摘要

我们报告一个病例阵发性低节奏眼球震颤，共济失调，构音障碍在谵妄的背景下，患者严重低镁血症。广泛的检查没有提供其他解释。她的发作在镁替代治疗开始后48小时内消退，但患者仍保持神志不清和共济失调，6周后逐渐完全恢复。低镁血症很可能是由于长期摄入质子泵抑制剂（PPI）所致。阵发性下拍性眼球震颤是罕见的，到目前为止，只有一致的描述与各种原因的低镁血症有关。

Paroxysmal downbeat nystagmus, a case report and a review of the literature.

We report a case of paroxysmal downbeat nystagmus, ataxia, and dysarthria in the context of a delirium in a patient with severe hypomagnesemia. Extensive workup did not provide alternative explanations. Her attacks subsided within 48 h after the start of magnesium substitution and the patient remained confused and ataxic with a gradual but full recovery over 6 weeks. Hypomagnesemia resulted most probably from long-term proton-pump inhibitor (PPI) intake. Paroxysmal downbeat nystagmus is rare and has so far only been consistently described in association with hypomagnesemia of various causes.

期刊介绍： Journal of Vestibular Research is a peer-reviewed journal that publishes experimental and observational studies, review papers, and theoretical papers based on current knowledge of the vestibular system. Subjects of the studies can include experimental animals, normal humans, and humans with vestibular or other related disorders. Study topics can include the following: Anatomy of the vestibular system, including vestibulo-ocular, vestibulo-spinal, and vestibulo-autonomic pathways Balance disorders Neurochemistry and neuropharmacology of balance, both at the systems and single neuron level Neurophysiology of balance, including the vestibular, ocular motor, autonomic, and postural control systems Psychophysics of spatial orientation Space and motion sickness Vestibular rehabilitation Vestibular-related human performance in various environments
