Cognitive and Behavioral Functioning in Hearing-Impaired Children with and without Language Delay

Abstract

Poor language development in patients with sensorineural hearing loss (SNHL) may be related to an auditory deficit and/or other neurologic condition that influences the ability to communicate. A retrospective chart review of children (mean age = 4.0 years) with congenital, bilateral SNHL was performed to assess for linguistic and nonlinguistic neurodevelopmental differences between those who were language-impaired (LI) versus non-language-impaired (NLI). Language, neurodevelopmental functioning, and behavior were assessed. Twenty-two patients were identified: 12 were LI and 10 were NLI. Average pure-tone thresholds and nonverbal intelligence were not different between the language groups, but the LI group demonstrated significantly lower median overall adaptive skills, personal living skills, and motor skills. Behavioral dysregulation was significantly higher in the LI versus NLI group (58% vs 10%; P = .031), although the median neurodevelopmental scores did not differ significantly. These findings introduce the possibility that nonlinguistic processing deficit(s) may be confounding the ability to develop language.
