P2-420: CAUDATE NUCLEUS VOLUMES RELATE TO PROCESSING SPEED IN HEALTHY ADULTS: RESULTS FROM THE FRAMINGHAM HEART STUDY

Reduction of gray matter (GM) volumes in numerous brain regions is part of the cognitively normal (“healthy”) aging process. Aging, even in the absence of clinically apparent cognitive deficits, is associated with cognitive change, particularly declining performance in processing speed. While some studies have reported relationships between regional GM loss and processing speed deficits in various disease states, including Huntington's disease...
