Most Common Cause of Tinnitus: Reduced 28%-39% – long-term

tonight us that's that ringing buzzing or humming sound you hear when there's nothing outside to make that noise everybody has tinnitus now and then maybe for a second or two maybe five seconds some people have it for a long time not just minutes or hours but days weeks months years decades well there's hope for quieter days ahead we know why a person developed tinnitus and we know how to reduce actual tinnitus not just cover it up or get used to it most tinnitus is caused by brain remodeling that occurs after partial hearing loss we can see this brain remodeling in images with functional MRI that shows blood flow in people with tinnitus and without tinnitus and it looks different we also see before and after treatment and it looks different this presentation will illustrate what happens in the brain to cause tinnitus and how brain remodeling can be used to reorganize the nerve connections so the tinnitus is reduced significantly and many people we do not understand it perfectly yet but this explanation seems to be very close to reality and is supported by successful treatment sound that we normally hear comes from outside the year but it's not sound until hear it it's merely the vibration of air molecules air vibrates hair cells in the inner ear cochlea the hair cells are arranged in order tone frequency like piano keys so a particular speed of air vibration will vibrate a specific hair cell like an electric piano the hair cell changes the vibration into an electrical signal we still do not hear it until it travels as electrical signals to our brain from the inner ear cochlea the signal travels to the brainstem then up to both sides of the brain this is the same path of sound seen from the side view in the brain the nerve paths are also organized like electric piano keys tones are lined up next to each other from high to low each tone has a specific spot in the brain where it's perceived high notes are on the inside of the temporal lobe here that's normal hearing but how does tinnitus develop like a piano losing some of its keys damage occurs to the hearing machinery usually hair cells in the cochlea now portion to the sound from the environment cannot be signaled to the in the brain the specific spot that normally would perceive that specific tone or range of tones now here is less or nothing the vibration never travels beyond the inner ear cochlea it is as if the vibration of the air never happened if the neurons in the brain are not stimulated naturally they begin to get unhealthy and fire spontaneously you perceive this as tinnitus ringing buzzing etc that's nice information but to understand why you must have more details to help you understand consider the similarities between a muscle and a neuron healthy neurons provide normal hearing in rare if any tinnitus muscles need exercise and nourishment to stay healthy so two neurons a neuron needs to be regularly stimulated fired and nourished to stay healthy so muscles exercise helps keep it strong neuron stimulation helps keep it healthy healthy neurons provide normal hearing and rare tinnitus muscles get exercise by lifting and nourishment through blood to stay healthy a neuron is fired by having its receptor exposed to stimulus like vibration in the cochlea and nourished through the blood with oxygen and glucose to stay healthy good neuron stimulation and normal hearing the air vibrates vibrations enter the cochlea where specific electric piano keys so to speak but your nerve endings are stimulated that's normal healing normal hearing and healthy neurons lack of stimulation to some neurons causes partial hearing loss or unhealthy neurons being unable to exercise a muscle results in muscle wasting similarly losing ability to hear from damage to the cochlea means the neurons between the ear and the brain cannot be fired unhealthy neurons provide imperfect hearing and occasional tinnitus muscles that are not nourished and exercised get weaker so two neurons but they also get unhealthy an unhealthy neuron has two stages of poor health Stage one and needs extra stimulation to fire of course if the cochlear hair cells the nerve endings which are really nerve beginnings are dead or severely damaged you cannot provide extra stimulation through the normal channels of hearing partial hearing loss with this you have some air vibration and the working neurons are stimulated which is like the working Keys on electric piano the nerve endings but you don't hear some sound because the unworking neurons didn't communicate unhealthy neurons provide imperfect hearing and occasional tinnitus an unhealthy neuron has two stages of poor health the second stage it fires spontaneously that would be getting extra stimulation but if it doesn't get it it will fire spontaneously very unhealthy neurons partial hearing loss and frequent tinnitus muscles can get so malnourished or tired that they twitch or cramp so two neurons but they fire spontaneously so here we have muscle fatigue or cramping and neuron spontaneously firing whatever the brain normally perceives with that neuron whether it's taste smell sound tingling pain light etc or be perceived but not normally it may be at the wrong time volume or character skip this page if too many details confuse you the reason you're on fire spontaneously is even more complex but it will give you the crash course here in about 50 words neuron simulation causes gene response it's abbreviated I AG for immediate early gene response gene response causes production proteins and proteins because of their negative charge and involvement in ATP or energy production keep the cell at a charge that is far away from threshold or firing thus lack of stimulation results in neurons firing to easily respond hainsley because they cannot stay away from threshold firing unhealthy neurons and tinnitus you hear sound whether or not there is any outside of vibration so here's normal sound and air vibration simulating the working neurons they all stay healthy here the correct sound but that Center neuron not normally stimulated grows unhealthy and begins to fire spontaneously you hear sound that's not really there so that explains the cause of tinnitus how can tinnitus be diminished though in the past there were two approaches restore hearing distract with other noise first will briefly describe how those two work then we'll introduce the newest approach restore hearing with a cochlear implant if the procedure is successful it can restore health and function to the neurons this reduces the tinnitus here's the cochlear implant ear sound and it communicates to all these neurons neurons are normally stimulated become more healthy cochlear implants an amazing invention involve a skilled surgery and children have never heard the improvements can be amazing for brain development in adults there are several issues to consider or beyond the scope of this presentation now there's distraction with other noise with the right extra noise you become less aware of tinnitus this helps many people sleep but there are no lasting improvements distracting with other noise is an Old Faithful and helping people tolerate their tinnitus unfortunately it doesn't address the root of the problem and it's just plain irritating for some people distraction is not a bad thing just doesn't improve the condition and now introducing the newest approach auditory discrimination therapy actually we've even taken it a step further we now have circumscription auditory discrimination therapy that difference may be critical for your recovery but you don't need to remember for now continue to see how it works auditory discrimination therapy maximize functional neuron pathways to restore neuron health you begin by carefully listening to tones near your dysfunctional neurons so you're carefully specifically simulating neurons around your unhealthy one you train 30 minutes a day for 30 days carefully learning to distinguish between one sound and another over time neurons grow the result is that the neurons decrease their spontaneous firing recruited four useful brain function and are kept healthy there is hope the research using this newest technique called auditory discrimination therapy has proven results of reducing the tinnitus based on the tinnitus handicap inventory about 50% of people by 27% that's not perfect but it is good and without surgery or any more than 30 minutes per day for 30 days we're still working on the research what does it take to maintain that long term it will probably take some effort but not as much as it did get you that place we have even higher hopes there's more hope with our understanding of functional neurology and natural synergistic approaches we've improved on the previous techniques significantly you put improved in quotations because we haven't proven this result yet with research that's what our present clinical trials are about what our expectations are high don't let sore muscles stop your workout previous research showed that a moderate percentage of disciplines had their tinnitus get worse before it got better we've not seen this in our research yet but it makes sense remember the slide where the unhealthy non began to get stimulation tinnitus may get a little worse before it gets better but remember when you start to work out your muscles may get a little sore before you start getting strong there is hope brain is amazing this is an amazing process and it makes a limb making a little amount of effort to accomplish after a couple days this will be a breeze and you'll be well on your way to quieter days I wish you well you
