How Does Tinnitus Affect The Brain

How Tinnitus Impacts Daily Life

Tinnitus can have many different effects on a persons life. Although no two people may complain of exactly the same problem, the main categories of impact are difficulty concentrating, emotional reactions, and disrupted sleep. Usually, effects of tinnitus include emotional reactions. For example, difficulty concentrating can lead to frustration and anger.

Therapeutic Supplements To Calm The Brain

Dr. Emmons lists the following supplements in the order in which he recommends them. He considers these supplements medicinal and discusses the function and proper dosage of each.

1 L-theanine is an amino acid found in high concentrations in green tea. You cannot drink enough green tea to get a therapeutic dosage but it is available in green tea extract or labeled as L-theanine.

L-theanine changes brain waves as measured on an EEG , promoting the relaxed and alert state associated with alpha waves. It can sharpen mental focus and calm anxiety at the same time.

L-theanine is one of the most common treatments recommended by Dr. Emmons for anxiety. It is usually taken in doses from 50 to 200 mg once or twice daily. For severe anxiety it can be taken up to four times daily. It is not habit forming and there are no known drug interactions. However, he recommends talking to your doctor first if you are on any medications.

2 L-tryptophan or 5-HTP are precursors to serotonin and help to elevate serotonin levels in the brain.

5-HTP can be taken by itself in doses starting at 50 mg per day, increasing every few days as required. Most people do well with 100-150 mg daily but can go to 300 mg if needed. It is normally best to take in divided doses two or three times throughout the day. If it becomes sedating, it may all be taken at night. It is best absorbed if taken one half hour before meals. That also helps to reduce carbohydrate cravings.

Looking For The Truth In Tinnitus

David Baguley, professor in hearing science at the University of Nottingham and former president of the British Tinnitus Association, recently co-authored a review of why a cure for tinnitus is still missing. Baguley sees stochastic resonance as one model among several. I think there is a consensus that tinnitus is a noise within the system. Stochastic resonance is one way in which noise can be boosted over signal. There are a number of proposals for mechanisms, and they are not mutually exclusive. In fact, they are under urgent investigations. One problem is that animal models dont really represent the human experience. But understanding the mechanism of tinnitus is important.

Baguley says that tinnitus will benefit from a more personalized approached. I use the term ignition site. We need to look at where the ignition site is in a patient and I am sure that it is varied in different people. Im sure that once we can subtype tinnitus, we can look at influencing the ignition site.

Schulze agrees that models of tinnitus need to be seen in context. I think that all models contribute a piece of the truth. Our model helps to explain part of the phenomenon, particularly the speed at which tinnitus can arise.

How Does Tinnitus Start

It varies, but for some people it might arise gradually from long-term noise exposurelike the factory experience. For others, it could be an explosion or a car accident; all of the sudden, the tinnitus is just there. The biggest challenges often occur at the beginningpeople want to know, What is this? Is there something else wrong? Is this going to be with me forever? Or I dont have any control over this! These are normal reactions.

Evaluate And Treat Underlying Problems

If you develop tinnitus, it’s important to see your clinician. She or he will take a medical history, give you a physical examination, and do a series of tests to try to find the source of the problem. She or he will also ask you to describe the noise you’re hearing and the times and places in which you hear it. Your clinician will review your medical history, your current and past exposure to noise, and any medications or supplements you’re taking. Tinnitus can be a side effect of many medications, especially when taken at higher doses .

Musculoskeletal factors jaw clenching,;tooth grinding, prior injury, or muscle tension in the neck sometimes make tinnitus more noticeable, so your clinician may ask you to tighten muscles or move the jaw or neck in certain ways to see if the sound changes. If tight muscles are part of the problem, massage therapy may help relieve it.

Tinnitus that’s continuous, steady, and high-pitched generally indicates a problem in the auditory system and requires hearing tests conducted by an audiologist. Pulsatile tinnitus calls for a medical evaluation, especially if the noise is frequent or constant. MRI or CT imaging may be needed to check for a tumor or blood vessel abnormality.

If you’re often exposed to loud noises at work or at home, it’s important to reduce the risk of hearing loss by using protectors such as earplugs or earmuff-like or custom-fitted devices.

What If One Of The Sense Organs Is Damaged

Imagine what will happen if one of these sense organs gets damaged. Would we be able to enjoy the full experience of the world around us? Probably not, because now our brain would be missing the important information from this sense organ. We will be explaining this in detail by using the ear as an example. If our ears are damaged and we are not hearing well, this will have two consequences. First of all, the brain will be missing the information from the ears. This is called hearing loss. Second, the brain tries to fill the gap created by this hearing loss. As a result of this, a person with hearing loss might start hearing a sound that others cant hear. This sound is called tinnitus. We will explain both hearing loss and tinnitus in detail in this article.

Tinnitus The Troublemaker In Your Brain

The music is jubilant and lively. But suddenly, a shrill, high note on the violin begins to pull at the nerves: In his string quartet, From my Life, the Czech composer Bedich Smetana translated the ringing noise in his ears into music. The composer describes his experience in a letter: But the greatest torture is caused me by the almost continuous internal noise which goes on in my head and sometimes rises to a thunderous crashing.

Like Smetana, more than 50 million people in the United States experience tinnitus: a sound they can hear when no actual sound is present. The name tinnitus comes from Latin and describes the ringing sound described by many patients. 20 million people are estimated to struggle with a chronic form, while 2 million suffer from an extreme form of tinnitus. So far, there is no cure that makes the sound disappear in all forms of tinnitus; most therapies aim to help patients cope better with the constant sound, which can be so uncomfortable that tinnitus sufferers have been driven to suicide. But a new model suggests that tinnitus is the side effect of a mechanism that improves hearing, and points towards potential new ways for treating tinnitus.

Hearing Loss Tinnitus And Brain Change

By Barry KeateBarry Keate, has lived with tinnitus over 40 years and has published 150+ research articles on numerous aspects of tinnitus. He is an expert on the condition and a well-known advocate for those with tinnitus.

Weve all heard stories of people who have lost their sight but then experienced other sensory improvements such as increased hearing levels. This is evidence that our brain is capable of re-wiring itself to compensate for changes in external input. Studies have shown the brains of blind people to be significantly changed neurologically, compared to sighted people, to deal with the situation.

Now there is evidence that hearing loss creates its own neuronal changes in the brain that can be measured. The study, from the University of Illinois, shows that hearing loss causes long-term changes in the brain structure of the estimated 50 million people in the US who suffer from it. Interestingly, those who have hearing loss and tinnitus do not seem to suffer the same changes as those with hearing loss alone.

Researchers used two different, high resolution MRI techniques to measure both gray and white brain matter changes related to tinnitus and hearing loss and in order to dissociate them from changes due only to hearing loss.

They employed three groups of subjects to test the separation; those with hearing loss but no tinnitus, those with hearing loss and tinnitus, and a control group of those with normal hearing and no tinnitus.

What Actually Happens To The Brain In Someone Who Is Suffering From Tinnitus

A new study revealed an interesting connection between brain activity and tinnitus.It showed that defects that occur within the brain can cause the person to experience tinnitus that may last longer than usual and be more pronounced or noticeable.

Control pathways to the Brain Compromised

The researchers found that after the brain was subjected to an injury such as exposure to loud noise for instance, the control pathways was affected.

What actually happens is that the brain looses the ability to control the pathways that are responsible for regulating noise and pain signals, which in turn leads the person to perceive noises as well as experience pain.

Brain reprogramming.

So to compensate for this loss,the brain re-programs itself, and it is this reprogramming that gives ;the person these; phantom, noises which is;characteristic of tinnitus.

Why is it called phantom sensations?. Because these noises are subjective and can only heard by the person and therefore classified as un-real.

Professor Rauschecker of the Director of Laboratory for Integrative Neuroscience and Cognition at the GUMC , concluded that these perceptions are indeed real as;a result of the brain unable to switch off the sensations to a low-enough degree.

He further added that, though the noise and associated pain are extraordinarily common, no treatment exists yet to get to the root of these disorders.

Tinnitus Mapped Inside Human Brain

For the first time, signals relating to the constant ringing noise of tinnitus have been mapped across the brain of a patient undergoing surgery.

In this rare case, a man with tinnitus was being monitored to trace his epileptic seizures, with 164 electrodes placed directly onto his brain.

Researchers compared brain activity when his tinnitus was loud, with periods when it was quiet.

They spotted differences spread over a surprisingly wide set of brain areas.

The study appears in the journal Current Biology.

Tinnitus, the constant presence of phantom sounds, affects around 10% of adults in the UK; for 1% it is severe enough to affect their quality of life. Often it takes the form of a ringing sound, but it can be anything from a roar to a hiss.

In many cases it begins with partial hearing loss, sometimes due to loud noise wearing out the hair cells that convert sound waves into neural signals, inside the inner ear. The brain adjusts to that loss of input by boosting certain types of activity, creating the impression of a noise that nobody else can hear.

What Are The Effects Of Tinnitus On The Brain

The brain is a constantly adapting system. As we age and have new experiences, our brain develops new neural pathways and changes accordingly. However, some changes aren’t for the better, and tinnitus can cause detrimental effects on your health.

Tinnitus

Like many other conditions, tinnitus can cause changes to your brain. Many of these effects are caused by your brain’s malleability. Because tinnitus is complicating how you live your life, your brain adapts to make things easier on you. While this can lessen the negative aspects of having tinnitus, not all of these changes are healthy for you. Some of your brain’s efforts are helpful, while others might cause more intense problems.

Why Does Tinnitus Make You Feel Tired And Unconcentrated

Using MRI scans of the participants, the study found that tinnitus was in a region of the brain called the precuneus. This part of the brain is connected to two inversely related networks in the brain called the dorsal attention network and the default mode network:

• The dorsal attention network: This part of the brain is active when something holds a persons attention
• The default mode network: This is the background functions of the brain when the person is at rest and not thinking of anything in particular

In people with chronic tinnitus, the brain region the precuneus was more combined to the dorsal mode network and less combined to the default mode network. This means that people with tinnitus are not truly at rest when resting, which explains why many feel tired. Besides, people with chronic tinnitus may experience concentration issues because their attention may be engaged more with their tinnitus than necessary, and that may decrease their attention to other things.

The Links Between Hearing And Health

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.;

Vicious Cycle Of The Stress Response

Normally, when a dangerous situation is resolved, our parasympathetic nervous system is activated. The opposite of the fight-or-flight response, it’s known as “rest-and-digest.”

But with tinnitus, you can get stuck in a state of fight or flight that never really ends because the sound doesnt just magically disappear.

With tinnitus, you can get stuck in a state of fight or flight that never really ends because the sound doesnt just magically disappear.

Unfortunately, it often gets worse, because the brain starts to associate the emotional fall-out of an experience like thisthe anxiety, panic, anger, frustration, anguish, depression, and stresswith the sound of your tinnitus.

These negative emotions are snowballed into the reaction, and become are part of the reaction, leaving you with something much worse than a simple fight-or-flight stress response.

Some people do habituate naturally and find their tinnitus bothers them less and less over time, but not everyone. For many sufferers, it just gets more and more difficult, and starts to affect every single aspect of their quality of life.

And as the anxiety, panic, and stress increase, the tinnitus often seems louder and spikes more frequently, which in turn makes sleep difficult, which affects focus and productivity, and so on.

You get trapped in a vicious cycle. But the cycle can be broken.

Hearing Aid Myths That Hold You Back

Can hearing aids reduce these risks? Lin hopes to find out in a new study, still in the planning stages. These studies have never been done before, he notes. What we do know is that theres no downside to using hearing aids. They help most people who try them. And in those people, they can make all the difference in the worldallowing people to reengage with friends and family and to be more involved again.

Although nearly 27 million Americans age 50 and older have hearing loss, only one in seven uses a hearing aid. If you think your hearing has diminished, its worth making an appointment with an audiologist for a hearing check, Lin says. If you have hearing loss, dont let the following myths keep you from getting help.

White Matter Consequences Of Hearing Loss

Hearing loss was accounted for by , who in addition to grey matter volumes assessed the integrity of white matter tracts. They found profound changes in white matter tracts near the auditory cortex in subjects with hearing loss. More specifically, their analyses revealed reduced fractional anisotropy in both of their hearing loss groups in the right anterior thalamic radiation, inferior fronto-occipital fasciculus, and inferior longitudinal fasciculus, compared to controls. According to the authors, these plastic changes could reflect either sensory deprivation or compensatory mechanisms causing damage to white matter tracts or expansion of other fibres into these regions. Therefore the tract-based morphometry results of Husain and colleagues are in line with their VBM results in the sense that hearing loss rather than tinnitus affects brain morphology.

Ringing In Ears Keeps Brain More At Attention Less At Rest Study Finds

Date:

University of Illinois at Urbana-Champaign

Summary:

Tinnitus, a chronic ringing or buzzing in the ears, has eluded medical treatment and scientific understanding. A new study found that chronic tinnitus is associated with changes in certain networks in the brain, and furthermore, those changes cause the brain to stay more at attention and less at rest. The finding provides patients with validation of their experiences and hope for future treatment options.

“Tinnitus is invisible. It cannot be measured by any device we have, the way we can measure diabetes or hypertension,” said study leader Fatima Husain, a professor of speech and hearing science at the University of Illinois. “So you can have this constant sound in your head, but nobody else can hear it and they may not believe you. They may think it’s all in your imagination. Medically, we can only manage some symptoms, not cure it, because we don’t understand what’s causing it.”
