Anticoagulant (blood thinning) medications make bleeding into the brain more likely, especially if taken improperly or in large doses.
Cerebral (brain) aneurysms (enlargements of blood vessels)
Substance abuse
Family history of strokes
Smoking, diabetes, high cholesterol, obesity, and a sedentary lifestyle are risk factors for all types of strokes.
