    General Discussion
    Rasmussen's encephalitis is a rare disorder of the central nervous system characterized by chronic inflammation (encephalitis) of one hemisphere of the brain. As a result, the patient undergoes frequent episodes of uncontrolled electrical disturbances in the brain that cause convulsive seizures (epilepsy). Symptoms, including paralysis of one side of the body (hemiparesis) and mental retardation usually progress over a period of a year or more. Although the exact cause of this disorder is not known, it is thought to be an autoimmune disease resulting from the presence in the brain of foreign immune system cells that cause the inflammation and the brain damage.

    It occurs mostly, but not only, in children under the age of ten years, and the course of the disease is most severe during the first 8 to 12 months. After the peak response is reached, the progression of this disorder appears to stop and the patient is left with neurological deficits.
