From decreased alertness and apathy to agitation, suspicion, and hallucinations, a wide range of psychological symptoms may sometimes point toward serious medical disorders. Helping clinicians "think outside the mental health box," James Morrison provides a clear and systematic guide to the effects upon mental status of 60 health conditions, including heart disease, cancer, and stroke. This practical book will help readers hone their diagnostic skills and recognize when a physician's evaluation may be urgently needed.
