Psychogenic non-epileptic seizures (PNES).
Psychogenic non-epileptic seizures (PNES) are defined as change in behavior or consciousness resembling epileptic seizures but which have a psychological origin. PNES are categorized as a manifestation of dissociative or somatoform (conversion) disorders. Video-EEG recording of an event is the gold standard for diagnosis. PNES represent a symptom, not the underlying disease and the mechanism of dissociation is pivotal in the pathophysiology. Predisposing, precipitating and perpetuating factors should be carefully assessed on a case-by-case basis. The process of communicating the diagnosis using a multidisciplinary approach is an important and effective therapeutic step.
