Table 1.
Subject ages and post-mortem intervals.
| Group | n | Age (yrs) | Age range | PMI (hrs) | PMI range (hrs) |
| YN | 11–13 | 43.2 ± 1.9a | 24–53 | 15.8 ± 2.0 | 3.0–24.0 |
| AN | 24–28 | 83.7 ± 2.1 | 66–104 | 10.8 ± 1.4 | 0.3–23.0 |
| PD | 19–20 | 80.2 ± 2.1 | 66–91 | 11.2 ± 2.3 | 2.0–29.0 |
| AD | 12–13 | 76.8 ± 1.9 | 61–83 | 7.4 ± 1.6 | 3.0–23.3 |
| DLB | 9 | 78.3 ± 1.9 | 70–86 | 8.9 ± 2.0 | 1.6–16.3 |
PMI means were similar between groups, and subject ages differed only between young normal specimens and the other groups. Data are expressed as means ± SEM. (ap < 0.05 vs. other groups; abbreviations: AD, Alzheimer's disease; AN, aged normal; DLB, dementia with Lewy bodies; PD, Parkinson's disease; PMI, post-mortem interval; YN, young normal)
