The Hearing Loss That Everyone Mistakes for Something Else

It starts as a small thing on the weekly call. Your father answers a beat too late. Your mother says "haan, haan" to a question she clearly did not catch. She has quietly stopped joining the noisy family group call, says it is "too much." At the last visit she seemed to have pulled inward, quieter at the dinner table, no longer the one steering the conversation. From a distance, every one of these reads as something ominous: her memory, her mood, "getting old." But the most likely explanation is also the most ordinary, and almost nobody checks it first. She cannot hear clearly anymore, and she has learned to hide it.

Age-related hearing loss is a master of disguise. It looks like early dementia, because a parent who mishears a question and answers the wrong thing seems confused. It looks like stubbornness, or "selective hearing," because they catch you fine in a quiet room but seem to tune out at a crowded lunch. It looks like depression, because the person who can no longer follow the temple bhajan, the rummy game, or the grandchildren talking over each other simply stops going, and folds inward. Families misread all of it. So do busy doctors, who see a parent for ten minutes in a silent consulting room and never notice. Meanwhile the real thing goes untreated for years, wearing every label except its own.

This is not a rare problem you can assume away. Indian studies put some degree of hearing loss in more than half of people over sixty, and closer to two in three past seventy; the elderly carry the overwhelming majority of the country's disabling hearing loss. And yet the average person waits the better part of a decade before doing anything about it. The reason is rarely cost or access. It is denial and stigma. In India a hearing aid still reads as a public admission of being old and infirm, something to be hidden away, while spectacles are worn without a second thought. So parents cope. They turn the television up, nod along, ask you to repeat "just once more," and slowly build an entire life around not quite hearing it.

Here is the part that should change how seriously you take a misheard question. In 2024 the Lancet Commission on dementia named hearing loss the single largest modifiable risk factor for dementia, ahead of smoking, ahead of inactivity. The mechanism is unsettlingly simple: a brain starved of sound has less to work with, strains harder to fill the gaps, and pulls back from the social contact that keeps it sharp. Untreated hearing loss is also one of the straightest roads to isolation and depression in older people. And so the cruelty completes a loop: hearing loss looks like cognitive decline, gets mistaken for it, goes untreated for years, and then genuinely raises the risk of the very thing everyone feared in the first place.

And here, at last, is the good news, which is the real reason for this letter. Of all the things that worry you about an aging parent, this is among the most fixable. A hearing test takes about twenty minutes and costs very little. Modern hearing aids are small, discreet, and nothing like the whistling beige devices your grandparents refused to wear. Treating hearing loss is one of the very few levers we have that measurably protects the aging brain, lifts mood, and pulls a parent back into the middle of the room. The hard part was never the treatment. It is noticing, past all the wrong labels, that hearing is what needed treating at all.
