    Some patients with temporal lobe epilepsy (TLE) continue to have simple partialseizures or auras postoperatively. To scrutinize factors which may correlate withpersistence of auras and to characterize their natural history, we studied 56 TLEpatients who underwent anterior temporal lobectomy after a precise focus determina-tion by long-term intracranial EEG monitoring using bitemporal depth/subduralelectrodes. They were followed for a minimum of 2 years postoperatively. Thirty-onepatients had no postoperative seizures (group 1), 14 patients had auras but no complexpartial seizures (CPSs)(group 2), and 11 patients both auras and CPSs (group 3). Ingroup 2 and 3, history of early brain injury, such as convulsive status, encephalitis andhead trauma was found more frequently; duration of epilepsy was longer and aurasoccurred more frequently than in group 1, preoperatively. Analysis of ictal intracranial EEGs during auras recorded in 18 patients in group 1, 12 in group 2 and 10 in group 3disclosed that ictal discharges, when arising from amygdalo-hippocampal region, wereprone to spread toward the posteromedial structures in group 2 and 3, while in group1 toward anterior basal-temporal area. Auras recurred mostly within a half postoper-ative year in those patients having medial temporal seizure origin and mesial temporalsclerosis, regardless of whether or not CPSs recurred afterwards. Those patientshaving seizures of lateral temporal origin had CPSs as well when they experiencedauras postoperatively. Auras decreased in frequency as years passed. Postoperativepersistence of isolated auras was considered to correlate with a temporomedialepileptogenic zone that extends over posteromedial structures. Nonetheless, the vastmajority of postoperative auras run down.

    A Japanese girl with epilepsia partialis continua (EPC) accompanied by series ofpartial serizures is reported. She developed EPC at age 5 months, and during theensueing month, she also developed a series of partial seizures consisting of flexion ofthe right elbow and rotation of the neck to the right in series at intervals of 8-10seconds for a period of 10 minutes. The series of seizures resembled periodic spasms (PS) first described by Gobbi et al. in 1987, but differed from PS because of its focalmanifestations and ictal EEG showing unilateral high voltage slow waves over thecontralateral hemisphere.
    In EPC, such a peculiar series of partial seizures has not been previously described.However a series of partial seizures can be coexistent with EPC, because EPC andseries of partial seizures are both based on cortical epileptic abnormality.

    We compared twenty-two patients with acute periictal psychosis (P-group) andtwenty-five patients with acute interictal psychosis (I-group) selected from sixhundreds and six epileptics with complex partial seizures or temporal EEG foci.
    The average age at onset of psychotic episodes in P-group (32.1±9.6) wassignificantly older than that in I-group (26.6±7.8). Anxiety aura and dysmnesticseizures were reported significantly more often in P-group than in G-group (x2=4.85, p<0.05). Unilateral sensori-motor seizures tended to be also more intimately associat-ed with P-group. Together with relative predominance of additional frontal EEG-foci, we interpreted this tendency as an evidence of more wide-spread cortical involvementin the P-group.
    Psychopathological characteristics of both groups showed marked difference. Inperiictal psychosis, the commonest pattern of psychopathological findings were rela-tive paucity of primary delusion in contrast with predominance of abnormal moods.This trend was reversed in interictal psychosis. This difference between two groupswas statistically confirmed (p <0.005). In addition, religiosity and sexual disinhibitionwere also psychopathological features of periictal psychosis.

    A well-developed boy developed partial seizures in the right corner of the mouth atthe age of 3 years 1 month, followed by atypical absences at the age of 3 years 7 months. Status epilepticus of atypical absences with blinking and atonic seizures ofthe upper limb and trunk appeared from the age of 3 years 10 months. EEG showeddiffuse sharp-and-slow wave complexes that were maximal in the left C-P-mT-pTarea. Ambulatory EEG recordings were performed for 21.5 hours when he was 4 years 0 month old. Diffuse sharp-and-slow wave complexes appeared in short runs duringwakefulness, and continuously on falling asleep. The occurrence rate of continuoussharp-and-slow wave complexes was 40% during all NREM sleep. Diffuse sharp-and-slow wave complexes were also observed in short runs during REM sleep, anddecreased at awakening in the morning. Percentage of sleep period time for REMsleep was 21% during nocturnal sleep. Prognosis of seizures and mental status wasgood. We diagnosed his disease as ABPE based on the clinical course and the EEGfindings, and discussed the differences from epilepsy with continuous spike-wavesduring slow wave sleep and Lennox-Gastaut syndrome.

    We reported a case admitted to our seizure monitoring unit for the presurgicalevaluation of temporal lobectomy. At the arrival of the auras, this female patientexperienced that happenings actually irrelevant to her such as conversations in thetelevision suddenly became very personal and every word spoken in the surroundingsseemed to be somehow related to her. This excessive “Kohärenz”, namely excessiveintimacy with the surroundings, corresponded to the nondominant anteriorhippocampal seizure discharge in the depth-EEG. This case was also unique becauseof transient manic states following clusters of complex partial seizures. In view of thepredominance of non-dominant origin of seizures in cases with hypomania followingcomlex partial seizures in the literature, we suggested that it deserved intensive studyto examine the precise relationship between this states and laterality of electroence-phalographical ictal discharge.
