Mathieu Maltais is interested in the role of exercise and healthy lifestyle habits on physical function in older adults. His main focus during his post-doc at the Gerontopole of Toulouse under the supervision of Dr Bruno Vellas was how certain brain pathologies could be related to the evolution of the frailty syndrome. Moreover, he provided new insights regarding how exercise (type, duration and intensity) could be associated with a reduced risk of falls. Furthermore, Dr Maltais examined if exercise could reduce neuropsychiatric symptoms and medication consumption in older adults with dementia living in nursing homes. After two years at the Gerontopole, Dr Maltais’ research interests leans on how exercise and lifestyle habits can be beneficial for elderly individuals, especially those with geriatric syndromes (frailty, dementia, depression). He is currently at the Faculty of Medicine at the University of Sherbrooke under the supervision of Professor Nancy Presse as a postdoc researcher. His work focuses on how nutrition can affect the quality of life (weight, infections and pneumonia) in geriatric patients in a long-term care setting.
