Common motivations included personal family experience with AD and a desire to benefit the African American community. Barriers for LP and MRI included perceived physical risk and claustrophobia, respectively. Brain donation emerged as a unique, family-centered decision rather than an individual one. A high percentage of participants (34%) remained undecided about brain donation due to concerns about family burden during end-of-life transitions and a lack of procedural information.<\/jats:p>\n
