The Link Between Psychotic Disorders and Substance Use

January 01, 2007

Psychotic disorders are a group of syndromes characterized by positive symptoms, including hallucinations, delusions, and thought disorder; and negative symptoms, including mood symptoms, social withdrawal, and reduced motivation. Cognitive deficits also appear with psychotic disorders. Psychotic disorders rank 22nd in the World Health Organization's list of worldwide causes of disability. This ranking is adjusted for the relatively low lifetime prevalence rate for psychosis; the perceived burden of the disease on those affected with psychotic disorders, as well as their relatives and caregivers, is much higher.
