Stroke

A stroke is the sudden death of brain cells due to lack of oxygen. A stroke is usually defined as one of two types:

• Ischemic (caused by a blockage in an artery)

• Hemorrhagic (caused by a tear in the artery's wall that produces bleeding into or around the brain) The consequences of a stroke, the type of functions affected, and the severity, depend on where in the brain it has occurred and the extent of the damage.
