Session Title: Choreas (Non-Huntington's Disease)
Session Time: 1:45pm-3:15pm
Location: Hall 3FG
Objective: We report a 75- year-old man with unilateral frontal stroke lesion whose initial and predominant manifestation was hemiballism.
Background: Ballism is a very rare movement disorder caused in most cases by a decrease in activity of the subthalamic nucleus of the basal ganglia resulting in the appearance of ballistic undesired movements of the limbs.
Methods: Neurological examinations revealed hemiballism in his right upper extremity and muscle hypertonia in his lower right extremity. Cranial MRI showed acude lesion wein the left frontal lobe and signs of chronic vascular pathology.
Results: His ballism improved with haloperidol.
Conclusions: In this case an ischemic lesion in the letf frontal lobe may have caused hypofunction of the motor control pathway.
