Mutism following brain trauma is quite common, is usually transient, and recovery of speech is essentially the rule. Lasting total absence of speech without aphasia is highly unusual. Three such patients, two of traumatic and one due to vascular origin showing buccofacial apraxia (BFA) and computerized tomography (CT) evidence of bilateral frontal lesions are reported. It is suggested that complete lasting mutism associated with BFA is a result of bihemispheric lesions affecting mainly the opercular part of the inferior frontal gyrus and immediate adjacent regions.
脑外伤后缄默症相当常见,通常是短暂性的,言语恢复基本上是常态。无失语症的持续性完全失语非常罕见。本文报告了三例这样的患者,其中两例由外伤引起,一例由血管源性病因导致,均表现为口面部失用症(BFA),且计算机断层扫描(CT)显示双侧额叶病变。有研究表明,与BFA相关的完全持续性缄默症是双侧半球病变的结果,主要影响额下回岛盖部及其紧邻区域。
