Abstract

Background/Objectives: This systematic review aimed to investigate the causes of dysphagia after stroke through diffusion tensor tractography (DTT) studies. Methods: This review used databases such as Google Scholar, PubMed, and ScienceDirect. Keywords related to stroke, dysphagia, and diffusion tensor tractography were utilized. Seven studies were selected and analyzed. Results: The analysis identified that damage to the corticobulbar tract (CBT) was the most frequently reported cause of dysphagia. Additionally, some studies suggested that damage to the vestibulospinal tract (VST) and the core vestibular pathway (CVP) contributed to dysphagia. Moreover, a significant negative correlation was found between dysphagia severity and key DTT-derived metrics, such as lower fractional anisotropy (FA) and tract volume (TV), indicating that reduced FA and TV values are associated with more severe dysphagia symptoms. Conclusions: DTT provides valuable insights into the neural mechanisms underlying dysphagia after stroke. Identifying the affected tracts can help diagnose dysphagia more accurately and develop targeted rehabilitation strategies.

脑卒中后吞咽困难原因的扩散张量示踪研究：系统综述。

背景/目的：本系统综述旨在通过弥散张量神经束造影（DTT）研究脑卒中后吞咽困难的原因。方法：本综述使用谷歌Scholar、PubMed和ScienceDirect等数据库。使用脑卒中、吞咽困难、弥散张量肌束造影相关关键词。选取并分析了7项研究。结果：分析发现，皮质球束（CBT）损伤是最常见的吞咽困难的原因。此外，一些研究表明，前庭脊髓束（VST）和核心前庭通路（CVP）的损伤是导致吞咽困难的原因。此外，吞咽困难的严重程度与dtt衍生的关键指标（如较低的分数各向异性（FA）和肠道容积（TV））之间存在显著的负相关，表明FA和TV值的降低与更严重的吞咽困难症状相关。结论：DTT为卒中后吞咽困难的神经机制提供了有价值的见解。识别受影响的胃肠道有助于更准确地诊断吞咽困难，并制定有针对性的康复策略。

期刊介绍： Brain Sciences (ISSN 2076-3425) is a peer-reviewed scientific journal that publishes original articles, critical reviews, research notes and short communications in the areas of cognitive neuroscience, developmental neuroscience, molecular and cellular neuroscience, neural engineering, neuroimaging, neurolinguistics, neuropathy, systems neuroscience, and theoretical and computational neuroscience. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Electronic files or software regarding the full details of the calculation and experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material.
