Oculogyric crises and parkinsonism. A case of recent onset.

Oculogyric crisis in association with postencephalitic parkinsonism has been reported only following encephalitis lethargica (Economo's disease). Generally, it has been assumed that this phenomenon would fade away with the demise of these postencephalitic patients. Therefore, we report a case of recent onset of persistent oculogyric crisis with parkinsonism in a 35-year-old man following an apparent attack of encephalitis in 1972.
