Brain Repair

According to the American Heart Association, stroke is the fourth leading cause of mortality in the United States and remains the leading cause of long term disability worldwide. Each year stroke-related costs total $71.6 billion and are projected to triple to $184.1 billion by 2030, with the majority of costs arising from patient care. Stroke is categorized as either hemorrhagic or ischemic, the latter accounting for 87% of strokes. Ischemic stroke results when an obstructed blood vessel cuts blood supply to the brain. Tissue in the surrounding region rapidly dies from deprivation of oxygen and nutrients, resulting in severe brain damage. The Segura Laboratory in collaboration with the Carmichael Laboratory at UCLA investigates the use of injectable hydrogels to promote brain repair after stroke.
