title: [Chronoelectroencephalographic studies in migraine and related headaches].
abstract: The authors conducted periodic electroencephalographic (chrono-EEG) investigations in 64 subjects including 48 with various vasomotor headaches and 16 healthy ones. Chrono-EEG investigations carried out at different times of the day during wakefulness in healthy subjects and patients with Horton's (cluster) headaches showed lack of changes of the biochemical activity of the brain. In the group of patients with common vasomotor headaches the background activity was labile and evidence of decreased wakefulness was found in evening hours. In patients with migraine two patterns of chrono-EEG curves were elicited; normal an significantly activated at noon and during evening hours. The obtained results of these investigations seem to suggest a lack of uniformity of the pathomechanism of migraine. Further investigations have been started.
