10 Causes of Stuttering
Cause #3: Neurophysiology
The brain is, by far, the most complex structure that we know of in the universe. We have only just scratched the surface of understanding how it works and even our most advanced computers cannot come close in terms of computing power. As is usual for things that are complex, though, there is a lot that can go wrong.
If there is something not quite right in the brain and/or other parts of the central nervous system then our speech can suffer. This can lead to a stutter, but getting to the exact cause can be all but impossible. There is a great deal more research to be done before we get close to having answers.
