To determine whether multiple subpial transection in the posterior temporal lobe has an impact on long-term outcome children who have drug-resistant Landau-Kleffner syndrome (LKS) or other "electrical status epilepticus during sleep" (ESES)-related regression. Given wide variability outcomes reported literature, a secondary aim was to explore predictors of outcome.The current study includes surgery group (n = 14) comprising patients underwent and nonsurgery comparison 21) presurgical...

There is an increasing need to identify and treat sleep disturbances in Tourette syndrome (TS), a neurodevelopmental condition characterized by tics. This study explored sleep, tics, executive functioning children with TS (n=136) neurotypical controls (n=101) through parent-report scales open-ended questions. 85% of scored the clinical range for disorder. Higher tic severity predicted increased difficulties. Qualitative insights indicated bidirectional link between which warrants...

In addition to pain, sickle cell anaemia (HbSS) complications include neurocognitive difficulties in attention and processing speed associated with low daytime night-time oxygen saturation compounded by obstructive sleep apnoea (OSA). the general population OSA is treated continuous positive airways pressure (CPAP). The aim of this single-blind, randomised, controlled phase II trial compare auto-adjusting CPAP (APAP) standard care alone individuals HbSS determine whether intervention...

Abstract Snoring and poor sleep may affect cognition, particularly in young children with chronic conditions. Parents of London preschoolers sickle cell anemia (SCA; n = 22), matched controls (n 24), unselected typically developing 142) completed questionnaires. Preschoolers SCA had significantly more problems when compared to the larger population. occurred at least one two nights a week for 79% group. This is 25% 33% Randomized controlled trials improve already at‐risk cognitive...

Abstract. Previous analyses of response time distributions have shown that the Stroop effect is observed in mode (μ) and standard deviation (σ) normal part distribution, as well its tail (τ). Specifically, interference related to semantic processes has been suggested specifically affect tail, respectively. However, only one study literature directly manipulated interference, none manipulating interference. The present research aims address this gap by both a manual task, examining how these...

Children with sickle cell anemia (SCA) are commonly reported to experience executive dysfunction. However, the development of function (EF) in preschool-age children without stroke this patient population has not been investigated so it is unclear when and how these deficits emerge.This case-control study examines feasibility assessing early functioning 22 preschool years SCA domains processing speed, working memory, attention, inhibitory control, cognitive flexibility, as well everyday...

Executive deficits are commonly reported in children with sickle cell anemia. Earlier identification of executive would give more scope for intervention, but this cognitive domain has not been routinely investigated due to a lack age-appropriate tasks normed preschool children. In particular, information relating patient performance on an task that reflects everyday activity the classroom could provide important insight and practical recommendations teacher at key developmental juncture as...

There is increasing recognition of the high prevalence sleep issues in children with Tourette syndrome (TS), a condition characterised by motor and vocal tics. Overnight polysomnography (PSG) has been primary mode assessment TS literature, despite extensive use actigraphy other neurodevelopmental populations. As result, there are existing research gaps surrounding day-to-day variability links to daytime functioning. This study adopts naturalistic, intensive longitudinal design examine while...

Executive functioning (EF) skills are crucial for young students to meet academic and social demands at school. EF skill development is particularly amenable environmental influences in the early years. In classroom settings, teachers play a vital role providing support promote these skills.

Sensory modulation difficulties are commonly reported in patients with ADHD, however there has been little focus on the development of these young children at a higher risk later ADHD diagnosis. This study investigated whether familial history show greater sensory difficulties. We also explored was linked to negative affectivity, which highlighted as potential early marker ADHD. Parents under 6 years family (n = 65) and no 122) completed questionnaires temperament. Children from families...
