2017年8月,发表在《Circulation》的一项由美国科学家进行的基于人群的研究考察了脑灌注与痴呆风险之间的相关性。

背景:多项横断面研究已经报道,脑低灌注与轻度认知受损和痴呆相关,但是低灌注是否在神经退行性疾病前发生是未知的。研究者前瞻性确定了脑灌注与后续认知功能衰退和痴呆发生的相关性。

方法:2005~2012年,研究者使用二维相位对比磁共振成像(MRI)在基于人群的鹿特丹研究中的无痴呆参与者中检测了脑血流量。研究者使用调整了年龄、性别、人口统计学、心血管风险因素、载脂蛋白基因型的Cox模型,确定脑灌注(mL/100mL/min)与痴呆风险之间的相关性(截至2015年)。研究者考虑了卒中后,对阿尔茨海默病患者进行再次分析。研究者使用线性回归确定了连续2轮有关灌注的检查期间认知表现的改变。最后,研究者调查了该相关性是否受到基线白质高信号严重程度的影响。

结果:4759例参与者(中位61.3岁,55.2%为女性)中,中位随访6.9年,123例参与者发生痴呆(97例阿尔茨海默病)。较低的脑灌注与较高的痴呆风险相关(调整风险比,1.31;95% CI/标准差下降,1.07~1.61),仅有阿尔茨海默病相似,并未因考虑卒中而改变。痴呆与低灌注的风险随着白质高信号严重程度的增加而增高(严重白质高信号:风险比,1.54;1.11~2.14)。平均5.7年后的认知功能再检查中,较低的基线灌注与认知功能衰退加速相关(总体认知:β=?0.029,P=0.003),排除了痴呆的患者后,结果仍然相似,同样,在具有较高体积的白质高信号个体中最具显着性(P=0.019)。

结论:脑低灌注与普通人群认知功能衰退加速和痴呆风险增加相关。
