Can Tinnitus Lead To Alzheimer’s

Metabolic Connectivity Of Glucose Metabolism

What is tinnitus?

In MCI_NT, negative metabolic connectivity was mainly detected between the parietal and temporal regions, such as Heschls gyrus, and between the parietal and limbic regions, including the amygdala, hippocampus, and parahippocampus. Moreover, MCI_NT showed strong metabolic connectivity within the intra-hemispheric regions, such as the frontal, parietal, and occipital regions, and between the frontoparietal regions . In contrast, in MCI_T, different from MCI_NT, inter-parietal connectivity was weakened or absent with the other regions, but there was strong connectivity between the motor regions and both temporal and limbic regions . Compared with the MCI_NT group, the MCI_T group had significantly lower metabolic connectivity between the rectal gyrus and inferior frontal gyrus between the SMA and parietal region, including the angular gyrus and precuneus between the orbitofrontal and inferior temporal region between the precuneus and inferior occipital gyrus and between the fusiform gyrus and insula but had higher metabolic connectivity between the parietal and temporal and parietal and limbic regions .

Misdiagnosis And Further Links

Hearing loss can sometimes be misdiagnosed as dementia. People with dementia can have difficulty communicating with others, including finding the right words, or signs, for what they want to say. They may have difficulty processing what theyve heard, particularly if there are distractions. According to some researchers, this difficulty in processing information can be one of the first signs of cognitive impairment.

We also know that hearing loss can speed up the onset of dementia, or make the symptoms of dementia appear worse, and dementia can heighten the impact of hearing loss.

Linking Tinnitus And Dementia

Tinnitus makes it difficult for many people to relax and focus. This constant attention can cause mental fatigue, exhaustion, and depression. Insomnia and troubled sleep have also been linked to tinnitus, and lack of sleep can have serious, detrimental effects to anyones health. When combined with the social isolation and lack of communication that hearing loss can cause, tinnitus can deeply influence an elderly persons health and wellbeing.

Tinnitus and hearing loss also cause the brain to reorganize. In order to cope with the loss of hearing, the brain stops performing certain functions in order to compensate. The areas of the brain dedicated to memory and concentration are the first to go, and the loss of these functions can lead to the onset of dementia.

Tinnitus May Warn Of Increased Risk For Alzheimers Parkinsons

Tinnitus, a sensation of sound without any source, appears to precede Parkinsons and Alzheimers diseases and may serve as a sign of increased risk for those conditions, according to a recent study.

The study, Tinnitus and risk of Alzheimers and Parkinsons disease: a retrospective nationwide population-based cohort study, was published in the journal Nature Scientific Reports.

Rates of tinnitus increase with age and studies have found that hearing loss, as well as central auditory dysfunction more generally, are associated with higher risks of cognitive dysfunction, particularly dementia, control of attention, and working memory.

Past studies, however, have not examined the relationship between tinnitus, Parkinsons, and Alzheimers in a population-based way.

A team of researchers from various Taiwanese institutions recently examined this association using records from Taiwans National Health Insurance system. The NHI records provide a large and nationally representative patient sample with long follow-up periods, as participation is nationwide and mandatory.

They identified 12,657 tinnitus patients and 25,314 control patients without tinnitus. Over a 10-year follow up period, 398 of those with tinnitus and 501 without developed Alzheimers.

A further 211 tinnitus patients and 249 control patients developed Parkinsons.

The Link Between Tinnitus And Dementia

Many studies have remarked on the link between hearing loss and dementia, but many people still wonder if tinnitus has any links to the condition as well.

Tinnitus

Recent studies have shown that there is an irrefutable link between hearing loss and dementia in older patients. As their hearing worsens, they might have trouble interacting with people. Many older people who struggle to communicate with family members, friends, and nurses might withdraw, which can have a negative impact on their health. Social isolation has been shown to increase the onset and effects of dementia, and hearing loss can directly cause isolation.

There is also the issue of misdiagnosis. Certain symptoms of hearing loss might be misinterpreted as dementia. In one case, a woman was diagnosed with a serious case of dementia. After she was fitted with hearing aids, doctors were able to determine that many of her symptoms weren’t caused by a mental condition, but a hearing problem.

Early detection of hearing loss is key in these cases. Once the hearing loss is diagnosed, measures can be taken to ensure that the patient’s health and well-being are better taken care of. Hearing aids can allow them the freedom to communicate, and an active social life can help prevent the onset of dementia.

How Hearing Aids Can Help

As Signia continuously develops its hearing aid technology, the opportunities for better hearing grow. Hearing aids can have a profoundly positive impact on the elderly, especially those who long to communicate and hear the world around them. These interactions can improve their quality of life and prevent isolation and depression two factors that have a serious impact on dementia.

The earlier hearing loss and tinnitus are diagnosed, the faster treatment can begin. Consider visiting a hearing care professional for a hearing test, and talk to your loved ones about hearing aids. Better hearing can improve present-day interactions and future health.

How Do Alzheimers Disease And Hearing Loss Connect

There are three ways hearing loss and dementia have been linked in the past:

  • An underlying cause for both conditions
  • A decrease in sound-related input causes brain shrinkage
  • More brain resources are needed to compensate for hearing loss, making them unavailable for other tasks

The researchers at Newcastle University suggest that the connection between hearing loss and Alzheimers disease lies in the brains memory center, located deep in the temporal lobe.

The memory center is where both long-term memory of places and events and short-term memory are stored. In addition, the manipulation of auditory information is also completed in this area of the brain.

Professor Tim Griffiths from Newcastle Universitys Faculty of Medical Sciences explains, The challenge has been to explain how a disorder of the ear can lead to a degenerative problem in the brain. We suggest a new theory based on how we use what is generally considered to be the memory system in the brain when we have difficulty listening in real-world environments.

Brain scans show us that hearing loss may contribute to a faster rate of atrophy in the brain, Lin says. Hearing loss also contributes to social isolation. You may not want to be with people as much, and when you are you may not engage in conversation as much. These factors may contribute to dementia.

As you walk, your ears pick up subtle cues that help with balance. Hearing loss mutes these important signals, Lin notes. It also makes your brain work harder just to process sound. This subconscious multitasking may interfere with some of the mental processing needed to walk safely.

Hearing Aids Can Help Prevent Dementia

Numerous studies show that hearing aids not only improve a persons hearingthey also help preserve a persons independence, mental abilities, emotional and physical health, and work, home, and social lives. A full, happy life keeps your brain active.

Early identification and treatment of a potential hearing loss helps minimize risks later in life.

Sudden Idiopathic Hearing Loss

Sudden hearing loss is a perplexing problem. Modern medicine has few if any successful treatments for it. Physicians impulsively inject steroids that have been shown to work no better than an inactive placebo.

Supplemental vitamin A vitamin C , vitamin E and selenium twice daily for 30 days following sudden onset of hearing loss fared better than patients who received steroids alone.

Patients treated with vitamin E after sudden onset of idiopathic hearing loss fared better than patients given magnesium, steroids, bed rest alone.

Intravenous magnesium improves recovery from sudden onset hearing loss.

When hyaluronic acid is added to injected steroids to treat sudden idiopathic hearing loss, treatment improves.

The use of vitamin E and vitamin C was far superior for sudden idiopathic hearing loss.

The delivery of intravenous vitamin C for 10 days plus 2000 mg vitamin C orally for 30 days enhanced hearing recovery among patients with sudden idiopathic hearing loss.

Zinc gluconate supplementation enhanced hearing recovery among patients with idiopathic sudden hearing loss.

Hearing Loss As A Risk Factor For Dementia

There is strong evidence to show that:

  • mild hearing loss doubles the risk of developing dementia
  • moderate hearing loss leads to three times the risk
  • severe hearing loss increases the risk five times.

But can steps be taken to reduce or avoid this risk? An international review in medical journal The Lancet, published in 2017, suggested that hearing loss is one of nine key risk factors for dementia that are possibly modifiable .The review suggested that one in three cases of dementia could be prevented if more people looked after their health throughout their lives. Other key risk factors for dementia include social isolation, smoking and depression.

Unaddressed hearing loss in mid-life was predicted to be the highest potentially modifiable risk factor for developing dementia. It is potentially responsible for 9% of cases. This is hugely important. Can addressing hearing loss for example, by using hearing aids reduce this risk? Its vital we find out.

  • How Hearing Loss May Change The Brain

    Hearing loss does seem to shrink some parts of the brain responsible for auditory response. In a study led by Jonathan Peelle, now at Washington University in St. Louis, older adults underwent brain scans while they listened to sentences of varying complexity. They also took tests that measured gray matter, the regions of the brain involved in muscle control, and sensory perception such as seeing and hearing, memory, emotions, speech, decision making, and self-control.

    It turned out that the neurons in people with hearing loss were less active when they focused on complex sentences. They also had less gray matter in the auditory areas. These effects may accumulate with time or be triggered by age: In other research, Peelle found that older adults with hearing loss do worse on speech comprehension tasks than younger adults with hearing loss.

    Do Hearing Aids Reverse Cognitive Decline

    Dr. Curhans research didnt get a clear answer to this question. Among volunteers with severe hearing loss, those who wore hearing aids had a slightly lower risk of subsequent subjective cognitive decline than those who didnt. But the effect was too small to be statistically significant.

    Because they keep you connected withothers, hearing aids can help preventsocial isolation.

    She would like to see hearing aids and cognitive decline get a hard look. There isnt much evidence over long periods of time and what we have isnt conclusive, she notes. Several studies have found no relation between hearing aid use and cognitive function decline, while others have been suggestive of a possible association, she told Healthy Hearing. This relation merits further study.

    One recent and very large observational study did shed more light on this issue, finding that hearing aids appeared to delay the onset of cognitive impairment and dementia, along with depression and falls that cause injuries. However, it was not a randomized controlled trial, so the results could have been for other reasons .

    As well, one large 2018 study analyzed results from more than 2,000 Americans age 50 and up who took word recall tests every two years for up to 18 years. Among those who acquired hearing aids along the way, the evidence suggested that the aids slowed the rate they lost memory of words.

    What Research On Dementia And Hearing Loss Reveals

    Most recently, a study published in July 2021 found that people who struggle to hear speech in noise were more likely to develop dementia than those with normal hearing, as measured over an 11-year period. This was the first time that speech in noise was specifically studied. However, the study wasnt capable of determining if untreated hearing loss caused the dementia, only that theyre linked.

    In a different study, a team at Johns Hopkins looked at cognitive impairment scores over six years for nearly 2,000 seniors. They concluded that those with hearing loss had a faster decline. The volunteers were all cognitively normal when the research began. But by the studys end, people with hearing loss were 24 percent more likely to meet the standard of cognitive impairment compared to people with normal hearing.

    Another approach is to ask people whether theyve noticed a change. Measures of subjective decline can pick up losses before theyll show up on a test. A large studyusing data drawn from more than 10,000 men age 62 and upran over eight years. It found that the greater their hearing loss, the more likely men were to express concerns about their memory or thinking over time. With even a mild hearing loss, their chance of reporting cognitive decline was 30 percent higher than among those who did not report any hearing loss. With moderate or severe hearing loss, the risk was 42 and 52 percent higher.

    Folate Fights Free Radicals

    Low levels of folate have been linked to higher incidence of hearing loss. In one study, steady supplementation of folic acid resulted in a slower rate of hearing lossparticularly in the frequencies associated with speech.

    How does folate improve hearing? A few things seem to be at play. First, folic acid appears to help the body metabolize homocysteine, an amino acid that can reduce and impair blood flow to the inner ear . Research strongly suggests that proper metabolization of this amino acid plays a significant role in the development and progression of sensorineural hearing loss.

    Folates are also an antioxidant that helps fight off free radicalsthose pesky little molecules that have gained a reputation for causing a whole host of issues in the body over time. Free radical activity can reduce blood flow to the inner ear, as well as damage our ears delicate sensory cells needed for healthy hearing. And once those cells are destroyed, they cannot grow back.

    What sparks free radical production? Often, its a stressor on the body, such as excessive or loud noise. Research has shown exposure to loud noise triggers an increase in formation of these damaging free radicals.
