The familial transmission of speech and language disorders was investigated using a community sample of five year old children with speech and/or language impairment and a control group with normal language skills. The results indicated a significantly higher prevalence rate of language-related problems in families of speech and language impaired children than in normal language controls. Girls with speech/language impairments had more affected relatives than boys, suggesting that girls with this type of family history are at a greater risk of developing speech or language related problems. The pattern of transmission of speech and language disorders was also compared with published reports of the family histories of stuttering and reading disabilities, and with reports of cognitive and linguistic deficits among families of autistic individuals. The findings are discussed in relation to the theory of an underlying neurolinguistic diathesis common to these various disabilities.
利用一个社区样本，对有言语和/或语言障碍的五岁儿童以及语言技能正常的对照组进行了言语和语言障碍的家族遗传研究。结果表明，与语言正常的对照组相比，言语和语言受损儿童家庭中与语言相关问题的患病率明显更高。有言语/语言障碍的女孩比男孩有更多受影响的亲属，这表明有这种家族病史的女孩出现言语或语言相关问题的风险更大。还将言语和语言障碍的遗传模式与已发表的口吃和阅读障碍家族史报告以及自闭症个体家庭中的认知和语言缺陷报告进行了比较。结合这些不同残疾所共有的潜在神经语言学素质理论对研究结果进行了讨论。
