Probably not, at least for persistent developmental stuttering. Stuttering is not caused by any kind of hormone or chemical imbalance as far as we know. If it were then medication could theoretically be developed but I don't see that happening. The most promising option I've come across is something called the Valsalva Hypothesis. It was developed by Dr. William Perry, a chronic stutterer that was originally a lawyer and then became a speech pathologist. I found his book quite enlightening. http://www.valsalva.org/ Video presentation: Part 1 of 2: https://www.youtube.com/watch?v=lh2fbLL1rOk Part 2 of 2: https://www.youtube.com/watch?v=vkiAIXeXN-o I'm trying to work on this. The biggest challenge is finding time to practice every day, but it does seem to help.
