[Virologic and immunologic considerations in Parkinson's disease]

The investigations related to the etiological role of various viruses in parkinson's Disease are in progress. The role of influenza virus virus was implied, although not definitely proved in post-encephalitic parkinson's Disease. Recent virological and immunological studies are concentrated on influenza and Herpes simplex viruses in idiopathic Parkinsonism. However the evidence obtained is conflicting. More elaborate and detailed research is needed to elucidate the relations between Parkinsonism and the viruses; especially the Herpes simplex virus.
