摘要:

脑微出血(cerebral microbleeds,CMBs)是直径为2~10 mm的圆形或椭圆形低密度病变,病 灶周围无水肿,经T2 *梯度回波或SWI检查可以被发现,是脑小血管病的一种病理改变。随着影像学技 术的发展,CMBs在阿尔茨海默病(Alzheimer’s disease,AD)中的检出率不断升高。AD患者CMBs发生率 高于健康人群及痴呆症患者,且主要分布在脑叶。CMBs可以通过参与颅内淀粉样变性和神经元变性, 与载脂蛋白E基因产生关联及影响血脑屏障等方式在AD疾病进展中发挥作用。

文章导读: 本文介绍了AD患者CMBs的流行病学特点和分布特征,探讨了CMBs与AD之间的关系,这为临床筛查认知障碍高危群体提供依据。

Abstract:

Cerebral microbleed (CMB) is a circular or elliptical low-density lesion with a diameter of 2-10 mm, with no edema around the lesion, which can be found by T2 * GRE or SWI. CMB is a pathological change of cerebral small vessel disease. With the development of imaging technology, the detection rate of CMB in Alzheimer's disease (AD) is increasing. The incidence of CMBs in AD patients is higher than that in the healthy and dementia patients, and the CMBs in AD patients mainly located in brain lobes. CMBs play a role in the progression of AD by involving intracranial amyloidosis and neuronal degeneration, being associated with APOE gene, and affecting the blood-brain barrier.

Key words: Cerebral microbleed; Alzheimer's disease; Cognitive function
