[Huntington chorea. Review of the most recent aspects of research].

The authors are presenting a review concerning the most visible aspects of the research directed to emphasize that Huntington's Chorea cannot be compared, either clinically or pathologically, to Parkinson's Disease. It is a hereditary disease in which we can discern an alteration of some neurotransmitters, neuromodulators, neurohormones that are not necessarily opposite in respect to pathophysiological findings of Parkinson disease.
