Difference between Headache and Stroke

Headache vs. Stroke

Headache is the symptom of pain anywhere in the region of the head or neck. A stroke is a medical condition in which poor blood flow to the brain results in cell death.

Aneurysm

An aneurysm is a localized, abnormal, weak spot on a blood vessel wall that causes an outward bulging, likened to a bubble or balloon.

Cerebral arteriovenous malformation

A cerebral arteriovenous malformation (cerebral AVM, CAVM, cAVM) is an abnormal connection between the arteries and veins in the brain—specifically, an arteriovenous malformation in the cerebrum.
