Euphoria may occur during auras of seizures   typically originating in the temporal lobe , but effecting the anterior insular cortex . This euphoria is symptomatic of a rare syndrome called ecstatic seizures,   often also involving mystical experiences .  Euphoria (or more commonly dysphoria ) may also occur in periods between epileptic seizures. This condition, interictal dysphoric disorder , is considered an atypical affective disorder .   Persons who experience feelings of depression or anxiety between or before seizures occasionally experience euphoria afterwards.
