Abstract: The purpose of this study was to investigate the timing of generalized electroencephalographic abnormalities in patients with juvenile myoclonic epilepsy who were followed up long term before the onset of juvenile myoclonic epilepsy. We enrolled juvenile myoclonic epilepsy patients whose course of epilepsy had been

Aim: Juvenile Myoclonic Epilepsy (JME) is predominantly observed during adolescence, characterized by myoclonic jerks exacerbated by sleep deprivation. Generalized tonic-clonic (gtc) and absence seizures are also common in JME. Patients are often photosensitive and usually require long-term treatment. This study aims to retrospectively evaluate the clinical, demographic, and electroencephalography (EEG) findings of patients diagnosed with JME at our Pediatric Neurology Clinic. Methods: Patients who were followed up at Department of Pediatric Neurology between 2017-2022, diagnosed with JME based on clinical and EEG findings, and had at least one year of follow-up were included in this study. The clinical characteristics of the patients, as well as their diagnostic and follow-up EEG results, were retrospectively reviewed. Results: Of the patients, 12 (55%) were female and 10 (45%) were male. The mean age of the patients was 17±1 (range 14-18) years, and the average age at first seizure was 13±2 (range 12-16) years. When examining the types of seizures in our cases; 12 (55%) had myoclonic and gtc seizures, 4 (18%) had a combination of myoclonic-gtc-absence, and 6 (27%) had isolated myoclonic seizures. EEG results showed that 6 (27%) of the patients had spike and multiple spike waves at 3-5.5 Hz during sleep, while the remaining 16 (73%) had these during wakefulness. Fourteen (64%) of the patients responded to photic stimulation. Six (27%) of the patients had a first-degree relative with a history of epilepsy. A significant association was found between the presence of photosensitivity and family history about epilepsy (p=0.03). Conclusion: Juvenile myoclonic epilepsy is a type of epilepsy observed in the adolescent period, characterized by myoclonic jerks and photosensitivity. The presence of family history regarding epilepsy can be a indicator for photosensitivity.
