Long-term safety and efficacy of adjunctive lacosamide in the treatment of generalized onset tonic-clonic seizures: An open-label extension trial.

Objective: This study was undertaken to assess long-term safety, tolerability, and efficacy of lacosamide (LCM) as adjunctive therapy for generalized onset tonic-clonic seizures (GTCS) in patients aged ≥4 years with idiopathic generalized epilepsy (IGE).

Methods: EP0012 (NCT02408549) was a phase 3, multicenter, open-label extension (OLE) trial. Patients were enrolled from SP0982 (NCT02408523).

Classification of transient epileptic amnesia attacks: Two types of amnestic seizures, the pure amnesia type and partial amnesia type.

Aim: Transient epileptic amnesia (TEA) is a type of mesial temporal lobe epilepsy characterized by recurrent amnesia attacks. In 1998, Zeman et al. proposed the following diagnostic criteria for TEA: (1) recurrent, witnessed episodes of amnesia (TEA attacks); (2) other cognitive functions remain intact during attacks; and (3) evidence of epilepsy.

Risk factors for psychological distress in electroencephalography technicians during the COVID-19 pandemic: A national-level cross-sectional survey in Japan.

Objective: To identify the risk factors for psychological distress in electroencephalography (EEG) technicians during the coronavirus disease 2019 (COVID-19) pandemic.

Method: In this national-level cross-sectional survey initiated by Japan Young Epilepsy Section (YES-Japan), which is a national chapter of The Young Epilepsy Section of the International League Against Epilepsy (ILAE-YES), a questionnaire was administered to 173 technicians engaged in EEG at four clinics specializing in epilepsy care and 20 hospitals accredited as (quasi-) epilepsy centers or epilepsy training facilities in Japan from March 1 to April 30, 2021. We collected data on participants' profiles, information about work, and psychological distress outcome measurements, such as the K-6 and Tokyo Metropolitan Distress Scale for Pandemic (TMDP).

A proposal for a new clinical entity: transient epileptic amnesia complex syndrome (TEACS).

Transient epileptic amnesia (TEA) is a special type of temporal lobe epilepsy, the main symptom of which is recurrent amnesia attacks. In the late 1990s, Zeman et al. developed the following diagnostic criteria for TEA: (i) recurrent, witnessed episodes of amnesia; (ii) other cognitive functions remain intact during attacks; and (iii) evidence of epilepsy.

Efficacy and safety of adjunctive lacosamide in the treatment of primary generalised tonic-clonic seizures: a double-blind, randomised, placebo-controlled trial.

Objective: To evaluate efficacy and safety of lacosamide (up to 12 mg/kg/day or 400 mg/day) as adjunctive treatment for uncontrolled primary generalised tonic-clonic seizures (PGTCS) in patients (≥4 years) with idiopathic generalised epilepsy (IGE).

Methods: Phase 3, double-blind, randomised, placebo-controlled trial (SP0982; NCT02408523) in patients with IGE and PGTCS taking 1-3 concomitant antiepileptic drugs. Primary outcome was time to second PGTCS during 24-week treatment.

The self-stigma of patients with epilepsy in Japan: A qualitative approach.

The mental health of patients with epilepsy represents a substantial public health concern in Japan. For instance, the Japanese term for epilepsy, "tenkan", has the negative meaning of "mad" and "a violent temperament that is apt to be infatuated". Although epilepsy is now understood as a disease caused by abnormal neuronal activity in the brain, discrimination and stigma against people with epilepsy remain deeply rooted in Japanese culture.

Multinodular and vacuolating neuronal tumor (MVNT): A presumably incidental and asymptomatic case in an intractable epilepsy patient.

Introduction: Multinodular and vacuolating neuronal tumor (MVNT) had been initially described as an epilepsy-related brain tumor, but recent studies demonstrated it could be found incidentally in non-epilepsy patients.

Case Report: A 33-year-old woman with intractable post-encephalitis epilepsy presented a cluster of multinodular T2 hyperintensity in the left temporal lobe, which was very similar to the characteristics of MVNT. Long-term video electroencephalogram demonstrated that the habitual seizures were originated from bilateral temporal area and the interictal epileptic discharges were seen multifocally, although the lesions with MVNT appearance were localized in the left temporal lobe.

Nationwide survey in Japan endorsed diagnostic criteria of benign adult familial myoclonus epilepsy.

Purpose: Benign adult familial myoclonus epilepsy (BAFME) is an autosomal dominant disease representing tremulous myoclonus or cortical tremor and infrequent generalized seizures. We aimed to delineate detailed epidemiological backgrounds in patients with Japanese BAFME and to establish diagnostic criteria based on clinical and electrophysiological findings.

Methods: After a previous survey on the current nationwide state of myoclonus epilepsy of adults in Japan, we conducted this survey to delineate the clinical characteristics of Japanese BAFME patients, using a questionnaire to obtain details for individual patients.
