The topographic maps of 100 patients with various types of headache (classic migraine, non-classic migraine, muscle contraction, mixed and post-traumatic) were compared to the brain maps of 38 normal controls. Patients with classic migraine showed 11 markers, but especially three of high amplitude theta on 0(1) and alpha on 0(1) and T6, thereby identifying 82% of the patients with only 30% as false positives. Patients with other types of headaches in general did not show useful markers.
