Radiomics neurobiomarkers for distinguishing mathematical-related areas in children with elevated ADHD symptoms
(2025) Pina, Violeta; Campello, Víctor M.; Booth, James R.; Fenollar Cortés, Javier
Children with ADHD symptoms are at higher risk of experiencing mathematical difficulties. Individuals with ADHD often exhibit lower mathematical accuracy and rely on more basic strategies, even without comorbid learning disorders. In this study, we aim to identify whether this higher risk is associated with general (e.g. executive function) or specific (e.g. calculation) mathematical abilities by analyzing brain areas in structural imaging with radiomics. We used a public brain imaging dataset of mathematical development in children to define two subgroups: one with ADHD symptoms and a control group, matched for age mean and variance. Then, we explore the differences in brain regions related to mathematical performance between these groups using radiomics features in structural imaging. Our results confirm a lower mathematical performance in the group with ADHD symptoms in the behavioral analysis. Structurally, we found differences between the groups in key brain regions associated with attention and memory, including the inferior and middle frontal cortex bilaterally, the right posterior cingulate cortex, and the left hippocampus. Features related to shape demonstrated the highest predictive power. We hypothesize that children with ADHD symptoms might have difficulties with 'number attention' and propose future studies in this area.
Sociocultural attitudes towards appearance and attitudes towards eating in adolescents with type 1 diabetes. The importance of perfectionism
(2025) Ruiz Aranda, Desireé; Luque, Ana; Russo, Francesca; Fenollar Cortés, Javier
Adolescents managing type 1 diabetes (T1D) are at increased risk of experiencing eating disorders (EDs). Identifying risk factors is essential to develop preventive strategies. This study examines the potential mediation value of self-esteem and the perfectionism associated with EDs in the relationship between sociocultural attitudes toward appearance and eating attitudes related to EDs in a sample of adolescents with T1D.
A high degree of perfectionism could be a risk variable when developing potential eating problems in T1D adolescents. Perfectionism and its self-management would be a prominent factor that may help to design interventions developed for adolescents with diabetes who show behaviors that potentially conflict with eating. The clinical implications are discussed.
