Strokes are brain attacks. They occur when the blood supply to the brain becomes blocked. A stroke is a medical emergency that needs immediate medical attention.During a stroke, the brain does not receive enough oxygen or nutrients, causing brain cells to die.Strokes need to be diagnosed and treated as quickly as possible to minimize brain damage.
- Ischemic stroke: This is the most common type of stroke. A blood clot prevents blood and oxygen from reaching the brain.
- Hemorrhagic stroke: Hemorrhagic strokes are caused by blood leaking into the brain
- Transient ischemic attacks (TIAs): Also referred to as a mini stroke, these occur after blood flow fails to reach part of the brain. Normal blood flow resumes after a short amount of time, and symptoms cease
