A stroke is something that can happen to a person’s brain. It can make them feel really sick and have trouble moving. Just like our body needs lots of blood to stay healthy, our brain needs blood too. Sometimes, a part of the brain doesn’t get enough blood because something blocks it. It’s kind of like a traffic jam inside the brain. This can make people have a hard time speaking, walking, or even seeing. It’s important to call for help right away if someone is having a stroke so that doctors can try to fix it and make the person feel better.
