Hearing Loss Disorder: Symptoms and Causes

Anyone can experience hearing loss, including newborns. Although there are a number of factors that can circumvent this condition, a study conducted by the Hearing America Research Foundation found that about half of cases of hearing loss are caused by hereditary factors. In Australia, a similar study was conducted in patients aged 50 years and over who suffered from age-related hearing loss. It was found that most patients have family members with similar conditions. In addition, it is also found that this condition is more experienced women than men. Visit reviews factor to get info about hearing loss.

The use of clinical methods to diagnose hearing loss in newborns is not effective. Identification of this condition should be done by measuring the response of the baby’s clicking mechanism. Hearing loss in infants is categorized into two. If the baby loses his hearing after birth, then it is a congenital condition. If hearing loss occurs in the next stage of age, then it is a condition obtained. Genetic testing can help ensure that the patient’s condition is congenital. The two genes that are usually tested are GJB2 and GJB6. Other gene testing is also possible but depends on the case at hand.

Hearing loss associated with family history is due to genetic factors. In cases of sensorineural congenital deafness (CSD), the main cause is a change in the GJB2 gene. This type of hearing loss occurs before the baby develops speech. If not addressed immediately, may increase the likelihood of disruption of child speech development. In CSD, abnormalities can occur in any part of the auditory pathway, including the auditory nerve that sends a hearing signal to the hearing part of the brain. Abnormalities in the hearing of the brain are rare. If it happens, the sufferer may experience total deafness. Many infants diagnosed with CSD also have a congenital defect in facial features or other parts of the body, including internal organs. In adults, hearing loss is often related to age. However, as mentioned above, cases of age-related hearing loss are also attributable to congenital conditions. Hearing loss identified in patients under 40 years is referred to as the initial condition. About 50% of the initial condition, or also called pre-lingual hearing loss, is caused by genetic factors.

Hearing loss patients with a family history usually feature symptoms other than deafness. As described above, infants diagnosed with CSD usually present with other abnormalities as well. The disorder differs according to the type (syndrome) of hearing loss. Those who have been diagnosed with Usher syndrome usually experience progressive blindness. Meanwhile, those with Alport syndrome usually have kidney problems. Pendred syndrome is usually followed by an enlarged thyroid, and people with Stickler symptoms usually have abnormalities in their face, arthritis, and also vision problems.
