Asterixis is usually a manifestation of metabolic encephalopathy. It was the only skeletal motor sign in a patient with ophthalmoplegia caused by midbrain infarction; no metabolic abnormality was present. The asterixis was accompanied by signs of damage to the mesencephalic reticular formation. We propose that episodic lapses of postural control by the reticular formation are responsible for midbrain asterixis and suggest that this asterixis is a segmental form of drop attack.
扑翼样震颤通常是代谢性脑病的一种表现。它是一名由中脑梗死导致眼肌麻痹患者唯一的骨骼运动体征；不存在代谢异常。扑翼样震颤伴有中脑网状结构受损的体征。我们提出，网状结构对姿势控制的间歇性失误是中脑扑翼样震颤的原因，并认为这种扑翼样震颤是猝倒发作的一种节段性形式。
