Rx response = treatment response (+ = abolition or substantial reduction of episodes, E = equivocal reduction, CBZ = carbamazepine, P = phenytoin, SVP = sodium valproate, OXZ = oxazepam, surg = surgery); other epilepsy = other co-occurring seizure types, (sps = simple partial seizures, cps = complex partial seizures, tcl = tonic-clonic seizures); TEA aura = occurrence of co-occurring seizure type as prodrome of amesic episode, (+ = co-occurring seizure type always precedes TEA, +/− = co-occurring seizure type sometimes precedes TEA, − = no co-occurring seizure type); Imp mem = complaint of impaired memory not further specified; vis/verb = deficits on tests of anterograde visual/verbal memory; ant = anterograde memory impairment not further specified; retro = deficits on tests of retrograde memory.
