Synopsis

Encephalitis refers to direct inflammation of brain tissue. Patients present with abnormalities in brain function, altered mental status, personality changes, behavioral changes, sensory deficits, motor deficits, and speech disorders. Other manifestations include hemiparesis, flaccid paralysis, seizures, and paresthesias.

Encephalitis is often secondary to a virus but may be caused by bacteria, fungi, or toxins. Patients with encephalitis may also have concomitant meningitis. Encephalitis is a frequent complication after stem-cell transplantation. Borna disease virus 1 (BoDV-1) may be a cause of severe encephalitis, and cases of transmission via organ transplantation have been observed. It may also be caused by autoimmune, inflammatory, or paraneoplastic conditions.
