Heatstroke in a chronic schizophrenic patient treated with high-potency neuroleptics

A fatal case of heatstroke occurred in a chronic schizophrenic patient treated with high-potency neuroleptics. The author differentiates heatstroke from other hyperthermic syndromes related to treatment with major tranquilizers and suggests that an awareness of factors that predispose psychiatric patients to the development of heatstroke may aid in its prevention.
