血管性痴呆主要表现为大脑皮质介导的高级功能产生进行性衰退，是在急慢性脑血管病基础上，产生的获得性智能持续性损害。目前血管性痴呆发病人群日益增大，但由于其诊断、辨证及发病机制尚不十分明确，给治疗造成了很大的负担。近年来，通过对血管性痴呆发病机制的研究可知，血管性痴呆的研究正在向多因素、多方向、多学科汇集、多角度思考的方面快速发展。“,”Vascular dementia is mainly caused by the progressive decline of brain cortex mediated advanced functions,is acquired sustained intelligence damage based on acute and chronic cerebrovascular disease.At present,the incidence of vascular dementia is increasing,but because the diagnosis,dialectical and pathogenesis are not very clear,the treatment is still a great burden.It is found through the pathogenesis study of vascular dementia that the study is developing rapidly towards the direction of multi-factor,multi-direction,multi-discipline and multi-perspective.
