Previous diffusion tensor imaging (DTI) research in mild traumatic brain injury (mTBI) patients only concentrated on a limited number of brain regions and a specific cognitive function. Thus, the study aimed to explore the association between DTI findings and cognitive function following mTBI using a meta-analysis. We conducted a search for articles exploring the associations between DTI findings and cognitive outcomes following mTBI published in English in databases (PubMed, Web of Science, EMBASE, Medline, and Google Scholar) before October 2019. ⋯ The study indicated that higher mean diffusivity (MD)/apparent diffusion coefficient (ADC) values in the external capsule (EC) were associated with worse memory. Additionally, higher MD/ADC values in the UF were associated with worse attention, processing speed, and working memory. The present study showed that better white matter integrity (higher FA, lower MD/ADC) might be associated with better cognitive function following mTBI.
