Criticism of the biomedical model of psychiatry that regards mental illness as brain disease has been labelled ‘anti-psychiatry’. Critical psychiatry arises out of so-called anti-psychiatry, but has additional roots in transcultural psychiatry, its alliance with psychiatric user/survivor groups, and the methodological critique of the neuroscientific basis of mental health problems and psychiatric treatment effectiveness. It is not opposed to psychiatry as such and argues for a person-centred shift for practice and research. This article discusses how a more truly biopsychosocial model, which critiques the biomedical model to produce a more relational practice, is needed not only for psychiatry but also for medicine in general.
