Presbycousis: Etymology, Meaning, and Origin

Etymology

• "Presby-" (Greek): old age
• "-cousis" (Greek): deafness

Meaning

Presbycousis is a type of hearing loss that occurs gradually as a person ages. It is the most common form of hearing loss, affecting around 30% of people over the age of 65.

Origin

Presbycousis is caused by changes in the structure and function of the inner ear as a person ages. These changes include:

• Loss of hair cells in the cochlea, the sensory organ of hearing
• Stiffening of the basilar membrane, the structure in the cochlea that vibrates in response to sound
• Changes in the nerve fibers that transmit sound signals from the cochlea to the brain

These changes result in a decreased ability to hear high-frequency sounds, particularly in noisy environments.

Symptoms

Symptoms of presbycousis include:

• Difficulty hearing high-pitched sounds, especially in noisy environments
• Muffled or distorted speech
• Tinnitus (ringing in the ears)
• Difficulty understanding conversations, especially in groups
• Sensitivity to loud noises

Treatment

There is no cure for presbycousis, but there are treatments that can help to improve hearing. These include:

• Hearing aids: Amplify sound to make it easier to hear
• Cochlear implants: Devices that bypass the damaged hair cells in the cochlea and stimulate the auditory nerve
• assistive listening devices, such as captioning and FM systems
• Strategies to improve listening conditions, such as reducing background noise
