[Results] Kaplan-Meier curves for psychosis development were very similar between the two groups and the Cox proportional hazard model revealed an adjusted hazard ratio of 0.87 (95% confidence interval 0.48-1.60). The changes in MMSE and WMS-1 (auditory memory) were significantly better with donepezil than in placebo. In the subgroup analysis, donepezil provided a hazard ratio of 0.31 (0.11-0.86) against psychosis in 48 weeks for apolipoprotein e4 non-carriers.
[Conclusions] Although donepezil provided beneficial effects on PPQ, MMSE and auditory WMS score changes in two years, it had no prophylactic effect on development of psychosis in PD. Apolipoprotein e4 may suppress the anti-psychotic effect of donepezil.
