title: Transient alternating hemichorea as presenting sign of progressive supranuclear palsy.
abstract: We report the case of a man who developed unilateral alternating chorea four years before presenting a typical clinical form of Steele-Richardson-Olszewski syndrome. It is known that choreic dyskinesias may occur during the course of this syndrome but this is the first account of choreas presenting sign of the syndrome.
