Migraine Incidence and Brain Artery Abnormality

Blood vessels are once again suspected as causal factors in the incidence of migraine, although new research suggests in a different role than previously thought. It was once believed that vessel dilation was involved, but a new study appearing in PLOS ONE suggests that structural abnormalities in the network of arteries supplying blood flow to the brain is a more likely contributor. Specifically, it was found that people with migraine, particularly migraine with aura are more likely to exhibit missing components in the series of connections between arteries known as the “circle of Willis”.
