Causes of Speech Retardation of Children With Normal Hearing / 听力学及言语疾病杂志

ABSTRACT

Thirty-one children suffered from speech retardation were found to have normal hearing level through ABR and/or acoustic immittance tests. Some of them were further checked by psychiatrists and pediatricians. The results demonstrate that among reasons for speech retardation in children,autism and mental retardation are important factors that can not be ignored. A-mong children with unclear diagnosis .some harmful factors were found on themselves and in surroundings. We emphasize that for children with speech retardation,not only hearing disorders,but also other factors should be considered.
