Strokes can cause brain damage and death. One way that stroke can cause brain injury is through a brain aneurysm , which occurs when the wall of a blood vessel weakens and creates a bulge.
This bulge can burst and cause a subarachnoid hemorrhage , which can lead to a stroke. Smoking causes atherosclerosis , which is when plaque builds up in the blood and sticks to the artery walls. This makes them narrower, reducing blood flow and increasing the risk of blood clots.
Smoking also damages the blood vessels, making them thicker and narrower. This makes it harder for blood to flow, and also increases blood pressure and heart rate.
