Background And Objective: Information on self-limited epilepsy with centrotemporal spikes (SeLECTS) epidemiology is limited. We aimed to determine the incidence of SeLECTS in children, its association with socioeconomic deprivation and the prevalence of neurodevelopmental comorbidities.

Method: We performed a retrospective cohort study (2004-2017) using anonymised, linked, routinely collected, primary care and demographic data for children in Wales.

Objective: People with epilepsy (PWE) may be at an increased risk of severe COVID-19. It is important to characterize this risk to inform PWE and for future health and care planning. We assessed whether PWE were at higher risk of being hospitalized with, or dying from, COVID-19.

Objective: This study was undertaken to characterize changes in health care utilization and mortality for people with epilepsy (PWE) during the COVID-19 pandemic.

Methods: We performed a retrospective study using linked, individual-level, population-scale anonymized health data from the Secure Anonymised Information Linkage databank. We identified PWE living in Wales during the study "pandemic period" (January 1, 2020-June 30, 2021) and during a "prepandemic" period (January 1, 2016-December 31, 2019).

Study Objectives: Epilepsy and obstructive sleep apnea syndrome (OSAS) are each relatively common in children. OSAS may affect cognition, such that recognition of OSAS is important for children and young people with epilepsy (CYPWE). Published pilot data reported 55% of CYPWE had symptoms suggestive of OSAS, compared with 7% of typically developing controls.

Objective: To examine whether epilepsy-related deaths increased during the COVID-19 pandemic and if the proportion with COVID-19 listed as the underlying cause is different between people experiencing epilepsy-related deaths and those experiencing deaths unrelated to epilepsy.

Methods: This was a Scotland-wide, population-based, cross-sectional study of routinely-collected mortality data pertaining to March-August of 2020 (COVID-19 pandemic peak) compared to the corresponding periods in 2015-2019. ICD-10-coded causes of death of deceased people of any age were obtained from a national mortality registry of death certificates in order to identify those experiencing epilepsy-related deaths (coded G40-41), deaths with COVID-19 listed as a cause (coded U07.

Objective: To estimate Mortality Rate (MR) in UK children with epilepsy (CWE) compared to children without epilepsy (CWOE), describe causes of death, determine Mortality Rate Ratios (MRRs) for cause-specific mortality, and to analyse the contribution of co-morbidities (respiratory disease, neoplasm, and congenital disorders) to mortality rate.

Method: Retrospective cohort study of children born between 1998 and 2017, using linked data from the Clinical Practice Research Datalink Gold (Set 18). Epilepsy diagnoses were identified using previously validated codes.

Objective: Mental distress is present in a significant proportion of people with epilepsy (PWE), with a negative impact across life domains. It is underdiagnosed and under-treated despite guidelines recommending screening for its presence (e.g.

Background: Attention Deficit Hyperactivity Disorder (ADHD) can co-occur in up to 40% of people with epilepsy. There is debate about the efficacy and tolerability of stimulant and non-stimulant drugs used to treat people with ADHD and co-occurring epilepsy.

Objectives: To assess the effect of stimulant and non-stimulant drugs on children and adults with ADHD and co-occurring epilepsy in terms of seizure frequency and drug withdrawal rates (primary objectives), as well as seizure severity, ADHD symptoms, cognitive state, general behaviour, quality of life, and adverse effects profile (secondary objectives).

CDKL5 Deficiency Disorder (CDD) is a rare, X-linked dominant condition that causes a developmental and epileptic encephalopathy (DEE). The incidence is between ~ 1:40,000 and 1:60,000 live births. Pathogenic variants in lead to seizures from infancy and severe neurodevelopmental delay.

Dravet syndrome (DS), Lennox-Gastaut syndrome (LGS) and CDKL5 deficiency disorder (CDD) are rare epileptic conditions, characterised by drug-resistant seizures. Seizure management in these patients requires careful therapy selection. This targeted literature review (TLR) aimed to collate and synthesise information from country-specific and international treatment guidelines for DS, LGS and CDD.

Article Synopsis
  • * The study involved 284 children diagnosed with CD, with a mean age of 8.3 years, and noted a higher occurrence of neurological problems in males and those diagnosed at an older age.
  • * Interestingly, the prevalence of these neurological problems in the studied children was lower compared to what adult CD studies reported, and it is similar to or lower than the prevalence in the general childhood population.

Objective: Lennox-Gastaut syndrome (LGS) is an epileptic encephalopathy that is often treatment resistant. Efficacy and safety of add-on cannabidiol (CBD) to treat seizures associated with LGS was demonstrated in two randomized controlled trials (RCTs). Patients who completed the RCTs were invited to enroll in this long-term open-label extension (OLE) trial, GWPCARE5 (NCT02224573).

Rationale: Children and young people with epilepsy (CYPwE) are particularly vulnerable to developing social, emotional, behavioral, and learning difficulties, which, if not identified or addressed at an early stage, can impact adversely on quality of life and long-term psychosocial outcomes. This paper describes the development of a screening protocol and a pathway of early, 'stepped' intervention, which aims to address this issue, together with initial outcomes.

Methods: The Strengths and Difficulties Questionnaire (SDQ) was completed by CYPwE and their parents prior to routine epilepsy clinic appointments.

Background: The prognosis of convulsive status epilepticus (CSE), a common childhood medical neurological emergency, is not well characterised. We aimed to investigate the long-term outcomes in a cohort of participants who previously had CSE.

Methods: In this prospective study, we followed up a population-based childhood CSE cohort from north London, UK (the north London convulsive status epilepticus surveillance study cohort; NLSTEPSS).

Children with cancer are potentially at a high risk of plasma 25-hydroxyvitamin D (25(OH)D) inadequacy, and despite UK vitamin D supplementation guidelines their implementation remains inconsistent. Thus, we aimed to investigate 25(OH)D concentration and factors contributing to 25(OH)D inadequacy in paediatric cancer patients. A prospective cohort study of Scottish children aged 75 nmol/l).

Methods: Children (5-15 years) with active epilepsy were screened using the parent-report (n=69) and self-report (n=48) versions of the Spence Children's Anxiety Scale (SCAS) and the self-report version of the Children's Depression Inventory (CDI) (n=48) in a population-based sample.

Results: A total of 32.2% of children (self-report) and 15.

Objective: To provide data on the health, social care, and education costs of active childhood epilepsy and factors associated with these costs over an 18-month period in a population-based sample.

Methods: The Children with Epilepsy in Sussex Schools (CHESS) study is a population-based study involving school-aged children (5-15 years) with active epilepsy (taking one or more antiepileptic drug and/or had a seizure in the last year) in a defined geographical area in England. Clinical data were collected on 85 children (74% of eligible population) who underwent comprehensive psychological assessment.

Introduction: There is a lack of population-based data on specific cognitive profiles in childhood epilepsy. This study sought to determine the frequency of impairments in global cognition and aspects of working memory and processing speed in a population-based sample of children with "active" epilepsy (on antiepileptic Drugs (AEDs), and/or had a seizure in the last year). Factors significantly associated with global and specific difficulties in cognition were also identified.
