There were no significant differences between groups for average age at death (ANOVA, p = 0.33), post-mortem interval (ANOVA, p = 0.54), average age of onset (PSP and AD only, Student’s t-test, p = .45) or percent female (Chi Square, p = 0.89). Average disease duration for AD was significantly longer than for PSP (Student’s t-test, p = 0.002). Standard deviations indicated inside parenthesis.
