MRI scans show Migraines are linked to brain abnormalities at birth, and others that develop over time.
Italian researchers had 63 migraine patients and 18 people with no history of headaches undergo brain scans. They found migraine sufferers had a reduced surfaced area of the outer layer of the brain or cortex which forms in the womb.
They also had a reduced thickness of the cortex, which changes during a person's lifespan and is affected by disease.
Both of these abnormalities were in the pain processing areas of the brain.
