Distribution of hippocampal tangle ratings as a function of dementia severity in schizophrenia patients

CDR < 2 (N =46) CDR > 2 (N =52)
Hippocampal tangle rating
Absent 21 (37.5%) 11 (21.2%)
Sparse 25 (44.6%) 19 (36.5%)
Moderate 2 (3.6%) 5 (9.6%)
Severe 8 (14.3%) 17 (32.7%)

Note: Number of subjects within each tangle rating category (percentages of column total in parentheses). For hippocampal neurofibrillary tangles, nonparametric analyses revealed a main effect for dementia severity (χ2 = 7.73, df = 3, p < .05). There was no effect of ApoE4 carrier status (p = .17).
