The link between hearing loss and cognitive decline

In Canada, 38% of adults between the age of 20 and 79 years old suffer from hearing loss, and many never receive treatment. Furthermore, scientists have found that hearing loss often precedes diagnoses of age-related dementia by 5 to 10 years, suggesting that difficulty in hearing may contribute to cognitive decline – an interesting link that is supported by imaging studies showing functional and anatomical changes in the brains of older adults.
