly reduced
transfers to emergency departments and led to improved quality of care for
residents in the homes we serve. In
addition, we have been able to significantly enhance the capacity of LTCH’s to
cope with residents displaying responsive behaviours. Finally, we have been able to use the homes
we serve as a platform for research, leading to increased understanding of
neuropsychiatric symptoms in dementia disseminated through publications, grants
and presentations at scientific meetings.
• Annualized funding in the range of
$228,000.00/year from the Toronto Central LHIN
• Sustained MOHLTC funding
• Access to an innovative program for
residents in assigned long term care homes.
• Reduced transfers to emergency
departments.
• Consistently met ministry targets
(200—300 visits per month)
• Letters of support from DOC’s and
administrative staff
• Increased capacity of staff within
LTCH’s to deal with problem behaviours
• Increased capacity of front line
staff in homes
• Increased capacity of trainees to
manage patients with difficult behaviours
• Improved care and quality of life for
residents and their families
• Positive feedback from a satisfaction
survey conducted in 2009
• Training site for students, residents
and allied health personnel
• Peer and non-peer reviewed funding
from national agencies (Brian Canada, CIHR, Alzheimer society of Canada)
• Part of national research initiatives
(CIHR neurodegenerative disease platform, neuropsychiatric symptoms).
• Publications in seminal journals
(psychiatric services, cortex, neurology, dementia and geriatric cognitive
disorders)
• Presentations at local, regional,
national and international scientific meetings (CAGP, AAGP, OLTCA meeting)
2012
Jul 1 – 2013 Jun 30 Psychogeriatric
service development in the city of Toronto (Creation of the Toronto Geriatric
Mental Health Outreach Network).
I was appointed clinical care co-ordinator for the Division of Geriatric
Psychiatry in 2002. The purpose of this
role was to improve psychogeriatric clinical service delivery in the city of
Toronto, specifically in the downtown core where services had been documented
to be quite fragmented. I led number of
meetings which were attended by key stakeholders, including Ministry of Health
representatives as well as physicians and allied health professionals from a
variety of hospitals throughout the downtown core. At these meetings we discussed how the system
could be improved using innovative approaches.
I reported on our progress every few months at the Geriatric Psychiatry
divisional meeting.
In 2005 federal health accord funds
became available to enhance psychogeriatric services in Toronto. We used these funds to establish an
innovative model of service delivery in which Long Term Care Homes (LTCH’s)
were paired with outreach teams across the city, thus ensuring more equitable
access to care, reducing transfers to acute care and improving the capacity of
LTCH’s to deal with responsive behaviours.
A number of new committees were formed, including the Long Term
Care/Mental Health Framework Committee and the Geriatric Mental Health Network
Committee. I led the alignment
subcommittee of the LTC/MH committee and thus played a pivotal role in the
development of this system.
I also conducted an important evaluation of the system changes, which was
funded by the Ministry of Health and Long Term Care and which ultimately led to
a key report submitted to the Toronto Central LHIN in 2008. This report has been used by government
bodies in subsequent years to inform policy making at a regional and national
level, including such projects as “Behavioural Supports Ontario”. In addition, the findings of this report have
been published in the scientific literature and presented at national academic
meetings, leading to broader dissemination of these findings at an academic
level. I have been able to continue my
involvement in system issues at a national level as a member of the Board of Directors
of the Canadian Association of Geriatric Psychiatry.
• Development of an innovative model of
care for elderly LTCH residents displaying responsive behaviours.
• Creation of a service framework for
psychogeriatric services in Toronto (LTC/MH framework committee, Creation of a
Geriatric Mental Health Outreach network committee)
• Increased capacity for Toronto based
LTCH’s to deal with responsive behaviours
• Increased federal funding for
psychogeriatric services in Toronto
• Improved care for residents in
Toronto LTCH’s suffering from dementia and related conditions.
• Reduced transfers to emergency
departments.
• Increased knowledge and expertise of
staff in LTCH’s in Toronto.
• Greater involvement of academic
health care centres in LTCH’s.
• Creation of a formal report submitted
to the Toronto Central LHIN in 2008 highlighting the benefits and gaps in the
system.
• Impact of report on health policy in
this area (local and national initiatives in geriatric psychiatry such as the
BSO project, etc).
• Creation of a framework of care, allowing
for implementation of other initiatives (BSO project).
• Lay publications (Toronto Central
LHIN report).
• Scientific presentations at national
meetings (Canadian Association of Geriatric Psychiatry Annual meeting).
• Publications in scientific journals
2. Contributions to the Development of Professional Practices
2012
Jul 1 – 2013 Jun 30 Influencing
Physician Practice.
In my role as the director of Geriatric Psychiatry at St. Michael’s hospital, I
have been able to have a direct impact on the training of physicians who come
through my program. I have been
responsible for developing a number of initiatives that have improved clinical
practice as well as quality of care.
These include;
• Development of a diverse training
program integrating consultation-liaison psychiatry, long term care
consultation and memory clinic training.
• Collaborative approach to care
incorporating behavioural neurology.
• Integration of clinical care with
research through weekly memory disorder clinic meetings.
• Integration of neuropsychological
testing through affiliation with the Toronto Dementia Research Alliance
• Mentoring of elective, co-op and
research students interested in the treatment of patients with
neurodegenerative disorders.
• Trained 2-4 residents per year in
geriatric psychiatry
• Attracted 2-4 elective students per
year interested in geriatric psychiatry
• Over 200 requests/yr for summer
student placements
• Trainees have gone on to pursue
careers in fields such as medicine and graduate school
2012
Jul 1 – 2013 Jun 30 Improving
Community Based Practice.
Through the creation of the Geriatric Mental Health Outreach Network and the
evaluation I conducted, I have been able to have significant influence over
professional practice, specifically as it pertains to outreach to long term
care homes. The new network we
established forged important linkages between long term care homes and academic
teaching hospitals, leading to the adoption of best practices. Furthermore, based on the outcome of the
evaluation, we were able to make specific recommendations to physicians and
teams involved in long term care homes that led to improved clinical
practice. These improvements in clinical
practice have had a direct and lasting impact on the quality of care of
patients and contributed to greater system integration. We were also able to advocate for greater
funding for psychogeriatric services and improved access to inpatient
behavioural beds. The new system created
stronger linkages between long term care homes, emergency departments and
specialty beds, improving system flow and leading to better treatment outcomes.
• Creation of 13 new outreach teams
affiliated with hospital across the city
• Provision of care to 86 LTCH’s
• Improved access to specialty beds
• Addition of new specialty beds
• Adoption of common tools for
assessing patients
• Greater integration between acute
care sector , LTCH’s and the CCAC
2012
Jul 1 – 2013 Jun 30 Influencing
Health Policy and Organizational Decision Making.
Over the years since being involved in the development of psychogeriatric
services in Toronto I have developed a close working relationship with policy
makers. In the early years, I assembled
a team of physicians, nurses, administrators and doctors who came together to
develop strategies for improving the quality of clinical care in downtown
Toronto. In later years, I was pivotal
in the creation of the Long term Care/Mental Health Framework Committee and
chaired the alignment subcommittee. I
have taken a lead role in program evaluation and authored a Ministry of Health
Funded report which led to key recommendations that has guided the development
of psychogeriatric services in down town Toronto. This report has gone on to influence other
national and regional initiatives in this area, such as Behavioural Supports
Ontario. Finally, in recognition of my
work, in 2012 I was elected to the board of directors of the Canadian
Association for Geriatric Psychiatry.
Here, I have continued to have influence over policies and procedures at
a national level.
a. Consulting to policy makers:
i Evaluation of the Toronto Geriatric
Mental Health Outreach Network
ii Behavioural Support Ontario, Toronto chapter
b. Membership in TCLHIN committees
i Long Term Care/Mental Health Steering

3. Exemplary Professional Practice
2012
Jul 1 – 2013 Jun 30 Training the next
generation of geriatric psychiatrists.
Since founding the geriatric psychiatry program at St. Michael’s Hospital, I
have had significant impact on trainees I have mentored, both in the areas of
research and clinical practice. I have
emphasized a balanced approach to clinical practice, one that emphasizes
integrating related disciplines such as neurology and one that is fully
integrated with clinical research. With
the recent achievement of subspecialty status for geriatric psychiatry, I have
been involved in helping to shape the curriculum for new trainees, through my
involvement in the geriatric subspecialty residency committee. As well, I have participated regularly in our
program’s centralized seminar series, thus contributing directly to the
knowledge and expertise of trainees.
Finally, through my recent election to the Board of Directors of the
Canadian Association of Geriatric Psychiatry, I have been able to have
influence over policies and procedures at a national level. These strategies have focused on engendering
interest in geriatric psychiatry and related disciplines among trainees.
• Increased number of subspecialty
geriatric psychiatry residents in Canada
• Consistently recognized as an
excellent training site for residents based on site report data.
• Increased knowledge of geriatric
psychiatry among non geriatric psychiatrists
• Increased interest in clinical
research among trainees.
• Involvement of trainees in
peer-reviewed grants/publications
2012
Jul 1 – 2013 Jun 30 • Increased number of subspecialty geriatric
psychiatry residents in Canada • Consistently
recognized as an excellent training site for residents based on site report
data. • Increased knowledge of
geriatric psychiatry among non geriatric psychiatrists • Increased interest in clinical research among trainees. • Involvement of trainees in peer-reviewed
grants/publications.
Over the course of the past few years, I have mentored several undergraduate
neuroscience students in clinical research.
By working in close collaboration with a dedicated research scientist I
have succeeded in creating an atmosphere where students have an opportunity to
initiate projects as well as participate in them. Thus, interest in co-op placements has
expanded considerably in the past few years, from a few application to
approximately 200 per year. Many of the
students whom I have mentored have gone on to pursue promising careers in
fields such as medicine and graduate school.
• Increased number of applications from
a few to 200 over the years
• Positive testimonials (see teaching
section)
• Students who have gone on to pursue
careers in medicine, graduate school, etc
• Increased involvement of trainees in
poster presentations, publications and grants
