The daughter who called me had already made up her mind before she said hello. "I think it's starting." Her mother is 81, lives in Mar Vista, and had spent the last three Sunday dinners smiling at the wrong moments. Someone would ask about her garden and she'd answer about the neighbor's dog. Somebody would tell a joke and she'd laugh a half-second after everyone else, watching their faces to time it. "She's not tracking anymore," the daughter said. "She just nods."
I asked one question: Is she like that on the phone?
Long pause. "No. On the phone she's completely herself."
That is not what early dementia looks like. That is what a loud room and a bad ear look like.
I'm Patrick. I run CarePali, a non-medical in-home daily-living care practice serving West LA and coastal Ventura, and I'm a nursing student. This particular mix-up — hearing loss read as cognitive decline — is the one I see families make most often, and it's the one that costs the most, because the real thing underneath it is both fixable and genuinely dangerous if you leave it alone.
Why the confusion is so easy to make
Hearing loss in older adults almost never announces itself. It doesn't arrive as silence. It arrives as selective silence: high-frequency consonants go first. The vowels still come through, so speech doesn't disappear, it just goes mushy. "Fifty" and "sixty" become the same word. "Did you take your pills?" and "Did you talk to Bill?" become the same question.
Now put that in a Sunday dinner: six people, hard floors, a TV on somewhere, dishes clattering. Your parent is doing an enormous amount of cognitive work just to reconstruct sentences from fragments. They get about 70 percent of the words and guess the rest. Sometimes the guess is wrong. So they answer about the dog.
And here's the part families almost never see: it is exhausting, and it is embarrassing. So your parent develops strategies. They nod. They laugh on the delay. They give short generic answers that can't be wrong — "Oh, fine." "Not much." They stop starting conversations. They go quiet at the far end of the table.
From the outside, that reads as withdrawal, apathy, and confusion. That is a very reasonable list of things to be scared of. It's also the exact behavioral signature of someone who simply can't hear in that room.
How common this actually is
According to the National Institute on Deafness and Other Communication Disorders, roughly one in three adults aged 65 to 74 has hearing loss, and that rises to about half of adults over 75. Among adults 70 and older who could benefit from a hearing aid, fewer than one in three has ever used one.
Sit with that ratio for a second. This is not a rare condition being missed. It's the single most common unaddressed sensory problem in the aging population, and the default response is to do nothing about it for a decade.
The part that isn't just a quality-of-life issue
For a long time hearing loss was filed under "inconvenient but harmless." That filing is out of date.
Work out of Johns Hopkins published in Archives of Neurology in 2011, following adults over time, found that the risk of developing dementia rose with the severity of hearing loss — roughly double with mild loss, triple with moderate, and about five times with severe loss, compared with normal hearing. Since then, the Lancet Commission on dementia prevention has repeatedly listed hearing loss among the largest modifiable risk factors it tracks. Its 2024 update identified 14 modifiable factors that together are associated with something on the order of 45 percent of dementia cases worldwide, with hearing loss carrying one of the heavier individual shares.
Two honest caveats, because I'd rather you have the real picture than a scary one.
First, association is not the same as cause. Some of the link may run the other way, or share a common cause. Researchers generally point to a few plausible mechanisms — the constant extra cognitive effort of decoding degraded speech, the accelerated social isolation that follows, and possibly changes in the brain regions that stop getting normal auditory input.
Second, and this is the one you should know before anyone sells you a miracle: the largest randomized trial we have, ACHIEVE, published in The Lancet in 2023, followed roughly 977 adults aged 70 to 84 for three years. Across the whole group, hearing intervention did not significantly slow cognitive decline compared with a control program. But in a prespecified subgroup already at higher risk for decline, the hearing intervention slowed the rate of cognitive change by about 48 percent over those three years.
So the fair summary is this: treating hearing loss is not a proven dementia cure, and anyone who tells you it is has gotten ahead of the evidence. But for older adults already carrying risk, the best trial we have suggests it may meaningfully matter — and everything else it does for a person's life is not in dispute at all.
The two-week test before you assume the worst
You do not need a specialist to tell the difference between "can't hear" and "can't remember." You need two weeks of paying attention to the pattern. Cognitive decline is context-independent. Hearing loss is exquisitely context-dependent.
- Phone versus dinner table. If they're sharp one-on-one on the phone, with the receiver against one ear and no background noise, and lost at a crowded table — that's acoustics, not memory.
- Quiet room, face to face. Sit knee to knee in a quiet room with no TV. Ask the same kind of question that went sideways at dinner. Watch what happens.
- Do they watch your mouth? Most people with progressive hearing loss start lip-reading without ever knowing they started. If they turn to face you before you speak, or lean their better ear in, note it.
- TV volume. Is everyone else in the house complaining about the volume? Is the closed-captioning suddenly on?
- Do they ask you to repeat, or do they just agree? The switch from "what?" to reflexive agreement is the tell that they've stopped fighting it.
- Does it get worse when they're tired? Listening effort has a fuel tank. By evening it's empty, and comprehension falls off. That is also, confusingly, when sundowning shows up — so this one is worth mentioning to the doctor either way.
If the pattern is "fine when quiet, lost when noisy," you are almost certainly looking at hearing. If they're equally lost in a silent room at 10 a.m., that's a different conversation — and a real one to have with their physician, not with the internet.
What to actually do about it
In order, from easiest to hardest.
- Rule out earwax first. Cerumen impaction is common in older adults, more common in hearing-aid wearers, and it can produce a real, measurable drop in hearing that reverses completely once it's cleared. Have a clinician look. Do not go in after it at home with a cotton swab or an ear candle — that's how eardrums and canals get hurt.
- Review the medication list. Some drugs are ototoxic, and some cause tinnitus that masks speech. Their prescriber and pharmacist can flag it. This is worth doing anyway if nobody has looked at the full list in a year.
- Get an audiologic evaluation. An audiogram takes under an hour and gives you an actual answer instead of a family debate. Ask their primary care physician for a referral.
- Know what Medicare does and doesn't do. Original Medicare does not cover routine hearing exams or hearing aids. It may cover a diagnostic hearing exam when a doctor orders it to evaluate a medical problem. Many Medicare Advantage plans include some hearing benefit — check the specific plan, not the brochure. Since October 2022, the FDA has also allowed over-the-counter hearing aids to be sold directly to adults with perceived mild-to-moderate hearing loss, which changed the price floor substantially. OTC is not right for everyone, and it is not a substitute for finding out what's actually wrong first.
- Fix the room while you wait. This one is free and works tonight. Turn the TV off during meals, not down. Put a tablecloth and a rug in the room where you talk — hard surfaces are the enemy. Sit on their better side. Face them. Get their attention before you start the sentence rather than three words in. And when they miss something, rephrase it instead of repeating it louder; volume makes distorted consonants louder, not clearer.
Expect them to say no
They will probably resist. Hearing aids still carry a stigma that eyeglasses shed generations ago — for a lot of people of this generation, a hearing aid is a public announcement of being old in a way that bifocals never were. Arguing with that doesn't work.
What tends to work better is making it about what they're missing rather than what's wrong with them. Not "you can't hear anymore." Instead: the grandkids at the far end of the table, the punchline they had to fake, the sermon, the phone call with the sister in Manila. And then go with them to the appointment. The failure point in this whole process is rarely the audiologist — it's the six months of nobody making the call.
Where we fit
CarePali is non-medical in-home daily-living care. We don't test hearing and we don't diagnose anything. What we do is spend enough consistent hours in the home to notice the pattern — that your mother is sharp one-on-one and lost in a group, that the TV crept up again, that she stopped calling her friend on Thursdays — and to tell you plainly what we're seeing so you can take it to the right clinician. We also make the daily routine work in the meantime: getting to the appointment, keeping the room set up so conversation is possible, keeping the person connected while the medical side gets sorted.
If what you're actually worried about is memory, our dementia care page walks through what that support looks like. If you want to see the full range of what we cover, that's on our services page — plans start at $1,700 a month. And if you want a person to talk to instead of a form to fill out, start here, or just call us at (310) 818-3217.
Before you conclude that your parent is slipping away, check whether they can hear you. It is the cheapest test in this entire field, it takes two weeks of attention, and in my experience roughly half the families who run it come back with a very different problem than the one they were afraid of.
The other half find out early. That matters too.
