Its hallmarks include paralysis of oculomotor function and marked sleepiness or coma. Survivors developed a parkinsonism-like illness.Encephalitis lethargica refers to an epidemic form of encephalitis, or brain inflammation. Although there have been no significant outbreaks of this condition since the 1920s, infrequent isolated cases continue to appear. In addition to the typical symptoms of encephalitis, encephalitis lethargica is characterized by an added sense of lethargy and drowsiness.Numerous individuals who overcame the initial disease during the major outbreaks subsequently developed a motion-related condition referred to as post-encephalitic Parkinson's disease."}
