Natural Protein Could Reduce Brain Damage Caused by Stroke

California scientists have found that a protein, which occurs naturally in the body, might reduce brain damage caused by a stroke.

Stroke is the world’s second leading killer, responsible for almost 10 percent of all deaths worldwide in 2005, according to the World Health Organization. Eighty five percent of those deaths occur in low and middle income countries and one-third strike people under 70.

Stroke is also the leading cause of serious disability among adults.

A stroke occurs when the blood supply to the brain is interrupted, usually due to a burst blood vessel or a clot. When that happens, the supply of oxygen and nutrients is cut off, causing damage to the brain tissue.

Time is critical for stroke victims. The longer blood flow is cut off to the brain, the greater the damage. The U.S. National Institute of Neurological Disorders and Stroke says immediate treatment can save lives and enhance chances for a successful recovery.
