Negative Consequences of Uncorrected Hearing Loss
In the review, the focus is on hearing loss and the possibilities of overcoming at least some of its effects by means of hearing aids.
The results showed that hearing-impaired people who did not use hearing aids more often stated that they felt sad or depressed, were worried, showed paranoid tendencies, took part in less social activity, and experienced more emotional turmoil.
Although the groups were small, the results showed that even a slight hearing loss gives rise to increased problems of speech recognition in noise and reduced feeling of wellbeing.
In addition to hearing thresholds, visual acuity was tested, and cognitive functions were assessed by a series of tests.
The results showed that sensory function was a good predictor of age-related differences in cognitive function, and that the relationship between sensory function and cognitive function increased with age.
The authors conclude that the mechanisms behind age-related changes in sensory function are also behind age-related changes in cognitive function.
The authors concluded that their results support the hypothesis of hearing loss contributing to reduced cognitive function in the elderly.
A common finding among the reports reviewed above is a significant correlation between hearing loss and reduced cognitive function.
If the hearing loss is a cause of cognitive decline, this is a very strong argument for early detection of hearing loss and fitting of hearing aids.
