Understanding How Brain Aneurysms Form May Help Predict Ruptures
Once blood vessels lose the ability to expand and contract with each heartbeat, artery walls are more prone to rupture.
A new study from UC San Francisco shows how certain cells in the brain may cause aneurysms to weaken and rupture. It helps explain why some aneurysms burst while others do not and could lead to new ways of predicting and possibly preventing strokes.
