ABSTRACT
Twenty women with migraine were evaluated by EEG coherence analysis. In comparison with controls, the migrainous subjects showed lower interhemispheric coherence values at C3-C4 for the delta band (P=0.0030) and at F3-F4 (P=0.0055) and C3-C4 (P=0.0018) for the beta band frequency (Wilcoxon criterion). In contrast, 22 intrahemispheric coherence pairs were significantly higher in the migraine group than in the control group (P<0.01). The subjects with visual aura showed lower interhemispheric coherence at O1-O2 and T5-T6 for the alpha band than the subjects without the aura. Discriminant analysis revealed that 95% of the subjects with migraine and 85% of the controls were correctly classified into their proper groups. We suggest that EEG coherence analysis is a sensitive parameter in the detection of electrophysiological abnormalities in patients with migraine.
