Stroke, the fifth-leading cause of death in Florida according to the American Heart Association, is expected to continue to rise among baby boomers. In Florida, the number of stroke-related deaths has been declining but remains 28 percent of stroke victims. Ten years ago, that number was 47 percent, according to the Center for Disease Control. Vigilance remains important, said Lesia Mooney, stroke coordinator at the Mayo Clinic in Jacksonville. She expects the number of strokes to increase again because of the large number of aging baby boomers.
