Get Checked: Why Regular Hearing and Eye Tests Matter for Brain Health

When most people think about reducing the risk of dementia, they picture brain exercises, puzzles, or eating a healthy diet. While those things help, one often-overlooked factor is just as important: taking care of your hearing and vision. Regular hearing and eye tests are not only vital for daily quality of life, but research shows they also play a major role in brain health and dementia risk.

The Link Between Senses and the Brain

Hearing and vision are gateways to the world. When they decline, the brain receives less stimulation, and that can lead to changes in memory, focus, and problem-solving. Scientists have found that untreated hearing loss and poor vision are both linked to higher rates of cognitive decline. In fact, hearing loss has been identified as one of the most significant modifiable risk factors for dementia.

Why Hearing Tests Matter

When hearing fades, the brain has to work harder to process sounds, leaving less energy for memory and thinking. People with untreated hearing loss are also more likely to withdraw from conversations and social activities, which increases isolation—a known dementia risk factor.

The good news? Hearing aids and other treatments can reduce this risk. Studies suggest that people who use hearing aids may experience slower cognitive decline compared to those who don’t. Getting a simple hearing test every 1–2 years, especially after age 60, can make a huge difference.

Why Eye Tests Matter

Vision problems affect more than just sight—they can impact balance, independence, and brain stimulation. Cataracts, glaucoma, and macular degeneration can all make it harder to stay engaged in daily activities. When older adults struggle to see, they may read less, drive less, and avoid social events, all of which can reduce mental sharpness. Regular eye exams help detect problems early. Corrective lenses, surgery, or treatments can restore clarity, keep people active, and reduce dementia risk by keeping the brain engaged.

Barriers and Solutions

Many older Americans put off hearing and eye tests because of cost, inconvenience, or the belief that changes are “just part of aging.” But untreated issues don’t just affect the senses—they affect the brain. Medicare and many insurance plans cover certain screenings, and community health centers often provide affordable options. Family members can play a vital role in encouraging loved ones to schedule these appointments and offering support with transportation or reminders.

Practical Steps You Can Take

Schedule hearing and vision tests regularly, even if you don’t notice big changes.

• Use corrective aids—glasses, contacts, or hearing devices—as recommended.

• Stay socially active, even if hearing or vision challenges remain.

Protect your senses: avoid loud noise, wear sunglasses outdoors, and keep chronic conditions like diabetes under control.

Final Thought

Dementia prevention isn’t just about the brain—it’s about the whole body. By protecting your hearing and vision, you’re not only improving your quality of life today, but also lowering your risk of cognitive decline in the future. Regular checkups are a simple, powerful step toward healthy aging.

Don’t wait until problems get worse—get checked, stay connected, and keep your brain engaged for years to come.
