title: Managing the behavioral and psychological signs and symptoms of dementia.
abstract: As the world's population ages, increasing numbers of patients with dementia can be expected, the signs and symptoms of which can be extremely disruptive. In particular, behavioral and psychological signs and symptoms of dementia reduce the quality of life of carers (usually family members) and increase the cost of care. Conventional neuroleptics have been used for many years in the management of disturbed and disruptive demented patients, although there are few well-controlled clinical trials demonstrating their efficacy. The use of the low-potency neuroleptics is associated with orthostatic hypotension, cardiac toxicity, anticholinergic side effects and daytime sedation. The high-potency neuroleptics tend to cause extrapyramidal side effects and akathisia. Clozapine although less likely to cause extrapyramidal symptoms than conventional neuroleptics, can cause orthostatic hypotension and requires continual blood monitoring. Early-phase open trials suggest that risperidone is efficacious in patients with behavioral and psychological signs and symptoms of dementia and that it has a low side-effects profile. Further trials are needed to confirm this, but it is likely that the newer antipsychotics, as typified by risperidone, will lead to safer and more effective management of patients with the disruptive and costly behavioral and psychological signs and symptoms of dementia. Non-pharmacologic interventions may also provide benefit, though controls are rare.
