I believe in neurological science / research. The causes of stuttering will probably not be curable for a long time, but the symptoms will be. It will take time to treat them. The treatment, however, will not be to simply drop the "N" from the word "NASA", smile when speaking, or paraphrase any words. However, since I am not a neuroscientist, I cannot contribute to this. I can only provide my body for clinical studies.
