The study, published in JAMA Neurology, measured memory performance, brain structure according to lower hippocampal volume and the presence of amyloid – brain plaques associated with Alzheimer’s disease.

“Our objectives were to compare age, sex and APOE ε4 effects on memory performance, hippocampal volume and amyloid positron emission tomography (PET) across the adult lifespan,” write the authors.
