JAMA Neurol:非痴呆人群脑内动脉粥样硬化不会导致认知衰退

2019-12-25 MedSci MedSci原创

研究认为,在非痴呆症人群中,颅内动脉粥样硬化斑块或狭窄与脑β-淀粉样蛋白沉积无关

颅内动脉粥样硬化性疾病(ICAD)是脑卒中的重要病因,近年来也被认为是全因性痴呆的重要危险因素,但其与认知功能的关系尚不完全清楚。

300名70-90岁无痴呆症的成年人接受脑florbetapir正电子发射断层扫描(ARIC-PET)研究,通过高分辨率血管壁磁共振成像显示颅内动脉粥样硬化病变的存在、频率和狭窄程度以评估ICAD与认知的关系。

300名受试者,平均年龄76岁,132名非裔美国人,167名女性,94名携带载脂蛋白E 4等位基因。在105名参与者(35%)中发现了ICAD,与颅内斑块人群相比,斑块人群皮质标准化摄取值比率(SUVR)较高(1.34 vs 1.27)。在校正模型中,ICAD的存在(OR:1.20)和频率(1.10)与SUVR的升高无显著相关性。此外,颅内血管中度狭窄(定义为>50%狭窄)与SUVR升高无关(aOR:2.33)。

研究认为,在非痴呆症人群中,颅内动脉粥样硬化斑块或狭窄与脑β-淀粉样蛋白沉积无关。
