A new study shows people who are depressed may be a little more likely than others to suffer a stroke down the road.Looking back at 28 past studies, researchers estimated there would be 106 extra cases of stroke per 100,000 depressed people each year, 22 of them fatal. But don’t reach for the antidepressants just yet, because the study has major limitations. The biggest problem is that nobody knows how to account for the link -- people who have the blues might smoke more and exercise less, for instance. Indeed, accounting for that did weaken the apparent tie between depression and stroke, which kills about 137,000 Americans a year.
