C. Striving for Better Therapeutic Interventions for Stroke Patients
trong>Narrator: This is Science Today. Stroke remains the leading cause of adult disability in this country due to the amount of brain tissue that's often damaged during an attack. That's why researchers are working on providing early treatment for stroke patients to lessen the amount of tissue damage in the hopes that the brain's own repair mechanisms will be more effective and lead to a greater recovery. Dr. Steve Cramer, co-director of the clinical stroke program at the University of California, Irvine, says most stroke patients do get somewhat better after a stroke.

Cramer: That is to say, the natural history of stroke, is that there is some behavior of recovery, it's just not enough. So, while we work on getting people into the hospital in those first precious few hours with one hand and we work on getting the clot busters to patients with that one hand, getting them in those first few hours, at the same time, we can target these repair processes, which have a much wider window for therapeutic intervention.
