Welcome to PsychEd, the psychiatry podcast for medical learners, by medical learners. In this episode, we’ll explore a topic that we’re sure many listeners are eager to learn about: The Assessment of Major Neurocognitive Disorder, also known as dementia with Dr. Lesley Wiesenfeld who is a Geriatric Psychiatrist and Psychiatrist-in-Chief at Mount Sinai Hospital in Toronto, where she leads the Geriatric Consult Liaison Psychiatry Service. She is also an Associate Professor in the Department of Psychiatry at the University of Toronto.
The learning objectives for this episode are as follows:
Define Major Neurocognitive Disorder (aka Dementia) as per DSM-5 diagnostic criteria
Identify differential diagnoses for cognitive decline and list differentiating clinical features
Outline an approach to the assessment of a patient presenting with cognitive decline, including the role of a comprehensive history, psychometric tools and other investigations [ Relevant PMH/risk factors, ADLs/IADLs to cover on history, psychometric tools such as MMSE, MoCA and tie this back into major cognitive domains when to consider imaging, bloodwork including specialized testing such as ApoE genetic tests]
Classify the major subtypes of Neurocognitive Disorders, their epidemiology, and clinical presentations [ Vascular dementia, Alzheimer’s, Frontotemporal, Lewy Body, Parkinson’s, Mixed dementia - Early onset dementia]
