Final answer:
Headaches may or may not be a symptom of a CVA. Hemorrhagic strokes can cause severe headaches, but in other types of stroke, headaches may not be a common symptom.
Step-by-step explanation:
A hemorrhagic stroke can cause a severe headache. In other types of stroke, headaches may not be a common symptom. A migraine, which is a more severe type of headache, occurs when blood vessels in the head dilate or expand. Headaches may also be a symptom of serious diseases, but they are more commonly due to muscle tension.
