Memory complaints and APOE-ε4 accelerate cognitive decline in cognitively normal elderly

Abstract

Both memory complaints and APOE-epsilon4 allele carriage predict cognitive decline at an early stage. This finding highlights the importance of subjective memory complaints, which are important even at an early stage when objective tests are still unable to detect cognitive deficits and are especially important for elderly carriers of the APOE-epsilon4 allele because they have an additional risk.
