Collected Dataset / MAP_Annual_Followup_visit

All participants agree to annual follow-up and donation of brain, spinal cord, muscle and nerve up on death.

The window for the annual follow up visit is 9 – 16 months from previous visit. Annual follow up data collection event contains cognitive measures, medical history questions, blood pressure, neuro exam, and a visit by the clinician. The Medical history questions bridge the period from previous visit to the current visit. Data collection ends if a participant withdraws from the study or is deceased. We seek to collect brain, spinal cord, muscle and nerve tissue from deceased participants at autopsy.
