TFAM and Lewy body dementia: It is noteworthy that significantly lower levels of TFAM mRNA copies were seen in single LC‐noradrenergic compared to individual PPN‐cholinergic neurons, a consistent observation per neurotype, regardless of whether measures occurred in neurological‐control (PPN‐cholinergic:1961 ± 37.7; LC‐noradrenergic: 1520 ± 16.4), DLB (PPN‐cholinergic: 1910 ± 28.1; LC‐noradrenergic: 1526 ± 17.7) or PDD‐derived neurons (PPN‐cholinergic: 1181 ± 19.2; LC‐noradrenergic: 1392 ± 18).
