Are there Brain Differences in People who suffer from Migraines?
A new study found that people with migraines have differences in an area of the brain that helps process sensory information, including pain. The cortex area of the brain is thicker in people with migraine than in people who do not have the neurological disorder. Comparing 24 people with migraine to 12 people without migraine, the study found that the somatosensory cortex area of the brain was an average of 21 percent thicker in those with migraine. “Repeated migraine attacks may lead to, or be the result of, these structural changes in the brain,” said study author Nouchine Hadjikhani, MD, of The Martinos Center for Biomedical Imaging at Massachusetts General Hospital in Boston. “Most of these people had been suffering from migraines since childhood, so the long-term overstimulation of the sensory fields in the cortex could explain these changes.
