Lifespan longitudinal changes in mesocortical thickness and executive function: Role of dopaminergic genetic predisposition.

Neurobiology of aging - 1 Feb 2025

Miranda Giuseppe G, Gonen Chen, Kraft Jessica N, Rodrigue Karen M, Kennedy Kristen M

Abstract excerpt

Dopamine (DA) signaling is critical for optimal cognitive aging, especially in prefrontal-parietal and fronto-striatal networks. Single nucleotide polymorphisms associated with dopamine regulation, COMTVal158Met and DRD2C957T, stand to exert influence on executive function performance via neural properties. The current study investigated whether longitudinal thinning of mesocortical regions is related to COMT and...
