Atypical absence seizures and gene variants: A gene-based review of etiology, electro-clinical features, and associated epilepsy syndrome
Epilepsy Behav. 2024 Feb;151:109636. doi: 10.1016/j.yebeh.2024.109636. Epub 2024 Jan 16.ABSTRACTAtypical absence seizures are generalized non-convulsive seizures that often occur in children with cognitive impairment. They are common in refractory epilepsy and have been recognized as one of the hallmarks of developmental epileptic encephalopathies. Notably, pathogenic variants associated with AAS, such as GABRG2, GABRG3, SLC6A1, CACNB4, SCN8A, and SYNGAP1, are also linked to developmental epileptic encephalopathies. Atypical absences differ from typical absences in that they are frequently drug-resistant and the prognosis ...

Transition in epilepsy - A pilot study with patients in and outside of academic centers
CONCLUSIONS: This study highlights the lack of appropriate transition to adult healthcare system (AHCS) amongst an unselected group of patients with epilepsy in Canada and United States. An overwhelming majority of patients followed in the community and in academy centers were simply "transferred" to an adult health practitioner, or they remained under the care of pediatricians. Finally, most patients lack access to significant social and medical support after moving to the AHCS.PMID:38219605 | DOI:10.1016/j.yebeh.2024.109624 (Source: Epilepsy and Behaviour)

Effects of valproic acid and levetiracetam monotherapy on balance functions in patients with generalized epilepsy
CONCLUSION: Valproic acid and levetiracetam may affect the vestibulocular and vestibulocolic reflex pathways negatively. In this cohort, valproic acid had more pronounced adverse effects on balance functions as compared to levetiracetam.PMID:38219606 | DOI:10.1016/j.yebeh.2024.109622 (Source: Epilepsy and Behaviour)

Health care access, psychosocial outcomes and mental health in adults living with epilepsy during the COVID-19 pandemic
CONCLUSION: Our cohort of PLWE experienced some challenges during the COVID-19 pandemic including poorer mental health and financial and employment-related stressors. Encouragingly, healthcare access was relatively spared during the COVID-19 crisis, with some patients even reporting a reduction in seizure burden. However, PLWE require ongoing psychosocial support with particular attention to decompensation of mental health and social stressors that may be exacerbated by the COVID-19 pandemic.PMID:38219607 | DOI:10.1016/j.yebeh.2023.109617 (Source: Epilepsy and Behaviour)

The longitudinal effects of cannabidiol on brain temperature in patients with treatment-resistant epilepsy
Epilepsy Behav. 2024 Feb;151:109606. doi: 10.1016/j.yebeh.2023.109606. Epub 2024 Jan 9.ABSTRACTNeuroinflammation (NI) is a key pathophysiological contributor to treatment-resistant epilepsy (TRE) that remains challenging to observe in vivo. Magnetic resonance spectroscopic imaging and thermometry (MRSI-t) is an emerging technique that can be used to non-invasively map brain temperature, whereby brain temperature elevations serve as a surrogate for the cellular and biochemical processes associated with NI. In a previous multimodal imaging study of focal epilepsy patients, we observed MRSI-t-based brain temperature elevation...

How to handle a missed or delayed dose of lacosamide in pediatric patients with epilepsy? a mode-informed individual dosing
This study aims to investigate the effects on the pharmacokinetic (PK) of lacosamide (LCM), and to guide the individual dosing regimens for children and ones with poor medication adherence. Population PK research was performed based on 164 plasma samples of 113 pediatric patients aged from 1.75 to 14.42 years old. The PK characteristic of LCM was developed by a one-compartment model with first-order elimination. The typical value of apparent clearance (CL) and apparent volume of distribution (Vd) was 1.91 L·h-1 and 56.53 L respectively. In the final model, the variability of CL was significantly associated with the body s...

Cross-cultural validation and psychometric properties of the Spanish version of the quality of life in Childhood epilepsy Questionnaire (QOLCE-55)
CONCLUSIONS: The Spanish version of the QOLCE-55 has demonstrated adequate psychometric properties, indicating that it can be confidently used to measure the health-related quality-of-life (HRQoL) in children with epilepsy in a Spanish-speaking population. These results corroborate the instrument's cross-cultural validity.PMID:38194772 | DOI:10.1016/j.yebeh.2023.109619 (Source: Epilepsy and Behaviour)

Transient anticonvulsant effects of time-restricted feeding in the 6-Hz mouse model
CONCLUSIONS: Both continuous and 2:5 TRF regimens transiently increased seizure thresholds in the 6-Hz model at around 2 weeks, which coincided with stability of blood glucose levels during the fed and fasted periods. Our findings suggest that the lack of prolonged anticonvulsant effects in the acute electrical seizure models employed may be attributed to only modest metabolic and antioxidant adaptations found in the brain and liver. Our findings underscore the potential therapeutic value of TRF in managing seizure-related conditions.PMID:38184948 | DOI:10.1016/j.yebeh.2023.109618 (Source: Epilepsy and Behaviour)

Cognitive and psychiatric adverse events during adjunctive cenobamate treatment in phase 2 and phase 3 clinical studies
CONCLUSIONS: Cognitive and psychiatric TEAEs were reported by similar numbers of cenobamate- and placebo-treated patients during double-blind adjunctive cenobamate treatment (< 4 % of patients), and exposure-adjusted incidence rates of these TEAEs remained low during open-label cenobamate treatment for up to 7 years. Treatment discontinuations due to these TEAEs were rare. The results of this post-hoc analysis indicate that adjunctive cenobamate treatment exhibits a low incidence of cognitive or psychiatric TEAEs in patients with uncontrolled focal seizures.PMID:38184949 | DOI:10.1016/j.yebeh.2023.109605 (Source: Epilepsy and Behaviour)
