What happens when a person has a stroke?
A stroke is any disruption to blood flow around the brain. Technically, the blood/brain barrier does not allow blood to actually enter the brain. That can be one example of a stroke, if a blood vessel ruptures and causes blood to enter the brain. In normal operation, nutrients cross the blood/brain barrier to provide for the needs of the brain. If a blood clot stops blood circulation in an area of the brain, it's also considered a stroke. Typical body function during a bleeding event is to first stop the bleeding and then initiate repairs. All of that takes place without much thought on our part. The platelets form a shield around the cut other damaged area and stop the bleeding. When this happens inside the brain, part of the brain dies. When a blood clot forms inside the brain, nutrients are stopped and that too can destroy brain cells.
