Exercise, Dopamine, and Cognition in Older Age

Eric J Juarez et al. Trends Cogn Sci. 2019 Dec.

Abstract

Jonasson et al. investigated whether individual differences in human dopamine receptors (D2R) were related to cognitive performance before and after a 6-month aerobic exercise intervention (compared with active control). While D2R decreased (perhaps counterintuitively) with exercise, there was no relationship between D2R and working memory at baseline or following exercise.

Keywords: aging; fitness; working memory.
