Electroencephalographic (EEG) changes in migraine patients: a comparative analysis of aura and non-aura migraine with chronic tension-type and medication overuse headaches

This study explores electroencephalographic (EEG) changes in patients with different types of chronic headaches, including aura and non-aura migraine, chronic tension-type headaches, and medication overuse headaches. The research analyzes EEG parameters such as dominant alpha rhythm, slow-wave activity, focal theta and delta rhythms, and hemispheric asymmetry during and outside migraine attacks. The findings indicate significant neurophysiological differences among headache types, which could aid in refining diagnostic criteria and developing personalized treatment strategies. The study also highlights the relationship between cognitive dysfunction and EEG alterations in migraine patients.
