Transient ischemic attacks (TIA) are episodes of abrupt beginning, consisting of subjective or objective neurological dysfunction of short duration, with complete recovery of neurological function in the course of 24 hours. With this definition, the authors carried out a retrospective study of 150 patients suffering from ischemic infarct in the brain in the territory of the middle cerebral artery. Thirty-eight percent of the patients had had TIAs before their cerebral infarct. The symptoms, in order of frequency, were motor, sensory deficits, alterations of speech and vision. Most of the patients had a definite cerebral infarct, occurring one month after the last TIA; the symptoms of both processes were remarkably similar. The authors studied the angiographic characteristics, pharmacological and toxic antecedents, and associated diseases in these patients. The study indicates that TIA may be the first manifestation of cerebral vascular disease.
短暂性脑缺血发作（TIA）起病突然，由持续时间较短的主观或客观神经功能障碍组成，神经功能在24小时内完全恢复。基于这一定义，作者对150例大脑中动脉供血区发生缺血性梗死的患者进行了回顾性研究。38%的患者在脑梗死之前曾有过短暂性脑缺血发作。按出现频率排序，症状依次为运动、感觉障碍、言语和视觉改变。大多数患者在最后一次短暂性脑缺血发作后1个月出现明确的脑梗死；两个过程的症状非常相似。作者研究了这些患者的血管造影特征、药物和毒物接触史以及相关疾病。该研究表明，短暂性脑缺血发作可能是脑血管疾病的首发表现。
