摘要:

目的 应用静息态功能磁共振(rs-fMRI)低频振幅(ALFF)、比率低频振幅(fALFF)和波动幅度百分比(PerAF)3种指标探究阿尔茨海默病(AD)患者脑部自发性神经活动特点。  方法 对36例AD患者和40例健康志愿者分别行静息态fMRI扫描,应用ALFF、fALFF和PerAF方法计算并对比两组脑区改变的差异。  结果 与正常对照组相比较,AD组在双侧尾状核、额内侧回、额上回、直回、前扣带回、嗅皮质,左侧额中回、额下回等区域mALFF值显著增高(P<0.05);在右侧颞中回、颞下回、枕下回、枕中回,双侧距状皮层、楔叶、舌回、枕上回、小脑蚓、楔前叶等区域mALFF值显著减低(P<0.05)。AD组在右侧颞下回、小脑前叶、梭状回,左侧额上回、额内侧回、额中回、额下回、直回、前扣带回等区域mfALFF值显著增高(P<0.05);在双侧舌回,左侧距状皮层、楔叶、枕上回、枕中回、小脑蚓等区域mfALFF值显著减低(P<0.05)。AD组在双侧直回、前扣带回、额内侧回,左侧额上回、尾状核、额中回、额下回、嗅皮质、脑岛等区域mPerAF值显著增高(P<0.05);在双侧距状皮层、楔叶、枕上回、舌回、楔前叶,左侧梭状回、枕下回,右侧顶上小叶、角回、颞中回、颞下回、枕中回等区域mPerAF值显著减低(P<0.05)。  结论 AD患者默认网络(DMN)和视觉网络存在异常脑活动特征,最显著的神经活动在前额叶皮层和视皮层区域。

Abstract:

Objective To investigate the spontaneous neural activity in the brain of patients with Alzheimer’s disease (AD) used 3 indicators of resting state-functional magnetic resonance (rs-fMRI) amplitude of low frequency fluctuation (ALFF), fractional amplitude of low frequency fluctuation (fALFF) and percentage amplitude fluctuation (PerAF). MethodsTotally 36 clinically diagnosed AD patients and 40 healthy volunteers were scanned by fMRI in resting state respectively. ALFF, fALFF and PerAF were used to calculate and compare the changes of brain regions between the two groups.   Results Compared with the normal control group, mALFF value in AD group increased significantly in bilateral caudate nucleus, medial frontal gyrus, superior frontal gyrus, gyrus rectus, anterior cingulate gyrus, olfactive cortex, left middle frontal gyrus and inferior frontal gyrus (P<0.05). mALFF values decreased significantly in the right middle temporal gyrus, inferior temporal gyrus, inferior occipital gyrus, middle occipital gyrus, bilateral calcarine, cuneus, lingual gyrus, superior occipital gyrus,vermis, precuneus and other regions (P<0.05). In AD group, mfALFF value of right inferior temporal gyrus, anterior cerebellar lobe, fusiform gyrus, left superior frontal gyrus, medial frontal gyrus, middle frontal gyrus, inferior frontal gyrus, gyrus rectus and anterior cingulate gyrus increased significantly (P<0.05); mfALFF values decreased significantly in bilateral lingual gyrus, left calcarine, cuneus, superior occipital gyrus, middle occipital gyrus and vermis (P<0.05). In AD group, mPerAF value incr   eased significantly in bilateral gyrus rectus, anterior cingulate gyrus, medial frontal gyrus, left superior frontal gyrus, caudate nucleus, middle frontal gyrus, inferior frontal gyrus, olfactive cortex and insula (P<0.05); mPerAF values decreased significantly in bilateral calcarine, cuneus, superior occipital gyrus, lingual gyrus, precuneus, left fusiform gyrus, inferior occipital gyrus, right superior parietal lobule, angular gyrus, middle temporal gyrus, inferior temporal gyrus and middle occipital gyrus (P<0.05).   Conclusion The default mode network (DMN) and visual network of AD patients are characterized by abnormal brain activity, with the most significant neural activity in the prefrontal cortex and visual cortex.
