2. Explaining an Ischemic Stroke
Unfortunately, most strokes fall into this more serious category, which can be broken down into 2-subtypes (thrombotic and embolic), explains WebMD. An ischemic stroke is caused by a fatty buildup (also called plaque) that builds up in your arteries and narrows them, subsequently impeding the flow of blood, it adds.
Thrombotic versions of a stroke are the result of a blood clot in an artery that feeds the brain, while an embolic version is a clot that forms elsewhere in your body and then travels to your brain, adds the source. These types of strokes will cause brain damage, but the extend will differ by case.
