Strokes are increasingly killing younger people, especially in developing countries where unhealthy lifestyle habits have taken hold, according to a study funded by the Bill & Melinda Gates Foundation.
While strokes are usually thought to afflict older people, the number of people ages 20 to 64 who experience them has risen by 25 percent in the past two decades, according to researchers from countries including the U.S., U.K. and Japan. This younger group now makes up 31 percent of total strokes, compared with 25 percent before 1990, the study found.
