Decreased electrodermal activity in patients with epilepsy.

Objective: Biofeedback therapy using electrodermal activity (EDA) is a new noninvasive therapy for intractable epilepsy. However, the characteristics of EDA in patients with epilepsy are little known; therefore, we assessed the EDA characteristics in patients with epilepsy.

Methods: A cross-sectional observational study was conducted in 22 patients with epilepsy and 24 healthy individuals.

Seizure manifesting as a reaching/grasping movement in a patient with post-traumatic epilepsy.

Electrical stimulation (ES) of the pre-supplementary or cingulate motor area can cause reaching/grasping (R/G) movements with the hand contralateral to the side of the brain receiving the ES. We report this phenomenon occurring in a 23-year-old right-handed man during spontaneous epileptic seizure, which developed after traumatic brain injury.

Very Long-Term Outcome of Non-Surgically Treated Patients with Temporal Lobe Epilepsy with Hippocampal Sclerosis: A Retrospective Study.

Objective: Surgical intervention can result in complete seizure remission rates of up to 80% in patients with temporal lobe epilepsy with hippocampal sclerosis (TLE-HS). However, certain patients cannot be treated surgically for various reasons. We analyzed the very long-term clinical outcomes of patients with TLE-HS who could not be treated surgically.

Video event data recording of a taxi driver used for diagnosis of epilepsy.

A video event data recorder (VEDR) in a motor vehicle records images before and after a traffic accident. This report describes a taxi driver whose seizures were recorded by VEDR, which was extremely useful for the diagnosis of epilepsy. The patient was a 63-year-old right-handed Japanese male taxi driver.

Pilomotor seizures in temporal lobe epilepsy: A case report with sequential changes in magnetic resonance imaging.

Piloerection is a rare ictal manifestation of temporal lobe epilepsy. The case is a 38-year-old man with acute onset of repetitive pilomotor seizures. Lacking other symptoms implicating epileptic seizures, a month passed before he was diagnosed with epilepsy.

Akinetopsia as epileptic seizure.

Akinetopsia is a rare syndrome in which a patient specifically loses the ability to perceive visual motion following bilateral cortical lesions outside the striate cortex. We describe a patient who showed akinetopsia recurrently as epileptic seizures. The patient was a 61-year-old man.

A patient who misidentified all surrounding persons as her family.

This report describes a patient who misidentified all surrounding persons as her family after a cerebral hemorrhage in the right temporal lobe. She had no difficulty with visual face recognition. Single-photon emission computed tomography revealed hyperperfusion in the right amygdala and hippocampus.

Persistent déjà vu associated with hyperperfusion in the entorhinal cortex.

Déjà vu is a common experience among the normal population. However, in individuals with temporal lobe epilepsy, it often occurs as a seizure manifestation. The specific cause of such déjà vu is not yet known.

[Case report of anti-NMDA receptor encephalitis suspected of schizophrenia].

Recently, paraneoplastic encephalitis associated with ovarian teratoma, which predomi nantly affects young women, has been reported. Its symptoms are severe but often treatment-responsive and reversible. Various psychiatric symptoms occurring shortly after onset are characteristic of this encephalitis.

Generalized spike-wave discharges involve a default mode network in patients with juvenile absence epilepsy: a MEG study.

This study uses magnetoencephalography (MEG) to examine whether cortical regions that constitute a default mode network are involved during generalized spike-wave discharges (GSWs) in patients with juvenile absence epilepsy (JAE). We studied five JAE patients for whom MEG was recorded using a 204-channel, whole-head gradiometer system. Dynamic statistical parametric mapping (dSPM) was done to estimate the cortical source distribution of GSW.

Magnetoencephalographic studies of focal epileptic activity in three patients with epilepsy suggestive of Lennox-Gastaut syndrome.

Purpose: To determine the electromagnetic sources of localized epileptic activities using magnetoencephalography (MEG) in three adult patients with epilepsy suggestive of Lennox-Gastaut syndrome (LGS).

Methods: MEG and simultaneous electroencephalography (EEG) were recorded from three adult patients using a 204-channel, whole-head MEG system. Equivalent current dipoles (ECDs) were calculated for epileptic spikes on MEG according to the single dipole model.

Neuromagnetic source localization of epileptiform activity in patients with graphogenic epilepsy.

Purpose: To clarify the source localization of epileptiform activity by using magnetoencephalography (MEG) in patients with graphogenic epilepsy.

Methods: MEG and simultaneous EEG were recorded with a 204-channel whole-head MEG system in two patients with graphogenic epilepsy. During the MEG recordings, the patients performed a set of tasks comprising mental arithmetic calculation, speaking, moving the right arm in a manner resembling writing, writing, and thinking of writing.

Magnetoencephalographic analysis of secondary bilateral synchrony.

To assess the clinical value of magnetoencephalography (MEG) in investigating the origin of secondary bilateral synchrony (SBS) in patients with partial epilepsy. MEG and simultaneous electroencephalography (EEG) were recorded with a 204-channel whole-head MEG system in 2 patients. The equivalent current dipoles (ECDs) for epileptic discharges on MEG were calculated according to a single dipole model.
