The character and extent of EEG-changes in 40 patients with migraine accompagnée and 41 patients with classical migraine were studied and the EEG-diagnoses of both groups were compared. Moreover, the EEG-diagnoses in these patients were compared in relation to a control-group. The EEG showed pathological findings in 10 patients (83%) during the attacks and in 39 patients (57%) during the intervals with predominating focal changes (51%). Patients with migraine accompagnée had more frequently pathological findings (70%) as well as focal changes (60%) than patients with classical migraine (51% respectively 41%). The persistence of disturbances in patients with migraine accompagnée was longer than in patients with classical migraine. In comparison to the controls a significantly more frequent occurrence of pathological results was found in patients with migraine accompagnée and classical migraine during the attack as well as during the interval. The age of patients, duration of the migraine and frequency of attacks did not influence the extend of EEG changes. The EEG revealed in patients with migraine significantly more frequent functional disturbances than in controls, which were more pronounced in patients with migraine accompagnée and during the attacks.
