Loss of Vision and Hearing May Cause Cognitive Decline in Seniors

It’s not uncommon for seniors to experience hearing and vision loss. Sadly, these changes can cause both physical and emotional hardships. They may feel a loss of independence, an inability to do the things they love, and a disconnect from the world around them. Beyond these discomforts, with the loss of vision and hearing, they may experience Cognitive Decline.

Read on to learn more about how hearing and vision loss causes dementia and cognitive Decline in seniors.

Vision Loss and Cognitive Decline in Seniors

The most recent study on the relationship between vision loss and cognitive decline looked at two datasets. This data covered 16 years and included more than 33,000 people aged 60 and up. Published in JAMA Ophthalmology in September 2017, it concluded that “vision dysfunction…was associated with poor cognitive function.”

This confirms a study conducted at the University of Michigan in 2010. This six-year study followed 625 elderly participants and had similar findings. These findings were published in the American Journal of Epidemiology, and concluded that “untreated poor vision is associated with cognitive decline, particularly Alzheimer’s disease.”

Hearing Loss and Cognitive Decline

Hearing loss also plays a part in cognitive decline in seniors. The reason for this is unclear, but there is speculation that  uncorrected deficits in vision and hearing may accelerate this.

The New York Times recently interviewed Dr. Suzann Pershing – lead author of the study and an ophthalmologist at Stanford University School of Medicine – to learn more. Pershing said that “this association doesn’t prove vision loss causes cognitive decline. Intuitively, it makes sense that the less engaged people are with the world, the less cognitive stimulation they receive, and the more likely their cognitive function will decline.”

A study published in JAMA Internal Medicine in 2013 observed 1,984 adults with an average age of 77. The study confirms that “hearing loss is associated with accelerated cognitive decline and incident cognitive impairment.” Also noteworthy, Adults with hearing loss will experience cognitive decline 30-40% faster than those with normal hearing.

A Causal Relationship?

According to Dr. Frank R. Lin, otolaryngologist at the Johns Hopkins Center on Aging and Health, said, “Older adults with hearing loss face an increased risk of dementia even when you control for diseases like diabetes and high blood pressure. So we think they’re causally related.”

There are a few reasons this may happen:

  • hearing-impaired people tend to become isolated and lack stimulation
  • hearing loss causes brain atrophy that affects memory and thinking
  • the brain has to work harder to understand muffled or distorted speech

But There is Hope for Improvement.

Dr. Pershing also said that cognitive function can be improved if vision problems are treated. Regular visits with your ophthalmologist can lead to improvement, and help prevent deterioration.

Almost two-thirds of adults over the age of 70 have hearing loss, yet they remain significantly undertreated. Hearing aids are affordable and accessible. Hearing is again possible with treatment.

Cognitive decline is a problem for seniors, but now that we know the causes we can help prevent deterioration. With this information, our elderly loved ones can live fuller lives, and tackle future health problems.
