    Author: Kotrla KJ, Chacko RC, Harper RG, Doody R.
    Journal: Am J Psychiatry; 1995 Sep; 152(9):1377-9. PubMed ID: 7653698.
    Abstract:
    OBJECTIVE: The authors explored whether personal or family history of major mental illness, negative symptoms, or behavioral measures are associated with positive psychotic symptoms in Alzheimer's disease. METHOD: Fifty-seven patients with Alzheimer's disease were studied prospectively during interviews with the patients and their primary caregivers. RESULTS: Psychotic patients with Alzheimer's disease did not differ in cognitive functioning from nonpsychotic patients with Alzheimer's disease. No association was found between personal or family history of mental illness and psychosis. Asociality was the only negative symptom associated with psychosis. Psychotic patients had more behavioral disturbances. CONCLUSIONS: Positive psychotic symptoms in Alzheimer's disease are not associated with certain aspects of cerebral functioning but are associated with behavioral disturbances.
