How hearing loss in old age affects the brain

If your hearing deteriorates in old age, the risk of dementia and cognitive decline increases. So far, it hasn’t been clear why. A team of neuroscientists at Ruhr-Universität Bochum (RUB) in Germany examined what happens in the brain when hearing gradually deteriorates: key areas of the brain are reorganized, and this affects memory. The results are published online in the journal “Cerebral Cortex” dated 20 March 2020.
