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.

∙ 13y agoA stroke occurs when blood flow to the brain is disturbed. This can be lack of blood flow (ischemia) caused by blockage (thrombosis/arterial embolism), or blood leakage (hemorrhage). Some medical symptoms are as follows:
- Loss of motor control to one or more limbs on one side of the body.
- Loss of intelligable speech, i.e. slurred words or inability to speak.
- Sudden weakness of the face.
- Altered smell, taste, hearing or vision.
- Decreased sensation and/or reflexes.
- Problems with balance.

∙ 9y agoWhen a person suffers a stroke, it means something has stopped normal blood flow to the brain. This can occur if a weakened blood vessel ruptures and bleeds into the brain. A stroke can also occur if a person develops a blood clot that blocks the flow of blood to the brain. Strokes are extremely dangerous, and can be fatal. If you suspect you are having a stroke, call 911 immediately.
