Medical researchers have known for several years that there is some sort of link between long-term depression and an increased risk of stroke. But now scientists are finding that even after such depression eases, the risk of stroke can remain high.

Scientists don't yet know the mechanisms involved, she says — why depression would predispose someone to stroke. It could have something to do with the body's physical reaction to the psychological malady, Glymour says.

"Changes in immune function," she says, "[or] inflammatory response, nervous system functioning — all of these might influence blood pressure [or] cortisol levels and thereby increase your risk of stroke."

"There is no health without mental health," Binder says, adding that people should be routinely screened for depression and anxiety when they see their primary care provider.

The good news, Binder says, is that depression can be "extremely treatable" once it's addressed. A short course of psychotherapy or a short course of medication, she says, can quickly turn things around in many cases. - Read More at NPR
