Hearing Loss: What the Evidence Actually Says
It is among the largest modifiable dementia risk factors, and people wait years on average before doing anything about it.
Key takeaways
- Associated with: raised dementia risk, social isolation and low mood
- Hearing aids: recommended, and associated with better outcomes
- Most useful single change: Get a hearing test rather than adapting around the loss.
- Commonest mistake: Delaying assessment, which is the usual pattern.
- See a doctor if any of the signs under "When to speak to a doctor" below apply to you.
What it is
Reduced hearing, most commonly age-related or noise-induced. It sits within Hearing Health. The figures come from the bodies named at the foot of this page.
The numbers, in one place
| Measure | Figure |

| Average delay before seeking help | several years |
What helps
The advice below comes straight from the guidance cited at the foot of this page.

What to avoid
What to steer clear of, and why it catches people out.

When to speak to a doctor
Seek same-day medical assessment for sudden hearing loss in one or both ears — sudden sensorineural hearing loss is treatable but the window is days. Also seek urgent advice for hearing loss with severe ear pain, discharge, dizziness, facial weakness, or after a head injury.

How this page was put together
Every figure, recommendation and warning above is taken from the guidance named in Where this comes from. Nothing on this page is inferred, summarised or generalised beyond what those bodies publish: where they give a number, it is their number, and where they are silent, so are we. Pages are rebuilt whenever the underlying record changes. Sign-off by a named clinician, where it has happened, is shown at the top of the page along with the date.
