Asterixis is usually bilateral. Occasionally, it may appear unilaterally. Hemiasterixis following infarction of the contralateral midbrain and thalamus is described. Mechanisms of asterixis and brain lesions associated with its unilateral appearance are reviewed. The mesodiencephalon is frequently implicated by the lesion either directly or indirectly, suggesting the importance of this structure in posture regulation.
扑翼样震颤通常为双侧性。偶尔，它可能单侧出现。有关于对侧中脑和丘脑梗死继发偏侧扑翼样震颤的描述。本文回顾了扑翼样震颤的机制及其单侧出现相关的脑病变。病变常常直接或间接累及中脑间脑，提示该结构在姿势调节中的重要性。
