Hearing loss – age related; Presbycusis
Definition of Age-related hearing loss
Age-related hearing loss, or presbycusis, is the slow loss of hearing that occurs as people get older.
Causes, incidence, and risk factors
Tiny hairs inside your ear help you hear. They pick up sound waves and change them into the nerve signals that the brain interprets as sound. Hearing loss occurs when the tiny hairs inside the ear are damaged or die. The hair cells do not regrow, so most hearing loss is permanent.
The loss of hearing occurs slowly over time. It is most difficult to hear high-frequency sounds, such as someone talking. As hearing gets worse, it may become difficult to hear sounds at lower pitches.
Signs and tests
A complete physical exam is performed to rule out medical conditions that can cause hearing loss. The health care provider will use an instrument called an otoscope to look in your ears. Sometimes, wax can block the ear canals and cause hearing loss.
There is no known cure for age-related hearing loss. Treatment is focused on improving your everyday function. The following may be helpful:
Age-related hearing loss is progressive, which means it slowly gets worse. The hearing loss is permanent.
