Abstract
Aim of the work
The aim of such essay study was to write a review about the effect of aging on the auditory system and its functional consequences. Specifically ; the study reviewed the effect of aging on the hearing in the elderly persons ; the effect of aging on the auditory evaluation tests ; management of hearing loss due to aging and recent research studies on the prevents or at least delay the effect of aging on the auditory system .
Summary
As we age we are increasingly likely to suffer from chronic conditions. Hearing impairment is among the top three such conditions along with arthritis and hypertension. It may have become a problem for the first time in old age or may have been acquired when younger or at birth.
There are a number of pathophysiological processes underlying age related changes in the auditory system. The effects of hearing loss can have consequences beyond the immediate loss of
Hearing, and may have profound effects on the functioning of the person.
While a deficit in hearing can be corrected to some degree by a hearing aid.
It is important that those dealing with elderly people are aware of all the issues involved in age related hearing loss.
Of all the changes in the senses that occur with age, deterioration in hearing is perhaps the most expected and indeed the most accepted decline.
Hearing serves a number of functions: it permits communication through speech, provides warning of potentially injurious events occurring outside the visual field.
The wider impact of hearing loss may therefore be profound, with consequences for the social, functional, and psychological wellbeing of the person.
Some of these problems can persist despite correction of the deficit with a hearing aid.This can result in the deaf person withdrawing from the everyday social interactions that are necessary for independent existence.
The auditory system acts to channel and transduce sound pressure waves into electrophysiological signals that can then be localised and interpreted by the higher cortical centres.
As hearing loss in the elderly may be atrributable to an underlying systemic or otological cause, any patient presenting with hearing loss needs to be thoroughly assessed before attributing their symptoms to age related changes.
