Migraines Linked to Varied Arterial Structures of the Brain, Study Says

In migraine sufferers, the network of arteries supplying blood to the brain is more likely to be incomplete than in those who do not suffer from migraines. The finding, appearing in PLOS ONE, suggests that migraines can be triggered by asymmetries in cerebral blood flow caused by variations in arterial structures. “People with migraine actually have differences in the structure of their blood vessels – this is something you are born with,” one investigator said.  “These differences seem to be associated with changes in blood flow in the brain, and it’s possible that these changes may trigger migraine, which may explain why some people, for instance, notice that dehydration triggers their headaches.” Click here to read the full article.
