A recent study published in Neurology showed that migraine sufferers have thicker gray matter in the part of the brain that perceives pain. Thickening of the gray matter indicates larger number of brain cells in that area, which is not necessarily a bad thing. However, all of the commentary in the media suggests that this is another indication of brain damage in migraine patients. This study is not a cause for alarm and all of the previous research also indicates that the vast majority of migraine sufferers are not at risk of brain damage.
