Who these studies look for
Most require a confirmed diagnosis; memory studies often ask for a study partner who knows you well to attend some visits.
Matching a page like this one never means you qualify. Each research team decides eligibility at screening.
Questions
Why do memory studies need a study partner?
A partner can report day-to-day changes the participant may not notice. Each study explains what the partner is asked to do.
