Even though dizziness is a common symptom of heat illness, comprehensive evaluation of the vestibular function has not been available in this potentially life-threatening disorder. Three patients developed vertigo about a week after heat exposure. Evaluation showed bilateral impairments of the vestibulo-ocular reflex during head impulses and the signs of vestibulocerebellar dysfunction that included spontaneous downbeat nystagmus, gaze-evoked nystagmus, and positional downbeat nystagmus. Exposure to excessive heat may give rise to delayed vestibulopathy by damaging the vestibulocerebellum.
尽管头晕是中暑的常见症状，但对于这种可能危及生命的疾病，尚未有对前庭功能的全面评估。三名患者在受热一周后出现眩晕。评估显示，在头部脉冲期间双侧前庭眼反射受损，并且存在前庭小脑功能障碍的体征，包括自发性下跳性眼球震颤、凝视诱发的眼球震颤和位置性下跳性眼球震颤。暴露于过热环境可能通过损害前庭小脑而导致迟发性前庭病。
