Neurology:皮质铁沉积或为阿尔茨海默病新的影像学标志物

2014-03-11 佚名 丁香园

表面铁沉积(SS)是中枢神经系统软脑膜下含铁血黄素沉积的影像学或病理学表现,可通过磁共振T2*或SWI序列检测。皮质SS被认为与脑淀粉样血管病(CAA)以及认知功能障碍相关,既往研究显示CAA患者中皮质SS的发生率为60.5%,无痴呆的老年人群中发生率为0.7%,然而其在阿尔茨海默病(AD)以及其他痴呆类型中的研究较少。【原文下载】 因此,来自荷兰的Frederik

表面铁沉积(SS)是中枢神经系统软脑膜下含铁血黄素沉积的影像学或病理学表现,可通过磁共振T2*或SWI序列检测。皮质SS被认为与脑淀粉样血管病(CAA)以及认知功能障碍相关,既往研究显示CAA患者中皮质SS的发生率为60.5%,无痴呆的老年人群中发生率为0.7%,然而其在阿尔茨海默病(AD)以及其他痴呆类型中的研究较少。【原文下载】

因此,来自荷兰的Frederik Barkhof教授进行了一项研究,旨在明确在记忆门诊患者人群中皮质表面铁沉积(SS)的发生率,分布和严重程度,以及其与阿尔茨海默病(AD)可能的相关性。研究显示AD患者皮质SS发生率约为5%,高于普通老年人群,其可能为AD淀粉样病理表现的影像学标志物。该研究发表于2月份的《神经病学》杂志中。

研究纳入了2010年11月至2012年11月行3T核磁扫描的阿姆斯特丹痴呆队列研究中的809例患者(56%为男性,年龄为66± 10岁)。根据人口学,临床和MRI数据,分析了皮质SS的发生率和分布,并计算两位神经放射学家之间SS检出率的一致性。

结果显示,SS检测的一致性很好。在17例患者(2.1%)中,皮质SS病因未知。AD患者(n=168)中SS发生率接近5%,轻度认知功能障碍患者中为2%,其他类型痴呆(n=80)患者中为2.5%。与此相比,在其他疾病人群(n=157)或其他主诉(n=168)患者中没有发现SS。SS的发生与APOE ε4,微出血以及白质高信号相关,且独立于疾病的诊断。

研究者总结认为,记忆门诊中皮质SS的发生率高于普通人群,但低于脑淀粉样血管病人群。AD患者中相对较高的SS发生率表明SS是AD淀粉样病理的一个有意义的影像学表现。然而,作者也提到SS并不是AD的一个敏感性标志物,但其特异性高于脑叶微出血,并且出现SS似乎并不能预测AD的严重程度。研究者指出还需要进一步队列研究来研究皮质SS是否影响患者的预后以及出现SS的患者是否会加速认知功能下降。

JAMA Neurol:早期脑结构改变与阿尔茨海默病遗传易感性相关

美国一项研究表明,早期脑结构改变与阿尔茨海默病遗传易感性相关,并有可能成为阿尔茨海默病预防治疗的靶位。论文11月25日在线发表于《美国医学会杂志·神经病学》(JAMA Neurol)。 此项研究共纳入162例典型发育的2~25个月婴儿,并在睡眠时实施了脑MRI检查。受试婴儿均无阿尔茨海默病以及其它神经或精神疾病家族史。在载脂蛋白E(APOE)ε4携带者和非携带者中对白质髓鞘水部
