Brain And Hearing
We hear with our Brain not our Ears! Your ear receives information (sounds) and transfers them to the hearing branch (cranial nerve VIII) and then to the Auditory Cortex of your brain. The Auditory Cortex plays a critical role in speech/language comprehension and memory. Early stages of Dementia/Alzheimer's disease have been linked to reduced function of the Auditory Cortex. People with untreated hearing loss experience 30-40% faster decline in cognitive abilities compared to peers without hearing loss. Adults 50 years and older with untreated hearing loss are more likely to develop problems thinking and remembering than adults with normal hearing. If you or your family/friends show signs of hearing or memory loss, encourage them to have their hearing tested!
