Scientists Identify Three Distinct Paths of Cognitive Decline in Early Alzheimer’s Disease
Researchers analyzing data from 1,629 cognitively normal adults aged 65‑85 identified three distinct trajectories of cognitive decline in preclinical Alzheimer’s disease: stable, slow, and fast. Approximately 70% of participants, including most with elevated amyloid, remained stable over a median six‑year follow‑up, while higher baseline p‑tau217, smaller hippocampi, and APOE e4 increased risk of rapid decline. The study shows that amyloid alone does not predict decline and that current secondary‑prevention trials may be underpowered if they enroll many stable individuals. These findings suggest trial designs should target participants likely to deteriorate.
