title: A study of aggression among referrals to a community-based psychiatry of old age service.
abstract: OBJECTIVE
  The aims of the study were to examine the prevalence of aggressive behaviour in a non-selected community-based population, to identify clinical and sociodemographic variables associated with aggression and to examine the relationship between aggression and outcome at 2-year follow-up.
  
  
  METHODS
  Case series, using the Ryden Aggression Scale as a retrospective measure of aggression.
  
  
  METHODS
  A community-based specialist psychiatry of old age service.
  
  
  METHODS
  All referrals to the service over a 3-month period.
  
  
  RESULTS
  Of the 42 subjects included in the study, 25-patients had a diagnosis of dementia. Aggressive behaviour was reported in 18 patients, this being verbal only in nine cases and both verbal and physical in nine cases. Sexual aggression and self-injurious behaviour were each reported in one case only. Aggression was found to be positively associated with a diagnosis of dementia and high physical dependency but was not found to be associated with age, sex, physical illness or the use of psychotropic medication. At 2-year follow-up, aggressive patients were found to have a higher rate of admission to psychiatric inpatient or residential care and tended to have a higher use of neuroleptic drugs.
  
  
  CONCLUSIONS
  These findings suggest that aggression is a significant problem for community-based elderly people and their carers, may increase the likelihood of admission into long-term care and that a reliable instrument to measure aggression would be useful in the clinical assessment of this population.
