Educational attainment mitigates hippocampal‐related episodic memory decline in individuals at risk of Alzheimer's disease

Journal of Neuropsychology, Volume 20, Issue 2, Page 394-409, June 2026.
Abstract Ageing and Alzheimer's disease lead to declines in the brain region underlying memory for past events (hippocampus), and subsequently in memory for past events (episodic memory). However, some people show considerable adaptability in maintaining cognitive processes despite brain ageing or disease.
