Hearing Loss and Dementia
We often think of hearing loss as a natural part of aging. However, recent medical research has revealed a much more profound connection between our ears and our minds.
Because we know that age is a risk factor for dementia, it's common for people to associate cognitive decline with the natural aging process. However, there is sufficient evidence to indicate that untreated hearing loss increases a person's risk of developing dementia. In fact, understanding the link between hearing loss and dementia is one of the most important steps you can take for your long-term cognitive health.
According to the Alzheimer's Association1, around 6.7 million Americans aged 65 and above are living with Alzheimer's disease. Seventy-five percent of them are aged 75 or older.
- Alzheimer's is a type of dementia that is characterized by a progressive loss of cognitive function.
- Dementia is a general term for a decline in cognitive function that affects memory, thinking, and behavior.
Because we know that age is a risk factor for dementia, it's common for people to associate cognitive decline with the natural aging process. However, there is sufficient evidence to indicate that untreated hearing loss increases a person's risk of developing dementia.
In this article, we'll discuss the latest research on the connection between hearing loss and dementia, the costs (both financial and emotional) of untreated hearing loss, and the benefits of regular hearing screenings and treatments in reducing the risk of cognitive decline.
Does Hearing Loss Cause Dementia?
While research is ongoing, there’s growing evidence to support that mid-life hearing loss is the single largest modifiable risk factor for developing dementia.2 This means that while we can't change our genetics, we can address our hearing health to potentially lower our risk.
There’s no clear-cut answer as to why hearing loss and dementia are so closely intertwined, but here are three theories:
- Cognitive Load. When you struggle to hear, your brain has to work overtime just to decode sounds. This consumes cognitive resources that would otherwise be devoted to memory and thinking.
- Brain Atrophy. When the auditory cortex isn't receiving stimulation, it can lead to structural changes in the brain. In fact, those with hearing loss lose an additional cubic centimeter of brain tissue each year compared to those with normal hearing.3
- Social Isolation. One of the most common side effects of untreated hearing loss is social withdrawal. Isolation is a well-known fast track to cognitive decline.
Can Hearing Aids Reduce the Risk of Dementia?
Not Wearing Hearing Aids: What’s at Risk?
Many people wait an average of 7-10 years before addressing their hearing loss. In fact, wearing hearing aids can be a key factor in brain health. Furthermore, studies have shown that even a mild, untreated hearing loss can double the risk of dementia, while severe, untreated loss can increase the risk fivefold.5
When we ignore the signs of hearing impairment, we aren't just missing out on bird song or laughter; we are depriving the brain of the vital exercise it needs to stay sharp.
What about the financial impact?
Untreated hearing loss can also come with an enormous economic burden. Here are a few examples of how:
- Reduced earning potential due to workplace communication difficulties
- Increased healthcare costs from falls and hospitalizations
- Addressing other health issues stemming from untreated hearing loss.
Additionally, individuals with hearing loss tend to put off doctor visits or skip preventive checkups until a health concern feels more urgent. Individuals with hearing loss may also find it challenging to adhere to medication or treatment instructions they didn’t hear clearly, leading to further delays in receiving the necessary care.
