  • For subjects ages 45-50, a first-degree relative with a neurodegenerative disease

The main study involves a single visit at which participants will undergo brief cognitive testing, complete lifestyle questionnaires, provide samples of blood and/or cerebrospinal fluid (optional), and undergo genetic testing. No clinical laboratory testing will be done and no results will be communicated to participants. Participants may also choose to participate in a longitudinal sub-study that involves annual or every-other-year visits. To enhance exploration of diagnosis methods, specimens will be banked for sharing with other researchers (in a de-identified manner to ensure participants' privacy).
