Presymptomatic focus
Designed to study disease biology before overt clinical symptoms.
PREVENT-AD
PREVENT-AD is a McGill/Douglas research platform designed to study the earliest biological changes associated with Alzheimer’s disease in cognitively unimpaired older adults at increased risk.

PREVENT-AD provides a unique opportunity to examine how molecular, inflammatory, genetic, imaging, and cognitive markers evolve before the onset of clinical symptoms.
The program integrates longitudinal follow-up, deep phenotyping, biospecimens, neuroimaging, genetics, cognitive assessment, and emerging proteomic technologies to advance prevention-oriented research.
What makes PREVENT-AD distinctive
Designed to study disease biology before overt clinical symptoms.
Repeated measures support trajectory-based analyses over time.
CSF and plasma biomarkers support molecular profiling.
PET and MRI provide spatial markers of amyloid, tau, structure, and function.
Genetic susceptibility is integrated with biomarker and cognitive trajectories.
Findings inform risk stratification and prevention-oriented research.
