Better Hearing for Coastal kids

"Better Hearing for coastal kids", Jervis Bay Hearing Centre's principal Audiologist, Alison Chiam told the Audiology Australia's National Conference in Sydney today.  

80% of children will suffer at least 1 episode of Otitis Media by the time they reach school and 60% of these children will have an associated hearing loss.  Ms Chiam challenged the existing protocol of watching and waiting for the hearing loss to spontaneously resolve or treat the hearing loss surgically with insertion of grommets.  She has shown a more active approach may get better results.  She has been trialling Eustachian Tube exercises which show startling improvements.  83% of children showed a return to normal hearing in both ears over a 6 week period.   

Ms Chiam, says that early development is vital in kids.80% of children will suffer at least 1 episode of Otitis Media by the time they reach school and 60% of these children will have an associated hearing loss.  Ms Chiam challenged the existing protocol of watching and waiting for the hearing loss to spontaneously resolve or treat the hearing loss surgically with insertion of grommets.  She has shown a more active approach may get better results.  She has been trialling Eustachian Tube exercises which show startling improvements.  83% of children showed a return to normal hearing in both ears over a 6 week period.   .  Unfortunately, it is most common during a child's early learning years.  Hearing well is particularly important for development of language and continuing education.   Prolonged hearing loss can have impacts on a childs ability to process words and separate out different sounds.  So, its important to identify it quickly and help it to resolve as fast as we can.

Adding a non surgical option to our current methods helps kids to manage their own hearing loss at home as well as to continue a positive relationship with water.  When a child has grommets inserted we instruct them to keep their ears dry and to guard against water in their ears.  Our kids and families live by the beach.  Its important that we recognise how important the water is in the life of our kids and parents.  It was when one mother said to me, "I feel anxious when any of my kids are near the water." that I was moved to find another option and to do the research.   Before that, I didn't realise how much pressure open water puts on parents and families.  We are told that it only takes a few seconds for a kid to drown, and this is echoed in the WHO 2016 statistics, "Every year, 30 kids under the age of 5 drown in Australia alone".

In actual fact when I investigated at a deeper level, i found our current protocols are based on results obtained from Indigenous children in central Australia.  However 83% of the Australian population live within 50Km of the coastline and only 3% of our population is Indigenous.  Kids living on the coast have services available to support them, as well as the risk open water poses to a child under 5.  A more active approach could also reduce the need for surgical intervention, reduce the time a child is disadvantaged by a hearing loss for better learning and development outcomes and empower parents and families with a more patient centred care model.

Poor Hearing Could Lead To Poor Memory

17/5/2018

New research has uncovered an increased risk of mild cognitive impairment among individuals with a form of hearing impairment called central hearing loss. The findings suggest that this form of hearing loss may have a neurodegeneration-related mechanism at its root.

The National Institutes of Health (NIH) estimate that 15 percent of the adult population of the United States have a form of hearing loss.

Age is a significant risk factor for hearing loss. In fact, a quarter of U.S. seniors aged between 65 and 74, as well as half of those aged over 75, have a disabling form of hearing loss. Worldwide, a third of seniors have a disabling form of hearing loss.

A new study — led by Rodolfo Sardone, of the NIH and University of Bari in Italy — examines the link between a form of age-related hearing loss and the risk of developing mild cognitive impairment (MCI).
MCI is a type of cognitive decline that although noticeable is not significant enough to interfere with daily activities.

Research shows that between 15 and 20 percent of those aged 65 and above are likely to have MCI, which is also a risk factor for Alzheimer's disease.

The new study looked at both peripheral and central hearing loss. The former is due to problems in the inner ear and hearing nerves, while the latter affects the brain's sound processing abilities.

Sardone and his colleagues examined more than 1,600 people who participated in the Great Age Study, and the researchers' findings will be presented at the American Academy of Neurology's 70th annual meeting, due to be held in Los Angeles, CA, in April.


Hearing Loss May Double The Risk Of MCI

Sardone and colleagues had access to data on 1,604 participants in the Great Age Study, who were 75 years old, on average.

The participants were asked to undertake a series of hearing tests and have both their memory and reasoning tested.

Almost 26 percent of the study participants had peripheral hearing loss, and 12 percent had central hearing loss. Around 33 percent of the participants received a diagnosis of MCI, which was given using the well established
Petersen criteria.

Overall, people with central hearing loss were two times more likely to develop MCI compared with people whose hearing was intact.

More specifically, of the 192 people who had central hearing loss, 144 also had MCI. This amounts to 75 percent. By comparison, of the 609 people whose hearing was intact, 365 people had MCI, which amounts to 60 percent.

"These preliminary results suggest that central hearing loss may share the same progressive loss of functioning in brain cells that occurs in cognitive decline, rather than the sensory deprivation that happens with peripheral hearing loss." - Says Sardone

"It's a problem with perception," he adds. As the study authors note in their paper, "No previous study has investigated speech discrimination and separate[d] the auditory perception from [the] auditory function."

"Tests of hearing perception," says Sardone, "should be given to people who are older than 65 and also to people with cognitive impairment."

But he also cautions that the study does not prove causality — that is, it does not demonstrate that hearing loss leads to memory loss. Rather, the research merely points to a link between the two.

When Sound Becomes Pain

"It began with not a sound, but with pressure.  A great pulse or force that pushed him backwards away from the oven and into the kitchen bench...Later he would learn that two commercial spray cans of oil that had fallen behind the stove had exploded in the heat" 
"Then his boss was looming, her face close to his, her mouth moving but nothing coming out, no words, no sounds.  And still the enormous pressure, now pushing against his ears, as if he were underwater.  And a terrible inexplicable shrieking that he finally realised was coming from inside his own head."


Acoustic Shock Disorder can be triggered initially by a wide range of sounds such as, a starter pistol; a threatening voice at close range during an assault; metal hammering on metal; loud machinery; an unexpected blow to the ear or head; glass crashing; a public toilet hand dryer.  While critically Westcott says the volume of the noise is a factor, the common link is that the sounds are unexpected and startling.  Another is the presence of TTTS (Tonic Tensor Tympani Syndrome - a startle reflex)

Oticon OPN Designed With 'Brain First' Approach

15/5/2018

Keeping your brain fit so that you can stay sharp, engage socially, and participate in professional or volunteer activities is a concept that appeals to a wide range of age groups, from young adults to baby boomers and beyond.  While many strategies for “healthy aging” exist, the newest evidence points to the important role of hearing health in maintaining quality of life long-term, according to a press release from Oticon, a Denmark-based hearing aid manufacturer.
Keeping Your Brain Fit
If you are among the 75% of people with hearing loss who could benefit from hearing aids but are reluctant to take action, the newest research findings may be the powerful motivator you need.  A study1 published in the Journal of the American Geriatrics Society found no difference in the rate of cognitive decline between people with no reported hearing loss and people with hearing loss who used hearing aids. In fact, people with hearing loss who wear hearing aids had the same risk for age-related cognitive decline as people without hearing loss.  When you actively use hearing aids, you are more likely to stay socially engaged, one of the primary ways to stimulate your brain, according to Oticon.
A “Brain First” Approach
Today’s advanced hearing aid technology takes into consideration the critical role that the brain plays in hearing. For almost 20 years, Oticon researchers at the Eriksholm Research Centre have focused on a “brain first” approach that processes the speech signal so it is presented to the brain as clearly and accurately as possible. With better sound information, the brain doesn’t have to work as hard to understand what is being said, said Oticon in the release.
Oticon hearing instruments with BrainHearing™ are an example of the “brain first” approach. By giving the brain a clearer, more accurate sound signal, Oticon hearing aids with BrainHearing™ are designed to make it easier to understand conversation—even in noise.

Easy on the Brain, Easy Connectivity

The Oticon Opn is designed to improve a user’s ability to understand speech by up to 30%2, so a user doesn’t have to work as hard to understand, leaving more mental energy to remember what you hear, according to Oticon. Opn is designed to process sound at extreme speed to remove distracting noise, even between words and makes it easier to follow conversation, even in environments with multiple people speaking, such as crowded restaurants.

The newest BrainHearing solution also connects directly to compatible mobile phones and other external devices so users can stay connected on the go; audio can be streamed directly to your hearing aids. Opn is also “the world’s first hearing device that is connected to the Internet via the IFTTT network,” a web service that automates other web-based functions, according to the company’s press release. You can use Opn hearing aids with a growing number of IFTTT-compatible products and services from wake-up notices and sports reports to practical considerations such as low battery alerts and connections to smart home devices.

Refocusing the Brain
There are many ways to take control of your tinnitus and reduce its impact on your life. A hearing care professional can help you manage your symptoms through education, counseling, and sound therapy. Oticon Opn hearing aids with built-in Tinnitus SoundSupport™ are designed to direct the user’s focus away from tinnitus by playing a range of adjustable relief sounds like white noise and ocean-like sounds.
Hearing Care is Health Care™
When it comes to healthy aging, it makes sense to take care of your hearing health, just as you care about the rest of your health. The World Health Organization estimates that more than 360 million people worldwide suffer from hearing loss.3 Many of them aren’t aware of it or are putting off treatment. If you’re one of them, you owe it to yourself to visit a hearing care professional for a hearing evaluation. Your future as an active, engaged, healthy person could depend on it.
