Senile chorea

A relatively mild and uncommon disorder that occurs in elderly adults and is characterized by choreic movements.</P> Chorea refers to rapid complex body movements that look well coordinated and purposeful but are, in fact, involuntary.

Chorea was thought suggestive of a grotesque dance.

The term 'chorea' is derived from the Greek word 'choreia' for dancing (as is choreography).</P> Senile chorea is believed by some scientists to be caused by a different gene mutation than that responsible for Huntington chorea (Huntington disease).
