strokes are pretty wild when you really start to read into them. most people known of the slurred speech, one sided weakness symptoms but it depends on where the bleed or clot is in the brain and that'll change symptoms of the patient. like one guy i had was completely unable to see but could speak and move fine.

also, people who have had strokes in the past have a better chance of recovery from their next one because their brains develop what's called collaterals. they have develop extra vasculature to keep parts of their brain perfused with fresh blood and o2 for when they incase they have another one.
