How Sensory Loss May Increase the Risk of Dementia in Older Adults

As we age, many of us begin to experience sensory changes—such as vision problems, hearing loss, or a diminished sense of touch, smell, or taste. While these changes can feel like a normal part of aging, growing research shows a clear link between sensory decline and increased risk of dementia. At LiveWell Care Management, we believe that proactive attention to sensory health is a vital part of aging well and protecting cognitive function.

What the Research Shows: Sensory Loss and Cognitive Decline

Multiple recent studies have confirmed that age-related sensory loss—especially untreated hearing or vision problems—may significantly raise the risk of developing dementia:

A 2019 study from the University of Michigan found that older adults with hearing loss who did not use hearing aids were nearly 20% more likely to develop dementia.

Research published in JAMA Ophthalmology linked vision loss to faster cognitive decline, emphasizing the importance of early eye care and treatment.

At the Alzheimer’s Association International Conference, studies showed that even mild loss of hearing, sight, or smell could increase dementia risk—and that combined sensory loss raises the risk even more.

These studies reinforce the importance of early screenings, diagnosis, and treatment of sensory changes in older adults.

Why Sensory Loss Impacts Brain Health

Sensory decline doesn’t just affect how we see or hear—it can lead to a cascade of challenges that impact brain function, including:

• Reduced cognitive stimulation, which limits the brain’s ability to form new neural connections
• Social isolation and loneliness, which are proven risk factors for dementia
• Increased difficulty managing chronic conditions like diabetes and heart disease
• Greater mental effort to process information, creating extra cognitive strain (also called "cognitive load")
• Additionally, dementia itself can affect how the brain processes sensory input, even if eyesight or hearing is physically intact.

How to Protect Sensory Health and Lower Dementia Risk

At LiveWell, we help families incorporate sensory health into their overall care planning. Here’s how you can take action:

1. Schedule Regular Screenings

Encourage annual hearing and vision checkups, and talk to your doctor about any changes in taste, smell, or touch. Early detection allows for earlier treatment—and better outcomes.

2. Address Vision Problems Early

• Keep prescriptions for glasses current
• Treat conditions like cataracts, glaucoma, or macular degeneration promptly
• Work with vision rehabilitation specialists when needed to maximize remaining vision

3. Treat Hearing Loss Promptly

• Explore modern hearing aid options—they’re more discreet and effective than ever
• Address barriers like cost or stigma with the support of an audiologist
• Begin treatment early to help the brain stay active in processing sound

4. Promote Brain-Healthy Habits

Protecting sensory function is only one part of maintaining brain health. We also recommend:

• Eating a nutritious, anti-inflammatory diet
• Staying physically and social active
• Managing chronic health conditions
• Getting adequate sleep and reducing stress
