The frequency of EEG abnormalities was significantly high in patients with migraines with auras than other types of headache. Of the 31 patients with abnormal EEGs, 17 showed epileptiform discharges, and 11 showed rhythmic slowing. Results: Of the 259 patients, 31 showed abnormal EEGs, while 228 had normal EEGs. Based on the data entered, analyses of the following items were conducted: (1) comparison of the EEG abnormalities by the type of headache and the characteristics of the EEG findings and (2) comparison of the clinical characteristics between patients with normal and abnormal EEGs. Methods: We conducted a retrospective analysis reviewing the medical records of 259 patients with headaches who visited the pediatrics departments of five university hospitals and underwent EEGs over a period of 3 years. The aim of our study was to evaluate the EEG characteristics by the type of headache and the implications of EEGs in headache patients, comparing the clinical characteristics and treatments between the headache patients with normal and abnormal EEGs. Introduction: Epilepsy and migraines are frequently observed as comorbidities, with the occurrence of one disorder increasing the probability of the other. 5Department of Pediatrics, College of Medicine Chonnam National University, Gwangju, South Korea.4Department of Pediatrics, College of Medicine, Pusan University, Busan, South Korea.3Department of Pediatrics, College of Medicine, Yonsei University, Seoul, South Korea.2Department of Pediatrics, College of Medicine, Hallym University, Chuncheon, South Korea.1Department of Pediatrics, College of Medicine, Chosun University, Gwangju, South Korea.
