Aerobic exercise training following stroke, as delivered through a cardiac rehabilitation program, increases blood flow throughout the brain, according to a study at Sunnybrook Health Sciences Centre. The small study, funded by the HSF Canadian Partnership for Stroke Recovery, compared seven people who took part in a six-month training program with 13 people who did not exercise. Brain imaging showed blood flow increased by as much as 20 percent in frontal regions of the brain, which are responsible for executive function. The goal is to design and deliver exercise programs to improve cognition after stroke.
