People with migraine structural differences in the brain, particularly in the area of the cortex that processes pain and other sensory information from the body, scientists say.
The researchers, whose findings were published in the journal Neurology, said it is unclear whether these brain differences actually cause migraines or are caused by these severe headaches and recurrent.
The researchers performed brain scans on 24 people who had a history of frequent migraines, about four per month for 20 years, and 12 people without migraine.
The somatosensory cortex - the area of the brain that detects sensations like pain, touch and temperature in different parts of the body - 21% thicker in people who got migraines compared to those who don 'no.
The biggest difference was the shell is responsible for processing sensory information of the head and face, said Dr. Hadjikhani Nouchine and Massachusetts General Hospital, who led the study.
Hadjikhani said the study illustrates the severity of migraines.
"It 'to be taken seriously, because it can cause changes in the brain," he says.
Migraine is a kind of painful headache often accompanied by nausea, vomiting and increased sensitivity to light and sound.
Women are three times more likely than men to experience these headaches. Many people who have them is a family history of migraine.
"The more we understand about the pathophysiology of migraine, the better we will be able to design drugs that work. There is currently no drug for prevention that works well," Hadjikhani said.

Dr. David Dodick, a professor of neurology at the Mayo Clinic, who is not involved in the study, said the study shows that migraine is a brain disease.
"And it shows that migraine has a durable, long-term structural or morphological changes in the brain over time," he said.
Dodick said he would be interested in whether people who receive less frequent migraines that the same brain changes.
Hadjikhani said one possibility is that repeated, long-term ovarian sensory fields in the cortex may cause the thickness of the time.
Another possibility is that people predisposed to migraines already have this thicker cortex, Hadjikhani said.
According to U.S. National Institute Health, researchers suspect that migraines are caused by inherited abnormalities in genes that control certain brain cells.
For many years, scientists had thought migraines associated with the expansion and contraction of blood vessels in the head.
Dr. Seymour Diamond, executive chairman of the U.S. National Headache Foundation, says the results also confirm that migraine is a neurological disease.
The researchers also found differences in cortical thickness in other diseases.
It is thinner, for example in people with multiple sclerosis, Alzheimer's disease and autism.
