Dementia And Excessive Drinking

Can hearing loss treatment help prevent dementia?

According to Andrew Sommerlad, an author of the report and a senior research fellow at University College London, excessive consumption of alcohol can lead to damaged brain cells and blood vessels, shrinkage of brain tissues and severe nutritional deficiencies. And one study shows alcohol use disorder is a major risk factor for all types of dementia, especially early-onset dementia which strikes people before the age of 65.

Heres what you can do:The Lancet team suggested drinking less than 210 milliliters of alcohol weekly, the amount of alcohol which appears to reduce risk of dementia. For people who are chronic drinkers, Sommerlad said cutting back on alcohol a little each day by having smaller or lower-strength drinks is likely the safest and most effective way to reduce the consumption of alcohol.

Recognizing the problem and setting a realistic target for reducing your alcohol intake is a really important first step, he said in an email. Reducing alcohol intake is often difficult for people who have been chronic heavy drinkers, and it is a good idea to consult with a healthcare professional about how to approach this as well as seeking help from organizations and friends or family to support this process.

When Should I Get Hearing Aids

Certainly, timing seems to be critical. In other words, if you have hearing loss get it treated before you develop any cognitive decline. Frank Lin, otologist and epidemiologist at Johns Hopkins University, Baltimore puts it simply

If you want to address hearing loss well, you want to do it sooner rather than later. If hearing loss is potentially contributing to these differences were seeing on MRI, you want to treat it before these brain structural changes take place.

The realty is properly fitted hearing aids can improve communication for 90% of people with hearing loss. Wearing hearing aids can transform your life so dont delay. Call House of Hearing today and enjoy better hearing and a healthier brain.

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.

The Link Between Hearing Loss And Dementia

It has been widely reported that a hearing loss can increase the risk of a person having dementia or Alzheimers. Hearing aids have the ability to reduce that risk.

Basically, the theory is that having a hearing loss causes a person to withdraw from social situations and withdrawing from a social situation is linked to Dementia. Hearing aids help people to reengage in social situations because they can communicate better.

Thus, anyone with hearing loss should use some sort of amplification and especially those who have a hearing loss and are diagnosed with dementia as they may help.

The Links Between Hearing And Health

Hearing Aids Lower The Chance Of Dementia, Depression, And ...

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 May Reduce Risk Of Dementia Study Finds

Hearing aids may be more beneficial for your health than just improving your auditory perception. A new study out of University of Michigan finds that older people with hearing loss who get hearing aids may actually decrease their risk of developing dementia.

The study, which examined 115,000 participants over the age of 66, also found that hearing aids helped lower the risk of being diagnosed with depression and anxiety. Hearing aids also showed a positive effect on preventing falls and injuries.

What Are The Links Between Hearing Loss And Dementia

Aging is the number one cause of hearing loss in Canada. Well over half a million Canadians are living with dementia with that number set to double in the next 15 years. The two conditions appear to be connected. But just what are the links between hearing loss and dementia? Does one cause the other or is it simply a coincidental development that occurs as a result of the aging process?

A recent study indicates the risk of developing dementia as a two-fold increase with mild hearing loss a three-fold increase in risk with moderate hearing loss, and a five-fold increase in risk with severe hearing loss.

At this stage, science doesnt know the exact link between hearing loss and cognitive decline but researchers are exploring four possible links:

  • Hearing loss often leads to social isolationa well-documented risk factor for cognitive decline
  • Hearing loss requires the brain to use other processing centres such as short term memory and thinking to process sound
  • Atrophy of the parts of the brain associated with hearing due to lack of stimulation
  • Specific damage to the brain causes both hearing loss and reduced brain functionthey both share the same cause

The Negative Effects Of Untreated Hearing Loss

If left untreated, hearing loss can result in a variety of different effects on a patients body. Social isolation and lack of interaction are two of the most common effects. This can easily lead to negative emotions like depression, low self-esteem, loneliness, or even reclusiveness. Not being able to hear your surroundings is bad enough on its own. But seeing that people refuse to communicate with you because of your condition is even worse. This is where hearing aids come in to help you regain what you lost and interact again with your environment and the people around you.

The Link Between Traumatic Brain Injury And Dementia Risk

YES! Treating Hearing Loss May Prevent Dementia

Traumatic brain injury , a risk factor in midlife, is often caused by injuries sustained from automobile, sports accidents and exposure to blasts among members of the military. Severe TBI is linked to abnormal tau proteins, a biomarker of Alzheimers. People aged 50 years or older with a history of TBI are at an increased risk of dementia compared to those without TBI.

Meanwhile, falls are the leading cause of TBI among older adults. And older adults with concussion have double the risk of dementia.

Heres what you can do:To reduce risk of falls for older adults, doing balance exercises and maintaining muscle strength especially in the legs is crucial, Larson said. Lookout for items around your home which can cause a trip. And avoid walking on slick surface barefoot or with stockings.

Who Gets A Hearing Aid

The secondary goal of the study was to determine the adoption rate of hearing devices among different demographic groups.

Overall, the study found that just 12% of those diagnosed with hearing loss decide to use a hearing aid. The authors identified differences in adoption rates among different sexes, racial and ethnic backgrounds, and geographic locations.

13.3% of men with hearing loss in the United States are likely to acquire a hearing aid, as opposed to 11.3% of women with hearing loss.

13.6% of white participants with hearing loss received hearing aids, 9.8% of African Americans, and 6.5% of people with Latino heritage.

Hearing Aids Cost Too Much

At present, very few states require health insurers to cover the cost of hearing aids for people of all ages. As a result, 61 percent of users pay the bill themselves. At an average price of $1,675 per ear for equipment, fittings and evaluations, hearing aids can take a bite out of your budget. Factor in the high cost of hearing loss, however, and it is money well spent.

Measuring Adherence With Treatment

The Oticon Opn 1S HAs have a log infeature that records both the average number of hours and different listening environments in which the participant has used the HA. These data can be retrieved when the HA is connected to the program software, which will be done at all assessments. In addition, the participant will be asked to maintain a daily listening diary in which s/he records the number of hours the HA is worn.

What Are The Best Hearing Aids For Dementia

Hearing Aid To Prevent Dementia?

For patients living with both dementia, hearing loss should never be ignored, as it may exacerbate dementia symptoms, increase their disorientation and make their environment less safe .

While there are no hearing products made specifically for dementia patients, there are plenty of devices out there that can still be helpful. They range from the relatively simple, such as a wearable microphone to premium hearing aids.

Hearing loss makes living with diseases like Alzheimer’s even more challenging. For people currently affected by dementia, hearing aids or other hearing devices are recommended to improve their quality of life and make communication easier.

If you are the caretaker of someone with Alzheimer’s or a similar disease that affects cognition, you are wise to investigate what hearing devices might work best. A hearing care provider will be your ally in this journey, as they’ll know the latest products that may work for your loved one. You’ll also be able to discuss your loved one’s specific needs, habits and abilities with the hearing care specialist.

For example, hearing aids may not always be the best solution. Most premium hearing aids are designed to be discreet, so they may be too small and too easy to lose for a patient with dementia, especially if they have dexterity problems. Hearing aids also require that a person remember to keep the batteries fresh and the device clean and in good working condition. Instead, assistive listening devices may work better.

When You Wear Them Correctly Hearing Aids Can Help Prevent Dementia

Sadly, when people are prescribed with hearing aids, they dont always immediately get into the habit of wearing them. Some of the reasons why are:

  • Peoples voices are difficult to make out. In many situations, it takes time for your brain to adapt to recognizing voices again. There are some things we can recommend, such as reading along with an audiobook, that can help make this situation go more smoothly.
  • The hearing aid isnt feeling like it fits very well. If you are suffering from this issue, please let us know. They can fit better and were here to help.
  • The way that the hearing aid is advertised to work, doesnt seem to be the way its currently working. Many people need to have their settings adjusted, and calibration problems are definitely something that can be addressed by our hearing specialists.
  • Youre anxious about how hearing aids appear. Youd be amazed at the wide variety of models we have available nowadays. Additionally, many hearing aid styles are created to be very unobtrusive.

Your future cognitive abilities and even your health in general are obviously impacted by using hearing aids. We can help if youre trying to cope with any of the above. Consulting your hearing specialist to make sure your hearing aids are working for you is just part of the process and it calls for time and patience.

Randomisation Concealment And Blinding

The computer-generated randomisation sequence will be stratified by the severity of the hearing loss based on the results of the hearing assessment. Each stratification block will be associated with a random sequence of numbers assigned to the intervention and control group in random permuted blocks of 6, 8 or 10. This sequence will be stored in a password-protected server housed at the University of Western Australia and will be managed by a biostatistician not involved in this project. Once a participant consents and is enrolled, s/he will be automatically ascribed a number and group membership .

Due to the nature of the intervention, participants will know their group assignment, but research staff involved in the assessment of cognitive function, quality of life, mood and physical function will remain blind to treatment allocation. This will be achieved by directing participants to NOT: discuss any aspects of the intervention during the assessments, wear their HAs during the assessment. Binaural hearing amplifiers will be used to facilitate the communication between participants and research staff during all assessment visits .

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.

How Is Hearing Loss Linked To Dementia

Hearing test could prevent dementia development

There are several reasons for the connection of hearing loss and dementia.

  • The first one is what researchers refer to as cognitive load. If you suffer from hearing loss, your brain must work much harder to process sound. This takes away resources that could be used for other cognitive activities.
  • The other connection is related to social isolation. There are numerous studies that show a direct link between feeling lonely or isolated and dementia. When you have hearing difficulties, its more difficult to join in conversations or interact socially with friends, family and colleagues.
  • A third connection is the fact that your hearing no longer is picking up as many sounds when you have hearing loss, which means your hearing is sending fewer signals to your brain. As a result, your brain function begins to decline.
  • Many researchers believe that all these connections are likely and its probably a combination of all three.

    Hearing Aids Can Help Those Who Have Alzheimers

    If a loved one is showing signs of dementia,help them get their hearing checked sooner than later. Sometimes, undiagnosed hearing loss symptoms are thought to be Alzheimers symptoms when theyre really not.

    For those with Alzheimers, hearing loss can aggravate symptoms. A hearing impairment makes it difficult to listen, reply, and respond to verbal cues. It escalates feelings of confusion, isolation, and paranoia.Hearing aids can help relieve Alzheimers symptoms, and several styles are easy for a person with cognitive impairment to use. An American Journal of Epidemiology study found that hearing aids slowed the rate of memory decline and improved the quality of life for Alzheimers patients with hearing loss.Its important to find out the facts.

    Wearing Hearing Aid May Help Protect Brain In Later Life

    A new study has concluded that people who wear a hearing aid for age-related hearing problems maintain better brain function over time than those who do not.

    The research was conducted by the University of Exeter and King’s College London and is presented at the Alzheimer’s Association International Conference in Los Angeles, in the PROTECT online study of 25,000 people aged 50 or over.

    The findings provide early evidence that encouraging people to wear an effective hearing aid may help to protect their brains and reduce their risk of dementia.

    Aoife Kiely, Research Officer at Alzheimers Society, said:

    The link between hearing loss and the risk of developing dementia has been an area of interest over recent years, and this research is further evidence that using a hearing aid for hearing difficulties in mid-life could help a person maintain their brain function as they get older and might also reduce their risk of dementia.

    In this study, people using hearing aids had faster reaction times than those who didnt, which might indicate better concentration. Being able to stay tuned into conversations and day-to-day life is key in reducing the feelings of isolation that we know many people with dementia experience, which is why were currently funding a project to improve hearing problems in care homes to help make sure anyone with a hearing problem can receive the support they need.”
