[Currency of postencephalitic parkinsonism]

A case of postencephalitic parkinsonism is described. The patient, 27 years old, was affected by encephalitis lethargica 15 years prior to the appearance of the extrapyramidal syndrome on the right side of his body. Based on data in the literature, the possibility is discussed that postencephalitic parkinsonism may still be present and may manifest itself sporadically.
