Deaf-mutism

Hearing deficiency combined with impaired speech. If a child is born completely deaf it will not learn to speak of its own accord. Shortly after birth a child begins to imitate the sounds its parents make; hearing other people speak is essential for speech development. Congenital deafness often occurs within the same family. Hearing can also be damaged during pregnancy, by an illness such as German measles in the mother, or by the use of certain medicines. Sometimes damage is perinatal, caused by oxygen deficiency or severe jaundice in the infant, leading to brain damage (kernicterus). Some cases of congenital deafness are inexplicable. If a five-month-old child does not react to noise it should be examined by a doctor. Sometimes deafness can occur in childhood, as a result of meningitis or fracture of the base of the skull. Speech development in a deaf child is dependent on the degree of hearing loss and the age at which it occurs. In severe cases the chances of speech development are slight; in less severe cases development will be slowed down. If deafness occurs after the age of eight speech is well enough established for the child not to lose it. There are various methods of developing speech in some way and/or learning lip reading and sign language.
