The case notes of 37 patients with neuropathologically confirmed Alzheimer's disease were studied for non-cognitive psychiatric features occurring during the course of the illness. Four (11%) exhibited delusions, five (14%) had visual hallucinations and one (3%) had auditory hallucinations. Two (6%) developed a misidentification syndrome, five (14%) developed non-delusional paranoid thinking and six (16%) had significant depressive symptoms with two (5%) developing major depression. Possible explanations for the wide variation in reported rates of psychotic symptoms in Alzheimer's disease in the literature are discussed.
