In brief: Blood flow changes?
The actual cause of migraine headaches is not known.
The vascular theory says that changes in the size of blood vessels leading to the brain causes changes in blood flow, with increased flow causing pain. The neurovascular theory says changes in brain signals and brain activity cause blood vessels to change sizes, resulting in pain from increases in blood flow. Additional theories also exist.

More recent evidents points to neurologic cause rather than vascular.
