Cornelia de Lange syndrome (CdLS) is a rare disorder associated with developmental delay, intellectual disability, autism features, and behavior regulation difficulties. CdLS has been considered to be a spectrum disorder that ranges from classical to atypical involvement. The severity of CdLS based on physical features has been associated with greater neurological abnormalities and hearing impairment; however, the relationship between CdLS severity and behavioral phenotype has not been examined.

Long COVID affects a significant number of children, yet clinician knowledge gaps and limited access to specialized care hinder effective management. With fewer than 20 pediatric long COVID clinics in the United States, many families must travel long distances for care. To address these challenges, a pediatric long COVID ECHO (Extension for Community Healthcare Outcomes) program was developed to educate health care professionals on evidence-based care.

Processing speed is an important neuropsychological construct, with weaknesses evident across many pediatric medical conditions. During the COVID-19 pandemic, tele-neuropsychological evaluations were widely utilized in children with various health conditions to examine cognitive functioning as part of standard care or disease surveillance. Although remote testing afforded better access to neuropsychological care for many families, psychometric properties of tele-neuropsychological assessments, and particularly the equivalence of processing speed measures across in-person versus telehealth test modality, remain underexamined.

During the COVID-19 pandemic, teleneuropsychology (teleNP) practice was quickly adopted to afford continuity of clinical care, however, the teleNP literature in children remains limited and focused on specific clinical populations and/or select test measures. Notably, attention and executive functioning are commonly assessed in neuropsychological assessments of patients with medical conditions, psychological, or educational concerns, yet few studies have offered support for teleNP administration of measures targeting these cognitive domains in children. This cross-sectional study involved a retrospective chart review of pediatric patients who underwent an in-person neuropsychological evaluation at an academic medical center before the pandemic ( = 287) or videoconference teleNP assessment during the pandemic ( = 277).

Article Synopsis
  • The study examines sleep behaviors in individuals with Cornelia de Lange syndrome (CdLS) caused by variants in two genes, NIPBL and SMC1A, which are linked to developmental delays.
  • Caregivers of 31 individuals provided data showing that those with NIPBL variants exhibited more behavior regulation difficulties and repetitive behaviors compared to those with SMC1A variants.
  • The research highlights a strong connection between sleep disturbances and behavior regulation challenges, particularly in the NIPBL group, suggesting that sleep interventions may help manage behavioral issues differently depending on the genetic variant.

The coronavirus disease-2019 (COVID-19) pandemic, caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), has had a profound global impact on individual health and well-being in adults and children. While most fully recover from COVID-19, a relatively large subgroup continues to experience persistent physical, cognitive, and emotional/behavioral symptoms beyond the initial infection period. The World Health Organization has termed this phenomenon "Post-COVID-19 Condition" (PCC), better known as "Long COVID.

KAT6B and KAT6A belong to the MYST family of lysine acetyltransferases, and regulate gene expression via histone modification. Although both proteins share similar structure and epigenetic regulatory functions, it remains unclear if KAT6A/6B mutation disorders, both very rare conditions, yield the same neurocognitive presentation and thus benefit from similar treatment approaches. This study provides a preliminary overview of neuropsychological functioning of 13 individuals with KAT6B disorder (Mean age = 9.

Background: Cornelia de Lange (CdLS) is a rare genetic disorder that affects most body systems. Variants in multiple genes including NIPBL and SMC1A, can cause the syndrome. To date, literature on genotype-phenotype associations in individuals with CdLS is extremely limited, although studies suggest some differences in clinical phenotype severity across variants.

Children with long COVID often report symptoms that overlap with cognitive disengagement syndrome (CDS, previously sluggish cognitive tempo (SCT)), a set of behaviors distinct from attention-deficit/hyperactivity disorder (ADHD) including excessive daydreaming, mental fogginess, and slowed behavior and thinking. Those with long COVID also frequently report low mood and anxiety, which are linked to CDS. The relationships between cognitive difficulties, mood, and functional impairment have yet to be explored in pediatric long COVID.

Objective: When socioeconomic status is measured at the individual and/or family level, it has long been associated with cognition in children. However, the association between neighborhood deprivation, an index of community-level socioeconomic status, and child cognition is not fully understood. The goal of this study was to investigate (1) the relationship between neighborhood deprivation and child cognitive functioning and (2) whether child age moderates the relationship between cognitive functioning and neighborhood deprivation.

Missed patient appointments have a substantial negative impact on patient care, child health and well-being, and clinic functioning. This study aims to identify health system interface and child/family demographic characteristics as potential predictors of appointment attendance in a pediatric outpatient neuropsychology clinic. Pediatric patients ( = 6,976 across 13,362 scheduled appointments) who attended versus missed scheduled appointments at a large, urban assessment clinic were compared on a broad array of factors extracted from the medical record, and the cumulative impact of significant risk factors was examined.

Epigenetics, one mechanism by which gene expression can change without any changes to the DNA sequence, was described nearly a century ago. However, the importance of epigenetic processes to neurodevelopment and higher order neurological functions like cognition and behavior is only now being realized. A group of disorders known as the Mendelian disorders of the epigenetic machinery are caused by the altered function of epigenetic machinery proteins, which consequently affects downstream expression of many genes.

Many early-career neuroscientists with diverse identities may not have mentors who are more advanced in the neuroscience pipeline and have a congruent identity due to historic biases, laws, and policies impacting access to education. Cross-identity mentoring relationships pose challenges and power imbalances that impact the retention of diverse early career neuroscientists, but also hold the potential for a mutually enriching and collaborative relationship that fosters the mentee's success. Additionally, the barriers faced by diverse mentees and their mentorship needs may evolve with career progression and require developmental considerations.
