Abstract

Upbeat nystagmus is a less common type of central vestibular nystagmus that is often transient. It is a vertical jerk-waveform nystagmus with downward slow phases and upward quick phases. In this chapter, we begin by reviewing the clinical features of upbeat nystagmus. Since it can be produced by lesions in a variety locations in the brainstem and cerebellum, we next describe the symptoms and signs that can help to localize the causative lesion. We list the causes of upbeat nystagmus. We then discuss the clinical and imaging findings in Wernicke encephalopathy, which is a common cause of upbeat nystagmus, and we review the management of Wernicke encephalopathy. Lastly, we briefly discuss the medical treatment options for persistent upbeat nystagmus.

欢快的眼球震颤

乐观型眼球震颤是一种不太常见的中枢性前庭眼球震颤，通常是短暂的。它是一种垂直的抽搐波形眼震，具有向下的慢相和向上的快相。在本章中，我们首先回顾向上型眼球震颤的临床特征。由于它可以由脑干和小脑的不同部位的病变产生，我们接下来描述有助于定位病因病变的症状和体征。我们列出了乐观型眼球震颤的原因。然后，我们讨论了韦尼克脑病的临床和影像学表现，这是一种常见的向上眼震的原因，我们回顾了韦尼克脑病的治疗。最后，我们简要讨论了持续性上视性眼球震颤的医学治疗选择。
