My speech therapist specializes in traumatic brain injury. When I first started the therapy, she said that I should expect to have more problems when I am stressed, tired, or under cognitive strain. Being relaxed, explaining something that I have said repeatedly (like how the injury happened) made my speech almost like it was before the accident.

I was really amazed at how much the speech therapy really helped. The breathing techniques and learning transitions from one syllable to another and easy onset of words made a huge difference. After a while I was able to self-correct. Now, unless I am exhausted or have not planned what I want to say, no one suspects that I ever had a stutter.

I wouldn't be concerned if the neurologist is not familiar with this, but your speech therapist says something different, I would look for a new speech therapist -- one with experience treating patients with TBI.
