In contrast to their findings, Albasanz and colleagues assessed the postmortem brains of 10 patients with common-form dementia with Lewy bodies (DLB) (i.e., DLB accompanied by AD-related pathology), and found that mGluR1 expression in the cerebrum can decrease with progression of the pathological stages of AD (Albasanz et al., 2005). This evidence concerns the gene GRM1 and Lewy body dementia.
