What this trial studies

This study aims to establish a clinical cohort for the Duke/UNC Alzheimer's Disease Research Center, enrolling individuals aged 25 to 80 with varying cognitive statuses, including normal cognition, mild cognitive impairment, and dementia. Participants will undergo comprehensive assessments, including medical history, physical exams, neuropsychological testing, and various biological sample collections. The cohort will be followed annually for ongoing evaluation and data collection to better understand the impact of age, sex, and genetics on neurodegenerative disorders. The data collected will be de-identified and used to advance research in Alzheimer's disease and related dementias.

Why it matters

Potential benefit: If successful, this study could enhance understanding of Alzheimer's disease and improve early detection and intervention strategies for patients.

How similar studies have gone: Other studies have successfully established similar cohorts, indicating that this approach is both tested and valuable for advancing Alzheimer's research.
