Delaware Attorney General (and son of VP Joe Biden) Beau Biden, 41, checked himself into a hospital yesterday morning with a headache. The cause was mild stroke, doctors say, and he is expected to recover fully.
Vice president Biden is known to have had an aneurysm in 1988 at the age of 45. It's not clear if family history played a role in Beau's stroke.
Each year 700,000 people suffer a stroke. Five hundred thousand of these strokes are first occurrences, while the rest are repeat strokes. According to ABC News, approximately 10 to 15 percent of strokes occur in people under 45.
