Medical science has made significant strides in comprehending the interplay between different aspects of our health. And in recent years, one emerging area of interest that I have followed revolves around the potential connection between untreated hearing loss and dementia. While this subject continues to draw attention and raise questions, it is crucial to approach the discussion with a rational and evidence-based perspective, examining what the research and data suggest so we may make better-informed and proactive decisions about our own health and well-being.

That said, if you or a loved one are experiencing hearing loss and are curious to explore the possible link between hearing loss and dementia, I’ve prepared this article for you.

Can Loss of Hearing Lead to Dementia? – What the Research Shows Us

Dementia — a general term for loss of memory, language, problem-solving, and other thinking abilities that can interfere with daily life — has been a focus of researchers, healthcare professionals, and the public alike. While scientists still can’t draw a definitive straight line from hearing loss to dementia, an impressive amount of recent research points to a correlation between individuals with untreated hearing loss and a decline in cognitive function, including memory. In just the past few years, scientists have discovered evidence that:

  • Hearing impairment is one of the top risks for dementia, with 8% of dementia cases worldwide linked to a decline in hearing.
  • There is a correlation between the degree of hearing loss and dementia. The greater the severity of hearing loss in older adults, the more likely they are to have dementia.
  • Dementia risk declines as hearing loss declines; evidence that hearing loss is a modifiable risk for dementia.
  • The likelihood of dementia is lower among hearing aid users compared to non-users.

A Modifiable Risk: The Role of Hearing Aids in Helping Reduce the Risk of Dementia

Mounting concern and research into the health effects of untreated hearing loss have prompted investigations into whether conventional aids can effectively reduce these risks. Studies have provided compelling evidence that hearing aids may lead to numerous advantages besides just improved hearing. So, what is it about hearing aids that may help reduce the risk of cognitive decline and dementia?

  • Hearing loss can lead to reduced auditory stimulation of the brain, which may result in atrophy of some brain regions responsible for processing sound. This lack of stimulation could possibly accelerate cognitive decline. By using hearing aids to amplify sounds, the brain receives increased auditory input, which may help keep those brain areas active and engaged.
  • People with untreated hearing loss often strain to understand conversations and sounds, placing a higher cognitive load on their brains. This additional cognitive effort can leave fewer cognitive resources available for other mental processes, potentially contributing to cognitive decline. Hearing aids can ease the cognitive burden of listening and understanding, allowing the brain to allocate resources more efficiently.
  • Addressing hearing loss early with hearing aids may be crucial in mitigating its potential impact on cognitive function. As the previous research suggested, untreated hearing loss may be associated with an increased risk of dementia later in life. By using hearing aids to manage hearing loss early on, individuals may be able to reduce the long-term risk of cognitive decline.

Please note that despite the evidence, we need more research to understand the mechanisms and extent of this relationship fully. However, the most important step you can take is to consult with a Certified provider to determine appropriate interventions and management strategies tailored to you personally.

This is a subject of personal importance to me. A recent study from Johns Hopkins revealed that hearing aids slowed cognitive decline in older adults with mild to moderate hearing loss by 48%.

Last week, I saw a patient in the office that I had recommended hearing aids to a year ago. The patient’s wife mentioned how much more he’d been participating in conversations with family and friends. Being more engaged will help his emotional well-being as well as slow his cognitive decline by keeping his brain more stimulated. I explain to my patients with hearing loss that hearing aids will not only help them enjoy social time with family and friends but, just as importantly, hearing loss is the number one modifiable risk factor for cognitive decline that they can control.
