About Ischemic Stroke

Ischemic stroke,the most common type of stroke,occurs as a result of an obstruction within a blood vessel supplying blood to the brain. Approximately 15 million people worldwide suffer stroke each year,of which approximately 87% are ischemic strokes. Post-stroke motor deficits include paralysis in arms and legs and can be permanent. No interventional therapy exists for chronic stroke and treatment is focused on rehabilitation,but only a small fraction of survivors achieves complete functional recovery.
