Psychogenic non-epileptic seizures are a manifestation or a form of conversion isorder. They take many forms, and particularly can mimic any sort of epileptic seizure; they are distinguished from epilepsy only in that they are not associated with abnormal, rhythmic discharges of cortical neurons. The condition is not benign; people have broken bones, crashed automobiles, bitten off parts of their tongue, and even died from injuries sustained during non-epileptic seizures.
