As research continues in the area of untreated hearing loss more and more findings show that it is not worth it to wait to do something about hearing deficits. Current research is showing correlations between untreated hearing loss and dementia, depression, heart disease, and diabetes, as well as increased mortality.
A study published in the Archives of Neurology on February 14, 2011 found that hearing loss was associated with dementia (all causes). They noted that the greater the hearing loss the more at risk a person was for dementia. Additionally, they noted that for individuals in their study over the age of sixty, more than one-third of the subjects with risk of dementia had associated hearing loss. One reason that may support these findings would be the exhausting of cognitive reserves; in other words more brain power goes into straining to listen for comprehension of speech than other cognitive processes, like working memory.
