H型高血压与血管性痴呆

脑血管病是我国首位死亡原因。我国脑卒中年死亡人数200多万,在导致脑卒中发生的可控因素中,高血压和同型半胱氨酸升高位居前列,二者在导致脑卒中的发生上具有协同作用,而缺血性脑卒中是导致血管性痴呆的重要病因。我国学者将伴有同型半胱氨酸升高的高血压定义为＂H型高血压＂。我国原发性高血压患者中约有75%为H型高血压。血管性痴呆是指由各类脑血管病所致的痴呆综合征,是继阿尔茨海默病之后第二常见的痴呆。高血压和高同型半胱氨酸血症可引起认知功能障碍,进而导致血管性痴呆的发生,且待患者达血管性痴呆的诊断标准时,常已错过重要的早期干预治疗阶段,故在认知功能明显损害之前就发现并进行干预是非常重要的。现对H型高血压和血管性痴呆的关系做一综述。

H Type Hypertension and Vascular Dementia

Vascular dementia is a dementia syndrome caused by cerebrovascular disease,the second most common type of dementia after Alzheimer＇s disease. High blood pressure and high homocysteine levels can lead to cognitive dysfunction,leading to the occurrence of vascular dementia. Accurate identification and early treatment is very important before cognitive function has been damaged. This article reviews the relationship between H type hypertension and vascular dementia.
