以往的文献将纯构者障碍归为腔隙综合征的一种类型,但由于对纯构音障碍综合征详细的临床表现、CT 扫描和病理学资料认识不清楚,故对以往的分类尚存在疑问。作者认为更有理由将纯构音障碍定义为由中风所引起的无其它明显神经症状和异常体征的构音障碍突然发病。本研究阐明了纯构音障碍的临床表现,并通过 CT 和磁共振成象(MRI)检查明确其损害的解剖部位。 In the past, pure structure disorder was classified as a type of lacunar syndrome. However, due to the detailed clinical manifestations of pure dysarthria syndrome and the unclear understanding of CT scan and pathology data, doubt. The authors consider it more reasonable to define pure dysarthria as a sudden onset of dysarthria without other obvious neurological symptoms and abnormal signs caused by stroke. This study elucidated the clinical presentation of pure dysarthria and identified its damaged anatomical site by CT and magnetic resonance imaging (MRI).
