<\/span><\/h2>\nThe links between hearing loss and a host of problems have prompted research on the question of how better hearing might protect you. The impact of hearing aids is a new and growing field, and the findings are mostly upbeat. More than a decade ago, research suggested that\u00a0hearing aids improve overall quality of life.\u00a0<\/p>\n
Hearing loss is far easier to correct than many of the problems it may be related to, so this is great news for public health, experts say.<\/p>\n
A breakthrough came last year with a large\u00a0study\u00a0analyzing what happens in the three years after you get your first hearing aid. It found that among people with newly-diagnosed hearing loss, getting an aid cut the risk of developing dementia by 18 percentage points, the risk of a fall-related injury by 13\u00a0percentage points and the risk of developing anxiety or depression by 11 percentage points.<\/p>\n
To reach this conclusion, a large team of researchers led by Elham Mahmoudi, a health economist at the University of Michigan, pulled five years of claims data nationwide from a managed care provider, finding nearly 115,000 seniors who met their criteria\u2014a new diagnosis of hearing loss and no history within the previous year of the medical issues under study. The team also looked for other conditions associated with hearing loss like diabetes, obesity and heart problems and adjusted their calculations to make this sample typical. The next step was to analyze the sample\u2019s history for the next three years.<\/p>\n
The study confirmed earlier evidence that people with hearing loss are more likely to develop dementia\u2014in this sample, 13.9% did, compared to about 12%\u00a0in the general population age 66 and up. Also, nearly 13%\u00a0of the sample had an injury in a fall (compared to 7.5%) and 33.6% were depressed (compared to 25.2%).<\/p>\n
Only a randomized trial can show cause-and-effect, so this study isn\u2019t conclusive that hearing aids protected their users, though it seems likely. \u00a0\u00a0<\/p>\n
<\/span>Hearing loss and cognitive decline<\/span><\/h2>\nIt also doesn\u2019t mean hearing aids solved an underlying issue. Instead, hearing better probably bought time, delaying onset of symptoms. Left untreated, hearing loss may be a sign that dementia, for example, could come about two years earlier, according to research\u00a0we reported in this article on\u00a0hearing loss and cognitive decline.\u00a0<\/p>\n
Scientists suspect a classic feedback loop: Cognitive decline makes it harder to understand what you hear, and hearing loss puts a burden on your cognitive resources, leading to changes in your brain. Isolation, loneliness and depression feed into this loop as well. Loneliness increases your risk of dementia by as much\u00a0as 40%, and may even be a symptom of early brain changes, as suggested by a small brain scan\u00a0study.\u00a0<\/p>\n
Catching hearing loss early may be important. If you can hear a sound of 25 decibels\u2014about the loudness of a whisper\u2014you are considered to have normal hearing. But even\u00a0slight hearing loss could be linked to cognitive decline, according to 2019\u00a0research\u00a0from a team based at Columbia University. In fact, the team found a significant link to cognitive decline for every 10 decibels of loss and most dramatically in those who were just 10 decibels short of perfect hearing.<\/p>\n
Middle age may be the turning point. In another 2019\u00a0study\u00a0of more than 16,000 Koreans newly diagnosed with hearing loss over a decade, hearing loss emerged as a significant risk factor for dementia most strongly in people ages 45 to 64. \u00a0<\/p>\n
Don\u2019t feel doomed! You\u2019re not guaranteed to develop dementia because you haven\u2019t checked your hearing or leave your hearing aids in that cute little box.\u00a0But wearing hearing aids is one of the things you can do relatively easily to protect yourself against a debilitating illness as you age.\u00a0<\/p>\n
<\/span>Hearing loss affects mental health<\/span><\/h2>\nThe effect on your social life and mood may creep up on you, especially if you can\u2019t understand speech in a noisy environment. In people under 70, every decibel drop in this kind of perception raises the risk of being severely lonely, a Dutch study\u00a0found. Not wearing hearing aids is a risk factor for loneliness in other\u00a0research. And there is a bit of\u00a0evidence\u00a0that getting a hearing aid or cochlear implant can prevent loneliness from deepening over time. The key is how you feel.\u00a0One person might not socialize often but feel rich in friendship and another look popular to observers but feel lonely. Either way, hearing loss can affect how other people perceive you, as Abrams observed.<\/p>\n
Loneliness too easily cascades into depression.\u00a0In a 2019\u00a0overview\u00a0of 35 studies covering more than 147,000 older adults, hearing loss increased the odds of depression by 47% (it wasn\u2019t clear in this overview that hearing aids helped). Suicidal thinking, most often a symptom of depression, is\u00a0linked\u00a0to hearing loss as well.<\/p>\n
<\/span>The link between hearing loss and falls<\/span><\/h2>\nBoth hearing loss and\u00a0depression\u00a0are associated with a higher chance of a fall, a growing problem among the elderly, and falls tend to deepen depression and increase the risk of death.\u00a0<\/p>\n
A 25 decibel hearing loss, equivalent to going from normal to mild hearing loss, may triple your chance of falling, according to a\u00a0study\u00a0of people in the middle years\u2014from 40 to 69\u2014when hearing loss often first develops and you\u2019re less likely to guard against falls.<\/p>\n
Unfortunately,\u00a0research\u00a0has not supported the idea that people with balance issues are more stable when wearing hearing aids. \u00a0<\/p>\n
<\/span>The link because hearing loss and cardiovascular disease<\/span><\/h2>\nAge-related hearing loss is usually in the higher frequencies. But Abrams recalls that during his years in a Veterans Administration hospital, he saw men with gradual loss in their low-frequency hearing. It turns out that\u00a0low-frequency hearing loss\u00a0may be a\u00a0marker\u00a0of a greater chance of stroke, peripheral vascular disease\u00a0and heart attack.<\/p>\n
In a 10-year\u00a0study\u00a0of nearly 4,000 British men age 63 to 85 who were living in the community, men with untreated hearing loss were more than a third more likely to have a stroke or heart attack and to die of a cardiovascular event than men without hearing issues, but wearing a hearing aid lowered their risk. Although earlier research suggested that smoking and atherosclerosis explained the link between hearing loss and cardiovascular problems, this new study found a link even in men who didn\u2019t smoke or have other heart risks.\u00a0<\/p>\n
<\/span>What about longevity?<\/span><\/h2>\nResearch in Iceland also\u00a0linked\u00a0untreated hearing loss in men to a greater chance of dying in the next five years, most often from heart disease.<\/p>\n
Is there research suggesting that people with hearing loss who wear hearing aids live longer? Not yet, Abrams noted. But two large studies are slated to wrap up in 2021, which will address how hearing aids improve overall health. May we invite you to \u201cstay tuned?”\u00a0\u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":1,"featured_media":4470,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[5],"tags":[874,273,2970],"class_list":["post-4469","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-aids-hiv","tag-benefits","tag-health","tag-hearing-aids"],"yoast_head":"\n
