I've read the research. I can say with confidence that there isn't an inherent problem with us psychologically. There are certain mechanisms in the brain that are associated with stuttering, just like there's a mechanism for parkinsons disease or epilepsy. A mechanism that comes up time and again in the literature is hyperdopamine in the brain, or conversely, hypodopamine. There's more involved but dopamine dysregulation is a common theme. I personally believe that the mechanisms have been researched and laid out. What needs to happen is to translate that research into treatments that manage the neurological disorder, just like any other neurological disorder is managed. DM me to learn more.
