This sounds like a good question for one of our national stroke associations to answer.
NSA 1 - 800 - 787 - 6537
ASA 1-888-478-7653
Of course it is possible to not have a second or subsequent stroke. It all depends on what caused your first and what you have done to adress the causative issues & any other stroke risk factors.
My GP places this (secondary prevention) the highest on his priority list - above rehab even, which he leaves to my & my therapists.
I have seen young people who have had multiple strokes & I do NOT want to bee one of them.
