To study the vertigo attacks known as Tumarkin attacks or drop attacks (DA). DA are characterized by sudden loss of balance with or without falls but with preserved consciousness, and they are supposedly triggered by changes in the otolith function of Meniere's disease (MD).
Data from 243 consecutive MD patients were collected into a database of an otoneurologic expert system.
DA was experienced by 72% (n = 173) of the patients with MD. It correlated with visually provoked vertigo. Gait difficulties, tinnitus, and anxiety were more common in the DA group. Long lasting vertigo attacks were more frequently provoked in the DA subjects by physical strain (58% vs 14%), head movements or changes in head position (71% vs 48%), pressure changes (54% vs 12%), or rapid movements in visual surroundings (65% vs 35%) than in the non-DA subjects.
DA are common in MD patients. The abrupt occurrence of DA make them poorly tolerated.
DA are more common in advanced MD.
研究被称为图尔马金发作或跌倒发作（DA）的眩晕发作。DA的特征是突然失去平衡，伴或不伴有跌倒，但意识保持清醒，据推测是由梅尼埃病（MD）的耳石功能变化引发的。
将243例连续性MD患者的数据收集到一个耳神经学专家系统的数据库中。
72%（n = 173）的MD患者经历过DA。它与视觉诱发性眩晕相关。DA组步态困难、耳鸣和焦虑更为常见。与非DA受试者相比，身体劳累（58%对14%）、头部运动或头部位置变化（71%对48%）、压力变化（54%对12%）或视觉环境中的快速运动（65%对35%）更常诱发DA受试者出现长时间眩晕发作。
DA在MD患者中很常见。DA的突然发作使其耐受性较差。
DA在晚期MD中更为常见。
