Abstract

Migraine is associated with a variety of electroencephalographic (EEG) changes. Previous studies using analogue EEG and old diagnostic criteria may under or over report the prevalence of EEG changes in migraine. The objective of this study was to reevaluate the EEG changes in migraine patients diagnosed by applying the new International Classification of Headache Disorder -2 criteria. This was a case control study involving 70 migraine patients and 70 age and gender matched control who were subjected to scalp EEG. The EEG changes during hyperventilation (HV), which were significantly more common in the migraine group were theta activity (34 vs 22, p = 0.038) and frontal intermittent rhythmic delta activity (FIRDA) (10 vs 3, p = 0.042). Applying the new ICHD -2 diagnostic criteria and digital EEG, this study yielded previously unrecognized features including FIRDA during HV on EEG.
