Stroke is a clinical term that describes cell death in the brain. Stroke is a permanent and can result in significant functional impairment and even death. There are two types of strokes. The first is the most common and is referred to as ischemia. Nearly 80% of all strokes are ischemic and involves a blockage of blood flow that results in cell death. The other 20% of strokes are hemorrhagic that involves a bleeding outward from a weakened artery wall. As the blood gathers increased pressure can be placed on the surrounding brain tissue causing additional damage to the brain.

Both types of stroke are dangerous and can result in deficits of language, attention, information processing speed, and motor skills. Risk factors for stroke include advanced age, high blood pressure, diabetes, obesity, smoking, and poor diet. Typical preventative measures for stroke include the same protocol as used for the healthy heart. We have learned relatively recently how important blood flow to the brain is, particularly when we recognize that the brain commands 25% of the blood from every heart beat.

    First off I would like to say terrific blog! I had a quick question which I’d like to ask if you do not mind. I was curious to find out how you center yourself and clear your thoughts prior to writing. I have had a hard time clearing my mind in getting my ideas out there. I do take pleasure in writing however it just seems like the first 10 to 15 minutes are generally lost simply just trying to figure out how to begin. Any suggestions or tips? Appreciate it!

    When I originally left a comment I seem to have clicked
    the -Notify me when new comments are added- checkbox and now each time a comment is added
    I get 4 emails with the same comment. Is there a way you can remove
    me from that service? Kudos!
