I recently had what was described as a TIA with the CT showing white matter issues. It started with me feeling like I was falling and ending up unconscious on the floor with hands and feet feeling very cold. I could not speak (roughly five hours) but could write. I have inverted internal carotid arteries. The doctor I saw afterward, is disregarding what happened. In fact she said, "I have never seen anything like that, it isn't possible." Since that episode, I have experienced times when I stutter on words or unable to say certain letters. I do not know what to do. Has anyone experienced or have heard/know of such things?
