Ballismus
Ballismus is considered to be a variant of chorea, with typical clinical appearance of irregular, vigorous limb movements with large amplitude. Most frequently it presents in form of a hemiballism. The diagnostic workup is based on the imaging (preferably MRI) of subthalamic nucleus and neighbouring basal ganglia, because of close causal relationship between structural lesions in this area and ballism. The neuroleptics (dopamine antagonists) are the mainstay of a treatment.
Keywords: ballismus, hemiballismus.
