Teaching a foreign language through ICT to students with dyslexia and attention deficit hyperactivity disorder (ADHD) and the role of ICTs

Students with learning disabilities are a heterogeneous group and exhibit particularities in the areas of perception, language, memory, attention and concentration, metacognition, self-regulation, motivation, behavior, social skills and emotional development. It is therefore important to identify these difficulties as early as possible, so that students can be helped in time by adapting teaching to their own needs. New technologies, already promising in a variety of fields, seem to be able to be used for the necessary differentiation of teaching, materials and assessment of students with learning difficulties such as dyslexia and ADHD.

Associations Between DCD Traits, Perceived Difficulties Related to ADHD, ASD, and Reading and Writing Support Needs Among Students in Higher Education: A Pilot Study

Background/Objectives: Since the Act for Eliminating Discrimination against Persons with Disabilities was enacted in 2016, the number of students with disabilities in higher education institutions has increased significantly, creating a greater need for support. Developmental Coordination Disorder (DCD) often coexists with other neurodevelopmental disorders such as Autism Spectrum Disorder (ASD), Attention Deficit Hyperactivity Disorder (ADHD), and reading and writing difficulties; yet, awareness of DCD remains low. This study aimed to investigate the prevalence of DCD traits among Japanese higher education students and their relationship with ADHD, ASD, and reading and writing support needs Methods: A pilot study was conducted with 77 university students (mean age: 19.17 ± 0.68) in the Kansai region, using the Adolescents and Adults Coordination Questionnaire (AAC-Q) to screen for DCD traits, along with a questionnaire assessing difficulties related to ADHD and ASD, and a survey on reading and writing support needs. Results: The study found that 12.9% of students scored more than 1 standard deviation above the mean on the AAC-Q. Students in the DCD trait group (n = 10) reported greater difficulties related to ADHD and ASD than those in the non-DCD group (n = 67). Correlation analysis revealed a moderate-to-strong association between AAC-Q scores and difficulties related to ADHD and ASD among students in the DCD trait group. Conclusions: This study suggests the need to raise awareness about DCD traits and to provide comprehensive support for students with ADHD and ASD in Japanese higher education institutions.

Parenting a child with attention deficit hyperactivity disorder: Jordanian's perspectives.

Raising your child with attention deficit hyperactivity disorder (ADHD) in Jordan is a challenge due to the prevailing behavioral concerns, low availability of specialized care, and generalized feelings of social stigma. This phenomenological study involved twelve Jordanian parents of children aged 4-14years, all diagnosed with ADHD according to DSM-IV-TR criteria. Participants were recruited through purposive sampling, and semi-structured interviews were conducted. Thematic analysis revealed three key themes: "The Journey through ADHD," in which parents recognized the abnormalities of their children, reported suffering during the diagnosis, and described a wide range of uncertainty regarding the diagnosis and treatments. The second theme was "Disease as part of life," where parents reported the impact on family dynamics and social life. The third theme was "Caregiving burden," reflecting physical and emotional exhaustion and financial burden. Jordanian parents caring for children with ADHD face several challenges, including physical, emotional, economic, and social challenges and limited access to specialized services. Identifying their unique needs and challenges is essential in supporting them, providing appropriate services and resources, and developing policies and guidelines for culturally competent quality services.

Mediating pathways between attention deficit hyperactivity disorder and type 2 diabetes mellitus: evidence from a two-step and multivariable Mendelian randomization study.

Type 2 diabetes (T2D) is a global health burden, more prevalent among individuals with attention deficit hyperactivity disorder (ADHD) compared to the general population. To extend the knowledge base on how ADHD links to T2D, this study aimed to estimate causal effects of ADHD on T2D and to explore mediating pathways. We applied a two-step, two-sample Mendelian randomization (MR) design, using single nucleotide polymorphisms to genetically predict ADHD and a range of potential mediators. First, a wide range of univariable MR methods was used to investigate associations between genetically predicted ADHD and T2D, and between ADHD and the purported mediators: body mass index (BMI), childhood obesity, childhood BMI, sedentary behaviour (daily hours of TV watching), blood pressure (systolic blood pressure, diastolic blood pressure), C-reactive protein and educational attainment (EA). A mixture-of-experts method was then applied to select the MR method most likely to return a reliable estimate. We used estimates derived from multivariable MR to estimate indirect effects of ADHD on T2D through mediators. Genetically predicted ADHD liability associated with 10% higher odds of T2D (OR: 1.10; 95% CI: 1.02, 1.18). From nine purported mediators studied, three showed significant individual mediation effects: EA (39.44% mediation; 95% CI: 29.00%, 49.73%), BMI (44.23% mediation; 95% CI: 34.34%, 52.03%) and TV watching (44.10% mediation; 95% CI: 30.76%, 57.80%). The combination of BMI and EA explained the largest mediating effect (53.31%, 95% CI: -1.99%, 110.38%) of the ADHD-T2D association. These findings suggest a potentially causal, positive relationship between ADHD liability and T2D, with mediation through higher BMI, more TV watching and lower EA. Intervention on these factors may thus have beneficial effects on T2D risk in individuals with ADHD.

Common Genetic Influence on the Relationship Between Gaming Addiction and Attention Deficit Hyperactivity Disorder in Young Adults: A Twin Study.

Although the relationship between gaming addiction (GA) and attention deficit hyperactivity disorder (ADHD) is well established, the causal mechanism of this relationship remains ambiguous. We aimed to investigate whether common genetic and/or environmental factors explain the GA-ADHD relationship. We recruited 1413 South Korean adult twins (837 monozygotic [MZ], 326 same-sex dizygotic [DZ], and 250 opposite-sex DZ twins; mean age = 23.1 ± 2.8 years) who completed an online survey on GA and related traits. Correlational analysis and bivariate model-fitting analysis were conducted. Phenotypic correlation between GA and ADHD in the present sample was 0.55 (95% CI [0.51, 0.59]). Bivariate model-fitting analysis revealed that genetic variances were 69% (95% CI [64%, 73%]) and 68% (95% CI [63%, 72%]) for ADHD and GA respectively. The remaining variances (ADHD: 31%; GA: 32%) were associated with nonshared environmental variances, including measurement error. Genetic and nonshared environmental correlations between ADHD and GA were 0.68 (95% CI [0.62, 0.74]) and 0.22 (95% CI [0.13, 0.30]) respectively, which indicates that shared genes can explain 82% of the phenotypic correlation between ADHD and GA. Our study demonstrated that the ADHD-GA association was largely due to shared genetic vulnerability.

Mengoptimalkan Pembelajaran Bagi Anak Dengan Adhd Melalui Pendekatan Inklusif di Sekolah Dasar

Inclusive education has become a focus of attention in supporting the successful learning of all students, including those with Attention Deficit Hyperactivity Disorder (ADHD). Children with ADHD face special challenges in managing their attention, impulsivity, and energy, requiring appropriate learning approaches. This research aims to investigate and identify the optimal implementation of an inclusive approach in supporting the learning of children with ADHD in elementary schools. Qualitative research methods were used to explore the experiences of educators, school staff, and parents in facing the learning challenges of children with ADHD. The results show that inclusive approaches implemented in elementary schools can play a key role in creating a supportive learning environment for children with ADHD.

TRATAMENTO COM METILFENIDATO E LISDEXANFETAMINA EM ADULTOS COM TDAH: UMA REVISÃO DA LITERATURA

Introduction: Attention Deficit Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder that, although frequently diagnosed in childhood, can persist into adulthood. ADHD has negative impacts on the quality of life and functioning of daily activities of individuals with this pathology. Treatment aims to improve the clinical and social condition and pharmacological treatment associated with non-pharmacological measures is recommended. Among pharmacotherapy, psychostimulants are the most recommended, with the first and second drugs being methylphenidate (Ritalin, Concerta) or lisdexamfetamine (Venvanse), respectively. However, these medications can have different effects, especially when consumed in the long term. Methodology: Articles published in journals indexed in the Scientific Electronic Library Online (SCIELO), National Library of Medicine/NLM (MEDLINE), UpToDate and National Library of Medicine/NLM (PUBMED) databases and websites recognized worldwide in the period 2014 were evaluated. to 2024. Results: After completing the data collection phase, 47 relevant articles were identified to compose the analysis of the proposed topic. Discussion: Based on the articles cited, it was observed that psychostimulants have good efficacy in treating ADHD, however, few studies have evaluated their long-term effects and with a significant number of study participants. Conclusion: Adults with ADHD should receive adequate treatment, aiming for a better quality of life and both methylphenidate and lisdexamfetamine are good therapeutic options, proving to be relatively effective and safe.

Persistent organic pollutants and developmental trajectories of ADHD symptoms: The Rhea cohort study

Abstract Background Prenatal exposure to persistent organic pollutants (POPs) has been linked to elevated symptoms related to attention deficit hyperactivity disorder (ADHD) in a few studies, but findings remain inconclusive. We aimed to explore how prenatal exposure to POPs affects the developmental course of ADHD symptoms from early childhood to adolescence in the Rhea cohort in Crete, Greece. Methods We determined concentrations of HCB, DDE, and PCBs in first-trimester maternal serum. Child ADHD symptoms were reported by mothers using the ADHD Test at 4 years and the Conners’ Parent Rating Scale at 6, 11 and 15 years. Group-Based Trajectory Modeling was used to classify 551 participants into 4 distinct groups: Stable low (60.1%), Stable high (9.6%), Low-increasing (14.6%), and High-decreasing (15.7%) symptoms. Adjusted multinomial regression models were applied to assess the risk of being grouped into an adverse developmental trajectory as compared to the reference group (stable low), in relation to prenatal POP exposure in 465 children. The analyses were performed in sex-specific manner. Results Prenatal HCB exposure was associated with elevated risk of being grouped in the stable high ADHD symptoms trajectory only in girls (RRR [95%CI]: 2.0 [1.04, 3.82]). Overall, exposure to DDE and sum of PCBs was linked to decreased risk of membership in an adverse ADHD symptoms trajectory. More specifically, in utero exposure to DDE and sum of PCBs was associated with lower risk of being grouped in the low-increasing trajectory for boys (RRR [95%CI]: 0.7 [0.54, 0.95] and 0.5 [0.32, 0.88], respectively) and in the high-decreasing symptoms group for girls (RRR [95%CI]: 0.6 [0.44, 0.84] and 0.5 [0.30, 0.93], respectively). Conclusions The findings suggest that prenatal exposure to HCB is linked to increased risk of stable high ADHD symptoms from preschool age and up to adolescence. The association was pronounced only in girls, a group for which less is understood in relation to ADHD. Key messages • Prenatal exposure to HCB increases the risk of persistently high ADHD symptoms from preschool age to adolescence. • The impact of prenatal HCB exposure on ADHD symptoms is evident in girls.

Environmental burden of disease related to pyrethroid-insecticide exposure and neurodevelopmental toxicity in Europe based on human biomonitoring

Abstract As indicated by human biomonitoring (HBM) studies, exposure to pyrethroids is widespread in Europe with significantly higher exposure observed in children compared to adults. Epidemiological, toxicological, and mechanistic studies raise concerns about potential health effects in humans and, particularly, behavioral disorders such as attention deficit hyperactivity disorder (ADHD) in children at low levels of exposure. Based on an exposure-response function from a single European study and on available quality-assured and harmonized HBM data collected in France, Germany, Iceland, Switzerland, and Israel, an initial estimate of the environmental burden of disease for ADHD associated with pyrethroid exposure (measured by the metabolite 3-phenoxybenzoic acid) was made for individuals aged 0-19 years. The estimated yearly number of prevalence-based disability-adjusted life years (DALYs) per million inhabitants due to ADHD were 34 DALYs for Israel, 26 DALYs for France, 14 DALYs for both Switzerland and Iceland, and 4 DALYs for Germany. Additionally, a substantial number of ADHD cases, averaging 18%, were associated with pyrethroid exposure. Yet, these figures should be interpreted with caution given the uncertainty of some input parameter. In addition to burden of disease estimates due to ADHD, the associated burden of autism-spectrum disorder (ASD) due to pyrethroid exposure and the health economic costs attributable to ADHD and ASD will also be investigated further. To ensure adequate follow-up of policy measures and more robust disease burden estimates, more HBM studies are recommended, along with increased efforts to harmonize the design of epidemiological studies to ensure more meaningful meta-analyses of exposure-response functions. This is particularly important for pyrethroids as more evidence on potential adverse health effects is continuously emerging.

Gambling disorder and its associated factors in university students

Abstract Background Gambling disorder (GD) is defined as persistent and uncontrollable gambling behaviour that has negative effects on an individual’s life. This can lead to financial problems, poor academic performance, and health problems. GD has been associated with psychological disorders like depression, anxiety, and attention-deficit hyperactivity disorder (ADHD). We aimed to examine the gambling disorder and its associated factors in university students. Methods We conducted a cross-sectional study among students at a university in Eskisehir (Türkiye) in 2024. A stratified random sample design was used. Five faculties were randomly selected. A total of 1,201 students were included according to the stratum weight of the faculties. A questionnaire including sociodemographic characteristics, South Oaks Gambling Screen (SOGS), and Adult ADHD Self-Report Scale (ASRS) was applied. Data were analysed through descriptive statistical analyses and multivariate logistic regression models. Results The mean age was 21.5±2.8 years, and 46.8% were male. While 48.7% of the students stated that they had gambled at least once, 2.2% had a gambling disorder. The three most common types of gambling played by students were stock market (28.2%), bet on sports (22.0%), and scratch cards (18.2%). In multivariate analysis, being male (Odds ratio-OR:6.5, 95%CI:1.4-29.8), having lost years during education (OR:2.7, 1.1-6.8), having relatives with gambling problems (OR:8.0, 1.8-36.2), investing greater amounts of money in gambling (OR:3.7, 1.0-13.0), and having a high probability of ADHD (OR:4.3, 1.4-12.8) were found to be predictors for GD. Conclusions Although about half of the students had engaged in gambling activities, only a small proportion showed signs of GD. We can conclude that being male, having lost years in education, having relatives with gambling problems, investing larger amounts of money in gambling, and having a higher probability of ADHD are predictors of GD among students. Key messages • Implementing educational campaigns at universities to raise awareness of the potential risks and consequences associated with GD could be beneficial. • It may be helpful if mental health services at the university were equipped to consider mental health conditions such as ADHD, that contribute to GD.

Empowering Social Growth Through Virtual Reality–Based Intervention for Children With Attention-Deficit/Hyperactivity Disorder: 3-Arm Randomized Controlled Trial

Background Attention-deficit/hyperactivity disorder (ADHD) usually begins in childhood and is often accompanied by impairments in social functioning. Virtual reality (VR) has emerged as an adjunctive tool to embed in social skills training to enhance the social skills of children with ADHD, but its effectiveness requires further investigation. Objective This study aims to enhance the social skills of children with ADHD by examining the feasibility and effectiveness of VR-based training in comparison to traditional social skills training. Methods A 3-arm randomized controlled trial was conducted with 90 children with ADHD aged 6-12 years. Participants were randomly assigned to 3 weeks of 12-session VR-based social skills training, traditional social skills training, or a waitlist control group of equivalent duration. Outcome measures included assessments by a clinical psychologist who was blinded to group assignments, the Social Skills Improvement System Rating Scale, the Behavior Rating Inventory of Executive Function, and the Simulator Sickness Questionnaire, conducted at baseline and after the intervention. Results The preliminary results support the feasibility and acceptability of VR training for children with ADHD aged 6-12 years. Analysis showed that the VR and traditional social skills training groups experienced a statistically significant improvement in the clinical psychologist assessment of social skills and parent-rated self-control, initiative, and emotional control after the intervention compared with baseline. The VR group performed significantly better than the traditional social skills group on social skills assessed by clinical psychologists (F2,85=76.77; P<.001) and on parent-rated self-control (F2,85=18.77; P<.001), initiative (F2,85=11.93; P<.001), and emotional control (F2,85=17.27; P<.001). No significant between-group differences were found for parent-rated cooperation and inhibition (all P>.05). Conclusions The findings provide preliminary evidence supporting the feasibility and superior effectiveness of VR-based social skills training compared to traditional approaches for enhancing social skills and related executive functions in children with ADHD. These results suggest that VR may be a valuable tool to embed within social skills interventions for this population. Further research is warranted to explore the long-term impacts and generalizability of these benefits.

Prenatal Alcohol Exposure Disrupts Performance in a Differential Reinforcement of Low Rates Task Specifically in Adolescent Male Rats.

Prenatal alcohol exposure (PAE) can lead to a wide range of adverse effects in humans, including impaired self-control and increased impulsive behavior. Deficits in self-control can interfere with academic performance and have lasting impacts. In the present study, a rodent model of PAE was used to assess impulsivity through operant conditioning. Pregnant rats were assigned to one of three groups: ad-lib control (CON), pair-fed (PF), and alcohol-exposed (ALC). ALC rats were given a liquid diet containing 6% alcohol, PF rats were yoked to an ALC rat and given a CON liquid diet, and CON rats received ad libitum food. Operant conditioning was used to evaluate extinction in adolescents (Experiment 1) and differential reinforcement of low rates (DRL) in adolescents and adults (Experiment 2). PAE resulted in an increase in responses and resets during DRL testing, indicative of impaired self-control, an effect that was only observed in adolescent males. Females, regardless of age, did not show increased impulsivity following PAE. This indicates that children with PAE may exhibit attentional deficits similar to those with attention deficit hyperactivity disorder, with males at a higher risk.

Tablet computer-based cognitive training for visuomotor integration in children with developmental delay: a pilot study

BackgroundImpaired visuomotor integration (VMI) is commonly observed in children with developmental delay (DD). This pilot study aimed to evaluate the effects of tablet computer-based cognitive training on the VMI in children with DD.MethodsThis study included children aged 4 to under 18 years diagnosed with DD. The children participated in a 12-week tablet computer-based visual-spatial and visuomotor training program. They were administered the Mind Rx Kids Program (Brain Academy, Seoul, South Korea). The participants underwent daily 30-min tablet computer-based training for 12 weeks. The primary visuomotor function was measured using the Beery-Buktenica Developmental Test of Visual-Motor Integration, 6th Edition (VMI-6). For secondary outcomes, measurements were taken before and after 12-week treatment using the Quality of Upper Extremity Skills Test (QUEST), Functional Independence Measure for Children (WeeFIM), Childhood Autism Rating Scale (CARS), Attention deficit hyperactivity disorder Rating Scale (ARS), and Child Smartphone Addiction Observer Scale. The Wilcoxon signed-rank test was used to compare the pre- and post-treatment outcomes.ResultsTen children with DD participated in this study. The results of the 12-week tablet computer-based cognitive training showed significant improvements in the raw score, standard score, percentile score, and equivalent age of the Beery VMI-6. Additionally, there were significant improvements in QUEST and WeeFIM scores. Although there were improvements in the CARS, ARS, and smartphone addiction observer scale, these were not statistically significant.ConclusionThis pilot study confirmed that applying tablet computer-based cognitive training to children with DD not only improves VMI, but also enhances fine motor skills and activities of daily living. Furthermore, the results of this study indicate that tablet computer-based cognitive training does not increase digital media addiction. Therefore, children with DD can engage in tablet computer-based cognitive training at home without concerns about digital media addiction.

A New Objective Diagnostic Tool for Attention-Deficit Hyper-Activity Disorder (ADHD): Development of the Distractor-Embedded Auditory Continuous Performance Test

Background/Objectives: Attention-Deficit Hyperactivity Disorder (ADHD) is a prevalent neurodevelopmental disorder characterized by inattention, hyperactivity, and impulsivity. Traditional diagnostic methods, which depend on subjective assessments, often lack precision. This study evaluates the validity and reliability of a newly developed diagnostic tool, the Distractor-Embedded Auditory Continuous Performance Test (da-CPT), which integrates auditory stimuli with distractors to enhance the clinical utility of ADHD diagnosis. Methods: The study included 160 children aged 6–12 years, comprising 80 with a confirmed ADHD diagnosis and 80 controls. All participants completed the da-CPT, a web-based tool designed to assess inattention, hyperactivity, impulsivity, and timing via an auditory-based task. To validate the da-CPT, participants also completed the Conners’ Parent Rating Scale—Revised Short Form (CPRS-R) and either the MOXO or IVA-2 tests. Data were analyzed using ROC curves and statistical correlations to assess sensitivity, specificity, and overall diagnostic accuracy. Results: The da-CPT demonstrated high diagnostic accuracy, with a sensitivity of 91.25% and specificity of 83.75%. ROC analysis indicated that the inattention index had the highest discriminatory power (AUC = 0.881), followed by timing, impulsivity, and hyperactivity (all p < 0.01). Furthermore, the da-CPT scores were strongly correlated with ADHD severity (p < 0.01). Conclusions: This study confirms that the da-CPT is a valid and reliable tool for diagnosing ADHD in children aged 6–12. By incorporating auditory stimuli and distractors, the tool offers a more ecologically valid assessment of ADHD symptoms in clinical settings, improving diagnostic precision and utility.

Impact of a physical exercise intervention on psychological resilience and mental ill-being in medical-naïve children with attention-deficit/hyperactivity disorder: a pilot randomised controlled trial

ABSTRACT The study aimed to evaluate whether a 12-week physical exercise intervention would improve psychological resilience and mental ill-being (e.g. internalising and externalising symptoms) in medical-naïve children with Attention-Deficit/Hyperactivity Disorder (ADHD). In a parallel two-group randomised controlled trial (RCT) design, 30 children between 8–12 years (Mage = 8.62 ± 1.37) formally diagnosed with ADHD were assigned to a 12-week physical exercise intervention group (three sessions per week for 60 mins, moderate-to-vigorous physical activity [MVPA] intensity) or a control group (treatment as usual). Psychological resilience was measured by a self-reported Chinese version of the 25-item Connor-Davidson Resilience Scale, and mental ill-being was assessed by a parent-reported Chinese version of the 113-item Achenbach’s Child Behavior Checklist. The 12-week physical exercise intervention with MVPA level revealed a significant improvement in psychological resilience (F = 4.82, p = .038) and a significant reduction in internalising symptoms (e.g. anxiety/depressed, withdrawn/depressed, and somatic complaints) (F = 7.11, p = .013) and externalising symptoms (e.g. rule-breaking behaviour and aggressive behaviour) (F = 21.09, p < .001) in the intervention group but not in the control group. Moderate correlations were revealed between the changes in psychological resilience and the changes in internalizing (r = -.557, p = .031) and externalising symptoms (r = -.647, p = .009) in the intervention groups (n = 15). The findings of this study provide initial support for the efficacy of physical exercise intervention on psychological resilience and mental ill-being and for the potential mechanisms of psychological resilience under the effects of exercise-induced mental ill-being improvements in children with ADHD.

Molecular Docking, Bioinformatic Analysis, and Experimental Verification for the Effect of Naringin on ADHD: Possible Inhibition of GSK-3β and HSP90

Background/Objectives: One of the most abundant and growing neurodevelopmental disorders in recent decades is attention deficit hyperactivity disorder (ADHD). Many trials have been performed on using drugs for the improvement of ADHD signs. This study aimed to detect the possible interaction of naringin with Wnt/β-catenin signaling and its putative anti-inflammatory and protective effects in the mouse ADHD model based on bioinformatic, behavioral, and molecular investigations. Furthermore, molecular docking was applied to investigate possible interactions with the GSK-3β and HSP90 proteins. Methods: Male Swiss albino mice were divided into four groups, a normal control group, monosodium glutamate (SGL) control, SGL + naringin 50 mg/kg, and SGL + naringin 100 mg/kg. The psychomotor activity of the mice was assessed using the self-grooming test, rope crawling test, and attentional set-shifting task (ASST). In addition, biochemical analyses were performed using brain samples. Results: The results of the SGL group showed prolonged grooming time (2.47-folds), a lower percentage of mice with successful crawling on the rope (only 16.6%), and a higher number of trials for compound discrimination testing in the ASST (12.83 ± 2.04 trials versus 5.5 ± 1.88 trials in the normal group). Treatment with naringin (50 or 100 mg per kg) produced significant shortening in the grooming time (31% and 27% reductions), as well as a higher percentage of mice succeeding in crawling with the rope (50% and 83%, respectively). Moreover, the ELISA assays indicated decreased dopamine levels (0.36-fold) and increased TNF-α (2.85-fold) in the SGL control group compared to the normal mice, but an improvement in dopamine level was observed in the naringin (50 or 100 mg per kg)-treated groups (1.58-fold and 1.97-fold). Similarly, the PCR test showed significant declines in the expression of the Wnt (0.36), and β-catenin (0.33) genes, but increased caspase-3 (3.54-fold) and BAX (5.36-fold) genes in the SGL group; all these parameters were improved in the naringin 50 or 100 mg/kg groups. Furthermore, molecular docking indicated possible inhibition for HSP90 and GSK-3β. Conclusions: Overall, we can conclude that naringin is a promising agent for alleviating ADHD symptoms, and further investigations are required to elucidate its mechanism of action.

Validity of specific CPT indices in differentiating school-aged children previously diagnosed with attention deficit/hyperactivity disorder from school-aged children with non-attention deficit/hyperactivity disorder in general education classrooms: a case control study

BackgroundContinuous performance tests (CPTs) are a popular tool for evaluating the symptoms of attention-deficit/hyperactivity disorder (ADHD). Performance measurements are typically linked to the biological features and cognitive functions of individuals. To determine the validity of specific CPT indices in differentiating between school-aged children with ADHD from with non-ADHD, each student’s sex, chronological age, and cognitive abilities should be considered.MethodsIn this prospective case–control study, a total of 30 non-ADHD students and 26 with ADHD who were aged 6 to 12 years were from general education classrooms. All students completed the Continuous Performance Tests (CPTs) and the Peabody Picture Vocabulary Test-revised (Mandarin-Chinese version). Demographic data were collected from the students’ parents.ResultsDetectability, Omissions, Commissions, and Hit Reaction Time Standard Deviation (HRT SD) yielded higher T-scores in children with ADHD than those without. Compared with non-ADHD students, those with ADHD had higher classification scores for Detectability, Omissions, Perseverations, and HRT SD. For each CPT index, after individual factors were controlled for, logistic regression revealed that only students with positive scores for Detectability, Omission, and HRT SD (adjusted odds ratios = 4.627, 9.977, and 3.908, Ps < 0.05) were likely to receive a diagnosis of ADHD. Furthermore, after individual characteristics were controlled for, Logistic regression also revealed that the cumulative positive scores of the Detectability, Omission, or and HRT SD remained associated with an increased risk of ADHD (adjusted odds ratio = 3.116, P < 0.01).ConclusionsCompared with school-aged children with non-ADHD in general education classrooms, those with ADHD exhibited significantly lower performance in inattention-related CPT indices. To reach an accurate diagnosis through CPTs, clinicians should pay attention to Detectability, Omission, and HRT SD. Compared with other CPT indices, Detectability, Omission, and HRT SD may function as more suitable indicators for distinguishing between school-aged children with and non-ADHD in general education classrooms. These indicators are robust and unobscured by individual characteristics.

A novel MAOA gene variant: Brunner syndrome, a rare syndrome, is associated with a wide range of psychiatric symptoms.

Brunner syndrome is a rare genetic disorder that associated with mutations in the MAOA gene. It has been linked to a number of psychiatric disorders. We present detailed information on psychiatric evaluation of a case carrying a novel MAOA gene variant of p.(Thr408Met). The patient was referred to our clinic with a history of attention problems, motor coordination difficulties and a tendency to bite objects. Following a comprehensive psychiatric evaluation, the patient was diagnosed with developmental coordination disorder, articulation disorder and attention deficit hyperactivity disorder (ADHD). MAOA mutations are rarely reported in the literature. To date, a total of 23 MAOA gene variants, mostly missense variants, have been reported through the HGMD database (Professional 2023.4). Neurodevelopmental symptoms may vary in severity and diversity among patients with Brunner syndrome. Different degrees of intellectual disability have been found in previously reviewed cohorts of Brunner syndrome. In our affected patient, cognitive development and academic achievement were at a similar level to his peers. Additionally, our patient exhibited symptoms suggestive of developmental coordination disorder. Our findings show that genetic mutations in MAOA can lead to a wide range of clinical symptoms and underline the need for comprehensive genetic and clinical evaluations.

Clinical Utility of Virtual Kitchen Errand Task for Children (VKET-C) as a Functional Cognition Evaluation for Children with Developmental Disabilities

Background/Objectives: This study evaluated the clinical utility of a virtual reality (VR)-based kitchen error task for children (VKET-C) to assess functional cognition in children. Methods: In total, 38 children aged 7–12 years were included, comprising 23 typically developing (TD) children and 15 children with developmental disabilities (DDs), including autism spectrum disorder, attention deficit hyperactivity disorder, and intellectual disability. While performing the VKET-C, performance errors were analyzed. The Stockings of Cambridge (SOC) and Spatial Working Memory (SWM) tasks from the Cambridge Neuropsychological Test Automated Battery (CANTAB) were used to assess cognitive function. The Brunner–Munzel test was performed to compare performance errors between the TD and DD groups, and correlations between performance errors and cognitive measures were analyzed. Results: Omission and commission errors were significantly different between the groups (p &lt; 0.001), with no significant difference in motor errors (p &gt; 0.05). Omission errors were correlated with the initial thinking time mean (ITMN) in all items of the SOC task and the between errors (BE) of the SWM task. Commission errors were correlated with the ITMN in the difficult items of the SOC task and the BE of the SWM task. Additionally, motor errors were significantly correlated with problems solved in minimum moves (PSMM) and ITMN in the difficult items of the SOC task and BE in the SWM task. Conclusions: The VKET-C shows promise as an effective tool for assessing executive function and working memory in children with DDs, offering an engaging and ecologically valid alternative to traditional methods.

Bidirectional influence between benign prostatic hyperplasia, prostate cancer, and prostatitis and mental disorders: two-sample and multivariate mendelian randomization analyses

Background We aimed to use Mendelian randomization (MR) to determine the causality between fifteen major mental disorders (MDs) and benign prostatic hyperplasia (BPH), prostate cancer (PCa), and prostatitis. Methods The main MR analysis was performed using the inverse variance-weighted (IVW) method. Results The study found that insomnia (odds ratio [OR], 1.6190; p = .0017) was significantly associated with an increased risk of BPH, and mood disorders (OR, 1.1590; p = .0221) was nominally associated with an increased risk of BPH. Conversely, BPH was suggestively associated with a low epilepsy risk (OR, 0.9988; p = .0043), and was nominally associated with an increased risk of insomnia (OR, 1.0061; p = .0291). Furthermore, attention deficit hyperactivity disorder (ADHD) was suggestively associated with a low PCa risk (OR = 0.9474; p = .0058). However, no causal relationship was observed between PCa and MDs. Finally, anorexia nervosa (OR, 1.1686; p = .0248) and depression (OR, 336.5383; p = .0308) were nominally positively correlated with prostatitis. Prostatitis was suggestively associated with increased risk of ADHD (OR, 1.0868; p = .0413). Conclusion Our findings provide clinicians with a basis for developing programs to prevent or treat MDs and prostatic diseases.
