  • Look Inside

The exact pathophysiological mechanism of migraine remains unclear. There are three hypotheses concerning this mechanism i. e. (1) vascular theory, (2) neuronal theory and (3) trigeminovascular theory. The vascular theory was that migrainous headache is due to marked dilatation of cerebral arteries and following activation of perivascular pain-sensitive nerves. In 1980s, many studies to measure regional cerebral blood flow in migraine patients were performed. From these results in some studies, there were much discrepancies from the point of 'classical' vascular theory.
