Stammering is a secondary manifestation of local brain damage. Simply put, all normally speaking people speak without any problems, without thinking how to do it, for in a healthy person speech provides an unconditioned (innate) reflex. In people with stuttering, this reflex is broken (i.e. the connections in the brain responsible for speech are broken) and the brain compensated it with a conditioned reflex (habit) of stuttering speech. I am stuttering too from Russia. I am use meldonium dihydrate , which improves brain blood circulation https://en.wikipedia.org/wiki/Meldonium.
