New research funded by charity Action on Hearing Loss suggests that tinnitus can be eliminated by blocking signals between the ear and brain, offering hope to suffers that a cure is within reach, with prolonged exposure to loud music or working in a noisy environment often the main reasons why people are affected by the distressing condition.
Researchers at the University of Western Australia treated guinea pigs with a drug called furosemide one week after tinnitus had been triggered by exposure to loud noise. The drug treatment lowered the activity of the auditory nerve, reduced neural hyperactivity in a specific part of the brain that processes sound and crucially the animals treated with the drug no longer displayed signs of tinnitus.
Dr Helmy Mulders who led the research said: 'Studies in human tinnitus sufferers are still needed to confirm our results and to establish whether or not this approach will be effective for people who have had tinnitus for a long time, but our research shows that lowering the activity of the auditory nerve may be a promising approach to treating recently triggered tinnitus.'
