The diagnosis of vertigo with analysis of nystagmus in REM sleep

本研究旨在建立快速眼动（REM）睡眠时眼球震颤的诊断方法。5名住院眩晕患者参与。他们在夜间睡眠时做了眼震电图检查。在REM睡眠期间，记录所有患者的快速眼动（REM）。所有外周性眩晕患者在清醒状态下的扫视频率均高于其他状态，而中枢性眩晕患者的垂直性眼球震颤更为明显。这些先前的发现使我们假设我们可以用这种方法区分外周性眩晕和中枢性眩晕。

The present study was undertaken to develop the method of diagnosis of vertigo with analysis of nystagmus in rapid eye movement (REM) sleep. Five inpatients with vertigo participated. They had an examination of electronystagmography in their night sleep. During REM sleep, rapid eye movements (REMs) of all patients were recorded. All patients with peripheral vertigo showed more frequency of saccades towards the direction in the awake state than the other, besides, the patient with central vertigo showed vertical nystagmus remarkably. These previous findings led us to hypothesize that we can distinguish between peripheral and central vertigo using this method.
