Maurizio Gabrielli, MD and colleagues studied 90 patients who were diagnosed with idiopathic migraine, and found that 4.4% had celiac disease compared to 0.4% of 23 controls. The four migraine patients found to have celiac disease were treated for six months with a gluten-free diet and their symptoms decreased or were eliminated. The patients also showed an improvement in their cerebral blood flow on a gluten-free diet that was confirmed by using single-photon emission computed tomography scans.
