Among all the problematic suggestions for DSM5, the proposal for a ” Psychosis Risk Syndrome” stands out as the most ill conceived and potentially harmful. It aims to solve a pressing problem in psychiatry- the need for early identification and preventive treatment. Psychotic episodes create tremendous short term impairment and may impact negatively on long term prognosis and treatment efficacy. It would save great suffering if we could get there early and do something useful to reduce the lifetime burden of illness before too much damage is done. But good intentions are not enough.
