Those with the misfortune to suffer regular migraines should know that those headaches aren't just knocking them off their feet—they seem to be causing physical changes to the brain, reports AFP. Researchers say that migraine sufferers, especially those who experience symptoms such as sensitivity to light and dizziness in advance, are more likely to have brain lesions and other abnormalities of brain tissue.
"Traditionally, migraine has been considered a benign disorder without long-term consequences for the brain," says one of the Copenhagen researchers. "Our review and meta-analysis study suggests that the disorder may permanently alter brain structure in multiple ways." This may sound worse than it actually is, however. The scientists aren't saying the abnormalities necessarily cause problems, only that they're more common in migraine patients, reports HealthDay News. "I do not think the patient should be concerned, but treatment and control of migraine is recommended," says that same researcher.
