hearing loss & cognitive decline
Research suggests
Research continues to show important connections between hearing health and overall well-being.
Studies from institutions such as Johns Hopkins Medicine have found that untreated hearing loss is associated with increased risk of cognitive decline, balance issues, and reduced physical stability in some individuals.
In long-term studies of older adults, mild hearing loss was associated with approximately double the risk of developing dementia, while moderate and severe hearing loss were linked with even higher risk levels.
These findings highlight the importance of identifying hearing changes early and maintaining clear communication throughout life.
What is the relationship between hearing and health?
Hearing plays an important role in how the brain processes information and interacts with the surrounding environment.
Research suggests that when hearing loss goes untreated, the brain must work harder to interpret speech and everyday sounds. Over time, this increased listening effort may contribute to mental fatigue and reduced cognitive efficiency.
Studies have also shown that individuals with untreated hearing loss are more likely to experience social withdrawal, as communication can become more difficult. Reduced social engagement is considered one of several factors associated with cognitive decline.
Hearing also contributes to environmental awareness and balance. Subtle sounds in our surroundings help the brain monitor movement and maintain stability, which may explain why hearing changes can sometimes be associated with balance or mobility challenges.
Understanding the Terminology
Social Isolation
Social interaction plays an important role in both emotional and cognitive well-being.
When hearing becomes more difficult, conversations can require greater effort. Over time, some individuals may begin to withdraw from social situations simply because communication becomes challenging.
Reduced social engagement can affect quality of life and has been identified in research as one factor associated with cognitive decline.
Maintaining clear communication and staying socially connected are important components of overall brain health.
Dementia
Dementia is a medical term used to describe a group of conditions that affect memory, thinking, and daily functioning.
These conditions involve changes in the brain that can impact cognitive abilities such as memory, reasoning, communication, and decision-making.
It is important to understand that hearing loss does not cause dementia. However, research suggests that untreated hearing loss may be one of several factors associated with increased risk of cognitive decline.
Supporting hearing health and maintaining active communication can play an important role in overall brain engagement.
Alzheimer’s Disease
Alzheimer’s disease is the most common form of dementia.
It is a progressive neurological condition that affects memory, thinking, and behavior over time. Early symptoms often include difficulty remembering recent events, confusion, or challenges with familiar tasks.
As the condition progresses, cognitive abilities may gradually decline, affecting communication, decision-making, and daily functioning.
Research continues to explore many factors that influence brain health, including the role that hearing and communication may play in maintaining cognitive engagement.
Cognitive Screenings are Now a Part of Hearing Care
Because of the growing understanding of the relationship between hearing and cognitive health, cognitive screening is becoming an important part of modern hearing care.
At Solutions Hearing Center, founder Robert Kille is a Board-Certified Hearing Instrument Specialist and Certified Dementia Practitioner. Our practice also utilizes the FDA-cleared Cognivue Thrive cognitive screening system to help establish a baseline understanding of cognitive function related to communication and listening.
This screening helps guide conversations about hearing health and allows us to monitor changes over time.
If you are experiencing hearing changes or increased listening effort, a comprehensive hearing evaluation with cognitive screening can provide valuable insight into your overall communication health.
