  • Title: Computerized EEG topography in childhood migraine between and during attacks.
    Author: Seri S, Cerquiglini A, Guidetti V.
    Journal: Cephalalgia; 1993 Feb; 13(1):53-6. PubMed ID: 8448790.
    Abstract:
    Topographic EEG mapping was performed in 58 migrainous children (mean age: 12.9 years; 39 without, 19 with aura) between attacks. Ten children were also recorded during an attack with visual aura. Between attacks there were no significant differences between migraineurs and age-matched controls. During visual aura a decrease in occipital alpha power contralateral to the affected hemifield was found in all patients. This was followed by a bilateral frontal increase in delta power, and, during the headache, by an increased delta activity in posterior-temporal and occipital electrode sites. The possible brain mechanisms underlying these EEG changes are discussed.
