Most variables, except for antipsychotic drugs administered, not associated episodes. Several characteristics, i.e., history interictal psychosis, family functioning, Conclusions: This study showed most last less than appear to be prolonged when individuals have an underlying vulnerability psychosis. Clinical phenomena can trigger may determine course episode. Ke yW ords: Epilepsy—Postictal psychosis— Duration—Time course—Clinical characteristics.
