Researchers have studied evidence on hearing loss in older people and have found that 25 to 40 percent of those aged 60 and older are hearing impaired. Doctors while examining older patients must check for hearing loss, for this may be easily remedied. The condition can lead to depression, social isolation and decrease in functional ability. There are several reliable tests to detect hearing loss at an early stage. While most of hearing loss appears to be sensorineural 'nerve deafness' arising from damage to the tiny hair cells in the inner ear, hearing aids do improve outcomes for this kind of deafness. The other causes of hearing loss include ear wax impaction and chronic otitis media (fluid in the middle ear). However these conditions could be cured by surgery. It's important that the physician checks his or her older patients regularly for hearing loss.
