Differing patterns of psychiatric impairment in Alzheimer and demented parkinsonian patients.
Psychiatric symptoms were investigated and compared in 95 patients with Alzheimer type dementia (DAT) and in 39 patients with Parkinson's disease with dementia (PD-D). The diagnosis of the dementia and psychiatric disorders was based on DSM III R criteria; dementia stage was assessed using the Clinical Dementia Rating Scale (CDR). PD-D were significantly older than DAT patients. Delirium was more frequent in the advanced stages of both PD-D and DAT, being mainly of the hypoactive type in PD-D and the hyperactive type in DAT. Delusions and hallucinations predominated in the early CDR stages of both illnesses and did not differ between groups; the same was true for depression. The results revealed different psychopathological profiles in DAT and PD-D patients.
