Delayed modulation of alpha band activity increases response inhibition deficits in adolescents with AD(H)D.

Deficiencies in inhibitory control are one of the hallmarks of attention-deficit-(hyperactivity) disorder (AD(H)D). Response inhibition demands can become increased through additional conflicts, namely when already integrated representations of perception-action associations have to be updated. Yet, the neural mechanisms of how such conflicts worsen response inhibition in AD(H)D are unknown, but, if identified, could help to better understand the complex nature of AD(H)D-associated impulsivity. We investigated both behavioral performance and EEG activity in the theta and alpha band of adolescents (10-18 years of age) with AD(H)D (n = 28) compared to neurotypical (NT) controls (n = 33) in a conflict-modulated Go/Nogo paradigm. We used multivariate pattern analysis (MVPA) and EEG-beamforming to examine how changes in representational content are coded by oscillatory activity and to delineate the cortical structures involved in it. The presented behavioral and neurophysiological data show that adolescents with AD(H)D are more strongly affected by increased response inhibition demands through additional conflicts than NT controls. Precisely, AD(H)D participants showed higher false alarm rates than NT controls in both, non-overlapping and overlapping Nogo trials, but performed even worse in the latter. This is likely due to an inefficient updating of representations related to delayed modulations of alpha band activity in the ventral stream and orbitofrontal regions. Theta band activity is also modulated by conflict but was not differentially affected in the two groups. By this, the present study provides novel insights into underlying neurophysiological mechanisms of the complex nature of response inhibition deficits in adolescents with AD(H)D, stressing the importance to examine the interplay of theta and alpha band activity more closely to better understand inhibitory control deficits in AD(H)D.

Clinico-Demographic Profile of Children and Adolescents with Attention Deficit Hyperactivity Disorder Presenting to a Tertiary Care Centre: A Descriptive Cross-sectional Study.

INTRODUCTION: Attention deficit hyperactivity disorder (ADHD) is a common neurodevelopmental disorder in children. ADHD leads to significant impairment in overall functioning of the child. There is limited information concerning the clinical scenario of ADHD within Nepal. The study aims to determine the clinico-demographic profile and pattern of medication use in the treatment of ADHD. METHODS: This study retrospectively examines the records of children diagnosed with ADHD at the Child and Adolescent Psychiatry (CAP) Unit, Kanti Children's Hospital (KCH), Nepal. Approval for the study was granted by KCH's Institutional Review Board. The analysis focused on data extracted from hospital records of ADHD patients spanning from 1 January 2021 to 30 June 2023 encompassing two and a half years. RESULTS: A total of 585 children were diagnosed with ADHD, with a mean age 7±3.04 years. The majority 501 (85.64%) were male, and 377 (64.44%) were from the school going age group (6 to 11 years). The prevalent psychiatric comorbidities included Autism Spectrum Disorder (ASD) at 102 (17.43%), Intellectual Disability (ID) at 93(15.89%), and Oppositional Defiant Disorder (ODD) at 36 (6.15%). The commonly used medication was Clonidine 165 (28.20%) followed by Atomoxetine 154 (26.32%) and Risperidone 65 (11.11%). CONCLUSIONS: The study indicates that ADHD is highly prevalent in Nepal. Comorbidities like ASD and ID are frequently seen which further necessitates the need for structured assessments and multidisciplinary approaches to address ADHD. In our context with limited treatment options, the management of ADHD is extremely challenging.

Sleep Problems in Adults With ADHD: Prevalences and Their Relationship With Psychiatric Comorbidity.

BACKGROUND: Sleep problems are common in adults with ADHD and may be bidirectionally associated with ADHD severity and other psychiatric symptoms. We investigated the prevalence of positive screenings for various sleep disorders, and their association with psychiatric comorbidities in a large sample of adults with ADHD from a specialized outpatient clinic. METHODS: We included data of 3,691 adult patients diagnosed with ADHD, who had filled out a screener for sleep disorders (Holland Sleep Disorders Questionnaire (HSDQ)) as part of routine diagnostic assessment. The HSDQ screens for the sleep disorders insomnia, parasomnia, hypersomnia, circadian rhythm sleep disorders (CRSD), restless legs syndrome (RLS)/periodic limb movement disorder (PLMD), and sleep-related breathing disorders (SBD). As delayed sleep phase syndrome (DSPS) is very frequent in ADHD, we additionally screened for DSPS. Psychiatric comorbidities were diagnosed through clinical assessment and the Mini International Neuropsychiatric Interview (M.I.N.I.) Plus, which assesses 26 psychiatric disorders following the classification of the DSM-5. All data were retrieved from the electronic patient files. RESULTS: Mean age was 35.4 and 49.4% of the patients were female. About 60% of the adults with ADHD screened positive for any sleep disorder. Highest prevalences were found for symptoms of DSPS (36%), insomnia (30%), and RLS/PLMD (29%). Sleep problems in adults with ADHD were associated with comorbid depression, anxiety, substance use disorder, personality disorder, and post-traumatic stress disorder. CONCLUSION: Adults with ADHD often report sleep problems, which are associated with specific psychiatric comorbidities. Systematic screening for sleep disorders in adult patients with ADHD can contribute to a better understanding of their complaints and may aid improved and integrated treatment for the sleep and psychiatric problems.

Neurodiversity in the Minds of Students: From Perception to Campus Programming.

Neurodiversity is a social justice movement at the nexus of neuroscience, academia, and public policy. A contemporary view of neurodiversity is one that embraces neurological differences, encompassing all "neurotypes," including more specific identifiers like autistic or dyslexic. The goal of this study was to investigate student awareness and perception of neurodiversity since they are the next generation of public policy makers. Students enrolled in Introduction to Behavioral Neuroscience (N=146) were exposed to different information sources (popular, academic, TED talk, or choose/find their own) on the topic of neurodiversity. They then wrote a paper where they summarized: a) the information source used, b) their ideas to better support a neurodiverse society, and c) their opinions on aspects of neurodiversity. Several important findings emerged. First, 64% of the sample had never heard of the term neurodiversity; this class was their first exposure to it. Second, students conducting their own searches on neurodiversity had the highest level of optimism (p < 0.05) that society was ready to accept neurodiversity. Students identified even higher rates of receptivity (85%) amongst their friends. Third, student ideas to advance neurodiversity were organized into more salient categories for campuses to consider. Our findings challenge neuroscience programs to consider their role in providing "first exposure" opportunities to students in the diversity, equity, and inclusion realm, especially in areas directly related to our field. We also discuss the growing relevance of neurodiversity in research and academia and offer programming possibilities to enhance neurodiversity awareness and support on college campuses.

Subtle motor signs in children with ADHD and their white matter correlates.

Subtle motor signs are a common feature in children with attention-deficit/hyperactivity disorder (ADHD). It has long been suggested that white matter abnormalities may be involved in their presentation, though no study has directly probed this question. The aim of this study was to investigate the relationship between white matter organization and the severity of subtle motor signs in children with and without ADHD. Participants were 92 children with ADHD aged between 8 and 12 years, and 185 typically developing controls. Subtle motor signs were examined using the Physical and Neurological Examination for Soft Signs (PANESS). Children completed diffusion MRI, and fixel-based analysis was performed after preprocessing. Tracts of interest were delineated using TractSeg including the corpus callosum (CC), the bilateral corticospinal tracts (CST), superior longitudinal fasciculus, and fronto-pontine tracts (FPT). Fiber cross-section (FC) was calculated for each tract. Across all participants, lower FC in the CST was associated with higher PANESS Total score (greater motor deficits). Within the PANESS, similar effects were observed for Timed Left and Right maneuvers of the hands and feet, with lower FC of the CST, CC, and FPT associated with poorer performance. No significant group differences were observed in FC in white matter regions associated with PANESS performance. Our data are consistent with theoretical accounts implicating white matter organization in the expression of motor signs in childhood. However, rather than contributing uniquely to the increased severity of soft motor signs in those with ADHD, white matter appears to contribute to these symptoms in childhood in general.

Lisdexamfetamine's Efficacy in Treating Attention Deficit Hyperactivity Disorder (ADHD): A Meta-Analysis and Review.

Lisdexamfetamine dimesylate, a prodrug stimulant, appears to effectively treat Attention-Deficit/Hyperactivity Disorder (ADHD) in children and adults. However, an analysis of the treatment effects of the two subscales (inattentiveness and hyperactivity) within the ADHD Rating Scale-IV (ADHD-RS-IV) has not yet been done to determine if clinical significance may be attributed to either one. Nor has there been a meta-analysis of the individual doses of lisdexamfetamine dimesylate. The current meta-analysis utilizes MEDLINE, Embase, Cochrane, PubMed, and clinicaltrials.gov to identify peer-reviewed studies. Selected studies were eligible if they met the following criteria: English language, randomized-controlled trials, and utilized the ADHD-RS-IV scale to assess the efficacy of lisdexamfetamine on treating ADHD in either children or adults. The primary studies utilized were published between January 2007 and April 2024. Many of these studies calculate effect sizes based on several dosages pooled together rather than by individual dosages. We conducted a random-effects meta-analysis to estimate the effect sizes for these pooled dosages on the full ADHD-RS-IV scale and its subscales, as well as to calculate effect sizes on the same scales based on the individual dosages. Our main outcome measures are the ADHD-RS-IV scale and its subscales in individual doses and pooled results in both children and adults. Adverse events during treatment were also analyzed based on stratified dosages. Eleven publications met our inclusion criteria. The analyses indicate that compared to placebo, lisdexamfetamine effectively alleviates the symptoms outlined by the ADHD-RS-IV. Moreover, there are no differences in the individual subscales or in the safety profile. Lisdexamfetamine demonstrates efficacy in treating the symptoms of ADHD, but we report that differing dosages did not yield significant differences in ADHD symptom management.

Evaluation of Frontal QRS-T Angle in Children With ADHD and Healthy Controls.

INTRODUCTION: Conflicting findings exist regarding the link between attention deficit hyperactivity disorder (ADHD) and cardiovascular diseases. This study aimed to evaluate the frontal QRS-T (fQRS-T) angle and its correlation with symptom severity in children diagnosed with ADHD. METHODS: The study population consisted of 172 patients diagnosed with ADHD (120 drug naive and 52 drug positive) and 82 healthy controls. ADHD symptoms were assessed using the Atilla Turgay DSM-IV-Based Screening and Assessment Scale for Disruptive Conduct Disorders (T-DSM-IV-Scale). The fQRS-T angle and corrected QT (QTc) interval were obtained from the automated reports of 12-lead electrocardiography device for each patient. RESULTS: QTc interval and fQRS-T angle were significantly different among the groups. Post hoc analyses showed that QTc interval and fQRS-T angle of ADHD drug naive and ADHD drug positive patients were significantly higher than the healthy control groups. However, there was no significant difference between drug naive and drug positive patients regarding QTc interval and fQRS-T angle. Both QTc interval and fQRS-T angle showed positive correlations with the severity of ADHD symptoms (r = 0.263, p = .001 and r = 0.175, p = .023 respectively). CONCLUSION: We found that fQRS-T angle was significantly wider in children with ADHD. Therefore, we suggest that fQRS-T angle may help in cardiovascular risk assessment in children with ADHD.

Eye-tracking training improves visuospatial working memory of children with attention-deficit/hyperactivity disorder and autism spectrum disorder.

Given the close connection between eye movement and frontal lobe functions and some evidence supporting the effect of eye-tracking training on enhancing cognitive performance mediated by the frontal lobe, this study aimed to explore if after-school eye-tracking training can improve the visuospatial working memory (VSWM) and cognitive flexibility performance in children with attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD). This study is a non-randomized cluster trial. Forty children from eight primary schools were selected, half receiving eye-tracking training for 20 sessions over 9 months, while the other half served as a waitlist control. They were matched on demographic characteristics and baseline cognitive performance. Their VSWM and cognitive flexibility were assessed at the beginning and end of the study. Results showed that children who received eye-tracking training, but not those on a waitlist, exhibited significant improvements in the total score and working memory span of the VSWM tests, and the correct responses in cognitive flexibility tests. Specifically, VSWM performance at higher span levels (5 or above) yielded a greater improvement. The findings suggest that eye-tracking training can be a feasible and effective after-school program for improving working memory and cognitive flexibility performance in children with ADHD and ASD. This study was prospectively registered at ClinicalTrials.gov (https://clinicaltrials.gov/, trial number: NCT05428657).

Multi-informant evaluation of Cognitive Disengagement Syndrome (formerly Slow Cognitive Tempo). Children's self-reported measures in relation to parents / Evaluación multi-informante del Síndrome de Desconexión Cognitiva (anteriormente Tempo Cognitivo Lento). Medidas autoinformadas de los niños con relación a padres

El objetivo fue examinar, desde una aproximación multi-informante, las medidas del Síndrome de Desconexión Cognitiva (SDC) de padres/madres e hijos/as y su relación con síntomas internalizantes y externalizantes. 279 niños/as (9-13 años), y sus padres/madres completaron las evaluaciones sobre SDC, la inatención del trastorno por déficit de atención e hiperactividad (TDAH) y otras medidas internalizadas y externalizadas. Los ítems de las tres medidas de SDC convergieron razonablemente bien en el factor SDC. Se aportaron pruebas discriminantes de la validez de las relaciones entre las puntuaciones de las pruebas y las medidas de los tres constructos diferentes (SDC, soledad y preferencia por la soledad). La asociación más estrecha estuvo entre la evaluación parental de las medidas de SDC con ansiedad y depresión, y entre inatención con hiperactividad/impulsividad y trastorno negativista desafiante. Se observó capacidad predictiva de la medida de SDC sobre la soledad y preferencia por estar solo autoinformadas. Se encontró una posible asociación entre la medida del SDC evaluado por padres/madres y sexo y edad de los niños. En conclusión, los datos apoyan la inclusión de medidas autoinformadas en la evaluación del SDC. Las medidas del SDC en niños se vinculan con medidas internalizantes y, la inatención con las externalizantes.(AU)

Effectiveness of a game-based high-intensity interval training on executive function and other health indicators of children with ADHD: A three-arm partially-blinded randomized controlled trial.

Background: Children with ADHD demand for effective intervention with minimum side effect to improve executive function (EF) and health well-being. Method: This study used a three-arm partially-blinded randomized controlled trial to test the effects of two different kinds of 8-week game-based training programs (game-based HIIT program, GameHIIT; and game-based structured aerobic exercise program, GameSAE) on EF and other health indicators of children with ADHD, which was compared with a non-treatment control group. Results: A total of 49 children with ADHD completed the program. Analyses of EF tests and parental survey indicated that (i) there is no significant intragroup difference among all measures between pre-/post-intervention tests for two game-based intervention groups. The only significant intergroup difference was observed in self-monitor score of parent-reported child's EF between GameSAE group and the control (large effect). Similarly, cerebral hemodynamic responses also found no significant group effect for all EF tests. However, the time effects were observed in several channels in the GameHIIT group in two EF tests (Color Words Stroop Test and Tower of London Test). No significant change of participants' overall ADHD symptoms was found in the pre-/post-tests for three groups. Nonetheless, further analyses revealed that both of two game-based training programs exhibited the significant positive effects on child's PA levels and the large effects on levels of physical fitness, when they were compared to the control. Conclusion: By this study, a significant enhancement in physical fitness and PA levels were found in both game-based PA interventions when they were compared with control group. However, the effectiveness of game-based PA interventions on improving EF or reducing ADHD symptoms remains unclear. This implies that a larger intervention dosage or a tailored intervention design may be warranted to improve the EF of children with ADHD.

Therapeutic Decisions and Implications in Patients With Attention Deficit Hyperactivity Disorder Versus Bipolar Disorder: Key Insights for Clinicians.

Attention deficit hyperactivity disorder (ADHD) and pediatric bipolar disorder (BD) are conditions that often manifest in childhood and can persist into adulthood. Due to the similarities in their clinical presentations, it is crucial for clinicians to have a thorough understanding of these disorders. Accurate differentiation of symptoms is essential for making precise diagnoses, as this directly influences treatment decisions and affects the overall functioning and quality of life of those impacted. Considered here is the case of a teenage male who initially presented with impulsivity and was diagnosed with ADHD. However, upon further evaluation, his diagnosis was revised to BD. This case highlights the importance of diagnostic accuracy in clinical practice. Correctly identifying these conditions ensures timely and appropriate treatment, which can significantly alter the life trajectory of affected individuals. This encompasses improvements in health outcomes and better functioning in social, occupational, and other aspects of their lives when treatment is appropriately tailored.

Economic Evaluation of a Novel Treatment of Attention-Deficit/Hyperactivity Disorder in US Motor Vehicle Drivers.

Background: Attention-deficit/hyperactivity disorder (ADHD) affects approximately 4.4% of US adults. ADHD is associated with high-risk driving behavior and costly motor vehicle accidents. DYANAVEL XR (DXR) (Tris Pharma, Inc.) is a once-daily fast-acting amphetamine developed for ADHD treatment. A randomized controlled trial showed that DXR patients were 43% less likely to crash during a driving simulation than individuals taking placebo. Study outcomes suggest a DXR crash rate similar to that of a driver without ADHD, while patients treated with the current standard of care (SOC) have a 52% higher crash risk than non-ADHD drivers. Objective: The aim was to evaluate the economic benefits attributable to improved driving abilities and avoided crashes in DXR patients compared with patients treated with the SOC or those who are untreated. Methods: A cost-impact model estimated 1-year crash-related cost outcomes for DXR-treated patients compared with SOC-treated and untreated ADHD patients. SOC was assumed to consist of a combination of short-, intermediate-, and long-acting ADHD stimulant and non-stimulant medications. DXR crash risk was assumed equivalent to the non-ADHD population risk, as supported by trial data. Crash risk for untreated and SOC-treated ADHD patients were assumed to be 99% and 52% higher than the general US population, respectively. Model outcomes included the cost impact (medication- and crash-related costs) and the number of crashes, injuries, and fatalities avoided with DXR. Results: Treatment with DXR would avoid 0.82 crashes, 0.016 injuries, and 0.036 fatalities per year compared with untreated patients, and 0.036 crashes, 0.007 injuries, and 0.0001 fatalities per year compared with SOC-treated patients. Compared with a population of 25% SOC-treated patients and 75% untreated patients, DXR use would save an average of 4581 p e r p e r s o n p e r y e a r a c r o s s a l l a g e g r o u p s w h e n p r i c e d a t 80 per month, assuming all SOC-treated and untreated patients utilized DXR. When the value of quality-of-life improvement is considered, savings increase over 7-fold. Discussion: Outcomes suggest that DXR may be an economically beneficial treatment compared with SOC for ADHD patients. Conclusions: The economic model showed that DXR is cost-saving compared with no treatment and SOC by reducing the number of motor vehicle crashes in the ADHD population.

Having Reliable Support: A Prerequisite to Promote Sexual and Reproductive Health in Young Women with ADHD.

Living with attention deficit hyperactivity disorder (ADHD) may influence sexual behaviors and intimate relationships in young women, resulting in a higher risk of unwanted pregnancy, sexual victimization, and sexual dysfunction. To develop adequate support, the study aimed to describe conceptions of how to promote sexual and reproductive health (SRH) in young women with ADHD. A secondary analysis using phenomenography was performed on qualitative interview data exploring variations of support. The study involved 15 young women with ADHD, aged 15-29 years, and 16 health care professionals, with various professions, working in the fields of gynecology, youth health, and psychiatry. Having reliable support was conceptualized as fundamental for promoting SRH. Access to information concerning SRH and living with ADHD as well as early support from health care contributed to a reliable support enabling self-knowledge and management of sexual relationships. Trustful relationships in health care were perceived as important because of previous experiences of feeling misunderstood and criticized in life, making them feel comfortable discussing SRH. Clinical encounters with a clear structure were further perceived to make information more accessible and clinics that provided appropriate organizational conditions and collaborated with other clinics were described to enhance the availability of support. This study reveals the need for clinics to provide conditions that ensure SRH support is available, accessible, and free of stigmatization. Early intervention programs for young women with ADHD may be considered, offering guidance on SRH issues in both psychiatric and sexual health clinics.

Feasibility of the Understanding and Managing Adult ADHD Programme: open-access online group psychoeducation and acceptance and commitment therapy for adults with attention-deficit hyperactivity disorder.

BACKGROUND: Psychoeducational interventions are a critical aspect of supporting adults with attention-deficit hyperactivity disorder (ADHD). The Understanding and Managing Adult ADHD Programme (UMAAP) is a six-session, group-based webinar intervention that incorporates psychoeducation with acceptance and commitment therapy. UMAAP relies on self-referrals and is facilitated by a charity, to promote accessibility. AIMS: The present study aimed to evaluate the feasibility of UMAAP and explore preliminary effectiveness. METHOD: Adults with formally diagnosed or self-identified ADHD (n = 257) participated in an uncontrolled pre-post design. Feasibility was indicated by attendance, confidence in completing the home practice and satisfaction. Quality of life, psychological flexibility, self-acceptance and knowledge of ADHD were assessed at baseline, 1 week post-intervention and 3 months later, to explore preliminary effectiveness. RESULTS: Feasibility was demonstrated by the high attendance ratings and satisfaction with the intervention, although there was only moderate confidence in the ability to complete the home practices. Quality of life (mean increase 9.69, 95% CI 7.57-11.80), self-acceptance (mean increase 0.19, 95% CI 0.10-0.28) and knowledge of ADHD (mean increase 1.55, 95% CI 1.23-1.82) were significantly improved post-intervention. The effects were maintained at the 3-month follow-up. Psychological flexibility did not significantly change immediately post-intervention, but increased significantly at the 3-month follow-up (mean increase 0.42, 95% CI 0.26-0.58). CONCLUSIONS: Overall, UMAAP is a feasible intervention for adults with ADHD. Findings highlighted the feasibility of delivering psychological interventions online in group settings, to increase access to support for adults with ADHD.

A novel self-rating instrument designed for long-term, app-based monitoring of ADHD symptoms: A mixed-methods development and validation study.

Background: Regular outcome monitoring is essential for effective attention deficit hyperactivity disorder (ADHD) treatment, yet routine care often limits long-term contacts to annual visits. Smartphone apps can complement current practice by offering low-threshold, long-term sustainable monitoring capabilities. However, special considerations apply for such measurement which should be anchored in stakeholder preferences. Methods: This mixed-methods study engaged 13 experienced clinicians from Region Stockholm in iterative qualitative interviews to inform development of an instrument for app-based ADHD monitoring: the mHealth scale for Continuous ADHD Symptom Self-monitoring (mCASS). A subsequent survey, including the mCASS and addressing app-based monitoring preferences, was administered to 397 individuals with self-reported ADHD. Psychometric properties of the mCASS were explored through exploratory factor analysis and examinations of internal consistency. Concurrent validity was calculated between the mCASS and the Adult ADHD Self-Report Scale-V1.1 (ASRS-V1.1). Additional quantitative analyses included summary statistics and repeated-measures ANOVAs. Results: Clinicians identified properties influencing willingness to use and adherence including content validity, clinical relevance, respondent burden, tone, wording and preferences for in-app results presentation. The final 12-item mCASS version demonstrated four factors covering everyday tasks, productivity, rest and recovery and interactions with others, explaining 47.4% of variance. Preliminary psychometric assessment indicated satisfactory concurrent validity (r = .595) and internal consistency (α = .826). Conclusions: The mCASS, informed by clinician and patient experiences, appears to be valid for app-based assessment of ADHD symptoms. Furthermore, insights are presented regarding important considerations when developing mobile health (mHealth) instruments for ADHD individuals. These can be of value for future, similar endeavours.

Clinical Profile of Neurodevelopmental Disorders in Children at a Tertiary Care Center.

Background Neurodevelopmental disorders (NDDs) encompass intricate interactions among genetic, brain, cognitive, emotional, and behavioral processes. These disorders, which are influenced by hereditary and environmental factors, impair personal, social, intellectual, or occupational functioning. Typically emerging early in life, NDDs include conditions such as attention deficit hyperactivity disorder (ADHD), intellectual disability, autism spectrum disorders (ASDs), vision and hearing impairments, motor disorders, and specific learning disabilities. Children from impoverished and low-income neighborhoods are particularly vulnerable. The lack of comprehensive health data and public awareness about these conditions results in limited information regarding the prevalence of neurological illnesses in developing countries. India, with its large and ethnically diverse population, exemplifies this gap. Methods It is a prospective study to detect the prevalence and risk factors of neurodevelopmental disorders in children aged six months to nine years at a tertiary care center. Patient details, clinical findings, and relevant history were recorded on a pre-designed pro forma and analyzed statistically. Results Among the 1000 children in the study, 91 (9.1%) tested positive for NDDs. Among the 91 children who tested positive for NDD, the highest frequency is in the three to four years age group (17.6%), males were found to be in a higher ratio with 75.82%, with the male: female ratio being 3:1. Among the 91 children with NDD, intellectual disability was the most common disorder (20.9%), followed by ADHD (17.6%) and vision impairment (14.3%). Autism spectrum disorders, including autism and Asperger syndrome, and communication disorders, including stuttering and speech disorders, accounted for 13.2% each. Hearing loss was seen in 9.9% of children and multiple disorders were seen in 8.8% of the children from among 91 children. Conclusion Neurodevelopmental disorders are common and often coexist with other conditions. Children from low-income backgrounds are more affected. This study provides valuable insights into the prevalence and characteristics of NDDs in a specific population.

Dynamic interactions of physiological systems during competitive gaming: insights from network physiology - case report.

This study investigates the dynamic interactions between physiological systems during competitive gaming, utilizing a Network Physiology approach. By examining the physiological responses of a gamer with attention-deficit/hyperactivity disorder playing a real-time strategy game, we explore the relationships and temporal lag effects between pupil dilation, skin temperature, and heart rate. Our findings highlight the interconnectedness of these physiological systems and demonstrate how different physiological states are associated with unique patterns of network interactions. The study employs the concept of Time Delay Stability towards a deeper understanding of the complex dynamics involved. This research contributes to the growing field of Network Physiology by offering new insights into the physiological underpinnings of competitive gaming, potentially informing targeted training and recovery protocols for eSports athletes.

Attention-deficit hyperactivity disorder is associated with risky and unhealthy behaviours among adolescents.

OBJECTIVES: Attention-deficit hyperactivity disorder (ADHD) is highly prevalent among adolescents globally, particularly in Israel. This study aimed to evaluate associations between ADHD and engagement in risky/unhealthy behaviours among adolescents. STUDY DESIGN: Cross-sectional study. METHODS: Students participating in the 2015-2016 National Health Survey completed self-administered questionnaires, providing demographic, medical and behavioural information (n = 4616, 11-18 years old, 50.2% male). Multivariable logistic regression analyses assessed the associations between ADHD and risky/unhealthy behaviours, including current tobacco/hookah smoking, alcohol consumption (≥1 serving/month), excessive screen time (≥4 h/d), non-compliance with physical activity and sleep recommendations (<1 h/d, and <8 or <9 h/d depending on age, respectively) and unhealthy lifestyle (engagement in ≥3 of these behaviours). RESULTS: A total of 752 participants reported ever being diagnosed with ADHD (287 of whom were treated with stimulants) and 3864 individuals were included in a non-ADHD comparison group. ADHD was significantly associated with higher prevalence of smoking (odds ratio [OR] 2.15; 95% confidence interval [CI]: 1.65, 2.80), alcohol consumption (OR 1.38; 95% CI: 1.10, 1.73) and excessive screen time [OR 1.41; 95% CI: 1.18, 1.70), each adjusted for sociodemographic characteristics and the other risky/unhealthy behaviours. Unhealthy lifestyle was twice as common in the ADHD group (OR 2.03; 95% CI: 1.64, 2.51). Stimulant-treated and non-treated adolescents with ADHD did not differ in demographic or behavioural characteristics. CONCLUSIONS: ADHD was significantly associated with an unhealthy lifestyle among adolescents. These behaviours should be detected early and prevention measures put in place to limit their harmful consequences in this adolescent population. Additional large-scale prospective research is needed to deepen the understanding of this association.

Low utility of serum folic acid blood tests in healthy children and adolescents, a nationwide cohort.

This study aimed to evaluate the utility of serum folic acid testing in children and adolescents in a developed country without mandatory folic acid food fortification and to identify patients at risk for folic acid deficiency. In this cross-sectional study, records from primary care and hospitals were reviewed for patients aged 0-18 years who underwent serum folic acid testing. Data were retrieved from the Leumit-Health-Services database over a ten-year period (January 2008 to December 2018). Clinical and laboratory data were compared between patients with folic acid deficiency to those with normal levels. Among 20,411 pediatric patients tested, 884 (4.3%) had folic acid deficiency, of whom only 26.3% had anemia. Only two patients (0.2%) had megaloblastic anemia. Multivariate analysis showed that male gender (odds ratio(OR)1.6, 95% CI 1.22-2.12), older age (OR 1.32, 95% CI 1.26-1.39), higher BMI percentile (OR 1.01, 95% CI 1-1.01), antipsychotic treatment (OR 3.23, 95% CI 1.52-6.84), celiac (OR 2.97, 95% CI 1.66-5.34), and Attention-Deficit-and-Hyperactivity-Disease (ADHD) treated with psychostimulants (OR 2.21, 95% CI 1.56-3.12) were associated with folic acid deficiency(all p < 0.01). Lower hemoglobin levels were independently associated with increased OR of folic acid deficiency (OR 0.77, 95% CI 0.66-0.90, p = 0.001), but anemia as a diagnosis was not. CONCLUSION: Pediatric folic acid deficiency rates were low in this nationwide cohort and not linked to megaloblastic anemia, likely due to concomitant iron deficiency anemia. Although retrospective, this might suggest low utility for routine serum folic acid testing in healthy children in developed countries, except in cases of celiac disease or specific medication use such psychostimulants or antipsychotics. WHAT IS KNOWN: • Folic acid deficiency is common among children in developing countries, causing megaloblastic anemia, growth delays, and cognitive impairments. In developed countries, the prevalence is considered low. WHAT IS NEW: • Of 20,411 pediatric patients tested for serum folate, in a developed country, only 4.3% had folate deficiency. • Risk factors for deficiency included celiac, antipsychotics, and psychostimulant treatment for ADHD. • Routine folate testing in developed countries may have limited utility; Targeted screening is recommended.
