Simple Summary: Individuals with neurofibromatosis type 1 (NF1) are vulnerable to socioemotional difficulties. However, we know little about how socioemotional functioning changes across childhood and adolescence and what factors predict the change. The current longitudinal study aims to address this gap by examining how demographic and NF1-disease related factors predict development of socioemotional functioning in a sample of children and adolescents with NF1 and PNs. We found substantial within-group variabilities in socioemotional development with developmental patterns varying across socioemotional domains, reporters of socioemotional functioning, age at baseline, parental education, race/ethnicity, number of NF1-related complications, and visibility of tumors. These findings indicate the need for individualized patient care and interventions that consider each child's unique background and needs. The results also suggest the need for more longitudinal research to further understand how various factors affect socioemotional development in children with NF1 to better inform intervention development and practices. Individuals with neurofibromatosis type 1 (NF1) and plexiform neurofibromas (PNs) have a higher risk for socioemotional problems. The current study aims to identify the socioemotional developmental pattern and its predictors across childhood and adolescence in individuals with NF1 and PNs. Participants included 88 children with NF1 and PNs (aged 6–18 years old, M = 12.05, SD = 3.62, 57% male) in a natural history study. Neuropsychological assessments were administered three times over six years. There are large variabilities in socioemotional development in the study participants. Developmental patterns varied across socioemotional domains, respondent type (parent-report [PR] vs. child-report [CR]), demographic factors, and NF1 disease-related factors. For instance, lower parental education was associated with a greater decline in internalizing problems (PR) but a greater increase in school disconnectedness (CR) over time. Non-White (vs. White) children were more likely to experience increased adaptive skills (PR) but decreased personal adjustment (CR). Children with more visible tumors experienced a greater decrease in school disconnectedness (CR). Children with more NF1 complications experienced a greater decrease in externalizing problems (PR). These findings indicate the necessity of using multi-informants and investigating subdomains of socioemotional functions. They also highlight the importance of developing individualized approaches to patient care and interventions. [ABSTRACT FROM AUTHOR]

Aim: To describe the cognitive development of children with neurofibromatosis type 1 (NF1) and plexiform neurofibromas, and identify predictors of cognitive development.Method: Participants included 88 children with NF1 and plexiform neurofibromas (50 males, 38 females, aged 6-18y, mean=12y, SD=3y 7mo) on a natural history study at the National Cancer Institute. Neuropsychological assessments (e.g. IQ, academic achievement, attention, and executive functioning) were administered three times over 6 years.Results: Relative to normative peers, the total sample of children with NF1 and plexiform neurofibromas demonstrated significantly lower scores in most cognitive domains and decreasing z-scores over time in math, writing, inhibitory control, and working memory. Children who had parents with (vs without) NF1 were more likely to experience decreased z-scores in performance IQ, reading, writing, attention, and working memory. Higher (vs lower) parental education was related to higher levels of IQ, math, reading, and cognitive flexibility and a slower decrease in math z-scores. Children's sex and the number of NF1 disease-related complications were not related to most cognitive outcomes.Interpretation: Children with NF1 and plexiform neurofibromas are at high risk for cognitive difficulties and declining z-scores in various domains of cognitive functioning over time. The findings highlight the need for a better understanding of the within-group differences in these children and their need for individualized educational plans.What This Paper Adds: Math, writing, inhibitory control, and working memory scores decreased over time. The proportion of children with clinically significant cognitive deficits increased over time. Parental neurofibromatosis type 1 and low education were related to greater cognitive difficulties in children. [ABSTRACT FROM AUTHOR]

The article reflects the changes in the publication schemes of the journal due to the relocation of its office to the Newcastle Upon Thyne, England. Among the changes include the new editorial team which is to develop and sustain the high quality and international reputation of the journal through publishing high standard theoretical research in an international, multi and interdisciplinary field of regional studies. Special and mini-theme issues are introduces as an integral part of the publishing.
