大约25%的先天性感音神经性听力损失是由先天性巨细胞病毒（CMV）感染引起的，这也影响了更高的大脑功能。我们评估了先天性巨细胞病毒感染的聋儿人工耳蜗植入（CI）的结果，其中一些患有广泛性发育障碍（PDD），包括自闭症。在无PDD的病例中，术后CI辅助的语言发展与术前认知发展显著相关，但在PDD的病例中，其CI辅助的语言发展远低于其认知发展的预期。提示PDD语言发育迟缓的发生机制可能不同于其他高级脑功能障碍包括智力发育迟缓。

Approximately 25% of congenital sensorineural hearing loss is caused by congenital cytomegalovirus (CMV) infection, which also affects higher brain functions. We evaluated cochlear implant (CI) outcomes of deaf children with congenital CMV infection, some of which suffered from pervasive developmental disorders (PDD) including autistic disorder. Incases with out PDD, the postoperative CI- aided language development is significantly associated with their preoperative cognitive development,but incases with PDD, their CI- aided language development was much lower than those expected from their cognitive development. These data suggests that mechanism of language retardation in PDD might be d fferent from those in other higher brain dysfunctions including mental retardation.
