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.

| New Article from the Villeneuve Lab April 2024 Ting Qiu’s article “Structural white matter properties and cognitive resilience to tau pathology” has been published in Alzheimer’s & Dementia. Our study demonstrates that the macro- and micro-structural properties of the brain’s white matter contribute to cognitive resilience against Alzheimer’s disease, particularly against tau pathology. Our results further reveal that education and vascular health aid in optimizing white matter properties, offering potential strategies to mitigate cognitive decline. [Papers] |

| New Article from the Villeneuve Lab February 2024 Frédéric St-Onge’s article “Tau accumulation and its spatial progression across the Alzheimer’s disease spectrum” has been published in Brain Communications. We describe the inter-individual heterogeneity in regional tau pathology in the brain across the Alzheimer’s disease spectrum. We found that a measure of the spatial extent of tau pathology is better at identifying certain associations with cognition. [Papers] |
