Our understanding and treatment of mental disorders is primitive. Why is that? The burden on our society is huge. A quarter of women will have an episode of depression at some stage in their lives (it’s about half that for men). Most will never reach a doctor or be diagnosed. About 40 per cent of those who do won’t respond to the first antidepressant they are prescribed, and about 60 per cent of those won’t respond to the second. About half of schizophrenics will get better or manage to live reasonable lives: the other half will relapse or never recover in the first place. Anorexia nervosa claims the lives of more patients proportionately than any other mental disorder. But mental disorders are only one category – a rather artificial one – of brain disorders.
