Basilar Migraine with Electroencephalographic Findings of Occipital Spike-Wave Complexes: A Long-Term Study in Seven Children

Basilar migraine is characterized by headache preceded by prodromal symptoms and signs of posterior cerebral circulation dysfunction. Few studies have focused on EEG findings in this condition or on the prognosis of occipital spike-wave complexes observed in either migraine or epilepsy. We now report a long-term follow-up (8–16 years) in seven children affected by basilar migraine who had EEG findings of occipital spike-wave complexes. Basilar migraine resolved and the EEG became normal in all subjects during the observation period, as did migraine with aura and seizures which developed in some of the patients after basilar migraine attacks ceased.
