You are asking how to explain a stroke leading up to a stutter disorder. One thing that can maybe help you find the answer is to get diagnosed by a [neurologist](https://www.reddit.com/r/Stutter/comments/109rgos/comment/j400qhz/?utm_source=share&utm_medium=web2x&context=3), since he is specialized in diagnosing, treating and managing disorders of the brain and nervous system such as strokes, Alzheimer’s disease, migraine, multiple sclerosis, brain injury, Parkinson’s disease and epilepsy.
