// Age and reading ability shape white matter development across the lifespan: A cross-sectional study
本研究針對126位7至77歲中文閱讀者，利用擴散張量成像分析白質發展｜發現大多數與閱讀相關的白質纖維呈現非線性年齡變化，分數各向異性（FA）於中年達高峰，部分纖維則呈線性增加｜詞彙閱讀效率與多條雙側白質通路FA正相關，年輕者關係較顯著，老年者則趨向弱化或反轉｜結果揭示中文閱讀者腦白質隨年齡複雜調整，有助理解閱讀流暢性的終身變化。
// This study investigated white matter development related to reading in 126 Mandarin Chinese readers aged 7 to 77 using diffusion tensor imaging. Most reading-related tracts showed nonlinear age effects, with fractional anisotropy (FA) generally peaking midlife, while some tracts increased FA linearly with age. Word reading efficiency correlated positively with FA in several bilateral tracts, especially in younger individuals, but this relationship weakened or reversed in older adults. The results reveal complex, age-dependent changes in the brain’s white matter that support reading fluency across the lifespan in Chinese readers.
