RT Journal Article SR Electronic T1 Oligoclonal banding in the cerebrospinal fluid of patients with postencephalitic Parkinsonism. JF Journal of Neurology, Neurosurgery & Psychiatry JO J Neurol Neurosurg Psychiatry FD BMJ Publishing Group Ltd SP 790 OP 792 DO 10.1136/jnnp.42.9.790 VO 42 IS 9 A1 Williams, A A1 Houff, S A1 Lees, A A1 Calne, D B YR 1979 UL http://jnnp.bmj.com/content/42/9/790.abstract AB Two recent sporadic cases of progressive Parkinsonism after encephalitis are described. Both patients had two oligoclonal protein bands in their CSF. These bands were not present in patients with idiopathic Parkinson's disease and might, therefore, be useful for diagnostic purposes, particularly when the history of encephalitis is uncertain.
