Harvard study finds: people with untreated hearing loss are at higher risk for this condition

A new discovery published by Dr. Howard E. LeWine, Chief Medical Editor at Harvard Health, reveals “[loss of hearing] can lead to social isolation and depression… and is also linked to loss of memory and thinking skills.”

These findings are incredibly important, given that 1 in 3 adults over the age of 65 have some degree of hearing loss. Left untreated, hearing continues to deteriorate and can put adults at greater risk of dementia and cognitive decline.

So how can people with hearing loss improve their chances at longevity and preserve their mental health? By treating it as soon as possible.

Over 540,000 wearers are reducing their risk of cognitive decline with this tiny hearing aid, which packs cutting-edge technology into a virtually invisible design.

Improving brain function with hearing aids

When the brain is working harder than usual to hear, things like memory, focus, and mood can suffer as a result. But a good pair of hearing aids can make it far easier to understand speech and free up the mind for all of the normal functions we've come to rely on.

Today, hundreds of thousands of Americans are turning to Horizon IX hearing aids, known for their incredible speech clarity and practically invisible design, making them nearly impossible for others to see when they're placed inside the ear
