These extrapyramidal syndromes usually take the form of simple or complex hyperkinesias. Muscle hypertonus is probably also partly extrapyramidal in origin during the second stage of the illness. Despite the remarkable variability of extrapyramidal syndromes occurring with the subacute encephalitides, a parkinsonian syndrome is rare. In the literature dealing with these 3 types of subacute encephalitis, we found only 1 case in which a parkinsonian syndrome temporarily dominated the clinical picture.7We consider the following case of subacute sclerosing leukoencephalitis of van Bogaert interesting in that, during one phase of the disease, the patient showed a prominent parkinsonian syndrome. At one time, this was so dominant that the first diagnostic impression was “postencephalitic parkinsonism.” However, the further course of the illness, including the development of a hyperkinetic syndrome characterized by rhythmic myoclonic jerks, and additional examinations such as electroencephalography and brain biopsy led to a correct diagnosis being established during the patient’s life.}, type={Text}, title={A parkinsonian syndrome in the course of subacute encephalitis}, URL={http://rcin.org.pl/imdik/Content/79653/PDF/publ_9.pdf}, keywords={parkinsonian syndrome, encephalitis}, }
