Welcome to the Villeneuve Lab

The Villeneuve Lab is interested in how the brain ages, with a specific focus on factors that modify the association between brain lesions and cognitive performance. Our research is motivated by the fact that more than 25% of older adults are considered cognitively normal despite the presence of beta-amyloid in their brain, a hallmark of Alzheimer’s disease. This fact suggests that other factors interact with beta-amyloid to trigger cognitive deficits in Alzheimer’s disease. It also suggests that actions can be taken to prevent or postpone disease-related symptoms. The main focus of the Villeneuve Lab’s research is therefore to examine the factors that protect against, or worsen, the development of cognitive deficits in age-related neurodegenerative diseases.

We use a multi-tier approach that includes molecular PET imaging, MRI imaging, neuropsychological testing and genetics, combined with analytic tools such as deep learning, lasso regression and partial least squares regression.
