Presbycusis: hearing loss due to age

Presbycusis is hearing loss associated with aging. Hearing loss with aging is very common. About 25% of people between age 65 and 74 and 50% of people over age 75 have hearing problems. Beginning at approximately age 40, progressive inner ear hair cell loss begins. This may consist of degeneration of part of the inner ear that senses hearing (Organ of Corti), loss of the inner ear nerves, degeneration of the blood supply to the inner ear, or stiffening of the inner ear membranes. All of these problems can cause hearing loss. Presbycusis usually affects both ears equally, is usually slowly progressive, and is worse in the high frequencies or pitches. In addition, the ability to understand speech clearly (discrimination) also worsens with advancing age. This may also be accompanied by tinnitus (ringing or noise) in the ears. Examination of the ears is usually normal. Unfortunately no medication or surgery can restore the hearing, but a hearing aid is usually beneficial.
