Cerebral Stroke

A stroke occurs when part of the brain loses its blood supply and stops working. This causes the part of the body that the injured brain controls to stop working. A stroke also is called a cerebrovascular accident, CVA, or “brain attack.” The types of strokes include: Ischemic stroke (part of the brain loses blood flow) Hemorrhagic stroke (bleeding occurs within the brain) Transient ischemic attack, TIA, or mini-stroke (The stroke symptoms resolve within minutes, but may take up to 24 hours on their own without treatment.

What causes a stroke?

The cause of a stroke depends on the type of stroke. The three main types of stroke are transient ischemic attack (TIA), ischemic stroke, and hemorrhagic stroke. A TIA is caused by a temporary blockage in an artery that leads to the brain. The blockage, typically a blood clot, stops blood from flowing to certain parts of the brain. A TIA typically lasts for a few minutes up to a few hours, and then the blockage moves and blood flow is restored.
