However, PGC1α mRNA levels were unaltered between cohorts for both neurotypes (PPN‐cholinergic, Control: 981 ± 17.5; DLB: 973 ± 15.8; PDD: 943 ± 20.4; p > 0.05; Figure 4c; LC‐noradrenergic, Control: 742 ± 19.3; DLB: 825 ± 19.2; PDD: 769 ± 17.9; p > 0.05; Figure 4d). This evidence concerns the gene PPARGC1A and Lewy body dementia.
