Interictal psychosis after stroke with forced normalization.

摘要

SIR: The World Health Organization defines a stroke as rapidly developing clinical signs of a focal (or global) disturbance of the cerebral function, with symptoms lasting 24 hours or longer or leading to death, with no apparent cause other than of vascular origin. A stroke represents a major public health problem, but relatively little work has been directed toward identifying and treating the common neuropsy-chiatric disorders occurring after stroke.1 Psychosis is a rare complication of stroke, while 2% to 7% people with epilepsy have been reported to suffer from psychosis. The prevalence of psychosis in patients with temporal lobe epilepsy and/or refractory epilepsy varies from 10% to 19%, in most studies. Forced normalization is often observed in psychosis of epilepsy.
