[Electroencephalographic studies in migraine].
The author reviews the pertinent literature and the results of own investigations in migraine. EEG changes in migraine are observed in nearly 50% of cases during attacks as well as in the periods free of pains. Most investigations were done in the periods between attacks. The H response characteristic of migraine was found by the author in 25% of cases only. Focal changes were present in 30% of cases. They were not related to the side of the pain, its duration and the form of migraine. Seizure activity was never observed. The author regards isolation of the so-called dysrhythmic form of migraine as not justified. EEG changes suggest--according to the author--that migraine is a primary cerebral and only secondarily a vascular disorder.
