短暂性脑缺血发作的中西医病机探析

Discussion on the Pathogenesis of Traditional Chinese Medicine and Western Medicine for Transient Ischemic Attack

短暂性脑缺血发作(Transient ischemic attack,TIA)是指一般持续10~15 min,不遗留神经功能缺损的症状和体征,发作后通常会在1 h内完全缓解。西方医学界普遍认为TIA是由脑或视网膜局灶性缺血所导致的。中医学称之为中风先兆。大约有三分之一的患者最终会发生中风,所以研究中风先兆对于预防中风的发生具有重大意义。但迄今为止,对于中风先兆的病机,中医学界并未达成共识。

Transient ischemic attack(TIA)refers to generally lasting 10 to 15 minutes,without leaving behind the symptoms and signs of neurological deficits,usually complete remission within 1 hour after the attack.Western medical circles generally believe that transient ischemic attacks are caused by focal ischemia of the brain or retina.Traditional Chinese medicine calls it a premonitory apoplexy.About one-third of patients will eventually have a stroke,so studying the aura of stroke is of great significance to prevent the occurrence of stroke.But so far,the traditional Chinese medicine community has not reached consensus on the pathogenesis of stroke aura.
