Alpha rhythm power and the effect of photic stimulation in migraine with brain mapping
Clinical EEG (Electroencephalography)
|January 1, 1992
Abstract:
The topographic maps of 50 patients suffering from migraine with or without aura were compared to the brain maps of 20 normal controls and 20 patients with tension-type headaches. Only the migraine group showed a significant decrement of alpha rhythm power, during rest with eyes closed, at the posterior areas of the brain, and a significant increment of alpha power at the same regions during IPS at 20 c/sec.
