目的:我们假设毒性蛋白non-fluent / agrammatic变体原发性进行性失语(nfvPPA)将从早期传播transynaptically中心语言网络中连接的地区造成的发展随着时间的推移萎缩。据我们所知,没有纵向研究证实了这个假设。背景:功能性神经退化的内在连接网络帮助预测在不同疾病的显示模式萎缩镜子健康功能的网络体系结构。网络语言是nfvPPA容易萎缩,这通常是与病理有关。设计/方法:早期的震中是定义在一组早期nfvPPA (n = 10)的分布形态测量学(VBM)分析。从这个区域我们推导出实用言语/语言连接网络的健康对照组。然后我们确定底层与扩散tractography白质纤维。纵向灰质(GM)和白质(WM)变化进行评估34 nfvPPA VBM纵向分析。最后我们进行体积的变化之间的相关性分析病人和健康网络的力量。结果:从震中额下回(IFG)、健康对照组由已知领域的功能连通性网络参与言语/语言的功能。 Tractography delineated the WM pathways between the same regions. Significant longitudinal GM change was found in the left language-related regions and in the right IFG and precentral gyrus and the longitudinal WM change in the correspondent underlying regions. Significant correlations were found between GM changes in patients and the functional connectivity language network and between WM changes and fractional anisotropy along the language tracks. Conclusion: These findings suggest that the pattern of longitudinal progression of atrophy in nfvPPA reflects the anatomy of language functional network and support the hypothesis that the spread of degeneration occurs not only by contiguity but also following specific anatomical and functional network architectures.
