[Chronic non-progressive form of chorea].

This is a report on a 65-year-old man with a 58-year-long history of choreic hyperkinesis with a wave-like course of the disease without its progression and without the development of intellectual disturbances. The authors discusses whether it is justified nosologically (in view of similar reports in the foreign literature) to refer this case to a distinctive form of nonprogressive chronic hereditary chorea distinctive from Huntington's chorea.
