Dementia and Hearing Loss
They found a correlation with those who had hearing loss at the beginning of the study and later development of dementia with the severity of the loss increasing the risk of developing the disorder. Of course, Audiologists are aware that there are vast numbers of hearing impaired individuals who do not have dementia regardless as to the degree of their hearing impairment. As a consequence the study needs to be interpreted with considerable degree of caution.
It is known those with managed hearing health care live longer, happier and healthier lives than those who do not. This is thought to be related to the social isolation that hearing loss can cause from which a subset will go on to develop depression with its associated co morbidities.
Those with early signs of hearing loss are well advised to have their hearing examined by an Audiologist and to consider amplification if their situation is indicative of a benefit. Previous studies have suggested some improvement in lucidity in the ear phases of hearing loss when the individual is aided (Anand and Court).
