Possible causes of a cerebrovascular accident (CVA) include blockage in a vessel supplying the brain, a ruptured blood vessel, and damage leading to hemorrhage. Risk factors contributing to stroke are hypertension, atherosclerosis, heart disease, diabetes mellitus, cigarette smoking, and heredity.

Cerebrovascular accidents (CVAs), or strokes, can occur due to various factors that deprive brain tissue of oxygen. These include blockages in blood vessels, ruptured blood vessels, or other forms of damage that result in hemorrhage. Additionally, several risk factors increase the likelihood of a stroke, such as hypertension, atherosclerosis, heart disease, diabetes mellitus, cigarette smoking, and genetic predisposition.

Ruptured blood vessels may lead to hemorrhagic stroke.
Risk factors include hypertension and atherosclerosis.
Heart disease and diabetes mellitus are significant contributors.
