There is current research into medication-mediated stuttering. There is currently an NIH study: https://pubmed.ncbi.nlm.nih.gov/32292321/#:~:text=Abstract, the%20severity%20of%20stuttering%20symptoms also https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7118465/ The physician who researched this is: Dr. Gerald Maguire. He has Youtube videos and you can Google him too. This might not be the answer for every stutterer, but it is a first step toward treating a neurological condition. Stuttering is also emotional, but having a leg-up on the physiological aspect is a good start. Sue
