What causes stroke?
Ischemic stroke is typically caused by fatty deposits that accumulate inside of blood vessels, causing them to become narrow or blocked and severely restricting the flow of blood. These blockages can also occur due to blood clots or other debris that become lodged in the blood vessels of the brain. Hemorrhagic stroke can occur due to factors such as abnormally high blood pressure, brain aneurysms, physical trauma, excessive blood thinner treatment, or a buildup of protein deposits in the inner walls of the blood vessels.
Lifestyle factors such as obesity, physical inactivity, heavy drinking, smoking, and the usage of certain drugs can increase your risk of experiencing a stroke. Additionally, medical conditions such as diabetes, high cholesterol, sleep apnea, and heart disease, as well as a personal or family history of stroke, may also increase your risk. Stroke is also most common in men, people over the age of 55, people who are Black or Hispanic, and people who take hormone-affecting medication that increases estrogen.
