Telling The Difference Between Sight Loss Symptoms And Dementia
It is often hard to separate the signs of sight loss from those of dementia, and often one condition may mask the other.
Having difficulty with any of the following may suggest a person is having problems with their sight.
- coping with low light, bright light or both
- finding things
- locating food on their plate
- seeing well even with glasses on.
Some of these issues may be caused by the persons dementia. However, it is important to have the person’s sight tested as difficulties with their sight could be making their confusion worse.
Despite what many people think, it is possible for a person with dementia to have a sight test. The test can be adapted for people with dementia, if it is needed.
Hearing Loss And Dementia: Nancys Story
It is essential to recognise and respond sensitively to hearing loss in people with dementia. If a person with dementia is unable to communicate problems they are having with their hearing, this is likely to cause distress. They may well be frustrated or aggressive, but unable to say why and these reactions then may be interpreted as being a result of the dementia.
Both identification and management of hearing loss are particularly important where a person has dementia. Without this, the dementia may appear worse or get worse. For example, if a person with dementia is having difficulty using their hearing aid say they dont remember to use it or dont recognise it as their hearing aid this is likely to make it harder for them to follow communication and may make them seem more confused and withdrawn.
Both hearing loss and dementia can cause social isolation. Where someone is experiencing both of these, this can be compounded. For example, the person may be unwilling to attend social functions or participate in activities because their problems with hearing and memory make social situations so much more uncomfortable.
Management Of Hearing Loss
There are various options for the management of hearing loss. The most commonly used equipment is digital hearing aids. These work by amplifying noise and delivering this to the air canal. It is important that hearing aids are cleaned and maintained and batteries replaced as appropriate.
Audiology clinics usually provide maintenance and battery replacement services. In some areas there are services for care homes where staff are supported to carry out basic maintenance of hearing aids. Care providers should be aware of how to access these.
Other equipment or interventions include cochlear implants, which are suitable for people with severe or profound deafness who cannot use hearing aids.
Assistive technology such as FM or infrared listening equipment and induction loops are also available again, this works by amplifying and directing sounds. Other assistive devices for daily living include vibrating alarm clocks, flashing doorbells and flashing smoke alarms.
We can also make adjustments to a persons environment that can help manage hearing loss, for instance, limiting the amount of background noise and ensuring good lighting to enable people to lipread.

The Link Between Hearing Loss And Cognition
Hearing loss is the third most common physical condition in Beaufort and other communities throughout the U.S., ranking behind arthritis and heart disease. Because of its prevalence many consider hearing loss to be a nuisance and skip treating it but faking their way through the day can have dire consequences. A study conducted by Yune S. Lee, PhD, at The Ohio State University showed that even in patients who are young, minor hearing loss was associated with changes in blood flow and unusual activity in the brains frontal cortex. Eventually, this can lead to dementia later in life Lee concludes that the risk for patients with mild hearing loss is twice as high as those in the general population.
There are multiple theories explaining the link between hearing loss and dementia. Several key factors include:
Regardless of the exact reason for the link between hearing loss and dementia, the evidence is undeniable. More than one-third of dementia cases in adults over the age of 60 are associated with hearing loss, even after taking into account variables like sex, age, race, education, lifestyle factors and overall health. Hearing loss patients experience cognitive decline at a rate that is 30 to 40 percent faster than the general population.

An international study about the link between hearing loss and dementia has attracted a lot of attention in the last months.
Due to the growing interest and concerns of some of our readers, Action on Hearing Loss Audiologist Specialist Vaitheki Maheswaran critiques the modern-day lookup on the topic.
According to a worldwide find out about in the Lancet, it is estimated that there had been 46·8 million people living with dementia international in 2015, which is likely to amplify to 131·5 million by way of 2050. 58% of people with dementia stay in low earnings and middle earnings countries.
It is expected that the numbers affected through dementia to double in high-income international locations. But extra than treble in low and middle-income countries through 2050.

Hearing Loss And Social Isolation
The third link between hearing loss and Alzheimers is social isolation. A study by The National Council on the Aging of 2,300 hearing impaired adults found that people with untreated hearing loss are more likely to experience loneliness, worry, depression, anxiety, and paranoiaand are less likely to join organized and casual social activities. When a person withdraws from life, their risk for dementia intensifies. In short, the less we stimulate our brains by interacting with other people, places, and thingsand the less we use our brains to hear and listenthe more quickly our brains decline, putting us at greater risk for dementia.
Hearing Loss: How Common Is It
Hearing loss is widespread it affects 10 million people in the UK while six million people have or could benefit from a hearing aid. As our society ages, this number is set to grow: current predictions are that by 2031 there will be more than 14.5 million people with hearing loss in the UK .
Age-related damage is the single biggest cause of hearing loss. Seventy-one per cent of people over the age of 70 have hearing loss . This means that older people are very likely to experience hearing loss alongside other long-term conditions such as dementia. Other causes of hearing loss include exposure to loud sounds, drugs that are harmful to the cochlea and/or hearing nerve, some infectious diseases and genetic predisposition.

What Are The Best Hearing Aids For 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.
Mayo Clinic Minute: How Hearing Affects Your Brain Health
If you find yourself having difficulty following conversations or issues with memory and thinking skills, you may want to get your hearing checked. Age-related hearing loss may be linked to an increased risk of cognitive decline. Several large studies have shown that people who have a degree of hearing loss, even in midlife, have an increased risk of developing dementia later in life.
Journalists: Broadcast-quality video is in the downloads at the end of this post. Please “Courtesy: Mayo Clinic News Network.” Read the script.
Dr. Ronald Petersen, a neurologist and director of the Mayo Clinic Alzheimer’s Disease Research Center, says the exact reason why there’s an increased risk is not known.
“It could be that there are actually effects on the brain. Some studies have been shown that if people have a hearing loss over many years, certain parts of the brain, in particular the temporal lobe involved in hearing, but also involved in language and memory, may actually be smaller,” says Dr. Petersen.
It also could be that hearing loss leads to social isolation, which can lead to an increased risk in dementia.
Dr. Petersen recommends getting your hearing assessed every two to three years, especially if you’re noticing signs that your hearing may be deteriorating. Signs that hearing loss may be evolving include difficulty hearing conversations, especially in crowded rooms, and asking others to repeat themselves frequently.

Untreated hearing loss increases the risk for dementia . Adults with hearing loss have a faster rate of cognitive decline that adults with normal hearing . Hearing loss demands extra cognitive resources, which limits the cognitive resources that are available for memory and thinking. There are also documented changes in the brain as a result of hearing loss these changes are thought to impact cognition over time. Additionally, hearing loss can lead to a decrease in social engagement , which is a known risk factor of dementia. Although hearing loss does not cause dementia, it does place people at risk for developing dementia a supportive reason that hearing loss should not be ignored.
Many communication difficulties related to hearing loss can cross-over with difficulties related to dementia. If adults are uncertain which dysfunction may be causing difficulties, it is recommended to seek evaluation from an audiologist and a physician. A primary care physician can help patients determine if a cognitive evaluation is necessary and refer to the correct specialist for testing.
What To Do After Knowing The Symptoms

There Are Ways To Reduce The Risk Of Dementia
The 2020 Report by The Lancet Commission entitled: Dementia Prevention, Intervention and Care was released on July 30th, 2020. The latest research states that 12 modifiable risk factors from childhood to late life could delay or prevent 40% of dementia cases. These lifestyle factors can be adjusted in order to reduce ones risk for developing dementia. The 12 modifiable risk factors are presented below:
Of these 12 risk factors, an untreated hearing loss in midlife remains the largest modifiable risk factor of dementia. Additionally, the risk of dementia varies based on level of hearing loss.
- Mild hearing loss doubles the risk of dementia
- Moderate hearing loss triples the risk of dementia
- Severe hearing impairment increases the risk of dementia of up to five times that of those who do not have hearing impairment
The recent study by the Lancet also cites that hearing loss might result in cognitive decline through reduced cognitive stimulation. The study further recommends the use of hearing aids in those with hearing loss, as a way to protect against cognitive decline.

Hearing Loss Linked To Accelerated Brain Tissue Loss
Although the intelligence becomes smaller with age, the shrinkage looks to be fast-tracked in older adults with hearing loss, in accordance with the effects of a study by way of researchers from Johns Hopkins and the National Institute on Aging.
The findings add to a developing listing of health penalties related to hearing loss, which includes an extended chance of dementia, falls, hospitalizations, and diminished bodily and intellectual health.
When hearing loss occurs, areas of the brain dedicated to other senses such as vision or touch will definitely take over the areas of the brain which commonly process hearing.
Its a phenomenon called cross-modal cortical reorganization, which is reflective of the brains tendency to compensate for the loss of other senses.
Essentially, the brain adapts to a loss via rewiring itself. It is a sort of makeover, however one that can have a severely dangerous effect on cognition. Even early degrees of hearing loss can lead to cognitive decline.

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.

Hearing Loss Linked To Alzheimers Diseasewhats The Connection
Studies suggest that hearing loss causes brain changes that raise the risk for dementia. Brain atropy When the hearing section of the brain becomes less active because it is not stimulated by everyday sounds, due to hearing loss, it causes changes in brain structure, and thus brain function. Atrophy occurs more quickly in people with hearing loss could be the first link between hearing loss and cognitive decline.Studies show that the brains of people with hearing loss shrinkor atrophymore quickly than the brains of people with normal hearing.Brain overload An overwhelmed brain creates the second link between hearing loss and dementia. When it is difficult to hear, the brain must work overtime just to understand what people are saying. Straining to hear all day, every day, depletes a persons mental energy and steals brain power needed for other crucial functions like remembering, thinking, and acting. This can further set the stage for cognitive decline including Alzheimers disease and dementia.
