A recent study has indicated that individuals with untreated hearing loss may be more at risk of dementia when compared to those without hearing loss. The study, published in The Lancet Public Health journal on April 13, is the largest of its kind, comprising 437,704 individuals, and is the most compelling evidence to date of this connection. However, there is some hope. The findings also suggest that early detection of hearing loss and treatment with hearing aids can eliminate this increased risk to improve longevity.
