==Overview==
==[[Presbycusis overview|Overview]]==
'''Presbycusis''', or age-related [[hearing loss]], is the cumulative effect of aging on [[hearing]]. Also known as presbyacusis, it is defined as a progressive bilateral symmetrical age-related sensorineural hearing loss. The hearing loss is confined to higher frequencies.


==Presentation==
==[[Presbycusis historical perspective|Historical Perspective]]==
Hearing loss usually begins gradually after the age of sixty, and is usually found more often in men than women. This can be miscontributed to men having a greater [[noise health effects|exposure to environmental noise]]. However, exposure to environmental noise can lead to [[Noise-induced hearing loss]] (NIHL), a hearing issue that is separate from presbycusis. 


Over time, the detection of high-pitched sounds becomes more difficult and both ears tend to be affected.
==[[Presbycusis classification|Classification]]==


===Pathophysiology===
==[[Presbycusis pathophysiology|Pathophysiology]]==
Examples of microscopic changes seen in this condition are hair cell degeneration of the [[cochlea]] and giant stereociliary degeneration.


==Causes==
==[[Presbycusis causes|Causes]]==
Factors responsible for presbycusis:
* Hereditary: Features like early aging of the cochlea and susceptibility of the cochlea for drug insults are genetically determined.
* [[Atherosclerosis]]: May diminish vascularity of the cochlea, thereby reducing its oxygen supply.
* Dietary habits: Increased intake of fatty diet may accelerate atherosclerotic changes in old age.
* [[Diabetes]]: May cause vasculitis and endothelial proliferation in the blood vessels of the cochlea, thereby reducing its blood supply.
* Noise trauma: Exposure to loud noise on a continuing basis stresses the already hypoxic cochlea, hastening the presbycusis process.
* Smoking: Is postulated to accentuate atherosclerotic changes in blood vessels aggravating presbycusis.
* [[Hypertension]]: Causes potent vascular changes, like reduction in blood supply to the cochlea, thereby aggravating presbycusis.
* Ototoxic drugs: Ingestion of ototoxic drugs like aspirin may hasten the process of presbycusis.


==Cultural aspects==
==[[Presbycusis differential diagnosis|Differentiating Presbycusis from other Diseases]]==
Recently, this condition has led to the development of technologies to stop younger people from loitering near British stores ([[The Mosquito]]), and the development of a cell phone ringtone, [[Teen Buzz]], for students to use in school, that many older instructors are unable to hear. In [[September 2006]] this technique was used to make a dance track called 'Buzzin'. The track had two melodies, one that everyone could hear and one that only younger people could hear.
