I know a few people who do one has gone to speach therapy and its almost completly gone the other who is older, still st studders when hes nervous, or lieing talking about things he has no idea about what hes talking about.
I personaly think that unless you have tourets(sp?) that its something that can be changed through cognative behavior modification or brought to a lesser degree.
Did you ever see Pans Labrinth(where the guy studders) but if he can count to three or five with out studdering he can go free. Dosent make it and gets messed up by the dictator who gets messed up by the studdering guys girlfriend.Pretty crazy show none the less.
