Understanding the Link Between Hearing Loss and Cognitive Decline: An Insight by Berkeley Hearing Center

by | Jun 25, 2023 | Cognitive Decline, Patient Resources

Hearing loss has long been considered a natural part of aging. However, what many don’t realize is that untreated hearing loss can significantly impact other aspects of health, including cognitive function.

Recent studies have shown a compelling link between untreated hearing loss and cognitive decline. As hearing health experts at Berkeley Hearing Center, we have delved into this research and believe it’s crucial to spread awareness about this consequential association.

The Prevalence of Hearing Loss

Hearing loss is an incredibly common condition, especially among older adults. According to the National Institute on Deafness and Other Communication Disorders, approximately one in three people in the United States between the ages of 65 and 74 have hearing loss. For those older than 75, the ratio increases to one in two.

Despite hearing loss’s prevalence, only about 20 percent of those who could benefit from treatment actually seek help. Many people delay seeking treatment for an average of seven to ten years after their initial diagnosis. This delay, combined with the link to cognitive decline, means that untreated hearing loss can silently pave the way to significant cognitive challenges over time.

Understanding the Link Between Hearing Loss and Cognitive Decline

Cognitive decline refers to a decrease in cognitive capabilities, such as memory, attention, and thinking skills. When severe, this decline can manifest as dementia or Alzheimer’s disease, both of which can severely impact an individual’s quality of life.

Several theories seek to explain the connection between untreated hearing loss and cognitive decline. One prominent theory posits that the extra effort needed to understand speech with hearing loss can take up cognitive resources, leading to cognitive overload. Over time, this cognitive overload can result in a decline in other cognitive abilities.

Another possible explanation lies in the effects of social isolation. Difficulty hearing can lead to avoidance of social situations, leading to fewer mentally stimulating interactions and a greater likelihood of cognitive decline.

The Research on Hearing Loss and Cognitive Decline

Numerous studies have substantiated the link between hearing loss and cognitive decline. A prominent study published in the Journal of the American Geriatrics Society found that cognitive abilities (including memory and comprehension skills) decline 30–40 percent faster in people with hearing loss than in those without.

Another study published in JAMA Otolaryngology-Head & Neck Surgery found that among a sample of nearly 2,000 older adults, those with hearing loss had a 24 percent increased risk for cognitive decline compared to those without hearing loss.

How Can Addressing Hearing Loss Help?

Treating hearing loss as soon as it’s diagnosed can help to slow or even prevent the associated cognitive decline. Hearing aids, the most common treatment for hearing loss, not only amplify sound but also reduce the strain of deciphering speech, freeing up cognitive resources for other tasks.

Moreover, improved hearing can encourage participation in social activities, helping to stave off the negative effects of social isolation on mental health.

John Chakan

How did I get here? That’s an interesting story. I was born and raised in the suburbs of New York City. I dreamed of being a professional baseball player (Go Yankees!), but my promising career was cut short by a condition known as “not being good enough.” When I wasn’t playing baseball (or soccer or football or basketball) as a kid, I was spending my summers attending, and then working at, a summer camp in Northern California on a livestock ranch. While it might seem a bit incongruous for a suburban New Yorker to spend his summers milking cows, chopping wood, and canoeing down the Russian River, I fell in love with the interconnected community of summer camp, and I also fell in love with California.
