USA HISTORY

Detailed explanation-1: -A stroke causes brain tissue to die, which can lead to brain damage, disability, and death. Stroke is the fifth leading cause of death in the United States and the leading cause of serious long-term disability. This is disturbing because about 80% of strokes are preventable.

Detailed explanation-2: -A stroke, sometimes called a brain attack, occurs when something blocks blood supply to part of the brain or when a blood vessel in the brain bursts. In either case, parts of the brain become damaged or die. A stroke can cause lasting brain damage, long-term disability, or even death.

Detailed explanation-3: -There are two main causes of stroke: a blocked artery (ischemic stroke) or leaking or bursting of a blood vessel (hemorrhagic stroke). Some people may have only a temporary disruption of blood flow to the brain, known as a transient ischemic attack (TIA), that doesn’t cause lasting symptoms.
