Pre- Lingual Deafness
Pre-lingual deafness is hearing impairment that is sustained prior to the acquisition of language, which can occur as a result of a congenital condition or through hearing loss in early infancy. Pre-lingual deafness impairs an individual’s ability to acquire a spoken language.
Post- Lingual Deafness(Pediatric or Geriatric Hearing Loss)
Post-lingual deafness is hearing impairment that is sustained after the acquisition of language, which can occur as a result of disease, trauma or as a side-effect of a medicine. Typically, hearing loss is gradual and often detected by family and friends of affected individuals long before the patients themselves will acknowledge the disability. Common treatments include hearing aids and learning lip -reading. Post-lingual deafness is far more common than pre-lingual deafness.
