Schizophrenia has varied and ominous symptoms that generally begin in late adoles- cence or early adulthood and usually continue throughout life.1 Most patients have a history of behavioral dysfunction — primarily social and learning difficulties.2 Diagnos- tic features of schizophrenia include auditory hallucinations (generally voices that con- verse with or about the patient) and delusions (often the paranoid belief that external forces are conspiring against the patient). Patients may have some insight that the voices are internal thoughts and that the delusions cannot possibly be true, but these phenom- ena remain persistent and troubling. In addition to these overt psychotic, or “positive,” symptoms, various deficits, or “negative” symptoms, occur, including an inability to pay attention, the loss of a sense of pleasure, the loss of will or drive, disorganization or im- poverishment of thoughts and speech, flattening of affect, and social withdrawal (Ta- ble 1).
