That "Memory Problem" Might Just Be Earwax. Here's How to Tell
Here's a number that should make you pause before you assume the worst about a parent's fading memory: up to 65% of adults over 65 have impacted earwax, according to research on cerumen management in older adults. That's not a rounding error. That's roughly two out of every three seniors walking around with a physical blockage in their ear canal that can look, on the outside, exactly like cognitive decline.

I've already written about why hearing loss is the single biggest modifiable dementia risk factor, and how most people wait nine years before doing anything about it. This is the sequel nobody asks for: sometimes what looks like hearing loss — or even dementia — isn't damage at all. It's wax. And it's fixable in one visit.
The Wax Buildup Nobody Warns You About After 60
Earwax impaction isn't just a kids'-and-swimmers problem. A 2024 analysis in Laryngoscope Investigative Otolaryngology found cerumen impaction prevalence of 18.6% in the general population age 12 and up — but 32.4% in adults 70 and older. That's nearly double.
Why does this happen more as we age? A few physical changes stack up:
- The ear canal narrows and its shape changes with age
- Hair growth inside the canal increases
- The skin's natural self-cleaning migration slows down
- Conditions common in older adults — diabetes, arthritis, neurological disorders — interfere with normal wax clearance
Add hearing aids into the mix, which many seniors now wear because of exactly the hearing loss risks I covered before, and you've got another mechanical reason wax gets pushed deeper instead of clearing out on its own.
Why It Gets Mistaken for Dementia, Not Just Deafness
This is the part that should genuinely surprise you. Cerumen impaction can cause measurable, reversible cognitive impairment — not just muffled hearing. A small but notable 2014 Japanese study found real improvements in both hearing and cognitive test performance in elderly patients with memory concerns after their impacted wax was simply removed.
Think about why: when you can't hear well, you stop following conversations. You nod along instead of responding. You withdraw from group settings because straining to hear is exhausting. Watch that from the outside for a few months and it looks a lot like someone "slipping." Clinicians have documented this exact confusion for decades — a 1995 case series in the medical literature was already titled, plainly, "Cerumen impaction in the elderly."
The Blind Spot: People With Dementia Don't Complain About It
Here's the catch that makes this dangerous rather than just interesting. People with existing memory issues often don't report the wax buildup themselves — they don't connect the dots, or they've lost the words to describe it. Clinical guidance specifically flags this: older adults with possible dementia, or anyone who can't clearly communicate symptoms, need proactive ear checks rather than waiting for a complaint.
That means if you're a caregiver, the burden is on you to ask for the check — not wait for your parent to mention their ears feel "full" or "clogged." A sudden increase in confusion, a person who suddenly seems to be tuning out more, or hearing aids that "stopped working" are all reasons to ask for a cerumen check before assuming anything more serious.
What an Actual Ear Check Looks Like
This isn't complicated or invasive. A primary care visit or an audiologist appointment can confirm impaction with a simple otoscope look — the same tool used for a standard ear exam. If wax is impacted, removal options include:
- Cerumenolytic drops (softening agents) used at home for several days
- Irrigation with warm water, done in-office
- Manual removal with a curette, done by a clinician
None of these require anesthesia or a specialist referral in most cases — a family doctor can usually handle it in one visit. What you should not do is reach for a cotton swab. Swabs are the single biggest cause of wax getting pushed deeper into the canal rather than out of it, which is part of why impaction rates are so high in the first place.
Where This Fits With Everything Else Going On After 60
This is one piece of a bigger pattern worth paying attention to: small, reversible things get misread as irreversible decline. It's the same reasoning behind checking B12 levels before assuming memory changes are dementia — a cheap, simple test can rule out something fixable before anyone commits to a scarier diagnosis. Wax removal costs less, takes less time, and carries less risk than almost any other intervention on this list, yet it rarely makes anyone's checklist.
What to Do This Week
If you or someone you care for has noticed hearing that seems worse than usual, TV volume creeping up, or "checked out" behavior in conversations, book a basic ear exam before anything else. Ask specifically: "Can you check for earwax impaction?" It takes minutes, costs far less than a hearing aid adjustment, and there's a real chance it's the entire explanation.
