Median age was 69 years, median Montreal Cognitive Assessment score was 25, median independence in activities of daily living was 100% for basic and 93% for instrumental activities. Spousal study partners predominated; participants were often male, White, and more educated. Milder disease stages predominated, yet cohorts reflect clinical presentation.</jats:p></jats:sec><jats:sec><jats:title>Discussion</jats:title><jats:p>Data will be shared with the global scientific community. Within‐disease and disease‐agnostic approaches are expected to identify markers of severity, progression, and therapy targets. Sampling characteristics also provide guidance for future study design.</jats:p></jats:sec>
