Step-by-step explanation:
A stroke, also known as a cerebrovascular accident (CVA), occurs when blocked or broken arteries in the brain result in the death of brain cells. There are two main types of stroke: ischemic stroke and hemorrhagic stroke. Ischemic stroke occurs when an embolus, such as a blood clot, becomes lodged in an artery in the brain, blocking blood flow. Hemorrhagic stroke occurs when a weak blood vessel ruptures and bleeds into the brain.
