Hearing Loss - Symptom Evaluation - Causes, Diagnosis, Treatment, Health Tips, FAQs
Hearing loss is a common problem that could occur in childhood or often develops with age or is caused by repeated exposure to loud noises. Keep abreast on its causes and symptoms.

‘Researchers argue that the stria vascularis, a part of the cochlea in the ear, is a new target for treatments to help people with hearing loss.’
Many people gradually lose some of their hearing ability as they get older, and an estimated 2.4 billion individuals will have some form of hearing loss by 2050. Age-related hearing impairment is a top contributor to years lived with disability and is also a significant risk factor for dementia.
Genetics Behind Hearing Loss
The team studied genetic analyses previously carried out in centers around the world using samples from 723,266 people from 17 studies who had clinically diagnosed or self-reported hearing impairment. This meta-analysis is one of the largest conducted in hearing genetics to date. The researchers identified 48 genes linked to hearing loss, including 10 new variants newly linked to hearing.Further analysis looking at mouse genetics indicated that age-related hearing loss is due to changes in the stria vascularis which is necessary for hearing. The results provide targets for the basis of future research which could improve therapies against hearing loss.
Co-main author Frances Williams, professor at King’s College London, said: “Our findings identify 10 genes newly linked with hearing loss. This study points to genes we could target for screening purposes, drug development and even gene therapy in the future. This study provides a solid foundation for ultimately improving therapies against hearing loss.”
Hearing Loss in Young Children and Early Intervention
Early identification of hearing loss in infants and young children and treating hearing impairment can go a long way to integrate them into the society of talking people.

Anatomy of Ear and Hearing
Ear converts sound waves into electrical impulses that are transmitted to the temporal lobe of the brain through the auditory nerve. It consists of outer, inner and middle sections.

Quiz on Hearing Loss
A little difficulty in hearing is natural with the aging process but if the auditory damage occurs because of other reasons, it can be a cause for concern. Take this quiz to find out how much you know about hearing loss.
