Hearing has a natural tendency to come back to a certain extent on its own, I wonder if this comes into play? After a recent acoustic trauma, I went from hardly being able to hear, to a gradual improvement over a few months doing nothing at all. If I were taking a drug, would that drug be given credit for my limited recovery?
My hearing is still very damaged, but there has been some improvement. I've heard of this same experience from many people. How do they know the drug was the factor in the mice, and not just a normal somewhat limited improvement? I would be especially cautious if the improvements were marginal, and the treatment began immediately after the induced hearing loss.
Don't beat me up here. Haha. I don't know a lot about these studies, maybe I'm way off base.
