I really like the Council for Evidence-Based Psychiatry website, in particular their Unrecognised Facts About Psychiatry. They say:
‘Most people assume that psychiatry is just like any other branch of medicine, with objective tests for diagnoses and drug treatments that cure real diseases. In reality, however, psychiatric diagnoses and treatments differ enormously from diagnoses and treatments for say cancer or diabetes, since, for mental disorders, there are no known biological ‘diseases’ for psychiatric drugs to ‘treat’.
Here we highlight various Unrecognised Facts about modern psychiatry which every patient, practitioner and policymaker ought to be aware of.’
