亚临床脑血管病(sCVD)在老年人中非常普遍。sCVD的主要神经影像学表现包括T2加权MRI上的白色高信号和无症状脑梗死,以及梯度回波或磁敏感加权MRI上的脑微出血。在本文中,我们将审查sCVD的流行病学,目前的证据,最佳的医疗管理,以及sCVD研究的未来方向。许多流行病学研究表明,sCVD,特别是WMH,是痴呆、卒中、卒中后不良结局、步态不稳、晚年抑郁和死亡的重要危险因素。sCVD的有效治疗可能对相当一部分美国老年人的大脑健康产生重大影响。尽管sCVD与许多血管风险因素(如高血压或高脂血症)之间存在联系,但sCVD的最佳药物治疗仍不确定。鉴于sCVD积极医学管理的风险与获益的临床平衡,需要临床试验来检查务实的循证方法来管理sCVD。这样的试验可以为如何管理内科医生和神经科医生在实践中面临的常见临床情况提供急需的指导。
Subclinical cerebrovascular disease (sCVD) is highly prevalent in older adults. The main neuroimaging findings of sCVD include white matter hyperintensities and silent brain infarcts on T2-weighted MRI and cerebral microbleeds on gradient echo or susceptibility weighted MRI. In this paper, we will review the epidemiology of sCVD, the current evidence for best medical management, and future directions for sCVD research. Numerous epidemiologic studies show that sCVD, in particular WMH, is an important risk factor for the development of dementia, stroke, worse outcomes after stroke, gait instability, late-life depression, and death. Effective treatment of sCVD could have major consequences for the brain health of a substantial portion of older Americans. Despite the link between sCVD and many vascular risk factors, such as hypertension or hyperlipidemia, the optimal medical treatment of sCVD remains uncertain. Given the clinical equipoise about the risk versus benefit of aggressive medical management for sCVD, clinical trials to examine pragmatic, evidence-based approaches to management of sCVD are needed. Such a trial could provide much needed guidance on how to manage a common clinical scenario facing internists and neurologists in practice.
