The National Institutes of Health Stroke Scale (NIHSS) measures deficits caused by a stroke, but not all stroke signs are captured on the NIHSS. We determine the symptoms and stroke localization of patients with brain infarction and an NIHSS score of 0.
We studied all patients who presented with acute neurologic symptoms to our stroke center from 2004 to 2008 and had persistent symptoms at the evaluation in the emergency department, an NIHSS score of 0, and an infarct on diffusion-weighted imaging. We characterized the symptoms, signs, lesion location, demographics, and stroke causes.
Twenty patients met inclusion criteria. Symptoms frequently experienced were headache, vertigo, and nausea. The posterior circulation was commonly infarcted in this group. Truncal ataxia was the most common neurologic sign.
Ischemic stroke may cause symptoms that are associated with no deficits on the NIHSS score.
美国国立卫生研究院卒中量表(NIHSS)可测量卒中引起的缺陷,但并非所有卒中体征都能被 NIHSS 捕捉到。我们确定了 NIHSS 评分为 0 的脑梗死患者的症状和卒中定位。
我们研究了 2004 年至 2008 年期间因急性神经系统症状到我们卒中中心就诊且在急诊科评估时仍有持续症状、NIHSS 评分为 0 且弥散加权成像显示梗死的所有患者。我们对症状、体征、病变部位、人口统计学和卒中病因进行了描述。
20 名患者符合纳入标准。常见的症状包括头痛、眩晕和恶心。该组患者常见后循环梗死。躯干共济失调是最常见的神经体征。
缺血性卒中可能引起 NIHSS 评分无缺陷的症状。
