Electroencephalography (EEG) is the recording of the electrical activity of the brain. EEG is a reliable test to assess cerebral function. It aids in diagnosis, classification, and management of patients with epilepsy. It also has practical uses in conditions other than epilepsy. Moreover, it is harmless and inexpensive. EEG is an important tool for evaluating patients with epilepsy. It may help classify the syndrome, identify the likely source of focal seizures, and confirm a diagnosis of status epilepticus...

We describe a case of ictal asystole in a patient with posterior reversible encephalopathy syndrome (PRES), which has never been described previously. Ictal asystole is rare and has possible serious medical consequences, including syncope, and may be a potential mechanism for sudden unexpected death in epilepsy (SUDEP). Awareness that PRES may be observed with recurrent ictal asystole may aid in the recognition and treatment of seizures in this condition and the prevention of asystole-associated complications...

Epilepsy is difficult to diagnose using routine EEG recordings of short duration in patients who have low seizure frequency. Long-term EEG may be useful but is impractical in an out-of-hospital setting. We investigated whether single-channel scalp EEG placed behind the earlobe is suitable for seizure identification during prolonged EEG monitoring. Scalp EEG samples were selected from subjects over 15 years of age, and comprised two segments of either background followed by seizure or background followed by background...

Vagus nerve stimulation (VNS) is an established option of adjunctive treatment for patients with drug-resistant epilepsy, however, evidence for long-term efficacy is still limited. Studies on clinical outcomes of VNS in Asia are also limited. We report the overall outcome of a national, prospective registry that included all patients implanted in Japan. The registry included patients of all ages with all seizure types who underwent VNS implantation for drug-resistant epilepsy in the first three years after approval of VNS in 2010...

Atonic seizures are common in some epileptic syndromes beginning in infancy or early childhood but they are rarely described in epilepsy with focal seizures of structural aetiology. We aimed to characterize the electroclinical features of atonic seizures in surgically remediable paediatric patients and to study the spatiotemporal organization of the underlying epileptogenic networks. We retrospectively analysed two consecutive, longitudinally evaluated and surgically treated paediatric patients presenting with atonic seizures as a manifestation of pharmacoresistant epilepsy of structural aetiology, evidenced by scalp- and stereotactic intracerebral video-EEG-recordings...

We report the case of an infant with KCNQ2-related neonatal epileptic encephalopathy presenting with intractable seizures beginning on the second day of life, which were resistant to multiple antiepileptic drugs. Continuous EEG recordings starting on the sixth day of life demonstrated a unique pattern of inter-and postictal focal rhythmic pointed theta waves of lambdoid morphology in the immediate postictal period, localizing to the side of the antecedent seizure. Interictal EEG exhibited discontinuous background, including patterns of burst suppression and multifocal discharges, predominantly in the centrotemporal regions, which were aggravated during sleep...

Epileptic encephalopathies with continuous spike-and-waves during sleep (CSWS) are characterized by cognitive or language impairment, and are occasionally associated with pathogenic variants of the GRIN2A gene. In these disorders, speech dysfunction could be either related to cerebral dysfunction caused by the GRIN2A deleterious variant or intense interictal epileptic activity. Here, we present a patient with apraxia of speech, clearly linked to severity of epilepsy, carrying a GRIN2A variant. A 6-year-old boy developed acute regression of expressive language following epileptic seizures, leading to complete mutism, at which time EEG revealed CSWS...

Ictal aggressive behaviour is a rare manifestation of focal seizures. We report an episode of ictal aggression occurring during an intracerebrally recorded seizure (using stereoelectroencephalography) in a patient with drug-resistant temporal lobe epilepsy. Aggression occurred during the last part of the seizure and was coincident with marked EEG slowing of the frontal regions and persistent ictal activity in the medial temporal lobe. A functional connectivity study (h(2) estimation of interdependencies) showed a bilateral massive hypersynchronization between frontal and temporal regions...

We report a 37-year-old, right-handed patient with drug-resistant focal epilepsy whose seizures were characterized by explosive hyperkinetic behaviour. Video-SEEG revealed bifocal organization of epilepsy with two distinct cortical origins of seizures: the right temporal pole and left temporal lateral and perisylvian cortex. Irrespective of the cortical pattern of seizure onset, the hyperkinetic semiology was extremely similar. This supports a major role for "final common pathway" subcortical circuits in the genesis of the hyperkinetic semiology in this patient...

The WW domain-containing oxidoreductase gene is implicated in autosomal recessive disorders of the central nervous system, expressed either as spinocerebellar ataxia or as a severe form with early-infantile epileptic encephalopathy. Here, we describe the electroclinical evolution of these disorders, adding new diagnostic clues based on a case study. The patient, a boy with early-onset epilepsy, presented with profound global developmental delay, persistent hypsarrhythmia, and epileptic spasms, associated with progressive cerebral atrophy without microcephaly...

To evaluate the sensitivity and specificity of quantitative EEG (QEEG) spectrograms in order to distinguish epileptic from non-epileptic events. Seventeen patients with paroxysmal non-epileptic events, captured during EEG monitoring, were retrospectively assessed using QEEG spectrograms. These patients were compared to a control group of 13 consecutive patients (ages 25-60 years) with epileptic seizures of similar semiology. Assessment of raw EEG was employed as the gold standard against which epileptic and non-epileptic events were validated...

Transient lesions of the splenium of the corpus callosum are characterized by MRI findings. The lesions are very rare, but significant from a clinical standpoint as differential diagnoses include serious conditions such as encephalitis, meningitis, and neuroleptic malignant syndrome. In addition, it is reported that some are attributed to the withdrawal of antiepileptic drugs. Here, we present a case of transient lesions of the splenium of the corpus callosum following rapid withdrawal of levetiracetam alone...

SYNGAP1 gene mutation has been associated with epilepsy which is often drug resistant, with seizure types including eyelid myoclonia. However, detailed descriptions, including ictal video-EEG, have not been reported. We report the case of a 4-year-old boy who developed recurrent epileptic eyelid twitching at 1 year and 5 months of age. Seizures gradually increased in frequency to more than 50 times per day and manifested with upward eye deviation, motion arrest, loss of consciousness, and eyelid twitching lasting for five seconds...

Some patients with temporal lobe epilepsy have bilateral discharges and a few have bilateral medial temporal sclerosis. Stereotactic bilateral radiofrequency thermocoagulation (RFTC) of the amygdalohippocampal complex can terminate seizures or reduce seizure severity in patients with bilateral medial temporal lobe epilepsy (BMTLE). To explore the safety and efficacy of bilateral transfrontal minimal RFTC of the amygdalohippocampal complex for the treatment of BMTLE. A total of 12 BMTLE patients were treated with bilateral transfrontal minimal RFTC of the amygdalohippocampal complex under limited coagulations...

In this description of the clinical course of a young female with persistent and protracted vomiting along with occasional loss of consciousness and subtle motor manifestations, the differential diagnosis is debated. The epileptic origin of her symptoms was substantiated by the presence of interictal epileptiform discharges and dramatic response to valproate monotherapy. Possible lobar localizations are discussed with the support of existing literature on this rare ictal manifestation [Published with video sequence on www...

To evaluate the safety and effectiveness of lacosamide in a real-life setting with the use of a flexible dose titration schedule and individualised maintenance doses up to the maximum approved dose of 400 mg/day. Adults with a diagnosis of focal seizures, with or without secondary generalization, were enrolled in this open-label Phase IV trial (NCT01235403). Lacosamide was initiated at 100 mg/day (50 mg bid) and uptitrated over a 12-week period to 200, 300 or 400 mg/day, based on safety and seizure control...

Reports on the clinical presentation of adult-onset neuronal ceroid lipofuscinoses (NCL) are scarce compared to infantile- and childhood-onset forms. Here, we aimed to present detailed temporal evolution of clinical and electrophysiological features of two siblings with adult-onset NCL and homozygous mutation in the CLN6 gene. We retrospectively analysed medical records and electrophysiological data in order to delineate evolution of clinical and electrophysiological findings. Electrophysiological studies included routine EEG and video-EEG, as well as polymyographic analysis of myoclonus and brainstem reflex studies...
