约75％的卒中综合征是由脑梗塞引起的。在卒中发作前,很多脑梗塞患者均有过局部神经功能缺失发作。神经功能缺失可分为以下四类:(1)短暂脑缺血发作(TIA):突然开始的(数秒或数分钟)局部脑功能障碍发作,持续数分钟、1小时以上或数小时,但不超过24小时;神经功能缺失迅速恢复;无永久性后遗症。(2)短暂全脑缺血发作(TCI):也可用于表示TIA,但用于全脑或普遍脑缺血发作更确切。(3)可逆性缺血性神经功能障
About 75% of stroke syndrome is caused by cerebral infarction. Prior to stroke, many patients with cerebral infarction have had a partial neurological deficit. Neurological deficits can be grouped into the following four categories: (1) transient ischemic attack (TIA): sudden onset (seconds or minutes) of episodes of local brain dysfunction lasting minutes, more than 1 hour, or hours, but not More than 24 hours; rapid loss of neurological function; no permanent sequelae. (2) Transient Ischemic Stroke (TCI): It can also be used to indicate TIA but is more accurate for whole-brain or generalized ischemic attacks. (3) reversible ischemic neuronal dysfunction
