Difficulties developing evidence-based approaches in learning disabilities

What are the effects of drug treatments for panic disorder? This article is part of a new initiative in Evidence-based Mental Health, namely the serialisation of chapters of Clinical Evidence (a summary of the best available evidence on common clinical interventions updated regularly by the BMJ Publishing Group). This article is based on material presented in: Kumar S, Oakley-Browne M. Panic disorder. Clinical Evidence 2002; 8: 1003-9. For this review, Clinical Evidence searched and appraised material published until May 2002. Studies with follow up periods of less than 6 months were excluded.
