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 tOllamh's bhFáinní Taighde Tinnitus Fíor Márta 29, 2011 ag Emma Comhdaithe faoi Réadmhaoin, Tinnitus Nuacht Is ollamh ag West Texas A&Féadfaidh M Ollscoil ag teacht ar bhealach chun cabhrú le laghdú nó a bhaint tinnitus buan, ar choinníoll go bhfuil cúiseanna ar tairiseach, agus is minic irritating, glaoch ar an chluasa. An Tinnitus American Association tuarascálacha a chuireann isteach ar tinnitus suas go dtí 50 milliún Meiriceánaigh. Bíonn na cúiseanna atá leis an riocht ach tá cailliúint éisteachta, nochtadh do torann ard, tinneas tromchúiseach agus ar thomhaltas na substaintí sin mar Nicitín, Caiféin agus leigheas. Leslie Dalton, ina ollamh in óráid WT agus clinic éisteachta, Chaith an am atá thart 12 bliana a fhorbairt chóireáil tinnitus sheachadadh trí úsáid a bhaint den chuid is mó ar shlis, bogearraí agus cluasáin móra. Cuireann an sliseanna fuaim chiúin agus réamh-cláraithe leis na cluasáin, Bíonn athrú na fuaime bealaí chun teacht ar an inchinn. Dalton, sa tríú bliain ag LT, likens leis an bpróiseas chun bóithre a atheagrú a athrú ar an mbealach a shroicheann feithicil a cheann scríbe. Cibé mar thoradh ar na coinníollacha a tinnitus difear d'fheidhmeanna an inchinn gnáth, is cúis leis an fhuaim glaoch, dúirt sé. “Cúiseanna sé an inchinn a athphróiseáil san áit mhícheart,” dúirt sé. “Táimid ar ais ar an éisteacht ionas go ndéanfaidh an ghnáthchuid den inchinn os a chionn.” Dalton Tá feicthe roinnt rath lena chuid oibre. Gretchen Mercer, a ghlac cóireáil Dalton's cúpla uair le linn na bliana seo caite, Dúirt an modh a bhaint go hiomlán í tinnitus aon uair a chuir sí ar na cluasáin. “An chéad uair a chuir mé ar na cluasáin, mo chorp ar fad ach réchúiseach,” Dúirt sí. “éisteacht leat aon rud. erases sé go hiomlán ar an tinnitus.” Ceann de na cuspóirí leis an taighde tinnitus é a chruthú fhréamhshamhail féidir a dháileadh ar chlinicí éisteolaíochta áitiúil roimh dheireadh an tsamhraidh, Dúirt Paige Brittain, úinéir Headsets Inc, gnó Amarillo go sells headsets eitlíochta agus míleata. Faoi bliain ó shin, Brittain agus chabhraigh Dalton tús a chur suas cuideachta eile, Dichonics Inc, le pleananna a mhonarú feistí déanaí pearsanta is féidir a sheachadadh an chóireáil fuaime. “Leanfaimid ar aghaidh le feabhas a chur ar an táirge,” Dúirt Brittain. “Ach anois, táimid ag iarraidh ach chun é a chur le chéile agus é a chur i lámha na speisialtóirí.” Cé go soláthraíonn an chóireáil Dalton fheidhmíonn ag LT aon shocrú fadtéarmach do tinnitus, dúirt sé cheapann sé go mbeadh rochtain a thabhairt d'othair go laethúil le gléas sa bhaile in iúl dóibh a n-oiliúint brains isteach neamhaird ar an riocht. “Nuair a fhaigheann muid a nana-teicneolaíocht, is féidir linn dul isteach ar chineál an chúnaimh éisteachta,” dúirt sé. Cé go bhfuil na milliúin Meiriceánaigh ag fulaingt ó tinnitus, bhfad níos mó ná tuairisc ar an gcoinníoll, Dúirt Diana Wise-McPherson, éisteolaí Amarillo. Dúirt sí an chuid is mó de na h-othar ag fulaingt as an riocht. “Ón líon roimhe seo chuala mé, thart ar leath de dhaonra an domhain tá ceann de shaghas éigin torainn,” Dúirt sí. “Anois, an bhfuil bothers sé ar a saol, é sin rud eile.” Cóireálacha tinnitus faoiseamh a bheith ann, ach aon cheann acu a laghdú nó coinníoll a bhaint, she said. measc na cóireálacha atá ann cheana agus massage acupunctuDúirt sípe, she said. “Daoine a dhéanamh ar gach cineál rudaí, ach níl aon rud go heolaíoch cruthaithe ar an margadh go alleviates tinnitus,” Dúirt sí. cóireálacha eile tá masking an tinnitus le fuaimeanna eile nó leictreachas a sheoladh isteach an chluas's cochlea, Dúirt Dalton. “Ach cloiseann an t-othar fós ag rud éigin,” dúirt sé. Mercer dúirt fhorbair sí tinnitus thart ar dhá bhliain tar éis conarthach na Níle Thiar víreas i 2004. Tá an víreas is cúis éigin cailliúint éisteachta, Dúirt sí. “I mo thaithí, Is féidir é a debilitating,” Dúirt sí. “Is féidir leat tiomáint mbarra. It's a humming leanúnach i do cheann. Uaireanta, is féidir leat neamhaird a dhéanamh air, ach tá amanna nuair atá sé díreach os ard agus a olcas atá an scéal.” Foinse: Buí
