Summary: APOEe4, a gene associated with Alzheimer’s disease risk, doesn’t appear to directly affect memory performance or brain activity in older adults without cognitive impairment. However, the gene does seem to influence brain regions and systems that older at-risk adults activate to support successful memory recall.

Researchers at McGill University and the Douglas Mental Health University Institute, in collaboration with the StoP-AD Center, have published a new paper in the Journal of Alzheimer’s Disease, examining how a known genetic risk factor for late-onset Alzheimer’s disease (AD) influences memory and brain function in cognitively intact older adults with a family history of AD.
