Does physical activity influence semantic memory activation in amnestic mild cognitive impairment?

Psychiatry Res. 2011 Jul 30;193(1):60-2. doi: 10.1016/j.pscychresns.2011.04.001. Epub 2011 May 23.

Abstract

The effect of physical activity (PA) on functional brain activation for semantic memory in amnestic mild cognitive impairment (aMCI) was examined using event-related functional magnetic resonance imaging during fame discrimination. Significantly greater semantic memory activation occurred in the left caudate of High- versus Low-PA patients, (P=0.03), suggesting PA may enhance memory-related caudate activation in aMCI.
