Out of 1,120 cases with focal cerebrovascular lesions, 102 cases (9.1%) were classified as transient episodes under the heading of reversible ischemic attacks (RIA). RIA comprises classical transient ischemic attacks (TIA), clearing completely within 24 h, usually few minutes or hours, and strokes in which a full recovery takes place over an average of 3 weeks. The clinical definition of transient and/or reversible requires a complete negative neurological examination including the normalization of the EEG and brain scan as well as a normal computed tomography. Even multiple transient episodes quite indistinguishable from classical TIA can be brought about by cerebral tumors. TIA are important symptoms, not a disease in themselves. Hypertension and cardiac disease along with carotid stenosis and/or occlusion seem to constitute the main conditions responsible for an evolution from TIA to completed strokes.
在1120例局灶性脑血管病变病例中，102例（9.1%）被归类为可逆性缺血性发作（RIA）标题下的短暂发作。RIA包括经典的短暂性脑缺血发作（TIA），通常在几分钟或几小时内24小时内完全缓解，以及平均3周内完全恢复的中风。短暂性和/或可逆性的临床定义需要完整的神经系统检查阴性，包括脑电图和脑部扫描正常以及计算机断层扫描正常。即使是与经典TIA难以区分的多次短暂发作也可能由脑肿瘤引起。TIA是重要症状，其本身并非一种疾病。高血压、心脏病以及颈动脉狭窄和/或闭塞似乎是导致TIA进展为完全性中风的主要因素。
