Hello, as a stutterer, suffering from it, to exchange my relatively one-sided view of stuttering, I think stuttering has a genetic relationship, Genes cause different physical structures in the brain, because I have a familial stammer, from my grandfather's generation to my generation, Every generation finds people who stutter. I think stuttering is a condition of uncontrolled conditioning in certain situations, and fear of heights, There's a similar mechanism, and it might help you with your stuttering research. There's a phobia that's interesting, like sickness, There are different types of dizzy blood, not what blood dizzy, some dizzy their own, some dizzy other people's blood (although the same blood), Do others think they are cowardly and afraid of blood? Many patients describe fear as similar to normal people. Studies now make it clear that when they faint, the vagus nerve is abnormal, causing vasoconstriction, cerebral ischemia, Fainted, so it can be said that dizzy blood is a direct psychological cause (because only see a specific type of blood will faint), But the essence or halo blood disease individual brings different from ordinary people related physiological reaction mechanism, the patient is not afraid of blood, is to see blood uncontrolled fainting, Next time there will be fear, reinforced by the above case is not a bit like stuttering (stutterers do not stutter in all situations), Most people who stutter are also normal people's mental endurance is due to long-term uncontrolled speaking to people lead to psychological disorders, All the obvious negative, now many people misunderstand that it is because of anxiety and fear caused by stuttering, but it is not, Because long-term speech stuttering causes psychological disorders, because stuttering is so deceptive, Many people prefer to believe that psychological problems lead to stuttering. The first is that the left and right brain languages interfere with each other. This is normal. In the second case, the article reports a shift in blood flow in the area of the brain that controls language. There's a sudden drop in blood flow between speech and brain areas, no energy supply, Abnormal language areas are logical. Is the second scenario a bit like halo? Both are dysfunctional due to ischemia in the brain, but in patients with hematosis, it's the contraction of the main blood vessels that causes ischemia in the entire brain, Affecting motor function, etc., leading to fainting and stuttering in patients with abnormal language areas leading to stuttering, Other brain regions are normal when stuttering occurs, so hearing, sight, touch, etc., are normal, When stuttering occurs, there is a similarity between hematochezia and stuttering, which is helpful to clarify the direction of research. So we're going to focus on stuttering, what happens to the state of the language area, what happens to the language area, Will not be because of the language area next to the uncontrolled contraction of blood vessels, leading to abnormal blood supply, causing abnormal language expression, Leading to the possibility of stuttering and so on this is only a simple personal view, if not correct, Because I am not a professional engaged in this research do not know what I said do not understand [ happy ] the above is translated from Chinese into English may be some words exist ambiguity, hope to understand
