I don't know anything about stuttering as a result from trauma. But with the more common form of stuttering starting in childhood there seems to be a strong genetic component. Some researchers now think it may stem from a little to much dopomine and or not quite enough gaba ?

Any way it's been found that about 30% of people who stutter get a lot of help from taking 100mg of vitamin B1 3 times a day. It works best when taken by itself not as a multivitamin. But sometimes taking some magnesium is necessary for it to work. And the substance tannin in coffee and tea interfere with absorbing B1. When this works it works fast the effect is noticeable in a few days and if no improvement is noticed in 2 weeks it just isn't going to work for you. Note I said 100mg 3 times a day taking it all at once just isn't as good. What this may do is raise your gaba levels a little bit.

Now something I found that makes me stutter more is using fish oil supplements. It seems that omega3 fatty acids may raise your dopomine just a little bit. Well as I said this is just for the common form of stuttering and it only helps about 30% of those that try it. But heck a $4 bottle of B1 last me month. For more info just google stutering and thiamine .

Ditto . . . fatigue, poor sleep, sensory overload and stress all contribute to stuttering. Even get inventive with my speech for no apparent reason too.

Cafe had 'dropped scones' on the menu and much to my friends amazement she heard me ask for a 'drone'
"What the hell is a drone?" she asked of me.
I did not need to answer, the girl behind the counter spoke for me
"We all know her here, it's a dropped scone she wants."

I was impressed as had not ordered this before. . . but as a regular before my accident . . . now anything had become acceptable.

I speak of the colour 'gream' (a cross between green and cream) commonly seen in flowers, ' messle and portar' confusing a few folk - The list goes on. Love it how my inventive language has caught on with some friends who now regularly use the colour 'gream' to describe flowers.

With language and stuttering I couldn't help noticing how it's the letters we first struggled with when learning to talk, b,p,f,w,t that caused the problems and still do when fatigued, overstimulated etc.
