Objective and method: This paper describes the overlap between reactive (psychogenic) psychosis and other brief psychotic episodes, and explores the gradual disappearance of reactive psychoses as a distinct nosological entity from international classifications. Clinical and conceptual issues concerning reactive psychosis are examined on the basis of a critical review of major classical and modern papers. A brief illustrative case history is also provided.
Results: Reactive psychoses are conceptualised as severe disturbances of mental state, on occasion chameleon-like in their shifting form and content, arising in response to a stressful event or life situation. Reactive psychoses have an abrupt onset and usually run their course to complete resolution in a matter of days or weeks. Precipitants include overwhelming fear, threat of imminent destruction, social isolation (as can occur with imprisonment, immigration or deafness), bereavement and intense sexual or interpersonal conflicts. The emergence of a reactive psychosis usually occurs against the background of a predisposing vulnerability in terms of personality disorder, organic impairment, or a history of sensitising experiences, occasionally operating in combination.
Conclusions: The increasing failure to recognise reactive psychoses diminishes clinical psychiatry because it removes an important opportunity for understanding mental disorder in terms of an integration, and totalisation, of developmental history, psychological makeup, social context and current realities, and in so doing lessens our awareness of the links between psychosis and our common humanity.
