Abstract excerpt

Dopamine D3 receptor (DRD3) is present in the limbic system, which is thought to regulate affect, cognition, and activity. Thus a functional change in the DRD3 gene could in turn affect the cognitive and psychiatric symptoms of dementia of Alzheimer's type (DAT). We investigated a possible association of DRD3 genotype with DAT and the behavioral and psychological symptoms of dementia (BPSD) in mild DAT. The...
