What's a stroke?

Every 40 seconds an American suffers a stroke.  One in every 18 deaths in the United States is caused by a stroke.  In 2008, 60.1% of all stroke deaths involved women.  American Heart Association, Women and Cardiovascular Disease, http://www.heart.org/idc/groups/heart-public/@wcm/@sop/@smd/documents/downloadable/ucm_319576.pdf

What’s a stroke?  It’s damage that occurs in the brain when oxygen delivery to an area of the brain is interrupted.  A stroke can be caused by two different occurrences:  from ischemia (lack of blood supply) and a hemorrhage (bleeding within the brain).  Approximately 85% of strokes are ischemic strokes.  In this type of stroke, plaque buildup inside the arteries and/or a blood clot interferes with the blood flow to the brain.  During a hemorrhagic stroke, a blood vessel to the brain ruptures and blood accumulates into and around the brain tissue.   http://circ.ahajournals.org/content/123/4/e18.full  

Time is critical in the treatment of stroke.  According to the National Stroke Association, the first three hours after onset of stroke symptoms are the recommended timeframe for ‘clot-busting drugs.’  http://www.stroke.org/site/PageServer?pagename=treatment   

How can you know if your loved one is dealing with stroke symptoms?  Take the FAST test.  More tomorrow.
