title: Atypical antipsychotics in the elderly.
abstract: BACKGROUND
  Although their primary purpose is to treat psychosis, antipsychotics are commonly prescribed for the elderly to treat the behavioural disturbances and agitation associated with dementia. Such use is controversial. Atypical antipsychotics cause fewer extrapyramidal sideeffects than the older drugs in younger adults, but the evidence base for their efficacy and tolerability in the elderly is poor. The aims of this study were to determine the prevalence of atypical antipsychotic prescribing for the elderly, the indications for use and documented side-effects.
  
  
  METHODS
  The medication cards of all patients from 19 Trusts, occupying a psychiatric bed for the over 65s, were screened during one week in March 2000. Data were collected by pharmacists from the clinical notes.
  
  
  RESULTS
  Half of those prescribed an antipsychotic received an atypical, and risperidone was the one most commonly prescribed. Half the sample had a diagnosis of dementia. Documented side-effects from the atypical were uncommon.
  
  
  CONCLUSIONS
  Atypicals are frequently prescribed as first-line antipsychotics for behavioural problems associated with dementia, despite the poor evidence base for their efficacy and safety in this population. Undermonitoring of side-effects may remain a problem.
