The Role of Orexin-A Levels in Epileptic Seizure.

•Epileptic seizures are often confused with psychogenic non-epileptic seizures.•True diagnoses often come late in psychogenic non-epileptic seizures patients.•Delay in diagnostic procedures can cause patients to unnecessarily use many antiepileptic drugs Therefore, it is important to establish the differential diagnosis of epilepsy and non-epileptic seizures patients in the early period.•Blood orexin levels may be an effective biomarker in the differential diagnosis of epileptic seizures and non-epileptic seizures patients.
