Hi, I have had a stutter since I was a child. I have tried multiple treatments and for awhile got into TDCS (Transcranial Direct Current Stimulation). The treatment I have learned that works the best is to learn how to treat the underlying condition and become okay with having a stutter first. I know it sounds cliche but it has helped me a lot. Another treatment that works is anti-psychotics although they are not for everyone and can have some really bad side effects. TDCS did nothing for me personally. Hope this help! If you have any questions feel free to comment or write me!
