Have you learned that someone you care about had a stroke? Don't jump to conclusions about how it will affect him. Not all strokes are created equal. There are three major kinds, with different warning signs and symptoms.
All types have one thing in common: a loss of blood to part of your brain. That causes big problems.
Your brain cells need the oxygen that's carried by your blood. So when a stroke cuts the supply, some of the cells start to die. And that sets off trouble like memory loss, confusion, and numbness on one side your body.
