Abstract
The aim of this study was to assess the efficacy of the serotonin-dopamine antagonist perospirone in treating aggressive and agitated behavior in patients with dementia. Six patients were referred to the outpatient clinic of Ishizaki Hospital and were followed for 6 weeks. Their psychiatric diagnoses were made using the DSM-IV. Their behavioral symptoms and degrees of cognitive impairment were measured using the Behavioral Pathology in Alzheimer's Disease (BEHAVE-AD) and the Mini-Mental Examination State. The changes in BEHAVE-AD scores were investigated. Maximum benefit was achieved at a mean perospirone dose of 9.0 mg/day. No patient experienced severe adverse effects. Post-hoc analysis showed significant improvement in the total BEHAVE-AD and aggressiveness subscale scores within 2 weeks. This study suggests that perospirone is effective in improving aggressive and agitated behavioral symptoms in demented patients and is safe to use in elderly patients.
