The truth is, however, that the condition can strike even the youngest among us — more than one in 1,000 babies screened has some form of hearing impairment, per Centers for Disease Control and Prevention data — and it can trigger other health problems, too.
Take cognitive decline, for example, which can lead to Alzheimer’s disease or another form of dementia. Research has long pointed to links between hearing loss and reduced brain functioning over time, but the statistics may surprise you.
Consider these startling findings:
- On average, seniors with hearing loss experience significantly reduced cognitive function 3.2 years before their normal-hearing counterparts.
- Hearing-impaired seniors experience thinking and memory problems 30 to 40 percent faster than their normal-hearing counterparts.
- Older adults with a hearing disability may lose over a cubic centimeter of brain tissue annually beyond normal shrinkage.
- Those with hearing loss are two, three, or nearly five times as likely to develop dementia, depending on the severity of the hearing impairment.
So what’s the connection between hearing impairment and cognitive decline? It’s not completely clear how hearing loss, which is also associated with diabetes, cardiovascular disease, and other common public-health challenges, contributes to development of dementia.
What is clear, however, is the importance of regular hearing checkups to help stave off the threat of cognitive impairment. Tackling risk factors such as hearing loss earlier on could cut dementia cases by a third, according to a research collaborative led by UK psychiatry professor Gill Livingston and involving the Alzheimer’s Society, Alzheimer’s Research UK, and other individuals, institutions, and organizations.
As one of your most crucial senses for communication and perception, hearing not only helps you stay connected to the world but helps keep your brain sharp. Give your hearing health and overall wellness a hand by staying active, eating a diet rich in important nutrients, avoiding excess noise, and scheduling regular hearing checkups.
Munch to Better Hearing
Hearing power is brainpower, and some key foods can help! Certain vitamins and minerals can go a long way toward supporting your hearing wellness, according to HealthyHearing.com. In honor of National Nutrition Month in March, check out these examples:
These reliable delights are rich in potassium, an important mineral for regulating blood and tissue fluid levels — including in the inner ear, which plays an important role in hearing and balance.
This versatile vegetable with an edible stalk and green flowering head provides folate, which studies have linked to healthy outcomes such as decreased risk of hearing impairment among older men.
These juicy fruits — easy to grow and delicious cooked in a sauce or served raw — offer magnesium, which, combined with vitamins A, C, and E, help thwart noise-induced hearing loss.
This flavorful part of the bird — along with other foods such as beef, oysters, and legumes — delivers zinc, which supports the immune system and may help fight tinnitus or ringing in the ears.
