By Rita Panoscha MD

Developmental language delays and language disorders are a relatively common developmental finding in preschool children. The author reviews current literature; studies indicate a persistence of language delays in a percentage of children.

Key Points

  • Developmental language disorders are not uncommon, and they have some long-term impacts on the lives of the individuals.
  • Clinicians need to rule out disorders such as hearing impairment, mental retardation, autism, and other neurologic disorders that can also lead to language delays.
  • No clear etiology has been found for developmental language disorders, but there is much interest in finding a gene or genes that affect language development.
