Psychogenic non-epileptic seizures (PNES) are defined as episodes of altered movements, sensations, and behaviours that resemble epileptic seizures but that are not associated with abnormal electrical brain discharges. The incidence of PNES in the general population is relatively low (about 1.5/100.000 persons per year), but the data from epilepsy centres show a much higher incidence rate. The identification of this pathological entity has significantly increased in the last years, also thanks to the setting-up of video-electroencephalography. The main challenge for physicians and neurologists is to distinguish PNES from epileptic seizures. The aim of this review was to analyse the clinical aspects and the diagnostic problems of PNES in epileptic patients in order to give practical advices for the identification of this problem and for distinguishing PNES from epileptic seizures

Non-epileptik psikojen nöbetler (NEPN), epileptik nöbeti andiran ama anormal elektriksel beyin desarjlari ile iliskili olmayan farkli hareket, his ve davranis ataklari olarak tanimlanir. Genel popülasyonda NEPN insidansi, görece düsüktür (yaklasik yilda 1,5 /100.000 kisi ) ancak epilepsi merkezlerinin verileri çok daha yüksek insidans oranlari göstermektedir. Geçtigimiz yillar içinde bu patolojik durumun tanisi, videoelektroensefalografinin de yardimiyla, anlamli derecede artmistir. Hekimler ve nörologlar için esas sorun NEPN ile gerçek nöbeti ayirmaktir. Bu derlemede; bu problemin tanimlanmasi ve epileptik nöbetlerden ayirici tanisi için, pratik önerilerde bulunmak amaci ile epileptik hastalardaki NEPN’nin klinik yönleri ve tanisal problemleri degerlendirilecektir.
