I mean , looking at the people who have acquired stammer , which could be caused by brain injury or stroke etc . The only difference i find when listening to them is that their disfluencies are easy and no coping mechanisms ( word avoidance and substitution , tensing up or any hesitations ) are there. They just stutter and they dont substitute words unlike the people with PDS (persistent developmental stutter ) from childhood. Most people with PSD show obvious tension while speaking which is clearly distinct from Neurogenic Stammer. Also , i think neurogenic stutterers are much more comfortable while speaking even though they might be severely disfluent. Thats the goal i want to achieve , to stutter but do it without tension or secondaries Im also emphasizing that not all our stuttering incidents would have been caused by preliminary neurological defect in speech areas of the brain but would rather have been caused by our association between certain words or sounds. Our anticipation of stutter is what makes us more likely to stutter. Not to mention , im NOT saying that anticipation causes the our stutter in the first place, it just increases the probability of us stammering. Some people here think that im blaming everything on stutterers which ofcourse is far away from being true. Its ABSOLUTELY NOT OUR FAULT! Thats the reason most people have troubles with their names. (Luckily i dont cuz my name doesnt start with consonants which are hell for me to say ) . They sometimes even change it to easier one but unluckily find themselves stuttering on that too.
