Psychogenic nonepileptic seizures: A case series.

Manifestation of abnormal excessive synchronous cortical activity, which is what defines epileptic seizures, is typically absent in seizures with psychological etiology, a heterogeneous set of factors that have been identified. Distinguishing psychogenic nonepileptic seizures (PNES) from epileptic seizures may be difficult at the bedside. We report a case series of PNES which presented with diagnostic dilemma. Diagnostic delay of years with PNES is common. The exact choice of treatment is often difficult and should be based on individual differences in the underlying factors. Outcome can be measured in terms of seizure occurrence (frequency, severity), but other measures might be of greater importance for the patient. Prognosis is varied but studies consistently report that 1/3 to 1/4 of these cases become chronic.
