title: Generalised anxiety disorder.
abstract: BACKGROUND
  Up to one in five people may have generalised anxiety disorder (GAD) at some point, and most have other health problems. Less than half of people have full remission after 5 years. GAD may have a genetic component, and has also been linked to previous psychological or other trauma.
  
  
  OBJECTIVE
  We conducted a systematic review and aimed to answer the following clinical question: What are the effects of treatments for GAD? We searched: Medline, Embase, The Cochrane Library and other important databases up to February 2006 (Clinical Evidence reviews are updated periodically, please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA).
  
  
  RESULTS
  We found 52 systematic reviews, RCTs, or observational studies that met our inclusion criteria.
  
  
  CONCLUSIONS
  In this systematic review we present information relating to the effectiveness and safety of the following interventions: abecarnil, antidepressants (imipramine, opipramol, paroxetine, sertraline, escitalopram and venlafaxine), antipsychotic drugs (trifluoperazine), applied relaxation, benzodiazepines, buspirone, cognitive behavioural therapy, hydroxyzine, kava, and pregabalin.
