Sensory: High-frequency hearing deficit caused by loss of hair cells. There are four pathological phenotypes of presbycusis: Presbycusis is sensorineural hearing loss, in which cochlear hair cells and, to a lesser extent, the spiral ganglion cells in the vestibulocochlear nerve can be affected. 25. pathophysiology • Histologic changes associated with aging occur throughout the auditory system from the hair cells of the cochlea to the auditory cortex in temporal lobe of the brain • Elucidation of pathophysiology of presbycusis is still incomplete. Age-related hearing impairment (ARHI), also referred to as presbycusis, is the most common sensory impairment seen in the elderly.
Hearing loss is defined as one of three types: Conductive (involves outer or middle ear) Sensorineural (involves inner ear) Mixed (combination of the two) Metabolic presbycusis is the mainstay of presbycusis types. As our cochlea, the peripheral organ of hearing, ages, we tend to experience a decline in hearing and are at greater risk of cochlear sensory-neural cell degeneration and exacerbated age-related hearing impairments, e.g., gradual hearing loss, deterioration in . About 30-35 percent of adults age 65 and older have a hearing loss.

Also known as presbyacusis, it is defined as a progressive bilateral symmetrical age-related sensorineural hearing loss. In literal terms, presbycusis means "old hearing" or "elder hearing." It becomes noticeable around age 60 and progresses slowly; however, there is evidence that certain stressors can speed the rate of deterioration. Presbycusis is the most common form of hearing loss in the elderly, although it often goes unrecognized. Hearing is the sense that ages the least gracefully: because of their comparatively small number, the disappearance of hair cells and cochlear neurons over time cause an age-related hearing loss.
