I disagree. Stuttering can not be treated. It can only be managed and reduced. It's this denialism that is causing people suffering that they think that some new idea or method will spark a full blown recovery. My own personal theory is that stuttering is caused by some deficiency in the speech appartus and exasperated by states of mind and being. It will not ever be sufficient enough for reliable fluency. It's not something you treat like a virus in your body. Only a future biotechnology I think can solve the issue, but the fluency will be dependent on that technology. You have to accept it but not let it stop you. It is a part of who we are to deny it would stunt personal development.
