    Stroke is the sudden loss of neurological function caused 
         by an interruption of the blood flow to the brain.
    Ischemic Stroke: A clot          Hemorrhagic Stroke: Blood 
      blocks or impairs blood            vessels rupture and leak in 
      flow.                              or around the brain.
       Motor deficits are characterized by paralysis 
      (hemiplegia) or weakness (hemiparesis) typically 
      on the side of the body opposite the side of the 
                     lesion.

  4th Leading cause of death in the United States
  1st Cause of long-term severe disability
  700,000 strokes a year
  5,400,000 estimated stroke survivors= 2.6% of population
  18.8 billion costs for care in the United States
  Incidence is 1.25 times greater for males than females
  Highest Risk for African-Americans, American Indians and Alaska 
    Natives.
  Lowest  Risk for Asians and Native Hawaiian/Other Pacific 
    Islander
