Sleep in Schizophrenia

Polysomnographic studies reveal sleep abnormalities or dyssomnias that are consistently characteristic of patients with schizophrenia. This article describes many of these dyssomnias and discusses their significance. It also discusses the relationship of these dyssomnias to some of the clinical and neuropathologic features of schizophrenia. Finally, it presents an overview of antipsychotic treatments; their effects on sleep; and their potential to facilitate or augment clinical sleep disorders, such as sleep-disordered breathing and restless legs syndrome.
