Should neurosurgery for mental disorder be allowed to die out?

Abstract

The persistence of psychosurgery within the therapeutic armamentarium of psychiatry is something of an anachronism in the current era of evidence-based medicine. Robust evidence for efficacy does not exist and, indeed, can never realistically be gathered because of the extreme ethical difficulties of carrying out randomised controlled trials in this area. Yet there are undoubtedly patients who remain resistant to all conventional forms of treatment. Should they be denied what is possibly their last hope of recovery? Although the evidence is not watertight, modern neurosurgery is safer than ever before and appears to offer clinically meaningful symptom relief for ‘untreatable’ patients with chronic severe depression or obsessive–compulsive disorder (Matthews & Eljamel, 2003). The debate this month poses the question, ‘Should neurosurgery for mental disorder be allowed to die out?’ Dr Raj Persaud, consultant psychiatrist at the Maudsley hospital, argues in favour of the motion. The case in favour of retaining neurosurgery is made by two consultant psychotherapists, Dr David Crossley (Wrexham) and Dr Chris Freeman (Edinburgh).
