Welcome to the PREVENT-AD Open Data Repository

This repository is intended for public users

If you are a researcher (faculty position) or a physician, you are eligible for access to the more comprehensive registered repository. That version of the dataset features more extensive content, including PET scans and various clinical data, in addition to more recent results.

The PREVENT-AD (Pre-symptomatic Evaluation of Experimental or Novel Treatments for Alzheimer's Disease) cohort is composed of cognitively healthy participants over 55 years old, at risk of developing Alzheimer's Disease (AD) as their parents and/or a sibling were/are affected by the disease. These 'at-risk' participants have been followed for a naturalistic study of the presymptomatic phase of AD since 2011 using multimodal measurements of various disease indicators. Two clinical trials intended to test pharmaco-preventive agents have also been conducted.

The PREVENT-AD research group is periodically releasing data through registered access with the intention to contribute to the community's growing understanding of AD pathogenesis.
