  •  Congenital deafness is deafness that is presentat birth. Congenital Deafness is present inapproximately one out of every one or twothousand births. Congenital hearing loss can be caused by agenetic condition or deformity of the ear. Themost common form of congenital deafness isthrough heredity.
  • Congenital deafness is caused bythe abnormal development of theinner ear or of thevestibulocochlear nerve, whichtransmits electrical impulses fromthe inner ear to the brain. In abouthalf of all cases, the condition runsin families, suggesting that agenetic factor may be involved.
  • Causes of Congenital Deafness Certain infections, such as rubellaor cytomegalovirus (CMV), can also causecongenital deafness if they are transmittedfrom the mother to the fetus during theearly stages of development . The development of hearing may also beaffected if the mother takes certain drugsduring pregnancy, particularly some typesof antibiotic.
  • Being mute is often associatedwith deafness as people whohave been unable to hear frombirth may not be able toarticulate words correctly.
  •  There is no cure for congenital deafness, butany hearing that a child has can bemaximized with a hearing aid. Education and support for the child, ishighly necessary. It is important to ensure that a child cancommunicate. He or she may be taught signlanguage and lip-reading. Some children areable to learn to speak.
  •  Sign Language uses visually transmitted sign patterns(manual communication, body language) to conveymeaning—simultaneously combining hand shapes,orientation and movement of the hands, arms or body,and facial expressions to fluidly express a speakersthoughts. Wherever communities of deaf people exist, signlanguages develop. Their complex spatial grammarsare markedly different from the grammars of spokenlanguages.
  • Learning toCommunicate, HavingSocial GroupMaintaining Self-Esteemand Respect for others
