Objectives: After studying the article, you should be able to:

• Define a migraine.

• Describe Wolff’s vascular theory to explain the cause of migraine headaches.

• Explain extracranial vessel diameter and Peak Systolic Velocities for people who suffer from migraines during active headaches and non-active headaches.
