Acute vertigo of neurological origin may be caused by haemorrhages and tumours in the posterior fossa and, most frequently, by ischaemic infarction in the vertebrobasilar circulation. Urgent diagnosis is necessary to avoid further ischaemic episodes, herniation due to cerebellar oedema and/or fatal brainstem infarction. The history should focus on accompanying neurological symptoms. However, vertigo with cerebellar lesions may be monosymptomatic and then bedside evaluation of oculomotor function is the key to correct diagnosis. This paper discusses the pathophysiology, symptomatology and clinical evaluation of acute vertigo of neurological origin.
神经源性急性眩晕可能由后颅窝出血和肿瘤引起，最常见的是椎基底动脉循环缺血性梗死。为避免进一步的缺血发作、小脑水肿导致的脑疝和/或致命的脑干梗死，必须进行紧急诊断。病史应重点关注伴随的神经症状。然而，小脑病变引起的眩晕可能是单症状的，此时床边动眼功能评估是正确诊断的关键。本文讨论神经源性急性眩晕的病理生理学、症状学和临床评估。
