Neonatal isoflurane exposure in rodents disrupts hippocampal cognitive functions, including learning and memory, and astrocytes may have an important role in this process. However, the molecular mechanisms underlying this disruption are not fully understood. The present study investigated the role of TWIK‑related K+ channel (TREK‑1) in isoflurane‑induced cognitive impairment. Lentiviruses were used to overexpress or knockdown TREK‑1 in astrocytes exposed to increasing concentrations of isoflurane or O2 for 2 h...

Recently the role of soil-transmitted helminth (STH) infections in children's cognitive developmental impairment has been under scrutiny. We conducted a systematic review of the evidence for associations between STH infections and cognitive function of children using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses protocol. We aimed to identify the domains of cognitive function in three age strata (<24months, 24-59months and ≥60months) and critically appraise the general design protocol of the studies, with a focus on the cognitive function measurement tools used...

Children born very preterm (VP; <32 weeks' gestational age) are at risk for unfavorable outcomes in several cognitive domains, including spatial working memory (WM). The underlying neural basis of these cognitive impairments is poorly understood. We investigated differences in neuronal activation during spatial WM using a backward span (BS) task relative to a control (C) task in 45 VP children and 19 term-born controls aged 13 years. VP children showed significantly more activation in the bilateral superior frontal gyrus and significantly less activation in the left parahippocampal gyrus compared with controls...

OBJECTIVE: Applying frontal transcortical approach to treat lateral ventricular tumor is one of the most common neurosurgical manipulations. The frontal transcortical approach generally passes through the middle frontal gyrus in which there is no major function involved in the traditional sense. However, current researches have suggested that the prefrontal cortex (PFC) plays a central role in the whole network of the brain cognitive frame. In addition, cognitive function is crucial in growing and developmental stages and essential for the educational achievement, especially for children...

Sylvette R Wiener-Vacher, Sidney I Wiener
The video head impulse test (VHIT) is widely used to identify semicircular canal function impairments in adults. But classical VHIT testing systems attach goggles tightly to the head, which is not tolerated by infants. Remote video detection of head and eye movements resolves this issue and, here, we report VHIT protocols and normative values for children. Vestibulo-ocular reflex (VOR) gain was measured for all canals of 303 healthy subjects, including 274 children (aged 2.6 months-15 years) and 26 adults (aged 16-67)...

REVIEW
Peter Fonagy, Patrick Luyten
Problems related to aggression in young people are traditionally subsumed under the header of conduct problems, which include conduct disorder and oppositional defiant disorder. Such problems in children and adolescents are an important societal and mental health problem. In this paper we present an evolutionarily informed developmental psychopathology view of conduct problems inspired by the NIMH Research Domain Criteria (RDoC) initiative. We assume that while there are many pathways to conduct problems, chronic or temporary impairments in the domain of social cognition or mentalizing are a common denominator...

OBJECTIVES: Congenital hemiplegia is the most common form of cerebral palsy (CP). Children with unilateral CP show signs of upper limb asymmetry by 8 months corrected age (ca) but are frequently not referred to therapy until after 12 months ca. This study compares the efficacy of infant-friendly modified constraint-induced movement therapy (Baby mCIMT) to infant friendly bimanual therapy (Baby BIM) on upper limb, cognitive and neuroplasticity outcomes in a multisite randomised comparison trial...

Stunting is associated with impaired cognitive and motor function. The effect of an education intervention including nutrition, stimulation, sanitation, and hygiene on child growth and cognitive/language/motor development, delivered to impoverished mothers in Uganda, was assessed. In a community-based, open cluster-randomized trial, 511 mother/children dyads aged 6-8 months were enrolled to an intervention (n = 263) or control (n = 248) group. The primary outcome was change in length-for-age z-score at age 20-24 months...

Synopsis Accurate, reliable, and timely assessment of pain is critical for effective management of musculoskeletal pain conditions. The assessment of pain in infants, children, and adolescents with and without cognitive impairment can be particularly challenging for clinicians for a number of reasons, including factors related to: the consultation (eg, heterogeneous patient population, time constraints), the clinician (eg, awareness / knowledge of available pain scales), standardised assessment scales (eg, availability, psychometric properties, and application of each scale) the patient (eg, developmental stage, ability to communicate), and the context in which the interaction takes place (eg, familiarity with the setting and physiological and psychological state)...

Archival data were used to examine the feasibility of a 5-day, clinic-based, intensive exposure-based cognitive-behavioral group therapy for childhood anxiety disorders (CADs) and obsessive-compulsive disorder (OCD). Participants were 143 children (82 girls) aged 6 to 19 years ( M = 13.93 years, SD = 2.9 years) with CADs or OCD (or both) in 28 consecutive groups. Repeated-measures ANOVA in the subsample ( n = 57) with complete treatment data indicated positive change on all variables from pretreatment to posttreatment with few differences between CADs and OCD patients...

A growing body of literature suggests that ADHD is associated with emotion recognition impairments that may be linked to deficient interpersonal functioning. However, our understanding of the mechanisms underlying these recognition impairments is extremely limited. Here, we used dynamic stimuli to investigate whether impaired emotion recognition in children with ADHD may be associated with impairments in perceptual sensitivity. Participants (ADHD: N = 26; Controls: N = 26) viewed video sequences of neutral faces slowly developing into one of the six basic emotional expressions (angry, happy, fearful, sad, disgusted and surprised) and were instructed to indicate via a button press the precise moment at which they were able to correctly recognize the emotional expression...

PURPOSE: To validate the Cognitive Problems in Children and Adolescents Questionnaire (KOPKIJ, German: Kognitive Probleme bei Kindern und Jugendlichen), a proxy report measure for recognizing cognitive problems in pediatric patients with epilepsy. METHODS: Anonymized data sets from 279 pediatric epilepsy patients were standardized in regard to the KOPKIJ results of 352 healthy children and adolescents. The KOPKIJ was related to objective routine neuropsychological assessment (NPY), and to two subjective measures, the Child Behavior Checklist questionnaire (CBCL), a proxy rating by the parents, and a questionnaire for self-perceived health-related quality of life in children and adolescents (KINDL)...

An age-matched achievement-matched design was used to examine whether the executive functioning and working memory impairments exhibited by children with severe difficulties in arithmetic (SDA) are better viewed as developmental lags or as cognitive deficits. Three groups of children were included: 20 SDA children, 20 typically achieving children (CM) matched in chronological age with the SDA children, and 20 younger typically achieving children (AM) matched in achievement with the SDA group. While children with SDA did not exhibit impairments in color-word inhibition and verbal working memory, they did demonstrate impairments in shifting, quantity-digits inhibition, and visuospatial working memory...

BACKGROUND Liver transplantation (LT) is recommended for various metabolic diseases, including urea cycle disorders (UCDs). The aim of this study was to determine indications and outcomes of LT for UCDs in the tertiary reference Children's Hospital in Warsaw, Poland. MATERIAL AND METHODS Medical charts of children with UCD who underwent LT between 2008 and July 2016 were retrospectively reviewed. The following parameters were analyzed: symptoms at time of diagnosis, age at diagnosis, age at transplantation, graft characteristics and survival, postsurgical complications, and biochemical and laboratory results before and after transplantation...

Excessive ethanol (EtOH) intake, especially to prenatal exposure, can significantly affect cognitive function and cause permanent learning and memory injures in children. As a result, how to protect children from EtOH neurotoxicity has gained increasing attention in recent years. Piracetam (Pir) is a nootropic drug derived from c-aminobutyric acid and can manage cognition impairments in multiple neurological disorders. Studies have shown that Pir can exert therapeutic effects on EtOH-induced memory impairments, but the underlying mechanism is still unknown...

BACKGROUND: Recent studies in children have reported associations of urinary cadmium (U-Cd), used as biomarker of Cd body burden, with renal dysfunction, retarded growth and impaired cognitive development in children. Little is known, however, about factors influencing U-Cd in children and likely to act as confounders. METHODS: In a cross-sectional study involving 249 schoolchildren (mean age, 5.72 years; 138 boys), we measured the urine concentrations of cadmium, zinc, lead, albumin, alpha1-microglobulin (A1M), retinol-binding protein, β2-microglobulin and club cell protein (CC16)...

BACKGROUND: Uncontrolled seizures in children can contribute to irreversible cognitive impairment and developmental delay, in addition to placing them at risk for sudden unexplained death in epileptic patients (SUDEP). Since its introduction at Saint Ann Hospital in Paris in the 1960s, stereoelectroencephalography (SEEG) is increasingly being utilized at epilepsy centers in the United States as an invasive tool to help localize the seizure focus in drug-resistant focal epilepsy. INDICATIONS: Children with symptomatic epilepsy, commonly due to cortical dysplasia and dysembryoplastic neuroepithelial tumor (DNET), may benefit from SEEG investigation...
