As a medical professional with expertise in neurology, I can explain the causes of a brain infarction. A brain infarction, also known as a stroke, occurs when the blood supply to a part of the brain is interrupted or reduced, depriving brain tissue of oxygen and nutrients. This can lead to the death of brain cells in the affected area. The interruption of blood flow can be caused by several factors:
1. Thrombosis: The formation of a blood clot within a blood vessel that obstructs or blocks the flow of blood.
2. Embolism: A blood clot or other particle that travels through the bloodstream and becomes lodged in a blood vessel, obstructing the flow.
3. Atherosclerosis: The hardening and narrowing of arteries, which can lead to reduced blood flow to the brain.
4. Arterial dissection: A tear in the lining of an artery, which can cause blood flow to be disrupted.
5. Vasculitis: Inflammation of the blood vessels, which can damage the blood vessel walls and affect blood flow.
6. Cardioembolism: Clots that form in the heart, often due to conditions like atrial fibrillation, and then travel to the brain.
It's important to note that risk factors for brain infarctions include hypertension, diabetes, smoking, high cholesterol, obesity, and a family history of stroke.

A stroke occurs when the blood supply to your brain is interrupted or reduced. This deprives your brain of oxygen and nutrients, which can cause your brain cells to die. A stroke may be caused by a blocked artery (ischemic stroke) or the leaking or bursting of a blood vessel (hemorrhagic stroke).
