I don't think there will be a cure in 20 years. My reasons are not scientific. So many people spontaneously habituate to mild tinnitus that big Pharma doesn't want to invest. Sorry to be so cynical. I had a best friend who died from a rare disease--scleroderma--not enough people died so it wasn't a money maker--so no drugs were developed. Only a small percentage has debilitating tinnitus. Those of us in between as well as those debilitated don't matter. That's the facts of life in our profited minded society.
Also, scientists really don't understand the difference between mild, moderate and severe tinnitus and even though they deny it, they think it's all a matter of 'perception' --meaning it's really 'not so bad, so there, there, it will be okay if you learn to live with it.'
Snake oil salespeople, lipoflavanoids, supplements, etc. are making a fortune. Need I go on?
