Dr. Andi Engel frequently is asked, “Is there a connection between hearing loss and dementia?” This is a common question from older patients and their loved ones. Recent research, including a large study from the University of Southern Denmark, reinforces this link. The study, involving over 573,000 people aged 50 and above, found that untreated hearing loss increases the risk of dementia by 20%, while using hearing aids can significantly reduce this risk. These findings highlight the importance of treating hearing loss as a potential strategy for preventing or delaying dementia, emphasizing the growing body of evidence supporting the connection between hearing health and cognitive decline.
