Lab name: FTD & Neuropsychiatry Lab

Theme-Based Group: Aging, Cognition, and Alzheimer’s Disease
Division: Clinical Research

 

The FTD & Neuropsychiatry Lab led by Dr. Simon Ducharme aims to develop clinical and therapeutic tools for neuropsychiatric disorders, focusing on major neurocognitive disorders. We are conducting translational studies using structural and functional imaging in frontotemporal dementia (FTD) to improve early diagnostic markers for this devastating disease. Our group is involved in several national and international neuroimaging studies on dementia, in addition to innovative clinical trials on Alzheimer’s disease and FTD.

Dr. Simon Ducharme has a medical degree from the Université de Montréal and a Masters from McGill University. He completed his residency in Psychiatry at McGill in 2012, and a fellowship in Behavioral Neurology and Neuropsychiatry at Harvard University in 2014.

He has a board certification in Behavioral Neurology and Neuropsychiatry from the United Council for Neurological Subspecialties. He currently works as a Neuropsychiatrist at the Douglas Mental Health Institute. He has a clinical specialty in frontotemporal dementia.

Dr. Ducharme has received over 35 awards of academic or research excellence, including the 2013 Career Development Award from the American Neuropsychiatric Association and is an FRQS-funded clinician-scientist.

His research uses advanced structural brain-imaging techniques to study the longitudinal changes in brain development from childhood to old age, and how it impacts behaviour across health and psychopathology. His current projects aim to develop novel neuroimaging diagnostic and prognostic biomarkers for frontotemporal dementia.

He is the Montreal site PI of the Genetic Frontotemporal Dementia Initiative study and the FTD team leader of the Canadian Consortium on Neurodegeneration in Aging. He is the current chair of the American Neuropsychiatric Association committee on research. Dr. Ducharme is in charge of several clinical trials for Alzheimer’s disease and related dementia.
