Memory Performance on the ChAMP in Autism Spectrum Disorder With and Without Attention-Deficit/Hyperactivity Disorder

This study examined memory performance on the Child and Adolescent Memory Profile (ChAMP) in 146 youth with ASD (92 with co-occurring ADHD, 54 without), finding that ChAMP performance did not predict ADHD co-occurrence and showed no additive memory effects. The study sample performed better than the ChAMP manual's ASD reference sample on all measures, suggesting potential population differences in memory profiles across ASD groups.

Reduced Gaze-Cueing Effect with Neutral and Emotional Faces in Adults with ADHD

This study compared gaze-cueing effects in 45 adults with ADHD and 45 matched controls using a visual attention task with emotional and neutral face cues. Both groups showed faster target detection when gaze pointed toward targets, but the effect was smaller in ADHD participants, suggesting less reflexive attention orienting to others' gaze cues.

Attention-Deficit Hyperactivity Disorder Among American Youth: A Comprehensive 20-Year Analysis of National Center for Health Statistics Data

This 20-year retrospective analysis of NCHS data (1997-2018) examined ADHD prevalence among American youth, finding boys had higher rates (12.93% vs 5.61%) with peak prevalence in the 10-17 age group (11.09%). The study identified significant demographic and socioeconomic disparities, including variations by race/ethnicity and income level.

Prenatal and Childhood Exposure to Chlorpyrifos and Pyrethroid Insecticides and ADHD Symptoms in Preschool Children

This cohort study examined associations between insecticide exposure (measured via urine metabolites in pregnant women and 5-year-old children) and ADHD symptoms assessed using validated behavioral screening. Most pregnant women and children had detectable levels of pyrethroid and chlorpyrifos metabolites, with statistical analysis exploring dose-response relationships by child sex.

Suicidality and Nonsuicidal Self-Injury in Females with ADHD: A Narrative Review

This narrative review examines the relationship between ADHD and increased suicide risk in females, highlighting how impulsivity as a core ADHD symptom contributes to suicidal behavior and self-harm. The review identifies combined-type ADHD, comorbid depression, substance abuse, and childhood maltreatment as key risk factors, emphasizing the need for active suicide prevention in this population.

Attitudes of South Australian psychiatrists towards adult ADHD: barriers to service access

A survey of 73 South Australian psychiatrists identified major barriers to treating adult ADHD, including fear of case overload (68.5%), lack of clinical experience (32.9%), and concerns about drug-seeking behavior (31.5%). The study concludes that increased training and wider psychiatric involvement are needed to improve service accessibility and distribute ADHD treatment workload more equitably.

Cardiovascular risk in adults with Delayed Sleep Phase Syndrome and ADHD

This registered clinical trial investigates the relationship between delayed sleep phase syndrome, ADHD, and cardiovascular risk in adult populations. The study appears to examine physiological health outcomes associated with these neurodevelopmental and sleep conditions.

Monobloc Appliance Treatment for Sleep-Disordered Breathing and Associated ADHD Symptoms in School-Aged Children

This retrospective study examined whether treating sleep-disordered breathing with a monobloc oral appliance improves ADHD symptoms in children ages 5–12 using parent questionnaires from 40 children across three dental offices. While 61% showed some symptom improvement at 7+ months, the study lacked a control group, formal ADHD diagnosis confirmation, and used only parent-reported measures, limiting causal conclusions about the intervention's effectiveness for ADHD.

Voluntary Imitation of Dynamic Facial Expressions in Children with ADHD: A Facial-Behavior Analysis Study

This study compared voluntary facial mimicry of emotional expressions between 41 children with ADHD and 53 typically developing children using video recording and computer vision analysis. Children with ADHD demonstrated significantly higher imitation intensity for sadness, surprise, and fear expressions, though emotion recognition accuracy was equivalent between groups.

Are congenital heart defects connected to more severe attention-deficit/hyperactivity disorder?: A systematic review and meta-analysis

This meta-analysis of 8 observational studies involving 120,158 patients found that congenital heart defects are statistically significantly associated with increased ADHD severity scores, particularly on the ADHD index and hyperactivity-impulsivity subscales. The findings suggest a potential link between cardiac conditions and ADHD symptom severity, though causality is not established.

Concussion Risk and Recovery in Athletes With ADHD on Psychostimulant Treatment

This NCAA-DOD CARE Consortium study found that athletes with ADHD diagnosis face higher concussion risk and longer symptom recovery, but those treated with psychostimulants show recovery patterns similar to non-ADHD athletes and reduced symptom severity. The findings suggest psychostimulant medications may provide a protective effect on concussion recovery outcomes in ADHD populations.

An adolescent boy with kleptomania and ADHD treated with methylphenidate and guanfacine: A case report

A 16-year-old boy with both ADHD and kleptomania (impulse to steal unneeded items) was treated with methylphenidate (OROS formulation), which improved both ADHD symptoms and stealing behavior. Adding guanfacine in the evening addressed residual symptoms during times when methylphenidate levels dropped, suggesting potential efficacy of this combination in managing both conditions.

Influence of psychostimulants on bone mineral density and content in children with ADHD: A systematic review

This systematic review examined whether psychostimulant medications affect bone mineral density and content in children with ADHD by analyzing five clinical studies with durations of five to seven years. The findings were mixed, with some studies showing reduced bone mineral content and density in patients taking psychostimulants, while others reported changes in bone turnover and metabolic markers.

Neuropsychological Factors and Loneliness Preference in Children with ADHD and Cognitive Disengagement Syndrome

This study examined how emotion dysregulation and internalizing disorders mediate the relationship between attention difficulties and preference for solitude in 176 children (ages 8-12) with ADHD and Cognitive Disengagement Syndrome. Findings suggest that selective and sustained attention deficits predict loneliness preference primarily through difficulties in emotion regulation and co-occurring internalizing problems.

Handwriting Deficits in Children with ADHD: A Systematic Review of Product and Process Features

This systematic review examines whether children with ADHD show handwriting abnormalities at both the product level (legibility, speed) and process level (pen pressure, velocity, timing). Analysis of 21 studies found that methodologically rigorous studies consistently reported impaired handwriting in ADHD children, though considerable methodological variation exists across the research literature.

A longitudinal examination of executive function abilities, attention-deficit/hyperactivity disorder, and puberty in adolescence

This 3-year longitudinal study tracked 99 adolescents (ages 8-19) to examine how age, puberty levels, and ADHD symptoms relate to executive function development. Results showed that older adolescents with advanced pubertal development had lower executive function, and that earlier executive function deficits predicted later ADHD burden but not vice versa.

Gut-Microbiome Alterations in Adult ADHD: A Meta-Analysis of Harmonized Sequencing Studies

This meta-analysis harmonized bioinformatic analyses of 16S rRNA sequencing data from four adult ADHD case-control studies (N=617) to identify consistent microbial alterations. Specific bacterial genera including Ruminococcus_torques_group and Eubacterium_xylanophilum_group showed robust associations with ADHD diagnosis and related symptom profiles, though beta diversity results showed significant heterogeneity across cohorts.
