Migraines can be a common complaint from stressed adults but doctors said the condition may be a result of a brain abnormality at birth.
Italian researchers had 63 migraine patients and 18 people with no history of headaches undergo brain scans.
They found that the migraine sufferers had a reduced surface area of the outer layer of the brain.
Those patients also had reduced thickness of the cortex, which changes during a person’s lifespan.
Both of those abnormalities were in the pain processing areas of the brain.
