New Research Links Hearing Loss and Dementia

Jun 23, 2023

New research shows a connection between hearing loss and dementia

A variety of studies in recent years have shown a promising connection between hearing loss and dementia. Not surprisingly, new research from the Johns Hopkins Bloomberg School of Public Health has revealed results that are consistent with previous findings.

Hearing Loss and Dementia Study Results

The most recent Johns Hopkins study included a national sample of 2,413 people, approximately 50 percent of whom were over age 80. Unlike other studies that only included individuals who could reach a clinic, data for this study was collected from in-home interviews and testing. The data gathered, then, includes a more diverse population than previous studies which only included in-clinic figures.

The results of the Johns Hopkins study may come as a surprise to some, but not so much for hearing health professionals and others who have long seen a connection between hearing loss and dementia. According to Johns Hopkins researchers, the “prevalence of dementia among the participants with moderate/severe hearing loss was 61 percent higher than prevalence among participants who had normal hearing.”

But the findings don’t stop there. Of the 853 study participants who had moderate to severe hearing loss, there was a 32 percent lower prevalence of dementia amongst those who wore hearing aids.

As with other studies conducted in the past, the Johns Hopkins researchers are quick to point out that there IS a clear connection between hearing loss and dementia risk. However, further research must be done to completely identify why there is a connection.

Hearing Loss Treatment Could Lower Risk of Dementia

At Advanced Hearing Group, we’ve long been supporters of early hearing loss diagnosis and treatment. For infants, children, and adolescents, early diagnosis and treatment of hearing loss can significantly contribute to healthy growth and development, particularly in the areas of speech, communication, and social skills.

For adults and seniors, the situation really isn’t much different. Hearing loss can be caused by a variety of things including occupational noise hazards, genetic factors, autoimmune disorders, and other conditions such as Meniere’s disease. Regardless of the cause, however, the sooner hearing loss is detected and treated, the smaller the impact on an individual’s daily life.

Benefits of hearing loss treatment for all ages include:

  • Better communication, including the ability to actively participate in conversation
  • Improved relationships with family members, friends, and even strangers
  • Increased independence and confidence with activities of daily living
  • Enhanced overall health and mental health

And now, even though the connection may not yet be fully defined, we can add ‘lower the risk of dementia and cognitive decline’ to the list.
