I think one day there will be a cure when they can figure out the receptors in the brain that is having a hard time figuring out what to do with the misinformation of sound. It's similar to a station that doesn't come in clearly but you keep adjusting and soon the signal is clear and you can make sense of the words on the radio. The part of the brain responsible for processing the sounds is getting interference and it doesn't know what to do with the noise. It doesn't know how to process it. It's really complex and since so many people suffer from it, it's only a matter of time before they get it figured out.
