Early diagnosis, coupled with special education programs can really help a child to successfully develop language skills. Let’s see some of the causes and symptoms of hearing loss in children.

Causes for Hearing Loss in Children

Hearing loss in children can be congenital and acquired in nature. Congenital reasons are those present during birth and acquired reasons are those gained after birth.

Nearly fifty-percent of all congenital hearing loss in children is caused due to genetic factors. In this, either of the parents has a dominant hearing loss gene and passes it to the child, implying 50% probability. If either of the parents has recessive hearing loss gene, there is a 25% probability for the child. Other factors for congenital sensorineural hearing loss range from prenatal infections from illnesses or toxins consumed by the pregnant mother. The hearing loss could range from mild to severe. Maternal diabetes, lack of oxygen, Rh factor complication, herpes simplex virus, rubella and premature birth are some other congenital reasons.

In acquired hearing loss in children, we have causes like chicken pox, meningitis, measles, influenza, mumps, head injuries, noise exposure, encephalitis, ear infections and consumption of ototoxic drugs. The acquired conditions are the result of an injury or disease ‘acquired’ after birth.
