Dr Desmarais has acquired clinical expertise in the field of cognitive neurology, more specifically in non-Alzheimer neurocognitive disorders such as frontotemporal lobar degeneration and alpha-synucleiopathies. He is particularly interested in neuropsychiatric and behavioural manifestations of neurodegenerative disorders as well as their pharmacological treatments. 

Dr. Desmarais' research endeavours explore the clinico-radiological and clinico-pathological neural correlates between neuropsychiatric manifestations and white matter changes on brain MRI in frontotemporal lobar degeneration.

Current research projects:

• Clinico-radiological and clinico-pathological correlations of white matter hyperintensities on T2-weighted imaging with neuropsychiatric manifestations in frontotemporal lobar degeneration.
• Study on the association of post-traumatic stress disorder with neurodegenerative disorders.
• Assessment of quality of care based on patient-centred outcomes in cognitive neurology.
