The loss of hearing or balance problems can increase the rate of cognitive decline in older people with mild dementia. Recent studies show that, by reducing the risk factors such as hearing loss, smoking, depression, diabetes, hypertension and obesity, more than a third of dementia cases might theoretically be preventable. In this study, we present a novel strategy to delay the progression of age-related hearing loss using a mouse model. As a secondary outcome, the impact of delaying of hearing loss in these animals will be correlated with cognitive decline.
