A stroke can result if a blood vessel in the brain becomes blocked, either by a clot or other type of embolism. When this occurs, blood flow to the affected area of the brain is stopped, and that area of the brain loses function, sometimes permanently.
A myocardial infarction (heart attack) also occurs as a result of a blocked vessel, however this occurs in the heart, not the brain.
An aneurysm is the enlargement and weakening of a blood vessel, and is susceptible to rupture. While this can occur in the brain, causing a hemorrhagic stroke, it is not due to a blockage in the blood vessel.
Migraines are painful headaches that can last for several hours to days. The causes of migraines are not fully understood, but there are several environmental and physiological factors that may contribute to their onset. While migraines can be severely painful, they are not associated with blocked blood vessels in the brain.
