Cerebral reorganization during recovery after stroke has been investigated using functional imaging in patients with subcortical motor stroke. The functional correlates of recovery from anarthria, however, are yet unknown. A 48-year-old male patient recovering from complete anarthria after unilateral right-sided subcortical hemorrhagic stroke is described. The main outcome measures included clinical and neuroimaging data at three different time points (at the onset of symptoms, after 6 weeks and after 6 months). At 6 weeks, increased activations in the right and left frontal operculum were found and were followed by a trend towards normalization of the activation pattern at 6 months. These results suggest a role of anterior opercular regions in recovery from anarthria after subcortical stroke. Moreover, complete recovery is possible after such lesions.
脑卒后恢复过程中的大脑重组已在皮质下运动性卒中患者中通过功能影像学进行了研究。然而,失音症恢复的功能相关性尚不清楚。描述了一位 48 岁男性患者,在右侧皮质下出血性卒中后完全失音,正在恢复中。主要的测量指标包括三个不同时间点(症状发作时、6 周后和 6 个月后)的临床和神经影像学数据。在 6 周时,发现右侧和左侧额盖的激活增加,并且在 6 个月时激活模式有趋于正常的趋势。这些结果表明,在皮质下卒中后失音症的恢复中,前盖区域起作用。此外,在发生此类病变后完全恢复是可能的。
