We all want to stay mentally sharp as we age, which is why brain training games have become so popular. They promise to preserve our mental function and, more importantly, our memories.
But is that what’s actually happening? We won’t get into the debate here, but suffice to say that the latest research isn’t promising for the brain training games, in that they failed a big scientific test.
With brain training games looking less promising, where can you turn? It turns out that the connection between memory and hearing is stronger than anyone initially thought. In fact, research continues to highlight the importance of healthy hearing to a healthy memory.
Let’s review how human memory works and how treating hearing loss is one of the best ways to give your memory a boost.
How Human Memory Works
Human memory is a complex, brain-wide process. There are no single areas of the brain we can point to as being the one location where memories are stored.
Memories are stored across the brain with electrical and chemical signals involving billions of neurons and trillions of connections between them. Needless to say, memory is not fully understood.
What we do know, however, is that the creation of memories occurs in three stages: encoding, storage, and retrieval.
The first stage, encoding, occurs when you pay attention to something in the environment. This helps you filter out unimportant information and focus on what’s important. Otherwise, if your brain were to store every stimulus you were exposed to, your memory would quickly fill to capacity.
The next stage is memory storage. Your short-term or working memory can hold about seven pieces of information for 20-30 seconds. You can expand this capacity through several techniques, such as chunking (breaking long strings of numbers into groups, for example) or by using mnemonic devices.
Information stored in short-term memory either fades away and is lost or becomes stored as long-term memory. The keys to moving information from short-term to long-term memory are attention, repetition, and association. Your memory of any piece of information will improve as you become:
- less distracted and more focused on the information you want to store.
- exposed to the information more frequently and for longer periods of time.
- able to associate the new information with information you already have.
The next stage is memory retrieval, where you can recall, at will, information stored in long-term memory. The better the information in encoded and stored, the easier it will be to recall.
How Growing Older Affects Memory
We should keep in mind that the brain has what is called plasticity, meaning it can change its structure in response to new stimuli. This can be both good and bad.
As we age, our brain does in fact change. It loses some cells, some connections between cells, and generally shrinks in size. These structural and chemical changes can impair our memory and general cognitive function as we grow older.
However, the plasticity of our brains also means that we can create new connections as we age, learning new things and strengthening our memories at the same time. In fact, studies have shown that exercise and mental stimulation can keep our brains sharp well into our 80s.
It’s really a lack of use that is the biggest culprit of memory decline as we age. That’s why keeping our minds active and learning new things is an essential part of healthy aging.
How Hearing Loss Affects Memory
What about hearing loss? Can hearing loss actually affect our memory?
Studies have shown that hearing loss can impact your memory, and it’s easy to see why. We’ve already seen that your ability to store information in long-term memory is dependent on your ability to pay attention.
So let’s say you’re having a conversation with someone. With hearing loss, two things are happening. One, you’re simply not able to hear part of what is being said, so your brain is never able to properly encode the information in the first place. Later, when you need to recall the information, you can’t.
Second, because you’re only hearing part of what is being said, you have to devote mental resources to trying to figure out meaning through context. In the struggle to understand meaning, most of the information is distorted or lost.
On top of it all, the brain has been shown to reorganize itself in those with hearing loss. With reduced sound stimulation, the part of the brain responsible for sound processing becomes weaker and the brain then recruits this area for other tasks.
Improve Your Memory, Schedule a Hearing Test
From the discussion so far, the solution to improving our memories as we age is clear. First, we need to keep our minds active and sharp, challenging ourselves and learning new things. A little physical exercise can go a long way as well.
Second, and just as important, is taking the steps to improve our hearing. Enhancing sound stimulation with hearing aids can help us to better encode and remember information, especially during conversations. And, the enhanced sound stimulation to the parts of the brain responsible for sound processing ensures that these areas stay strong.
So forget the brain games—learn something new that you have an interest in and schedule your hearing test to ensure that your hearing is the best it can be.
Tinnitus can be an unbelievably frustrating condition to deal with for a wide variety of reasons. First and foremost, it’s extremely subjective experience. What we mean by that, is you can’t really show anybody what the unending ringing of tinnitus sounds like, how loud the constant barrage of noise is, or how much of a bother tinnitus can be.
Second, there still isn’t an objective way to measure the intensity of one’s tinnitus. You can’t, for example, drive to your doctor’s office, have tests ran, get some blood drawn, and get diagnosed with the condition.
Lastly, and most frustratingly, the medical community still doesn’t have an exact understanding of how tinnitus works. As a direct result, our understanding of the potential causes and possible array of treatment options remains at a less than ideal level.
This can all amount to an extremely frustrating situation, of course, but those affected should not feel hopeless. As an encouraging matter of fact, despite the many reasons for frustration, many people go on to show significant improvements in their tinnitus symptoms when paired with the right treatment plan.
Throughout this article, we will be discussing one tinnitus treatment option in particular, known as Tinnitus Retraining Therapy (TRT). TRT has proven to be particularly effective and is quickly becoming one of the most trusted and reliable tinnitus treatment options available today. However, to truly understand how Tinnitus Retraining Therapy works, we will first have to go over the two parts of tinnitus. Read more about it below.
The Two Parts of Tinnitus
Tinnitus is the perception of sound when no external sound source is present. We can break tinnitus down into two parts:
- The actual sound – usually perceived as a ringing sound, but can also be perceived as a buzzing, hissing, whistling, swooshing, or clicking sound.
- The emotional reaction – the perception of the loudness and character of the sound and its disruption to everyday life.
The effective treatment of tinnitus therefore requires addressing both parts, which is the underlying rationale of Tinnitus Retraining Therapy.
Sound therapy is the use of external sound to “mask” the internal sound of tinnitus. This mitigates tinnitus on a number of levels.
First, the external sound can partially or completely cover the tinnitus sounds, and can also divert the patient’s attention, while the sound is being played. This can provide immediate relief.
Second, sound therapy can result in what is called “habituation,” where the brain is trained over time to reclassify the tinnitus as an unimportant sound that should be ignored.
Third, the use of specialized sound minimizes the hyperactivity in the brain thought to be the underlying mechanism of tinnitus. This is called “neuromodulation.”
Sound therapy therefore has both short-term and long-term benefits, and works on multiple levels to mitigate the severity of symptoms. Sound therapy can be delivered through special sound masking devices, headphones, and even hearing aids.
While any sound can theoretically provide the masking effect, specialized medical-grade devices deliver customized sounds or music programmed to match the characteristics of the patient’s tinnitus. Your hearing care professional can help you select the right device and sound.
Cognitive Behavioral Therapy
In addition to sound therapy, TRT also employs behavioral therapies that address the second, emotional component of tinnitus. In ways, this is the more critical component, as tinnitus can trigger strong emotional reactions like anxiety, depression, and anger.
That’s good news because it means that you can learn various techniques to reduce the anxiety caused by tinnitus (which itself can make the tinnitus worse). And that’s why behavioral therapy has been so effective—in fact, a 2010 meta-analysis of eight research studies showed significant improvement in depression and quality of life for patients that participated in the programs.
Behavioral therapy can be delivered one-on-one or in groups, from a clinic or over the phone or internet from the patient’s home. Therapy includes education, identifying tinnitus triggers, instituting healthy lifestyle choices to mitigate symptoms, and mindfulness-based stress reduction.
Take Action and Silence Your Tinnitus
Tinnitus Retraining Therapy is effective because it leads to habituation on both fronts, both in terms of the actual sound and in terms of the emotional and behavioral responses.
While there is no known cure for tinnitus, you can mitigate the symptoms with the right plan and some perseverance. As your tinnitus is masked and the brain is trained to ignore it, you’ll be able to better cope with the sounds and improve your quality of life.
Digital hearing aids are well on their way to representing the future of hearing impairment: many models come with remote controls that allow for adjustment of various settings, or omnidirectional microphones that pick up on the slightest sound from multiple directions. (more…)
The healthcare market is going through some rather extreme transformations in the context of where you can get care. For example, while you once needed a doctor and a script to get a hearing aid, now you can skip the consult and go directly to a big box store like Costco to get a device. While it is convenient, it presents a variety of problems and is a harmful practice for many different reasons. (more…)
One of the most devastating illnesses that a person can suffer from throughout their life is hearing loss. Not only does it present a great deal of functional problems, but it can also cause problems in other areas of your health. (more…)
When you think about diabetes, you may not immediately think of hearing loss. Truth is, the two conditions are closely related. According to the American Diabetes Association, diabetes and hearing loss are two of the top health concerns in this country. (more…)
