Abstract
BACKGROUND: The neuropsychiatric symptoms of dementia, including aggressiveness, agitation, depression, and apathy are often treated with psychotropic drugs and are a frequent reason for hospitalization, placing an economic burden on the health care system. International guidelines recommend syndrome-specific pharmacotherapy. We studied the question whether drug-prescribing practices are, in fact, syndrome-specific. METHODS: In a cross-sectional study in 18 homes for the elderly in Berlin, we used syndrome-specific scales to determine the prevalence of apathy, depression, and aggressiveness and the quantity of psychotropic drugs prescribed, in defined daily dosages (DDD), among 304 demented inhabitants. The diagnosis of dementia was ascertained by chart review and confirmed by administration of a mini mental status test. RESULTS: More than 90% of the demented patients had neuropsychiatric symptoms, most commonly apathy (78%). 52% were treated with neuroleptic drugs, 30% with antidepressants and 17% with anti-dementia agents. There was no significant difference between the frequency of neuroleptic treatment given to apathetic and depressed patients and that given to aggressive patients (chi(2) = 7.03; p = 0.32). CONCLUSION: Although our sample of patients was not representative, these findings suggest that neuropsychiatric symptoms in demented patients are not being treated in syndrome-specific fashion. This is troubling, because neuroleptic medications administered to demented patients can have serious adverse effects, including an elevated mortality. The German guidelines for the treatment of neuropsychiatric disturbances were recently published; the findings presented here suggest that their implementation would be advantageous.
