Prelingual deafness
Prelingual deafness
Prelingual deafness (/priːˈlɪŋɡwəl ˈdɛfnəs/) is a hearing impairment that is present before a child learns to speak and understand language. The term is derived from the Latin words 'pre' meaning 'before' and 'lingua' meaning 'tongue' or 'language'.
Causes
Prelingual deafness can be caused by a variety of factors, including genetic disorders, prenatal exposure to disease or drugs, premature birth, and birth complications. Some genetic disorders that can cause prelingual deafness include Usher syndrome, Pendred syndrome, and Waardenburg syndrome.
Diagnosis
Diagnosis of prelingual deafness is typically made through hearing tests that are performed in the first few days or weeks of life. These tests can include otoacoustic emissions testing and auditory brainstem response testing.
Treatment
Treatment for prelingual deafness can include hearing aids, cochlear implants, and speech therapy. Early intervention is crucial to help the child develop language skills.
