DEFINITION

  • A communication disorder is a neurodevelopmental disorder characterized by impairments in sending, receiving, processing, or comprehending verbal, nonverbal, or graphic language, speech, and/or communication.
  • Communication disorders may be developmental or acquired (secondary to trauma or neurological disorder).
  • Language is one of five major streams of development, within which developmental milestone acquisition occurs at a specific rate in an orderly and sequential manner[1].
  • See Table Language and Social Milestones for language and social milestones in a typically developing child.
    • Deviation from these milestones may signal the presence of a communication disorder
    • For further developmental information, please see the American Academy of Pediatrics’ Bright Futures (http://brightfutures.aap.org…) or the CDC’s Milestones (http://www.cdc.gov…)
