More Info on The possible Causes of Stuttering

I have been doing more research and found some new noteworthy info on the subject.

It appears that some experts think it is brain damage after all; For many years, scientists believed that stuttering was a behavior that kids learned early in life, and that it was not a genetic trait, or something caused by some other biological factors. But according to Dr. Barry Kosofsky, chief of pediatric neurology at New York Presbyterian Hospital, "more studies are demonstrating the role genetics and the brain play in stuttering."
One theory says that the brains of stutterers might contain too much dopamine, a brain chemical that also plays a part in Parkinson's disease, drug addiction and mood disorders. (Dopamine is a monoamine neurotransmitter found in the brain and essential for the normal functioning of the central nervous system.)
Pagoclone, the possible drug for stuttering that I mentioned in my previous posts might work by lowering dopamine levels in the brain.
Some more research from the Universities of Hamburg and Gottingen report chronic stuttering seems to be the result of a lapse in the brain's cortex in the left hemisphere, the area responsible for speech.
Cornelius Weiller, director of the University of Hamburg's neurology institute states that there is possibility that this structural change occurs during childhood when early language and speech-acquisition skills are being developed. However, it is unsure why some children who stutter go on to become fluent speakers and others must endure longer lasting and may be a lifetime of stuttering.

But there is some good news: Since the left part of a stutterer’s brain is not so good, many say the right part of the brain becomes better. The right Hemisphere controls Spatial abilities, face recognition, visual imagery, and Music, while the left controls language, math and logic.

And remember that stutterers are generally smarter than “normal” people!
