Awareness and driving safety during awake interictal epileptiform discharges in idiopathic generalised epilepsies: A systematic review.

Idiopathic generalised epilepsies (IGEs) are a family of epileptic syndromes that commonly occur in childhood or adolescence and can persist into adulthood. Whilst people with IGE may consider themselves seizure free, they often experience interictal epileptiform discharges (IEDs) that may be associated with unrecognised periods of impaired awareness. As such, the presence of long IEDs associated with unrecognised loss of awareness pose a major challenge in allowing these individuals to drive safely, particularly since not all IEDs are associated with impaired awareness.

Neuronal complexity tracks changes of epileptic activity and identifies epilepsy patients independent of interictal epileptiform discharges.

Objective: To date, the identification of objective biomarkers of neural epileptic activity (EA) remains challenging. We therefore investigated whether neuronal complexity could serve as an interictal electroencephalographic measure of EA, independent of interictal epileptiform discharges (IEDs). By tapering anti-seizure medication (ASM) during video-EEG (electroencephalography) monitoring (VEM), we studied whether changes in neuronal complexity could reliably indicate the increase in EA and identify patients with epilepsy.

Plasma microRNAs as prognostic biomarkers for development of severe epilepsy after experimental traumatic brain injury-EpiBioS4Rx Project 1 study.

Objective: To test a hypothesis that acutely regulated plasma microRNAs (miRNAs) can serve as prognostic biomarkers for the development of post-traumatic epilepsy (PTE).

Methods: Adult male Sprague-Dawley rats (n = 245) were randomized to lateral fluid-percussion-induced traumatic brain injury (TBI) or sham operation at three study sites (Finland, Australia, United States). Video-electroencephalography (vEEG) was performed on the seventh post-injury month to detect spontaneous seizures.

Combining three-phase EEG pattern and ipsilateral isolated eye deviation to predict seizure focus in the frontal interhemispheric fissure.

Objective: Identification of seizure focus on the interhemispheric fissure (IHF) is often challenging at the step of scalp video-EEG monitoring on preoperative evaluations. We previously reported ictal three-phase EEG patterns (3Ph-EEG) and isolated eye deviation (isolated ED) to side of the seizure focus during seizures, each of which is available for identifying the seizure focus for frontal IHF (F-IHF). This study aimed to evaluate the accuracy of predicting the F-IHF focus using a combination of 3Ph-EEG and isolated ED in patients with frontal lobe epilepsy and the accuracy of predicting lateralization of the F-IHF focus using the predominance of findings.

Cannabis use, sleep and mood disturbances among persons with epilepsy - A clinical and polysomnography study from a Canadian tertiary care epilepsy center.

Objective: Interest in anti-seizure properties of cannabinoids is increasing, with the rise in prevalence of recreational and medical cannabis use, especially across Canada. In a recent study on people with epilepsy (PWE), cannabis use showed a strong association with poor psychosocial health. Sleep and mood comorbidities are highly prevalent in epilepsy, and are common motivations for cannabis use.

EEG features and synek scale indicate severity of neurotoxicity in adult patients treated with CD19 CAR T-cell therapy.

Patients who develop chimeric antigen receptor (CAR) T-cell-related immune effector cell-associated neurotoxicity syndrome (ICANS) frequently undergo evaluation with electroencephalography (EEG). We hypothesize that EEG features and Synek scale score, a measure of degree of EEG abnormality, are associated with ICANS severity. Here, we performed a retrospective review of 125 adult patients at Memorial Sloan Kettering Cancer Center (MSKCC) who received CAR-T cell therapy from 2010 to 2019, including 53 patients with B-acute lymphoblastic leukemia treated with 1928z CAR T cells (NCT01044069) and 72 patients with large B-cell lymphoma (LBCL) treated with the commercial CAR T products axicabtagene ciloleucel or tisagenlecleucel.

Efficacy and tolerability of celastrol and edaravone in the multiple-hit rat model of infantile spasms.

Objective: To test whether anti-inflammatory and antioxidant drugs that inhibit the nuclear factor kappa light chain enhancer of activated B cells (NF-kB), celastrol and edaravone, suppress spasms and improve developmental outcomes in the multiple-hit rat model of refractory infantile spasms (IS) due to structural lesions.

Methods: Postnatal day 3 (PN3) Sprague-Dawley rats were treated according to the multiple-hit IS model protocol. Using a randomized, blinded, vehicle-controlled, dose- and time-response study design, we tested the effects of single celastrol [1, 2, or 4 mg/kg intraperitoneally (i.

Nucleus accumbens shell electrical lesion attenuates seizures and gliosis in chronic temporal lobe epilepsy rats.

Objective: Temporal lobe epilepsy (TLE) is the most prevalent form of epilepsy. Prior research has indicated the involvement of the nucleus accumbens shell (NAcSh) in the process of epileptogenesis, thereby implying its potential as a therapeutic target for TLE. In the present study, we investigated the antiepileptic effect of the NAcSh electrical lesion.

Sensitivity of detecting interictal epileptiform activity using rapid reduced montage EEG.

Objective: Rapid EEG devices (REDs) have demonstrated substantial benefit regarding reduced time to performance of study and diagnosis in cases where urgent EEG is needed to evaluate patients for potentially revealing nonconvulsive status epilepticus and seizures. However, urgent EEG is also important in identifying cases regarding the need for initiation of antiseizure medication as well as triaging the use of continuous EEG monitoring. Some forms of REDs have a reduced montage (RRME) with electrode derivations that are one-half of standard recordings.

Retrospective characterization of seizure semiology and treatment using continuous video-EEG monitoring in neonatal encephalopathy in Uganda.

Objective: Neonatal encephalopathy (NE) is a leading cause of childhood death and disability, particularly in sub-Saharan Africa. Detection of NE-related seizures is challenging. We explored NE seizure semiology and management in Uganda.

Frontal EEG correlation based human emotion identification and classification.

Humans express their feelings and intentions of their actions or communication through emotions. Recent advancements in technology involve machines in human communication in day-to-day life. Thus, understanding of human emotions by machines will be very helpful in assisting the user in a far better way.

Customized GPT model largely increases surgery decision accuracy for pharmaco-resistant epilepsy.

Background: To develop an enhanced epilepsy diagnosis system by integrating an expert-informed ontology with a custom generative pre-trained transformer (GPT), validated by inferring possible seizure lateralization and localization using retrospective textual data from the pre-surgical assessments of patients with pharmaco-resistant epilepsy (PRE).

Methods: We developed an AI system for epilepsy diagnosis using Protégé with OWL/SWRL, integrating a knowledge base with seizure semiology, seizure types EEG descriptors, expert insights, and literature to pinpoint seizure locations. A customized GPT model was then tailored for specific diagnostic needs.

Video-based automatic seizure detection in pharmacoresistant epilepsy: A prospective exploratory study.

Objective: The objective of this study was to evaluate the diagnostic yield and clinical utility of an automated AI video-based seizure detection device, Nelli®, (SDD) in pharmacoresistant epilepsy patients. The SDD captures and automatically classifies nocturnal motor behavior suggestive of epileptic seizures or non-epileptic motor behavior of potential clinical value.

Methods: Patients with focal epilepsy and pharmacoresistance referred for inpatient long-term video-EEG monitoring were prospectively recruited.

Level 4 seizure monitoring unit admissions are associated with reduced long-term health care costs.

Objective: This study was undertaken to determine whether admission to dedicated seizure monitoring units (SMUs) result in reduced health care use (HCU).

Methods: This was a retrospective open cohort study covering the years 2010-2018 of patients residing in Alberta, Canada, who were referred to the Calgary Comprehensive Epilepsy Program and admitted to a level 4 SMU. Patients were required to have ≥3 years pre- and postadmission follow-up.

Peri-ictal yawning: A potential lateralizing sign in temporal lobe epilepsy.

Objective: The primary objective of this retrospective analysis was to evaluate the incidence and lateralization value of peri-ictal yawning (PY) in people with temporal lobe epilepsy (TLE). PY has only occasionally been reported as a manifestation of focal epilepsy. We aimed to determine whether PY could serve as an indicator to help lateralize seizure onset during epileptic seizures.

Introduction: Emotion and attention regulation significantly influence various aspects of human functioning and behavior. However, the interaction between emotion and attention in affecting performance remains underexplored. This study aims to investigate how individual differences in sustained attention, influenced by varying emotional states.

Tonic and tonic-clonic seizures in the first year of life: Insights from electrographic features.

Objective: We studied the electrographic features of tonic seizures (TS) with bilateral contraction and tonic-clonic seizures (TCS) without focal signs occurring during the first year of life to evaluate if there is a correlation with outcome.

Methods: We retrospectively reviewed patients aged 1 to 12 months with at least one TS or TCS recorded with video-EEG between 2011 and 2021 in our Epilepsy Monitoring Unit. We analyzed the following electrographic features: seizure duration, presence and duration of focal ictal EEG onset, and post-ictal generalized EEG suppression (PGES).

Risk factors for wound dehiscence after surgery for epilepsy.

Objective: Wound dehiscence following craniotomy is a complication for which patients are subjected to additional procedures to achieve wound closure. During surgery for epilepsy, a craniotomy is performed at various sites to cure or palliate seizures in patients with intractable epilepsy. Collaborations between medicine and engineering have provided many surgical devices and materials for various stages of craniotomy, from skin incision to wound closure.
