The diagnosis of post-encephalitic Parkinsonism is rarely entertained today. In this paper we discuss eight recent patients, six of whom presented in the last 20 years, that conform to the diagnosis of encephalitis lethargica. The clinical features by which the diagnosis may be made are defined so that a contemporary definition of this disorder may be attained.
