Seasonal clustering in epilepsy

Objective:   There are few studies in the literature suggesting that epileptic attacks can cluster especially in winter. We aimed to confirm the most frequent month and season in which our patients with epilepsy visited the emergency room because we had similar observations in our clinical experience. Material and Methods: Patients admitted to the emergency room due to convulsive epileptic seizures between January 2017 and December 2019 were included in the study. The month of seizures was recorded. Results: In our study, epileptic seizures clustered significantly in winter. Conclusion: Although more detailed data should be collected on this subject, we think this is an indirect result of the change in vitamin D metabolism, as suggested in other studies.
