Stroke risk rises in people who are depressed
People who are depressed are more likely to develop heart disease than those who aren't. It works the other way, too — people who have heart disease are more likely to lapse into depression than their disease-free counterparts.
The same association appears to exist between depression and stroke. This isn't a huge surprise, considering that the conditions that cause heart disease — like clogged arteries and inflammation — also contribute to strokes. Still, researchers can only speculate on how depression contributes to these dangerous cardiovascular events or the biological disorders leading up to them.
