无症状性脑梗塞的研究进展

无症状性脑梗塞是指临床症状轻微或一过性易被忽略,或只有神经系统症状体征,影像学上见到非责任病灶。危险因素与症状性脑梗塞一致。可能影响急性脑卒中的病程、临床表现和预后,是症状性脑梗塞的预兆,可能发展为假性球麻痹、多发梗塞性痴呆。所以对患高血压病或糖尿病的老年人,如发生眩晕、头痛、语言障碍等症状,虽未发现明显体征,也应及时作颅脑CT或MRI检查,以早发现、早治疗。其治疗方案除恢复期缺血性脑血管病的治疗方法外,主要是采用脑卒中二级或三级预防措施。另外,补充维生素B6、B12及叶酸可以降低高同型半胱氨酸血症性缺血性脑血管病的发生。以头痛为首发症状的无症状性脑梗塞脱水剂治疗无效反而加重,加用镁剂后效果明显。

Advances in research on silent cerebral infarct

The silent cerebral infarct is an clinic symptom that is so slight or transitory as to be easily neglected.There are only neural symptoms and signs,but irresponsible infarct focus can be seen on image.The risk factors of silent cerebral infarct may be the same as those of symptomatic cerebral infarct.Such infarct is likely to influence the course,clinic symptom and prognosis of acute cerebral infarct and may foretell symptomatic cerebral infarct and deteriorate into pseudo-global paralysis or multi-infarcte...
