WT Prof’s Tinnitus Research Rings True March 29, 2011 by Emma Filed under Featured, Tinnitus News A professor at West Texas A&M University may have discovered a way to help permanently decrease or remove tinnitus, a condition that causes a constant, and often irritating, ringing in the ears. The American Tinnitus Association reports that tinnitus affects up to 50 million Americans. The causes of the condition vary but include hearing loss, exposure to loud noises, serious illnesses and consumption of substances such as nicotine, caffeine and medicine. Leslie Dalton, a professor at WT’s speech and hearing clinic, has spent the past 12 years developing tinnitus treatment mostly delivered through the use of a chip, software and large headphones. The chip sends a quiet and pre-programmed sound to the headphones, changing the channels sound takes to reach the brain. Dalton, in his third year at WT, likens the process to reorganizing roads to change the way a vehicle reaches a destination. Whatever conditions lead to tinnitus affect the brain’s normal functions, causing the ringing sound, he said. “It causes the brain to reprocess in the wrong place,” he said. “We return the hearing so that the normal part of the brain takes over.” Dalton has seen some success with his work. Gretchen Mercer, who took Dalton’s treatment a few times during the past year, said the method completely removed her tinnitus whenever she put on the headphones. “The first time I put on the headphones, my whole body just relaxed,” she said. “You hear nothing. It totally erases the tinnitus.” One of the goals with the tinnitus research is to create a prototype that can be distributed to local audiology clinics before the end of the summer, said Paige Brittain, owner of Headsets Inc., an Amarillo business that sells aviation and military headsets. About a year ago, Brittain and Dalton helped start up another company, Dichonics Inc., with plans to later manufacture personal devices that can deliver the sound treatment. “We will continue to improve the product,” Brittain said. “But right now, we’re just trying to put it together and put it in the hands of specialists.” While the treatment Dalton performs at WT provides no long-term fix for tinnitus, he said he thinks that giving patients daily access to a device at home would let them train their brains into ignoring the condition. “Once we get to nano-technology, we can turn into a kind of hearing aid,” he said. While millions of Americans suffer from tinnitus, many more do not report the condition, said Diana Wise-McPherson, an Amarillo audiologist. She said most of her patients suffer from the condition. “From past numbers I’ve heard, about half of the world’s population has some kind of head noise,” she said. “Now whether it bothers their life, that’s another thing.” Treatments to relieve tinnitus exist, but none of them decrease or remove the condition, she said. Existing treatments include acupuncture and massage therapy, she said. “People do all kinds of things, but there’s nothing scientifically proven on the market that alleviates tinnitus,” she said. Other treatments include masking the tinnitus with other sounds or sending electricity into the ear’s cochlea, Dalton said. “But the patient still hears something,” he said. Mercer said she developed tinnitus about two years after contracting the West Nile virus in 2004. The virus caused some hearing loss, she said. “In my experience, it can debilitating,” she said. “It can drive you insane. It’s a constant humming in your head. Sometimes, you can ignore it, but there are times when it’s just loud and it gets worse.” Source: Amarillo

WT-a prof Tinnitus Istraživanja prstenovi istinito Ožujak 29, 2011 prema Emma Varalica pod Istaknuti, Tinnitus Vijesti Profesor na West Texas&M University svibanj su otkrili način da se pomogne trajno smanjenje ili uklanjanje šuma, stanje koje uzrokuje konstantan, i često iritantan, zujanje u ušima. The American Association Tinnitus izvješća da je tinnitus utječe na do 50 milijuna Amerikanaca. Uzroci stanja razlikuju, ali su gubitak sluha, izlaganje na glasne zvukove, ozbiljne bolesti i potrošnja tvari kao što su nikotin, kofein i medicina. Leslie Dalton, profesor na ds govora i sluha klinici, je proveo posljednjih 12 godina u razvoju zujanje u ušima liječenje uglavnom se provode kroz korištenje čip, Softver i velike slušalice. Čip šalje miran i pre-programirane zvuk na slušalicama, mijenjanje kanala zvuka vodi do mozga. Dalton, u svojoj trećoj godini na WT, uspoređuje proces reorganiziranja cestama promijeniti način na vozilo dosegne odredište. Bez obzira na uvjete dovesti do tinitusa utječe na mozak normalno funkcionira, uzrokujući zvonjenje, , kazao je. “To uzrokuje mozga reprocess na krivom mjestu,” , kazao je. “Vraćamo sluh, tako da normalan dio mozga preuzima.” Dalton je vidio neki uspjeh sa svojim radom. Gretchen Mercer, tko je uzeo Daltonov liječenje nekoliko puta tijekom posljednjih godinu dana, , rekao je metoda potpuno uklonjen joj zujanje u ušima kad ona stavi na slušalicama. “Prvi put sam stavio na slušalicama, cijelo moje tijelo samo opušteno,” , rekla je ona. “Možete čuti ništa. To je potpuno briše zujanje u ušima.” Jedan od ciljeva s tinnitus istraživanja je stvoriti prototip koji se može distribuirati lokalne audiologija klinike prije kraja ljeta, Paige je rekao Brittain, vlasnik Slušalice Inc, Amarillo tvrtku koja prodaje zrakoplovne i vojne slušalice. O prije godinu dana, Brittain i Dalton pomogao pokrenuti drugu tvrtku, Dichonics Inc, s planovima kasnije za proizvodnju osobnih uređaja koji mogu isporučiti zvuk liječenje. “Mi ćemo nastaviti poboljšavati proizvod,” Brittain, rekao je. “No, sada, mi smo samo težak to sastaviti i staviti ga u ruke stručnjaka.” Iako tretman Dalton nastupa na ds ne daje dugoročne škripac za zujanje u ušima, On je rekao da misli da je davanje pacijentima svakodnevno pristup uređaju kod kuće će ih pustiti vlak njihov mozak u ignorirajući stanje. “Nakon što smo dobili na nano-tehnologije, možemo pretvoriti u vrstu slušni aparat,” , kazao je. Dok milijuni Amerikanaca pate od tinitusa, mnogo više ne izvješće uvjet, , rekao je Diana Wise-McPherson, Amarillo audiologist. Rekla je da je većina njezinih pacijenata pati od stanja. “Od posljednjih brojeva sam čuo, oko polovice svjetske populacije ima neku vrstu glave buke,” , rekla je ona. “Sada je li to smeta njihov život, to je druga stvar.” Tretmani za osloboditi tinnitus postoji, ali nitko od njih smanjiti ili ukloniti stanje, she said. Postojeći tretmani uključuju akupunktura i masaža terapije, rekla je onaid. “Ljudi učiniti sve vrste stvari, ali postoji ništa znanstveno dokazano na tržištu koji ublažava tinitus,” , rekla je ona. Ostali tretmani uključuju maskiranje šuma s drugih zvukova ili slanjem električne energije u uhu kohlea, Dalton je rekao. “No, pacijent još uvijek čuje nešto,” , kazao je. Mercer, rekao je razvila tinitus oko dvije godine nakon ugovaranja virus West Nile u 2004. Virus izazvao neki gubitak sluha, , rekla je ona. “U mom iskustvu, to može oslabiti,” , rekla je ona. “To mogu voziti vas lud. To je konstanta zuji u glavi. Ponekad, možete ga ignorirati, ali postoji vrijeme kada je samo glasno i to pogorša.” Izvor: Žuti
