目的探讨急性脑梗死后构音障碍与梗死部位的关系。方法研究78例突发构音障碍的脑梗死患者,经影像学证实均为单个梗死。结果引起构音障碍的脑梗死可位于初级皮层运动区、放射冠及半卵圆中心、内囊、脑干及小脑。结论引起构音障碍的小脑外梗死,大多影响锥体束。任何部位的小脑梗死均可引起构音障碍。 Objective To investigate the relationship between dysarthria and infarction after acute cerebral infarction. Methods 78 patients with sudden dysarthria of cerebral infarction were confirmed by imaging studies were a single infarction. Results Cerebral infarction caused by dysarthria may be located in the motor cortex of the primary cortex, the coronoid and the semio-oval center, the internal capsule, the brain stem and the cerebellum. Conclusion Cerebellar infarction, which causes dysarthria, mostly affects pyramidal tract. Cerebellar infarction in any area can cause dysarthria.
