Association of Apathy with Amyloid‐β and Tau in Cognitively Unimpaired Older Adults: Findings from the Harvard Aging Brain Study

Apathy is one the most common neuropsychiatric symptoms (NPS) in Alzheimer’s disease (AD) and is associated with elevated AD pathology in cognitively impaired individuals. However, it remains unclear if apathy is associated with AD pathology, specifically amyloid‐β and tau, in cognitively unimpaired (CU) older adults. Therefore, we examined cross‐sectional relationships between apathy and neuroimaging AD biomarkers in CU older adults from the Harvard Aging Brain Study (HABS).
