Patient demographic data

Diagnosis	Gender (M/F) %	Age at death (mean)	PMD (mean hours)	pH (mean)	MMSE (last assessment)
Control (25)	60/40	79.7±7.6	39.1±22.9	6.47±0.28	n/a
PDD (34)	53/47	79.9±6.0	33.5±15.6	6.44±0.34	13 (0–27)
DLB (55)	58/42	81.7±6.5	41.3±28.0	6.37±0.41	13 (0–30)
AD (16)	31/69	88.0±7.8	34.9±23.9	6.30±0.33	10.5 (0–19)

Data are means±SD age in years; PMD, postmortem delay; DLB, dementia with Lewy bodies; PDD, Parkinson’s disease dementia; AD, Alzheimer’s disease. PMD and pH were not significantly different between the groups in the one-way analysis of variance (ANOVA) (p < 0.05).
