Three patients with unilateral asterixis associated with different vascular lesions of thalamus, basal ganglia and internal and external capsules of contralateral hemisphere are described. Unilateral asterixis is a highly indicative sign of focal cerebral lesion. Its pathophysiology is still unknown. It has been postulated that asterixis is a myoclonic phenomenon resulting from malfunction within neuronal circuits of central nervous system responsible for the active maintenance of posture.
本文描述了3例伴有对侧半球丘脑、基底神经节以及内、外囊不同血管病变的单侧扑翼样震颤患者。单侧扑翼样震颤是局灶性脑病变的一个高度指示性体征。其病理生理学仍不清楚。据推测，扑翼样震颤是一种肌阵挛现象，由负责主动维持姿势的中枢神经系统神经元回路功能障碍引起。
