Abstract

|
Age-related hearing loss (ARHL), known as presbycusis, is the term encompasses all conditions that lead to hearing loss in elderly people. ARHL is characterized by gradual deterioration of auditory sensitivity, loss of the auditory sensory cells, and central processing functions. ARHL is thought to result from age-related degeneration of the cochlea with the cumulative effects of extrinsic damage. If left untreated, ARHL significantly decreases the autonomy of affected older persons by increasing their reliance on community or family support. And a loss of hearing can not only lead sufferers to reduce the quality of life but also affect the healthy people around. For most hearing-impaired people, the hearing loss has physical, social and psychological consequences including isolation, depression and dementia. ARHL is becoming a severe social and health problem in the developed countries including the Republic of Korea, therefore, optimal management not only requires early recognition and proper rehabilitation, but it also should be patient-centered and individualized.
