Article Synopsis
- The study compared concussion histories between children with ADHD and those without, using data from the ABCD Study with a sample of 10,585 kids aged 9-10.
- Children with ADHD had a 7.2% history of concussion, while only 3.2% of those without ADHD had similar histories, indicating that ADHD is linked to a higher likelihood of prior concussions.
- There were no significant differences in concussion rates between boys and girls with ADHD, and the number of ADHD symptoms didn't correlate with concussion history.

Article Abstract
This case-control study using baseline data from the population cohort Adolescent Brain Cognitive Development (ABCD) Study compared lifetime history of concussion between children with and without attention-deficit/hyperactivity disorder (ADHD). We hypothesized that children with ADHD would have a greater lifetime history of concussion than children without ADHD. Children were recruited from schools across the United States, sampled to provide strong generalizability to the US population. The current sample included 10,585 children (age: mean = 9.9; standard deviation = 0.6; range 9-10 years; 48.9% girls; 64.6% White), including 1085 with ADHD and 9500 without ADHD. The prevalence of prior concussion among children with ADHD was 7.2% (95% CI: 6.6-7.8%) compared with 3.2% (3.1-3.3%) among children without ADHD, meaning current ADHD status was associated with twice the odds of experiencing a prior concussion [ = 44.54; < 0.001; odds ratio = 2.34 (1.81-3.03)]. No significant differences were observed in proportion of boys and girls with ADHD who had a prior concussion history. The number of current ADHD symptoms were not meaningfully associated with prior concussion history. Lower socioeconomic status was associated with lower rates of reported concussion, but not differentially in association with ADHD. ADHD is associated with twice the lifetime prevalence of prior concussion before age 11 among children from the general U.S. population. Boys and girls with ADHD did not differ in proportions with prior concussion and concussion history was not related to the number of ADHD symptoms reported by parents.

Background: Recent epidemiological evidence links early-life obesity and metabolic dysregulation to adult psychosis vulnerability, though a causal relationship remains unclear. Establishing causality in highly heritable psychotic disorders requires: 1) demonstrating that early-life metabolic factors mediate between genetic vulnerability and psychosis trajectory, 2) dissecting mechanisms leading to early-life obesity in genetically vulnerable individuals, and 3) clarifying downstream neurodevelopmental pathways linking early-life obesity to psychosis symptoms.
Methods: Here we investigated bidirectional pathways linking behavioral, BMI, and neurodevelopment trajectories in a unique longitudinal cohort of 184 individuals at high genetic risk for psychosis, due to 22q11.

Methylphenidate (MPH) is the first-line treatment for Attention-Deficit/Hyperactivity Disorder (ADHD), a condition that disrupts daily functioning. Research indicates that individuals with ADHD often experience sensory processing impairments, regardless of co-occurring conditions. Given the growing interest in pharmacogenetics to personalise treatments and minimise side effects, this study aims to characterise the sensory profiles of in child and youth ADHD patients treated with MPH and investigate potential pharmacogenetic biomarkers that could be associated with treatment outcomes or sensory-related side effects.

Background: Sleep disturbances are highly prevalent in children with neurodevelopmental disorders (NDD), yet few studies have combined objective and subjective measures. The objectives of this study were to evaluate sleep patterns and sleep hygiene in children with ADHD and ASD compared age-matched typically developing children, using both parent-reported questionnaires and actigraphy, to assess the concordance between these measures, and to determine the clinical applicability of actigraphy in this population.
Methods: Sixty children with NDD (30 ASD, 30 ADHD) and 40 typically developing controls, matched for age, underwent seven nights of actigraphic recording.

Background: Hypertensive disorders of pregnancy may be associated with an increased risk of adverse neurodevelopmental outcomes for the child, though no recent comprehensive meta-analyses exist. The aim of this study was to conduct a systematic review and meta-analysis examining the association between hypertensive disorders of pregnancy and child neurodevelopmental disabilities, intelligence, and educational outcomes.
Methods And Findings: A search was conducted of MEDLINE, CINAHL, Web of Science, and PsycINFO databases from inception until 18 September 2024.

Developmental Dyslexia (DD) and Attention-deficit/hyperactivity disorder (ADHD) are neurodevelopmental disorders that often coexist and share complex genetic underpinnings. Our case study integrates psychological assessments and whole exome sequencing to explore the genetic basis of DD and ADHD co-occurrence in a single proband (a nine-year-old female born to healthy) from a consanguineous Pakistani family. We present a proband with symptoms of impulsivity, inattention, and severe hyperactive behavior, along with speech impairment and moderate learning disabilities.
