What is Congenital deafness?

Loss of hearing present at birth or loss that may develop later but is due to genetic causes or other influences that affected the fetus while it was in utero (in the womb).

A child with a congenital hearing loss should begin receiving intervention before 6 months of age. Studies suggest that children who receive early interventions are better able to develop communication skills (using spoken or sign language). Once a child is diagnosed, doctors or the audiologists can counsel the family and provide options for intervention. In the United States of America, because of a Federal law (the Individuals with Disabilities Education Act), children with a hearing loss between birth and 3 years of age have the right to receive interdisciplinary assessment and early intervention services at little or no cost. After age 3, early intervention and special education programs are provided through the public school system.
