title: Self-injury and violence in people with severe learning disabilities.
abstract: BACKGROUND
  Psychiatry in severe and profound learning disability is essentially behavioural psychiatry. Some clinical and research observations of disorders of behaviour in this group are summarised in this study.
  
  
  METHODS
  After inspection of the literature, I postulated a clinical syndrome of violence and self-injury in the severely learning disabled. A check-list of behavioural symptoms was developed and used in a community survey.
  
  
  RESULTS
  Behaviour, assessed by the check-list, supported the existence of organic behaviour disorder, as did small-scale psychophysiological testing.
  
  
  CONCLUSIONS
  Self-injury is strongly associated with violence, and with severe and profound learning disability. Pathophysiology of violence and self-injury may include high levels of psychophysiological arousal demonstrated by unstable EEGs. Reduction of arousal by antipsychotic medication is associated with clinical improvement in violent and self-injurious behaviours.
