Individuals at risk for Alzheimer's disease show differential patterns of ERP brain activation during odor identification.

Behavioral and brain functions : BBF - 31 Jul 2012

Morgan Charlie D, Murphy Claire

Abstract excerpt

BACKGROUND: Studies suggest that older adults at risk of developing Alzheimer's disease may show olfactory processing deficits before other signs of dementia appear. METHODS: We studied 60 healthy non-demented individuals, half of whom were positive for the genetic risk factor the Apolipoprotein E ε4 allele, in three different age groups. Event-related potentials to visual and olfactory identification tasks were...
