Psychogenic non-epileptic seizures: a concise review Ali A. Asadi-Pooya (USA, Iran) DOI 10.1007/s10072-017-2887-8 Psychogenic non-epileptic seizures (PNES) are commonly diagnosed and treated at epilepsy centers; however, their neurobiology is still poorly understood. Diagnosis relies on a multidisciplinary evaluation and is usually based on different combinations of data. They are diagnosed most reliably by recording a seizure while under video-EEG monitoring. Treatment includes multiple phases. Fewer than 40% of adults with PNES are expected to become seizure-free within 5 years after diagnosis. This article presents a concise review of the current literature about the definition, diagnosis, epidemiology, clinical characteristics, treatment, and prognosis of PNES.
