Frequency of psychosis by ApoE e4 carrier status and dementia severity. Mini Mental State Examination (MMSE) score was used to classify AD patients as mild (MMSE>19, n=103), moderate (MMSE=12-19, n=121), or severe (MMSE<12, n=42). Separate multiple logistic regression analyses were performed for each severity category, with presence of psychosis as dependent variable and the following independent variables (in addition to e4 carrier status): age, sex, educational attainment, and MMSE. *Only at the severe stage was the presence of e4 significantly associated with psychosis (odds ratio [OR]=16.61, 95% CI=2.11-130.51, P=.008).
