“It’s Just Hearing Loss.” — The 71% Dementia Risk No One Talks About
Every week I sit with families navigating dementia, and I hear the same thing: “It’s just hearing loss. He turns the TV up loud, but otherwise he’s fine.” Sometimes they’re right. But far too often, that “just hearing loss” is quietly robbing the brain of the stimulation it needs — and raising the risk of dementia by a staggering 71 percent.
My name is Dr. Erik Ilyayev. I’m a dementia care physician, a board member of the South Florida Alzheimer’s Association, and the CEO of MedBetter Health — one of the organizations selected by Medicare to participate in a groundbreaking new program designed to change how America cares for people living with dementia.
In this issue, I want to share the powerful connection I explain to every patient’s family: how untreated hearing loss accelerates cognitive decline, why the brain literally shrinks without it, and exactly what you can do right now to protect yourself or someone you love.
THE SCALE OF THE PROBLEM
The Number That Should Stop You in Your Tracks
A major study followed people for 15 years — not one year, not two — and found something remarkable: individuals with slight or greater hearing loss faced a 71 percent greater risk of developing dementia compared to those with normal hearing.
71 percent.
That’s not a small increase. That’s the difference between a brain that stays sharp and one that begins to atrophy because it’s not getting the rich sensory information it was built to process every single day.
THE BRAIN CONNECTION
Use It or Lose It — This Time It’s Your Mind
Think about it like this: your muscles don’t stay strong if you stop working out. The same principle applies to your brain.
Your ears are the gateway for massive amounts of data — conversations, sounds, the world around you. That information flows straight to your brain, keeping it active, processing, and healthy. When hearing loss blocks that input, the brain stops getting the workout it needs. Families often notice their loved one nodding along with a polite “mm-hmm… yeah, yeah” — smiling, but not actually hearing. The brain is starved of stimulation.
On a CAT scan, you can literally see the result in people with dementia: global cerebral atrophy. The brain physically shrinks. And when hearing loss is left untreated, that process can move faster — turning mild cognitive impairment into full dementia far more quickly.
WHAT YOU CAN DO TODAY
Hearing Aids Aren’t Just for “Old People”
If you or someone you love has hearing problems, the first step is simple: get it checked . No excuses.
If testing confirms hearing loss, the next step is usually hearing aids. And here’s where most people push back:
- “I don’t want to look old.”
- “I hate the way they make my ears feel.”
- “They make that whistling sound.”
I get it. But here’s the truth: modern hearing aids are incredibly discreet — many sit behind the ear with a nearly invisible thin tube. They work beautifully. And refusing them because of vanity or minor inconvenience is like refusing to exercise because you don’t like the way your sneakers look. The cost of doing nothing is far higher: a dramatically elevated risk of dementia.
Common questions
Quick answers from this issue
Is Hearing Loss Linked to Dementia?
“It’s Just Hearing Loss.” — The 71% Dementia Risk No One Talks About Every week I sit with families navigating dementia, and I hear the same thing: “It’s just hearing loss.

What should caregivers try first?
Write down what changed, when it started, and what was happening right before it. Reduce noise, slow the conversation down, and use one simple step at a time. Share the pattern with the family, care team, or clinician so everyone responds consistently.
When should families call a clinician?
Call a clinician promptly if the change is sudden, severe, unsafe, tied to a fall, fever, pain, dehydration, medication change, hallucinations, paranoia, or new confusion. Call emergency services for immediate danger.
