Title: Parkinson's disease of post-encephalitic type following general paresis--an autopsied case. Author: Mitsuyama Y, Fukunaga H, Takayama S. Journal: Folia Psychiatr Neurol Jpn; 1983; 37(1):85-93. PubMed ID: 6884916. Abstract: A clinico-pathological report is given of a case of Parkinson's disease following a general paresis. A 66-year-old male, with no previous history of febrile disease or viral encephalitides, developed a dementing illness. The general paresis was diagnosed from serological studies at the age of 45. He underwent a series of penicillin plus fever therapies as treatment for neurosyphilis. He also developed generalized rigidity and slow mobility 12 years after the diagnosis of general paresis. An anti-Parkinson drug was given. Finally he fell in a state of muteness and became bedridden. He had been hospitalized for 21 years and died from bronchopneumonia. The pathological findings were strikingly similar to post-encephalitic parkinsonism in addition to a healed state of general paresis. They consisted of a widespread nerve cells loss, gliosis and the presence of Alzheimer's neurofibrillary tangles in the substantia nigra. In the cerebral cortex, a diffuse loss of nerve cells and the presence of a weak positive iron reaction were observed. The coexistence of general paresis and post-encephalitic parkinsonism is unusual and the authors discussed the etiological relationship between the two different conditions.[Abstract] [Full Text] [Related] [New Search]
