BACKGROUND: Psychiatric and behavioural symptoms in dementia are associated with a range of negative outcomes, including institutional placement and the widespread use of psychotropic drugs in spite of limited evidence for their efficacy. AIMS: To determine the prevalence of psychiatric and behavioural symptoms and the pattern of psychotropic drug prescription in patients with various degrees of dementia. METHODS: A sample of 1,163 non-selected nursing home patients were assessed by means of the Neuropsychiatric Inventory, the Clinical Dementia Rating scale and Lawton's activities of daily living scale. In addition, information was collected from the patients' records. RESULTS: Dementia was found in 81% of the patients and 72% of them had clinically significant psychiatric and behavioural symptoms. The frequencies of symptoms increased with the severity of the dementia. Psychotropic medication was being prescribed to 75% of patients with dementia. There was a significant relationship between the type of drug and the symptom for which it had been dispensed. CONCLUSION: Psychiatric and behavioural symptoms are frequent in nursing homes and the rate increases with the progression of the dementia. Systematic programmes are needed for disseminating skills and providing guidance regarding the evaluation and treatment of these symptoms in nursing homes.
