[PMID: 38697886 DOI: 10.1016/j.jagp.2024.04.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/09/2024] [Revised: 04/08/2024] [Accepted: 04/08/2024] [Indexed: 05/05/2024]
Abstract
OBJECTIVES Past reports have suggested that attention-deficit/hyperactivity disorder (ADHD) may be a risk factor for Lewy body disease (LBD). To confirm this relationship, we conducted the present study. DESIGN A prospective observational cohort study with a follow-up to 15 years. SETTING The subjects were recruited from cognitive neurology clinics, where they attended for a cognitive complaint or health check-up. PARTICIPANTS Two groups of subjects: ADHD adults and healthy subjects. MEASUREMENTS The risk of dementia and LBD was estimated with Kaplan-Meier analysis comparing for the presence or absence of ADHD with the log-rank test. Predictors of conversion were assessed through separate univariate and multivariate Cox regression analyses, adjusting for several variables. RESULTS The baseline sample consisted of 161 subjects with ADHD and 109 without ADHD. At the end of the follow-up, 31 subjects developed dementia, 27 cases in the ADHD group and 4 in comparison group. Dementia with Lewy bodies (DLB) was the most frequent type (N:20) of which 19 corresponded to the ADHD group. The incidence of non-amnestic-MCI in the ADHD group was higher representing 67.1 % of these subjects (N:108), and 17.4% (N:19) of healthy cases. The hazard ratios for dementia and LBD in the multivariate adjusted model were 3.33 (95% CI 1.0915 to 10.1699) and 54.54 (95% CI 7.4849 to 397.5028), respectively in the ADHD group. CONCLUSIONS This study showed that adult ADHD is independently associated with an increased risk of LBD, dementia, and na-MCI. Future studies should clarify this relationship to develop preventive measures for these patients.

[PMID: 38959718 DOI: 10.1016/j.sleep.2024.06.015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/05/2024] [Revised: 06/09/2024] [Accepted: 06/14/2024] [Indexed: 07/05/2024]
Abstract
BACKGROUND Sleep is impaired in children with attention-deficit/hyperactivity disorder (ADHD). However, population-based examination of indicators of sleep insufficiency and bedtime irregularity is limited. This investigation examined associations between ADHD, weeknight sleep insufficiency, and bedtime irregularity in a nationally-representative child sample, and indicators of these sleep outcomes in ADHD. METHODS Parents of children aged 3-17 years with ADHD (n = 7671) were surveyed through the 2020-2021 National Survey of Children's Health. Inverse probability of treatment weighting generated a weighted matched control sample (n = 51,572). Weighted generalized linear models were performed without and with age-stratification to examine associations between ADHD and sleep, adjusting for sociodemographics in the full sample, and between nineteen sociodemographic and clinical variables and sleep in ADHD. RESULTS Having ADHD was associated with increased odds of sleep insufficiency and bedtime irregularity relative to controls, even after adjusting for sociodemographic variables. In ADHD, older age was associated with lower sleep insufficiency and greater bedtime irregularity. Black race, increased poverty, higher ADHD severity, depression, and increased screen time were associated with greater sleep insufficiency and bedtime irregularity. Adverse childhood experiences (ACEs) were associated with greater sleep insufficiency. Behavioral/conduct problems, female sex, and absence of both ADHD medication use and ASD diagnosis were associated with poorer bedtime irregularity. Age-stratified results are reported in text. CONCLUSIONS Children with ADHD face heightened risk for insufficient sleep and irregular bedtimes. Findings suggest intervention targets (e.g., Black race, poverty, depression, screen time) to improve both sleep insufficiency and bedtime irregularity. Results highlight ACEs and behavioral/conduct problems as targets to improve sleep insufficiency and bedtime regularity, respectively. Age-stratified findings are discussed.

Abstract
Infection and lockdowns resulting from COVID-19 have been suggested to increase the prevalence and treatment rates of Attention Deficit/Hyperactivity Disorder (ADHD). To accurately estimate the pandemic's effects, pre-pandemic data can be used to estimate diagnosis and treatment rates during the COVID-19 years as if the COVID-19 pandemic did not occur. However, accurate predictions require a broad dataset, both in terms of the number of cases and the pre-pandemic timeframe. In the current study, we modeled monthly ADHD diagnosis and treatment rates over the 18 years preceding the COVID-19 pandemic. The dataset included ∼3 million cases for individuals aged 6 to 18 from the Clalit Health Services' electronic database. Using a trained model, we projected monthly rates for post-lockdown and post-infection periods, enabling us to estimate the expected diagnosis and treatment rates without the COVID-19 pandemic. We then compared these predictions to observed data, stratified by age groups, gender, and socioeconomic status. Our findings suggest no influence of the COVID-19 pandemic on ADHD diagnosis or treatment rates. We show that a narrower timeframe for pre-COVID-19 data points can lead to incorrect conclusions that COVID-19 affected ADHD diagnosis rates. Findings are discussed, given the assumed impact of the COVID-19 pandemic on ADHD.

Eur Child Adolesc Psychiatry 2024:10.1007/s00787-024-02550-3. [PMID: 39126498 DOI: 10.1007/s00787-024-02550-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/05/2023] [Accepted: 07/30/2024] [Indexed: 08/12/2024]
Abstract
Non-specific effects of methylphenidate treatment, including expectancy and regression to the mean effects, contribute to the overall effect of methylphenidate on attention-deficit/hyperactivity disorder (ADHD) symptoms. Knowledge on the extent to which non-specific effects contribute to the overall effect and whether regression to the mean explains part of the non-specific effects, is currently lacking. A double-blind, randomized, placebo-controlled, cross-over trial was used to compare parent and teacher ratings of child ADHD symptoms at baseline and during treatment with placebo and 5, 10, 15 and 20 mg of methylphenidate, twice daily. Participants were 5-13-year-old children with a DSM-5 diagnosis of ADHD (N = 45). The extent to which non-specific effects contributed to the effects of methylphenidate was determined by ADHD symptom reductions observed with placebo versus reductions observed with active doses of methylphenidate. The influence of regression to the mean was examined by estimating the contribution of baseline ADHD symptom severity to the effects observed with placebo treatment. Data were analyzed using multilevel analyses. We observed significant non-specific effects of methylphenidate for parent-rated ADHD symptoms, but not for teacher-rated symptoms. For parent reported hyperactive/impulsive symptoms, higher baseline symptoms predicted larger effects with placebo, indicating regression to the mean effects. For parent-reports, a significant part of the overall effect of methylphenidate treatment is explained by non-specific effects. Our findings stress the importance of taking non-specific effects into account when evaluating methylphenidate treatment, by including teacher-reports and using a double baseline assessment during titration. Comparing active medication with a placebo in the titration trial has the potential to identify non-specific effects.

Abstract
OBJECTIVE The study aims to examine family functionality, emotion regulation difficulties, preference for loneliness, social exclusion, internalizing and externalizing disorders, and executive functions in children with Attention Deficit Hyperactivity Disorder (ADHD) and Cognitive Disengagement Syndrome (CDS) and compare with ADHD, and ADHD+ Oppositional Defiant Disorder (ODD). METHOD This study included 842 children aged 8-12 years. The subjects were categorized according to DSM-V as ADHD (n = 246), ADHD + ODD (n = 212), ADHD + CDS (n = 176), and Control group (n = 207). The solitude and social exclusion, difficulties in emotion dysregulation and Barkley SCT scales, Child Behavior Checklist, family assessment device, and Central Vital Signs (CNSVS) test were used. RESULTS According to the study, children with ADHD + CDS had higher rates of internalizing disorders. They also preferred being alone and experienced more difficulty communicating with their parents and solving problems within the family. Additionally, these children had difficulty recognizing and understanding the emotional reactions of others. The ADHD + ODD group presented a poorer performance on CNSVS domain tests except for the psychomotor speed test than other groups. Also, ADHD + CDS children had the lowest psychomotor speed scores and lower scores on reaction time and cognitive flexibility than pure ADHD children. CONCLUSION This study will contribute to the etiology, treatment, and clinical discrimination of ADHD + CDS.

Abstract
Attention deficit hyperactivity disorder (ADHD) with and without subclinical epileptogenic discharges (SED) have been suggested to negatively affect cognitive abilities of children with ADHD. The role of brain-derived neurotrophic factor (BDNF) and its precursor proBDNF in ADHD is in need of being investigated. The aims were to evaluate the levels of serum BDNF, proBDNF and the proBDNF/BDNF ratio in addition to the potential impacts of SED on the children's cognitive abilities and the severity of ADHD. The included participants with ADHD were 30 children with normal electroencephalogram (EEG) (G1) and 30 children with SED (G2), together with 30 healthy children (G3). The cognitive abilities and severity of the disorder were evaluated. The biochemical measures were determined by ELISA. The presence of coexisting SED and nocturnal enuresis has led to a deleterious effect on cognitive processes but not on the severity. The focal epileptogenic discharge was the most common among children in G2. The levels of BDNF in Groups 1 and 2 were less than those in G3. The higher proBDNF/BDNF ratio could be related to the low BDNF levels rather than high proBDNF levels. The findings of this study highlight the importance of investigating the presence of SED and nocturnal enuresis in children with ADHD. Targeting strengthening of cognitive abilities in children with coexisting ADHD and SED is advised. The role of proBDNF in the pathophysiology of ADHD needs further investigation.

Abstract
Oppositional defiant disorder (ODD) and attention-deficit/hyperactivity disorder (ADHD) are two of the most common childhood mental disorders, and they have substantial comorbidity. The developmental precursor model has long been widely used to explain the mechanisms of comorbidity between ODD and ADHD, however whether it is equally effective at the symptomatic level is unclear. Therefore, this study aimed to (a) examine the stability of the ODD and ADHD comorbidity network in a longitudinal sample of high-risk children in China; and (b) examine the longitudinal relationship between the ODD and ADHD symptom networks based on a developmental precursor model. Two hundred sixty-three Chinese children aged 6 to 13 years with ODD and/or ADHD were assessed for symptoms of ODD and ADHD in two surveys conducted 1 year apart. We used data from these two time points to construct two cross-sectional networks and a cross-lagged panel network (CLPN) to explore the symptom network for comorbidity of ODD and ADHD. The analysis shows that: (1) the two cross-sectional networks are highly similar in terms of structure, existence of edges, centrality estimates, and the invariance test shows that there is no significant difference between them. The symptoms "follow through", "interrupts/intrudes", "difficulty playing quietly" and "concentration" had the highest expected influence centrality at both time points. (2) Combined with the results of the cross-sectional and cross-lagged networks, we found that "annoy" and "blame" are potential bridge symptoms between the ODD and ADHD symptom networks. The symptom "annoy" forms a reciprocal predictive relationship with "interrupts/intrudes", while "blame" unidirectionally predicts "close attention". In addition, we found that "vindictive" predicted numerous ADHD symptoms, whereas "angry" was predicted by numerous ADHD symptoms. The findings emphasize the broad predictive relationship between ODD and ADHD symptoms with each other, and that ODD symptoms may lead to activation of the ADHD symptom network and vice versa. These findings suggest that the developmental precursor model at the symptom level may partially explain the comorbidity mechanisms of ODD and ADHD, and future studies should further investigate the underlying multiple mechanisms.

Abstract
INTRODUCTION Access to care for children and adolescents affected by ADHD in France remains below the levels attained in most industrialised countries. To contribute to improving ADHD care in France, we assessed existing ADHD knowledge among medical doctors (MDs) and described associated care pathways in two large French regions in 2021. We produced tools to evaluate the regional impact of implementing a stepped-care pathway for ADHD. METHODS A SurveyMonkey® study was sent to professionals from two regions in France accounting for 14 million inhabitants, allowing them to describe their role in child/adolescent ADHD, as well as their representations and knowledge about the disorder. RESULTS Around 9.4% of all MDs potentially involved with children took part in the study; 34.9% considered themselves untrained, 40.5% were involved in ADHD care at a first-tier level, and 19.6% at a second-tier level. Access to a second or third-tier service for ADHD was associated with mean waiting times of 5.7 and 8.5 months, respectively. Initiation of stimulant therapy remained mainly restricted to second or third-tier MDs, and adaptation of dosage or change in the galenic formulation was rarely performed by first-tier MDs (27.2% and 18%, respectively). Training in neurodevelopmental disorders and tier-level were the strongest determinants of knowledge, attitudes and self-assessed expertise about ADHD. CONCLUSIONS This study provides insight into training needs for MDs regarding healthcare pathways in ADHD and should support the implementation of health policies, such as a stepped healthcare access for ADHD. The study design and dissemination have been validated and will be available in France and other countries facing similar obstacles in care pathways for ADHD. Official recommendations on ADHD in children and adults are being updated in France, and our data and the survey design will be a starting point for their implementation.

Abstract
This study aimed to validate a novel parent-report measure of ADHD symptom inflation, the Parent-Reported ADHD Symptom Infrequency Scale (PRASIS), in a clinical sample. The PRASIS is composed of an Infrequency subscale and an ADHD subscale. Online participants were assigned to one of three groups: mothers of children with diagnosed ADHD (n = 110), mothers of children with diagnosed ODD and/or anxiety (n = 116), and mothers of children without ADHD, ODD, or anxiety. The third group was then randomized to either receive instructions to complete the questionnaire honestly (controls, n = 164) or to complete the questionnaire as if they were trying to convince a provider that their child has ADHD (simulators, n = 141). Results indicated good to excellent internal consistency (INF α = .83, ADHD Total α = .93); strong convergent validity of the PRASIS ADHD scale with the ADHD Rating Scale-5 (r(529) = .85, p < .001); excellent group discrimination of the PRASIS Infrequency scale and the PRASIS ADHD scale (η2 = 0.38-0.42); and specificity of 86.7, sensitivity of 67.4%, and an AUC of .86 for the Infrequency scale. Overall, these outcomes supported the utility of the PRASIS in samples including mothers of children with psychiatric diagnoses of ODD and/or anxiety.

Köder F, Rummelhoff C, Garraffa M. Comparing pragmatic abilities across multiple languages in adults with ADHD: Insights from a self-report questionnaire. CLINICAL LINGUISTICS & PHONETICS 2024:1-16.

Abstract
Attention-Deficit/Hyperactivity Disorder (ADHD) is associated with pragmatic language impairments in children, but less is known about the communicative abilities of adults with ADHD, especially when using a second or third language. In this study, we developed a questionnaire to collect self-report measures of a set of pragmatic skills in a person's first, second and third language, comparing adults with and without an ADHD diagnosis. One hundred seventy-nine multilingual adults with (N = 91) and without ADHD (N = 88) completed the survey. As predicted, adults with ADHD reported more pragmatic difficulties than the control group. More specifically, people with ADHD showed pronounced impairments in regulating their behaviour in spoken interactions in the form of excessive talking, frequently interrupting others, and speaking without thinking first. Notably, these types of hyperactive and impulsive behaviours were significantly reduced when people with ADHD communicated in a second or third language. For pragmatic difficulties related to inattention such as concentrating on a conversation, both groups tended to be more inattentive in their third language compared to their first and second language. The understanding of non-literal language was only affected by ADHD in the first language and was generally more taxing in a language with lower proficiency levels. Our study contributes to a more nuanced understanding of how ADHD affects different kinds of communicative abilities in multilingual adults. It also has implications for clinical practice, highlighting the importance of assessing symptoms of inattention, hyperactivity, and impulsivity in a person's dominant language.

Abstract
Sickle cell disease (SCD) is a genetic blood condition that places youth at increased risk for deficits in complex attention suggestive of increased risk for Attention-Deficit/Hyperactivity Disorder (ADHD). We used systematic screening to assess the prevalence of ADHD in a clinic-based sample of youth with SCD and explored factors related to ADHD. Caregivers of 107 children with SCD (ages 7-11 years) completed routine psychosocial screening which included inattentive symptoms of ADHD. Follow-up diagnostic procedures were completed for patients with elevated inattentive symptoms to assess for ADHD diagnoses. Biomedical and social-environmental variables were examined from the screening and medical records. Twenty-six percent of patients showed elevated inattentive symptoms with 13% meeting diagnostic criteria for ADHD diagnoses. Most children (75%) who met criteria for ADHD had not been previously diagnosed. Disease severity did not predict inattentive symptoms or ADHD diagnoses, though a measure of chronic inflammation was associated with ADHD. Family functioning was related to elevated inattentive symptoms but not ADHD diagnoses. Children with SCD show relatively high rates of ADHD with many cases not detected through routine care. Screening for ADHD as part of hematology care may be a feasible strategy to improve identification and access to intervention.

Psychometric properties of the self-report version of the Strengths and Weaknesses of ADHD Symptoms and Normal Behavior Scale in a sample of Hungarian adolescents and young adults. Front Psychiatry 2024; 15:1330716. [PMID: 39026526 PMCID: PMC11255780 DOI: 10.3389/fpsyt.2024.1330716] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/31/2023] [Accepted: 06/10/2024] [Indexed: 07/20/2024] Open
Abstract
The Strengths and Weaknesses of ADHD Symptoms and Normal Behaviour Scale (SWAN) measures the full spectrum of attention and activity symptoms, not just the negative end of the distribution. Previous studies revealed strong psychometric properties of the parent and teacher report versions; however, there is little research on the new self-report form of the SWAN. Therefore, our research aimed to explore the psychometric characteristics of the SWAN self-report. A non-clinical sample of young women (N = 664, mean age: 20.01 years, SD: 3.08 years) completed the SWAN self-report, the Strengths and Difficulties Questionnaire (SDQ) and the Mental Health Continuum Short Form (MHC-SF). We tested several models using confirmatory factor analyses to assess the factorial validity of the SWAN self-report. Distributional characteristics, convergent, and predictive validity were assessed. A bifactor model with a general factor and a specific inattention factor (bifactor-1) provided the best fit in our data (CFI = 0.977, TLI/NFI = 0.972, RMSEA = 0.053 [90% CI: 0.047 - 0.059], SRMR = 0.061, ω = 0.90). The reliability of the general ADHD factor was good (ωh = 0.87), and the specific inattention factor was acceptable (ωh = 0.73). The distribution of the SWAN self-report scores did not differ from the normal distribution. A strong correlation between the SWAN and the SDQ Hyperactivity subscale was found. The analyses revealed good predictive validity. Our results suggest that the SWAN self-report is a valuable tool for assessing symptoms of ADHD in adolescents and young adults.

Abstract
Recent research has increasingly emphasized the function of the microbiome in human health. The gut microbiome is essential for digesting food and seems to play a vital role in mental health as well. This review briefly overviews the gut microbiome and its interplay with the central nervous system. We then summarize some of the latest findings on the possible role of the microbiome in psychiatric disorders in children and adolescents. In particular, we focus on autism spectrum disorder, attention-deficit/hyperactivity disorder, anorexia nervosa, bipolar disorder, and major depressive disorder. Although the role of microbiota in mental development and health still needs to be researched intensively, it has become increasingly apparent that the impact of microbiota must be considered to better understand psychiatric disorders.

Abstract
Background Attention-deficit/hyperactivity disorder (ADHD) in children can adversely impact parental quality of life (QoL). However, limited research exists among families in Saudi Arabia, especially in understudied regions like Jazan. This study was designed to determine the QoL in parents of children with ADHD in Jazan, Saudi Arabia. Methodology This cross-sectional study was conducted in the Jazan region of Saudi Arabia from June 2023 to December 2023. Online questionnaires were used to collect data from parents of children with ADHD residing in the country. A structured questionnaire was developed in consultation with the National Institute for Children's Health Quality (NICHQ) guidelines. The total sample size was 276. The study participants were recruited through convenient non-random snowballing sampling where the promotion of the questionnaire web link aided in reaching the required sample size of the study. Participants aged more than 18 years, residents of the Jazan area, and both genders were included. R software was used for data analysis. Results The study, involving 275 participants, revealed that 45 (16%) children were diagnosed with ADHD by doctors, with a higher prevalence among males 36 (80%). The NICHQ scale identified ADHD in 50 (18%) participants, with the predominant subtypes being inattentive 28 (56%), hyperactive/impulsive 28 (56%), and combined 19 (38%). The median QoL score was 8.6, with good QoL reported by 51.27% of parents and poor QoL by 48.73%. Gender significantly influenced QoL (p < 0.01), with 57% of males and 43% of females reporting good QoL, while 61% of females and 39% of males reported poor QoL. Oppositional defiant symptoms were significantly associated with poorer QoL (p < 0.05). There was a notable alignment between ADHD diagnoses from parental reports and the NICHQ scale. Conclusions This cross-sectional study found that parents of children with ADHD behaviors, especially those exhibiting oppositional defiant symptoms, experienced significantly lower QoL, particularly in personal fulfillment and psychosocial well-being. The findings emphasize the need for culturally tailored psychosocial interventions in Saudi Arabia to improve parental coping and QoL, benefiting overall family well-being and child outcomes.

Abstract
BACKGROUND This study aims to explore the genetic architecture shared between Attention-Deficit/Hyperactivity Disorder (ADHD) and risk behavior. METHODS Based on the latest large-scale Genome-wide association studies (GWAS), we firstly employed Linkage disequilibrium score regression (LDSC) and Local Analysis of Variant Association (LAVA) to investigate the genetic correlation between risk behavior and ADHD. Then, we conducted cross-trait analysis to identified the Pleiotropic loci. Finally, bidirectional Mendelian randomization analysis (MR) was applied to examine the causal relationship. RESULTS We found a significant positive genetic correlation between ADHD and risk-taking behavior (rg = 0.351, p = 6.50E-37). The cross-trait meta-analysis identified 27 significant SNPs shared between ADHD and risk behavior. The most significant locus, located near the CADM2 gene on chromosome 3, had been identified associated with this two trait (pADHD = 3.07E-05 and prisk-taking behavior = 2.47E-30). The same situation can also be observed near the FOXP2 gene on chromosome 7 (rs8180817, pmeta = 5.72E-21). We found CCDC171 gene and other genes played a significant role in ADHD and risk behavior in mRNA level. Bidirectional MR analysis found a causal relationship between them. LIMITATION The majority of our data sources were of European origin, which may limit the generalizability of our findings to other ethnic populations. CONCLUSION This article reveals in depth the shared genetic structure between ADHD and risk-taking behavior, finding a significant positive genetic correlation between ADHD and risk-taking behavior. Providing insights for the future treatment and management of these two traits.

Abstract
Attention-deficit hyperactivity disorder (ADHD) is a common chronic neurodevelopmental disorder characterized by symptoms of inattention, overactivity, and/or impulsiveness. The prevalence of ADHD varies in different settings and there have been voices raised to call for more objective measures in order to avoid over- and underdiagnosing of ADHD. Auditory Brainstem Response (ABR) is a method where click shaped sounds evoke potentials that are recorder from electrodes on the skull of a patient. The aim of this study was to explore possible alterations in the ABR of 29 patients with ADHD compared to 39 healthy controls. We used a forward masked sound. We found differences in ABR that correspond to the thalamic area. The thalamus seems to play an active role in regulation of activity level in ADHD. More research is needed to draw any further conclusions on using ABR as an objective measurement to detect ADHD.

Abstract
Background Attention deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder of childhood characterised by attention deficit, hyperactivity and impulsiveness. The present study was designed to compute the prevalence of ADHD and assess the association of the predetermined demographic variables and ADHD in school-going children aged 6-12 years in rural areas of Konkan. Material and Methods The present study was a descriptive, cross-sectional study. Using the first edition of Vanderbilt's scale - D4 (Teacher's informant) by National Institute for Children's Health Quality (NICHQ) for identifying symptoms of ADHD in children, a questionnaire was filled out for each child with input from their class teacher. These data were then compiled and analysed. Results Out of the 133 participants in the study aged 6-12 years, the gender distribution was 69 boys and 64 girls. The mean age was 9.2 ± 2.3 years. Of which, one student (0.75%) was found to have a predominantly inattentive subtype of ADHD (ADHD-IA). The prevalence was found to be 1.5% (2/133). In addition, one student (0.75%) was found to have a combined ADHD-IA and hyperactive (ADHD-H/I) subtype of ADHD (ADHD-C). The latter was also positive for the anxiety/depression screening scale administered as part of the same questionnaire. The total symptom score for questions 1-18 was 8.44 ± 7.29. Conclusion One of the most common neurodivergent conditions among school-age children is ADHD. Using an easy-to-use questionnaire, teachers and parents can report those experiencing symptoms of ADHD. Early diagnosis and treatment are recommended to avoid complications and aid in the improvement of quality of life.

Abstract
Background Microcytic anemia due to iron deficiency is the most common type of anemia in children in Israel and many parts of the world, and has been shown to have negative consequences for the cognitive performance. We aimed to examine the association between microcytic anemia at age 9-18 months and ADHD during childhood. Methods This case-control study included healthy children aged 6-18 years at data collection (April 2020), insured by Clalit-Health-Services, and aged 9-18 months between June 2004 and December 2013, when a blood-count was performed. The study group included children diagnosed with ADHD based on the medical documentation of at least two consecutive stimulant prescriptions. A control group without any stimulant prescriptions was matched in a ratio of 1-3:1, by year of birth, sex and cultural background. Any microcytic anemia was defined as Hb < 10.5 g/dl and MCV 60-75 fl. Moderate microcytic anemia as Hb 7-9.9 g/dl. We performed a conditional-logistic-regression analysis, adjusted by socioeconomic status (SES) and year of birth. Sensitivity analysis examined this association stratified by sex, cultural background, SES and age at data collection quintiles. Results Any microcytic anemia prevalence was lower in the ADHD group (n = 19,467) as compared to the controls (n = 39,004) (3.4 % and 4.0 %, respectively), adjusted-OR = 0.86 (95%CI: 0.78, 0.98). The prevalence of moderate microcytic anemia was similar (0.9 % vs. 1.0 %). Lower any microcytic anemia prevalence in the ADHD group was found in boys, secular-traditional Jews, and in the 4th quintile of age (12.1-13.5 years). Conclusions We found a small inverse association between microcytic anemia at 9-18-months and ADHD during childhood, thus rejecting our hypothesis that microcytic anemia at infancy is associated with a higher prevalence of ADHD. Further studies are warranted, to examine the effects of ID and brain iron concentration on the development of ADHD in childhood.

The Development and Content Validation of a Clinical Screening Scale to Identify Attention-Deficit Hyperactivity Disorder Cases Based on the Gender Perspective: An e-Delphi Study.

[PMID: 38998817 PMCID: PMC11241727 DOI: 10.3390/healthcare12131282] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2024] [Revised: 06/11/2024] [Accepted: 06/25/2024] [Indexed: 07/14/2024] Open
Abstract
BACKGROUND Although many studies analyse gender differences in the clinical expression of Attention-Deficit Hyperactivity Disorder (ADHD) and prevalence studies show that girls with ADHD are underdiagnosed, there are no instruments that are sensitive to the detection of girls with ADHD. OBJECTIVE The objective of this study is to develop a self-report early detection instrument for boys and girls with ADHD aged 7 to 16, which includes the gender perspective and is sensitive to the detection of girls with ADHD. METHODS The scale was developed and the items that comprised it were created from the thematic analysis of ADHD and its evaluation in children based on the diagnostic criteria of the DSM-5-TR. A modified e-Delphi method involving a three-round web survey was used to establish a consensus on the content of the scale. Ten experts were recruited to form a professional panel. The panel members were asked to assess the differential symptomatology of ADHD in boys and girls, the dimensions to be evaluated, and the importance of scale items to evaluate the content. RESULTS A consensus was reached regarding 13 total items distributed in three dimensions: inattention; hyperactivity/impulsivity; and, a third dimension, internalisation, which includes symptoms most present in the expression of ADHD in girls. CONCLUSIONS To the best of our knowledge, the development of this scale using the Delphi method is the first specific scale used for identifying ADHD that also addresses the gender perspective and the differential symptomatology between boys and girls. However, we must proceed to the analysis of psychometric properties, as the scale requires an exhaustive study of its reliability and validity. We can anticipate that this scale will provide relevant and reliable information that can be used for the identification of ADHD in both boys and girls.

Abstract
Despite the high prevalence of neurodevelopmental disorders, there is a notable gap in clinical studies exploring the impact of maternal diet during pregnancy on child neurodevelopment. This observational clinical study examined the association between pregnancy dietary patterns and neurodevelopmental disorders, as well as their symptoms, in a prospective cohort of 10-year-old children (n=508). Data-driven dietary patterns were derived from self-reported food frequency questionnaires. A Western dietary pattern in pregnancy (per SD change) was significantly associated with attention-deficit / hyperactivity disorder (ADHD) (OR 1.66 [1.21 - 2.27], p=0.002) and autism diagnosis (OR 2.22 [1.33 - 3.74], p=0.002) and associated symptoms (p<0.001). Findings for ADHD were validated in three large (n=59725, n=656, n=348), independent mother-child cohorts. Objective blood metabolome modelling at 24 weeks gestation identified 15 causally mediating metabolites which significantly improved ADHD prediction in external validation. Temporal analyses across five blood metabolome timepoints in two independent mother-child cohorts revealed that the association of Western dietary pattern metabolite scores with neurodevelopmental outcomes was consistently significant in early to mid-pregnancy, independent of later child timepoints. These findings underscore the importance of early intervention and provide robust evidence for targeted prenatal dietary interventions to prevent neurodevelopmental disorders in children.

Becker SP, Brown A, Langberg JM, Beebe DW. Later ("evening") circadian preference is associated with poorer executive, academic, and attentional functioning in adolescents with and without ADHD. J Child Psychol Psychiatry 2024. [PMID: 39031776 DOI: 10.1111/jcpp.14030] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 04/25/2024] [Indexed: 07/22/2024]
Abstract
BACKGROUND Adolescents vary considerably in their circadian phase preference; those with greater "eveningness" (also known as "night owls") have later bedtimes, wake times, and peak arousal compared to those with greater "morningness." Prior research suggests that (a) greater eveningness is associated with worse academic, executive, and attentional functioning; and (b) adolescents with attention-deficit/hyperactivity disorder (ADHD) tend to be high in eveningness and to have deficits in these school-related constructs. However, few studies have examined circadian preference alongside two potential confounds-sleep duration and sleep quality-as predictors of daytime functioning, or whether the strength of associations differs across adolescents with and without ADHD. METHODS Participants were 302 adolescents (Mage = 13.17 years; 44.7% female; 81.8% White); approximately half (52%) had ADHD. A multi-method, multi-informant design was used. Specifically, adolescents reported on their circadian preference, school night sleep duration, and sleep quality. Adolescents provided ratings of their academic motivation (intrinsic, extrinsic, and amotivation) and were administered standardized achievement tests in reading and math. Adolescents and parents completed ratings of daily life executive functioning (behavioral, emotion, and cognitive regulation), and they and teachers also provided ratings of ADHD inattentive symptoms. RESULTS Above and beyond sleep duration, sleep quality, and covariates (sex, family income, pubertal development, medication use), greater eveningness was uniquely associated with poorer academic, executive, and attentional functioning across most measures. Sleep quality was uniquely associated with a handful of outcomes, and sleep duration was not significantly uniquely associated with any outcome in the regression analyses. ADHD status did not moderate effects. CONCLUSIONS This study provides compelling evidence that poorer academic, executive, and attentional functioning are more closely associated with greater eveningness than with sleep duration or quality in adolescents. Findings suggest that targeting circadian preference may be important to reduce these problems in adolescents, especially in clinical samples such as ADHD for whom academic, executive, and attentional difficulties are exceptionally common.

Abstract
BACKGROUND Neurodevelopmental conditions frequently co-occur. The aim of this paper was to determine whether there is a cumulative association between (1) the number of neurodevelopmental conditions, specifically hyperkinetic disorder (hereafter referred to as attention deficit hyperactivity disorder), autism spectrum disorder (hereafter referred to as autism) and intellectual disability, and (2) behavioural and socio-emotional problems and the level of clinician-rated functioning for young males and females. METHODS In this cross-sectional study, diagnostic information, caregiver-rated behavioural and socio-emotional data (as conceptualised by the Strengths and Difficulties Questionnaire) and clinician-rated functioning scores (as conceptualised by the Children's Global Assessment Scale) were extracted from electronic patient records for 2768 young people aged 3-17 years (mean = 11.55, SD = 3.46). All data were extracted at baseline, that is, at the time the young person was diagnosed with attention deficit hyperactivity disorder, autism and/or an intellectual disability. Ordinal regression analyses tested associations between the number of neurodevelopmental conditions met (i.e. 1, 2 or 3) and behavioural and socio-emotional outcomes and functioning. RESULTS After controlling for age and biological sex, the number of neurodevelopmental conditions was associated with higher levels of inattention/hyperactivity and peer problems, lower levels of prosocial behaviour and poorer clinician-rated functioning. Although these findings were consistent for males, a cumulative association was not identified for females, except for clinician-rated functioning. CONCLUSIONS For young people, the presence of multiple neurodevelopmental conditions may have a cumulative impact across domains, but this may differ between males and females.

Abstract
BACKGROUND Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder that has manifestations of inattention, hyperactivity, and impulsivity. It affects every facet of a child's life, including one's own emotions, family and school life, and social interaction. The few available studies on ADHD conducted in Ethiopia focus on teachers' awareness and the prevalence of ADHD. None of these studies has taken into account parents of children who have ADHD. The present study, therefore, aimed to find out the challenges and coping mechanisms of parents who have children with ADHD. METHODS A phenomenological qualitative study was conducted to explore the experiences of parents who have children with ADHD. The study was carried out in Addis Ababa, the capital city of Ethiopia. Fourteen parents and two healthcare providers were involved in the study. Participants were selected using a purposive sampling technique. In-depth interviews were conducted with parents of children with ADHD (n = 8) and healthcare providers (n = 2). One focus group discussion (FGD), consisting of six members, was also conducted with parents. A topic guide for conducting the interviews and FGD was developed. Interviews and the FGD were audio-recorded. The data were transcribed verbatim, translated into English, and then analyzed using a thematic analysis approach. RESULTS With regard to challenges of parents of children with ADHD, three themes emerged: social challenges, economic challenges and psychological challenges. Stigma is found to be the most common challenge. Other challenges included worry about the child's future, lack of social support, strained relationships with others, impact on their job, and marital conflict. Concerning coping mechanisms, two themes emerged: Inward and outward means of coping. The inward means of coping included prayer and developing an optimistic mindset whereas the outward means were family support, healthcare providers' guidance, and social avoidance. CONCLUSIONS The study found that parents of children with ADHD experience several aspects of psychological, social, and economic challenges. Support from healthcare professionals, family members, and the community at large is found to be useful for parents to cope with these challenges. Future research should focus on evaluating interventions that would help parents with ADHD cope with the challenges they experience.

Abstract
BACKGROUND Population-based studies have observed sex biases in the diagnosis and treatment of attention-deficit hyperactivity disorder (ADHD). Females are less likely to be diagnosed or prescribed ADHD medication. This study uses national healthcare records, to investigate sex differences in diagnosis and clinical care in young people with ADHD, particularly regarding recognition and treatment of other mental health conditions. METHODS The cohort included individuals diagnosed with ADHD, born between 1989 and 2013 and living in Wales between 2000 and 2019. Routine primary and secondary healthcare record data were used to derive diagnoses of ADHD and other neurodevelopmental and mental health conditions, as well as ADHD and antidepressant medications. Demographic variables included ethnicity, socioeconomic deprivation and contact with social services. RESULTS There were 16,458 individuals diagnosed with ADHD (20.3% females, ages 3-30 years), with a male-to-female ratio of 3.9:1. Higher ratios (4.8:1) were seen in individuals diagnosed younger (<12 years), with the lowest ratio (1.9:1) in those diagnosed as adults (>18). Males were younger at first recorded ADHD diagnosis (mean = 10.9 vs. 12.6 years), more likely to be prescribed ADHD medication and younger at diagnosis of co-occurring neurodevelopmental conditions. In contrast, females were more likely to receive a diagnosis of anxiety, depression or another mental health condition and to be prescribed antidepressant medications, prior to ADHD diagnosis. These sex differences were largely stable across demographic groups. CONCLUSIONS This study adds to the evidence base that females with ADHD are experiencing later recognition and treatment of ADHD. The results indicate that this may be partly because of diagnostic overshadowing from other mental health conditions, such as anxiety and depression, or initial misdiagnosis. Further research and dissemination of findings to the public are needed to improve awareness, timely diagnosis and treatment of ADHD in females.

Abstract
PURPOSE The epidemiology of adult attention deficit hyperactivity disorder (ADHD) is not well explored in India. The present study aims to systematically review the literature on the prevalence of adult ADHD in India and also estimate the prevalence and sociodemographic correlates of adult ADHD among the young adults in Delhi-NCR. METHODS For the systematic review, 494 articles were identified of which 10 were included in the review. Simultaneously, a cross-sectional study was conducted involving 1665 adults (18-25 years; mean age 19.92) of both sexes (69.1% females) from different colleges in Delhi-NCR, India. Data was collected using structured interviews and standardized diagnostic tool ASRS V1.1 was used for screening of ADHD. RESULT The systematic review revealed a high prevalence of adult ADHD ranging from 5.48 to 25.7% among general and specific populations of India. Further, in the cross-sectional study, 14% of participants were screened positive for ADHD. While factors like South Indian origin and higher maternal education were associated with an increased risk of adult ADHD, low socioeconomic status was found to be protective. CONCLUSION Considering the high prevalence of adult ADHD in India, there is an urgent need to increase awareness regarding adult ADHD and identify vulnerable populations to facilitate informed interventions.

Abstract
OBJECTIVE To characterize provider types delivering outpatient care overall and through telehealth to U.S. adults with ADHD. METHOD Using employer-sponsored insurance (ESI) and Medicaid claims, we identified enrollees aged 18 to 64 years who received outpatient care for ADHD in 2021. Billing provider codes were used to tabulate the percentage of enrollees receiving ADHD care from 10 provider types overall and through telehealth. RESULTS Family practice physicians, psychiatrists, and nurse practitioners/psychiatric nurses were the most common providers for adults with ESI, although the distribution of provider types varied across states. Lower percentages of adults with Medicaid received ADHD care from physicians. Approximately half of adults receiving outpatient ADHD care received ADHD care by telehealth. CONCLUSION Results may inform the development of clinical guidelines for adult ADHD and identify audiences for guideline dissemination and education planning.

Abstract
Methylphenidate (MPH), a first-line treatment for attention-deficit hyperactivity disorder (ADHD) management, has been the focus of debate for decades regarding its effect on growth. The aim of this PRISMA meta-analysis was to determine the effect of MPH on height in children/adolescents with ADHD and its predictive factors based on literature reports. Available full-text articles were systematically reviewed to identify clinical studies of pediatric ADHD patients with height Z-score (HZS) data for monotherapy MPH-treated and non-treated groups. We estimated standardized mean differences (SMDs) of HZS or its changes from baseline (ΔHZS) between groups, then identified associated factors through subgroup analyses and meta-regression. For before-after treatment studies, the paired standard errors of ΔHZS were re-estimated to demonstrate in the forest plot. Risk of bias was analyzed using the Newcastle-Ottawa Scale. Among the 29 eligible studies, 26 reported ΔHZS with self-control groups, and ΔHZS or absolute HZS were compared to other external controls in 11 studies. A significant reduction was observed between post-MHP and pre-MPH use, with high heterogeneity (SMD = - 0.40; 95% confidence interval = [ - 0.54, - 0.27]; I2 = 91%). The study region, ADHD subtype, and stimulant-naïve status of patients at baseline may modify the effect on HZS. Because of the high clinical heterogeneity in observational studies, clinicians should consider the negative effect of MPH on height in ADHD patients by determining whether patients fulfill appropriate high-risk criteria. Further well-designed longitudinal studies are required to better quantify this effect, especially with prolonged treatment.

Abstract
Underrepresentation of socioeconomically, culturally, and/or linguistically diverse (SCLD) children with neurodevelopmental disorders (NDD) and their families has become a focal point for researchers. This systematic review aimed to identify researchers' strategies for recruiting and retaining SCLD families of children with NDD, published between 1993 and 2018. One hundred twenty-six articles were included, and study samples were categorized as "High SCLD" and "Low SCLD". Chi-square tests of independence were used to determine associations between sample composition (i.e., High/Low SCLD sample) and study characteristics reported. Significant associations were found between sample composition and studies that explicitly stated intention to recruit SCLD families, χ2(1) = 12.70, p < .001, Phi = 0.38 (moderate); and for studies that reported the following participant characteristics: language, χ2(1) = 29.58, p < .001, Phi = 0.48 (moderate-to-large); and race/ethnicity + SES + language, χ2(1) = 19.26, p <. 001, Phi = 0.39 (moderate). However, associations were not found between recruitment and retention approaches and whether studies included High SCLD or Low SCLD samples. Further study of NDD researchers' recruitment and retention approaches that successfully include SCLD families is needed.

Abstract
BACKGROUND Early-life exposure to phthalates alters behaviors in animals. However, epidemiological evidence on childhood phthalate exposure and attention-deficit/hyperactivity disorder (ADHD) behaviors is limited. METHODS This study included 243 children from the ReCHARGE (Revisiting Childhood Autism Risks from Genetics and Environment) study, who were previously classified as having autism spectrum disorder (ASD), developmental delay, other early concerns, and typical development in the CHARGE case-control study. Twenty phthalate metabolites were measured in spot urine samples collected from children aged 2-5 years. Parents reported on children's ADHD symptoms at ages 8-18 years using Conners-3 Parent Rating Scale. Covariate-adjusted negative binomial generalized linear models were used to investigate associations between individual phthalate metabolite concentrations and raw scores. Weighted quantile sum (WQS) regression with repeated holdout validation was used to examine mixture effects of phthalate metabolites on behavioral scores. Effect modification by child sex was evaluated. RESULTS Among 12 phthalate metabolites detected in >75% of the samples, higher mono-2-heptyl phthalate (MHPP) was associated with higher scores on Inattentive (β per doubling = 0.05, 95% confidence interval [CI]: 0.02, 0.08) and Hyperactive/Impulsive scales (β = 0.04, 95% CI: 0.00, 0.07), especially among children with ASD. Higher mono-carboxy isooctyl phthalate (MCiOP) was associated with higher Hyperactivity/Impulsivity scores (β = 0.07, 95% CI: -0.01, 0.15), especially among typically developing children. The associations of the molar sum of high molecular weight (HMW) phthalate metabolites and a phthalate metabolite mixture with Hyperactivity/Impulsivity scores were modified by sex, showing more pronounced adverse associations among females. CONCLUSION Exposure to phthalates during early childhood may impact ADHD behaviors in middle childhood and adolescence, particularly among females. Although our findings may not be broadly generalizable due to the diverse diagnostic profiles within our study population, our robust findings on sex-specific associations warrant further investigations.

Selenoprotein T, a potential treatment of attention-deficit/hyperactivity disorder and comorbid pain in neonatal 6-OHDA lesioned mice. Exp Mol Pathol 2024; 137:104905. [PMID: 38797131 DOI: 10.1016/j.yexmp.2024.104905] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2023] [Revised: 05/21/2024] [Accepted: 05/22/2024] [Indexed: 05/29/2024]
Abstract
pathological pain and Attention-deficit/hyperactivity disorder (ADHD) are two complex multifactorial syndromes. The comorbidity of ADHD and altered pain perception is well documented in children, adolescents, and adults. According to pathophysiological investigations, the dopaminergic system's dysfunction provides a common basis for ADHD and comorbid pain. Growing evidence suggests that oxidative stress may be crucial in both pathologies. Recent studies revealed that a small peptide encompassing the redox-active site of selenoprotein T (PSELT), protects dopaminergic neurons and fibers as well as lesioned nerves in animal models. The current study aims to examine the effects of PSELT treatment on ADHD-like symptoms and pain sensitivity, as well as the role of catecholaminergic systems in these effects. Our results demonstrated that intranasal administration of PSELT reduced the hyperactivity in the open field, decreased the impulsivity displayed by 6-OHDA-lesioned male mice in the 5-choice serial reaction time task test and improved attentional performance. In addition, PSELT treatment significantly increased the nociception threshold in both normal and inflammatory conditions. Furthermore, anti-hyperalgesic activity was antagonized with sulpiride pre-treatment, but not by phentolamine, or propranolol pre-treatments. The present study suggests that PSELT reduces the severity of ADHD symptoms in mice and possesses potent antinociceptive effects which could be related to the involvement of D2/D3 dopaminergic receptors.

Abstract
BACKGROUND To fulfil the diagnostic criteria of Attention Deficit Hyperactivity Disorder in the Fifth Edition of Diagnostic and Statistical Manual of Mental Disorders (DSM-5), symptoms should be observed in two or more settings. This implies that diagnostic procedures require observations reported from informants in different settings, such as teachers in school and caregivers at home. This study examined parent-teacher agreement in reporting hyperactivity/inattention and its relationship with child's, parent's, and family's characteristics. METHOD We used data from the 2004 United Kingdom Mental Health of Children and Young People survey, including 7977 children aged 4-17, to investigate cross-informant agreement between parents and teachers on the hyperactivity-inattention subscale of the Strengths and Difficulties Questionnaire. The characteristics of different patterns of informant agreement were assessed using multinomial logistic regression. RESULTS Cross-informant agreement of parent and teacher was low (weighted kappa = .34, 95% C.I.: .31, .37). Some characteristics, such as male child and parental emotional distress, were associated with higher likelihood of parent-teacher discrepancy. CONCLUSION We found low informant agreement in the hyperactive/inattention subscale, as hypothesised and consistent with previous studies. The current study has found several factors that predict discrepancy, which were partly consistent with previous research. Possible explanation, implications, and further research on parent-teacher informant discrepancy in reporting hyperactivity/inattention were discussed.

Abstract
OBJECTIVE To summarize and analyze recent articles investigating self-esteem in adults with ADHD, focusing on the impact of demographic and clinical characteristics, and methodological issues. METHOD Following PRISMA guidelines, a systematic search for literature published between 2010 and 2022 was conducted in the Web of Science, Ovid, Pubmed, and EBSCO databases. RESULTS Eleven studies met inclusion criteria. Five of the six studies including healthy controls reported lower self-esteem in participants with ADHD. ADHD symptoms correlated negatively with self-esteem. Gender differences were not observed. Self-esteem mediated several outcomes associated with ADHD. There was a lack of studies that examined potential mechanisms behind the reduced self-esteem, and studies controlling for confounding variables. CONCLUSION A robust association between ADHD and low self-esteem in adults emerged, but the lack of control of confounding variables is critical to consider when interpreting the findings. Longitudinal studies addressing the limitations of the current studies are needed.

Abstract
OBJECTIVE To systematically review the prevalence of Attention Deficit Hyperactivity Disorder (ADHD) among Black children and adolescents compared to White, Latino and Asian children and adolescents. METHOD Peer-reviewed articles were identified in seven databases and included if they reported prevalence of ADHD among Black children and adolescents living in a minority context and compared rates to at least one of White, Latino or Asian samples. A total of 7050 articles were retrieved and 155 articles were subjected to full evaluation. Twenty-three studies representing 26 independent samples were included. RESULTS The pooled sample size was n = 218,445 (k = 26), n = 835,505 (k = 25), n = 493,417 (k = 24), and n = 66,413 (k = 7) of Black, White, Latino, and Asian participants, respectively. Pooled prevalence rate of ADHD was 15.9% (95%CI 11.6% - 20.7%) among Black children and adolescents, 16.6% (95%CI 11.6% - 22.2%) among Whites, 10.1% (95%CI 6.9% - 13.8%) among Latinos and 12.4% (95%CI 1.4% - 31.8%) among Asians. There was no significant difference in prevalence between ethnic groups, whereas both Black and White children and adolescents had marginally statistically significant higher prevalence than Asians. The results of a meta-regression analysis showed no moderating effects of the type of sample and the year of publication of studies. A significant publication bias was observed, suggesting that other moderators were not identified in the present systematic review. CONCLUSION In contrast to the assertion in the DSM-5 that clinical identification among Black children and adolescents is lower than among White children and adolescents, the present meta-analysis suggests similar rates of ADHD among these two groups. The importance of considering cultural appropriateness of assessment tools and processes is emphasized.

Abstract
Background To determine the association between neurological soft signs, executive functions, and serum brain-derived neurotrophic factor (BDNF) levels in children with attention-deficit hyperactivity disorder (ADHD). Methods Serum BDNF levels were measured in 87 drug-naive boys with ADHD, aged 7-12 years. The Revised Physical and Neurological Examination for Subtle Signs for neurological soft signs, Stroop Color-Word Test for attention functions, and Judgment of Line Orientation Test (JLOT) for visuospatial abilities were performed. Results Age correlated negatively with dysrhythmia, total time, and total overflow in timed movements, Stroop Color-Word Time (SCWT), and serum BDNF levels. The JLOT significantly negatively correlated with Total Gaits and Stations (P1) and Total Time in Timed Movements (adjusted R 2 = 0.247). In addition, SCWT maintained a significant correlation with Total Overflow in Timed Movements (adjusted R 2 = 0.206). There was no correlation between serum BDNF levels and NSS. Conclusion The association between NSS, visuospatial abilities, and selective attention may express a maturational delay in ADHD pathophysiology. Moreover, BDNF may play a role in this maturational delay. Future studies should investigate the contribution of BDNF to neuronal maturation in ADHD.

Abstract
This study investigates the capacity of pre/perinatal factors to predict attention-deficit/hyperactivity disorder (ADHD) symptoms in childhood. It also explores whether predictive accuracy of a pre/perinatal model varies for different groups in the population. We used the ABCD (Adolescent Brain Cognitive Development) cohort from the United States (N = 9975). Pre/perinatal information and the Child Behavior Checklist were reported by the parent when the child was aged 9-10. Forty variables which are generally known by birth were input as potential predictors including maternal substance-use, obstetric complications and child demographics. Elastic net regression with 5-fold validation was performed, and subsequently stratified by sex, race/ethnicity, household income and parental psychopathology. Seventeen pre/perinatal variables were identified as robust predictors of ADHD symptoms in this cohort. The model explained just 8.13% of the variance in ADHD symptoms on average (95% CI = 5.6%-11.5%). Predictive accuracy of the model varied significantly by subgroup, particularly across income groups, and several pre/perinatal factors appeared to be sex-specific. Results suggest we may be able to predict childhood ADHD symptoms with modest accuracy from birth. This study needs to be replicated using prospectively measured pre/perinatal data.

Abstract
Many studies focus on problematic peer functioning in attention deficit/hyperactivity disorder (ADHD) but loneliness has been studied less. This paper examined (1) The loneliness level differences between young people (below 25 years old) with ADHD and those without ADHD, and (2) The association between loneliness and mental health difficulties in young people with ADHD. Six electronic databases were searched and 20 studies were included. A random effects meta-analysis was carried out in RStudio using the metafor package for the first question, while a narrative synthesis summarized the findings for the second question. The meta-analysis (n = 15) found that young people with ADHD reported significantly higher loneliness than those without ADHD, with a small-to-medium weighted pool effect (Hedges' g = 0.41) and high heterogeneity (I2 = 75.1%). For the second question (n = 8), associations between loneliness and mental health difficulties in ADHD was found (r = 0.05-0.68). Targeted research and interventions on loneliness in young people with ADHD is needed.

Abstract
In the past two decades, the traditional nosology of attention-deficit/hyperactivity disorder (ADHD) has been criticized for having insufficient discriminant validity. In line with current trends, in the present study, we combined a data-driven approach with the advantages of virtual reality aiming to identify novel behavioral profiles of ADHD based on ecological and performance-based measures of inattention, impulsivity, and hyperactivity. One hundred and ten Spanish-speaking participants (6-16 years) with ADHD (medication-naïve, n = 57) and typically developing participants (n = 53) completed AULA, a continuous performance test embedded in virtual reality. We performed hybrid hierarchical k-means clustering methods over the whole sample on the normalized t-scores of AULA main indices. A five-cluster structure was the most optimal solution. We did not replicate ADHD subtypes. Instead, we identified two clusters sharing clinical scores on attention indices, susceptibility to distraction, and head motor activity, but with opposing scores on mean reaction time and commission errors; two clusters with good performance; and one cluster with average scores but increased response variability and slow RT. DSM-5 subtypes cut across cluster profiles. Our results suggest that latency of response and response inhibition could serve to distinguish among ADHD subpopulations and guide neuropsychological interventions. Motor activity, in contrast, seems to be a common feature among ADHD subgroups. This study highlights the poor feasibility of categorical systems to parse ADHD heterogeneity and the added value of data-driven approaches and VR-based assessments to obtain an accurate characterization of cognitive functioning in individuals with and without ADHD.

Abstract
OBJECTIVE To estimate prevalence and incidence rates over time in children and youth with attention deficit/hyperactivity disorder from the validation of population-based administrative data algorithms using family physicians' electronic medical records as a reference standard. METHODS A retrospective cohort study was conducted in Ontario, Canada to identify attention deficit/hyperactivity disorder among children and youth aged 1-24 years in health administrative data derived from case-finding algorithms using family physicians' electronic medical records. Multiple administrative data algorithms identifying attention deficit/hyperactivity disorder cases were developed and tested from physician-diagnosis of attention deficit/hyperactivity disorder in the electronic medical record to determine their diagnostic accuracy. We calculated algorithm performance using sensitivity, specificity, and predictive values. The most optimal algorithm was used to estimate prevalence and incidence rates of attention deficit/hyperactivity disorder from 2014 to 2021 in Ontario. RESULTS The optimal performing algorithm was "2 physician visits for attention deficit/hyperactivity disorder in 1 year or 1 attention deficit/hyperactivity disorder-specific prescription" with sensitivity: 83.2% (95% confidence interval [CI], 81.8% to 84.5%), specificity: 98.6% (95% CI, 98.5% to 98.7%), positive predictive value: 78.6% (95% CI, 77.1% to 80.0%) and negative predictive value: 98.9% (95% CI, 98.8% to 99.0%). From 2014, prevalence rates for attention deficit/hyperactivity disorder increased from 5.29 to 7.48 per 100 population in 2021 (N = 281,785). Males had higher prevalence rates (7.49 to 9.59 per 100 population, 1.3-fold increase) than females (2.96-5.26 per 100 population, 1.8-fold increase) from 2014 to 2021. Incidence rates increased from 2014 (0.53 per 100 population) until 2018, decreased in 2020 then rose steeply in 2021 (0.89 per 100 population, N = 34,013). Males also had higher incidence rates than females from 2014 to 2020 with females surpassing males in 2021 (0.70-0.81 per 100 male population,1.2-fold increase versus 0.36-0.97 per 100 female population, 2.7-fold increase). CONCLUSIONS Attention deficit/hyperactivity disorder is increasing in prevalence. We developed an administrative data algorithm that can reliably identify children and youth with attention deficit/hyperactivity disorder with good diagnostic accuracy.

Abstract
OBJECTIVE The aim of this study was to investigate the prevalence and psychiatric correlates of symptomatic ADHD in a large metropolitan area of a middle-income country. METHODS An in-person household survey with randomly selected 2,297 adults aged 19 to 60 from Rio de Janeiro, Brazil, assessed by trained lay interviewers. The Adult Self-Rating Scale Screener (ASRS-6) was used. Chi-square and logistic regression were conducted. RESULTS ADHD prevalence was 4.59 (95% CI [3.56, 5.44]). Those with ADHD were younger and more often unemployed; they displayed more psychiatric symptoms (depression, anxiety, and alcohol abuse) and a history of bullying and sexual abuse. They also had worse physical health indicators. Findings remained significant when controlling for socioeconomic variables. CONCLUSION Adults with symptomatic ADHD from a large metropolitan area in Brazil show a pattern of findings consistent with what has been observed in higher-income countries.

Eur Child Adolesc Psychiatry 2024:10.1007/s00787-024-02426-6.

Abstract
The link between inflammatory disorders, such as asthma, and attention deficit hyperactivity disorder (ADHD) is attracting increasing attention but few studies have examined cross-generational associations. We sought to examine associations of maternal asthma and asthma exacerbation during pregnancy, as well as paternal asthma, with the risk of ADHD in children. This population-based cohort study used data from the Taiwan National Health Insurance Research Database from 2004 to 2017. Cox regression models compared the risk of ADHD in children of parents with and without asthma, adjusting for parental sociodemographic, physical, and mental health conditions, as well as the child's birth weight, and number of births. A sibling control approach was employed to compensate for unmeasured confounders of asthma exacerbation during pregnancy. In the fully adjusted models, maternal and paternal asthma were both significantly associated with an increased risk of ADHD in offspring, with hazard ratios (HRs) of 1.36 (1.31-1.40) and 1.10 (1.05-1.14), respectively. Acute asthma exacerbation during pregnancy was not associated with the risk of further offspring ADHD (adjusted HR 1.00, 95% CI: 0.75-1.34). Both maternal and paternal asthma are associated with an increased risk of ADHD in offspring. The risk was higher from maternal asthma. However, no such association was found with maternal asthma exacerbation during pregnancy of sibling comparison.

Abstract
ADHD and bipolar disorder (BP) commonly coexist, and both share key symptoms, depending on affective state and emotional dysregulation. The overlap poses diagnostic challenges and may lead to underdiagnoses. Comorbid cases exhibit worsened symptom burden, increased psychiatric morbidity, admissions, and suicide attempts. Treating BP before ADHD is recommended. Stimulant use combined with mood stabilisers may be effective and relatively safe; however, this review finds that well-designed randomised controlled studies in the area is warranted.

Abstract
OBJECTIVES Physical activity (PA) is recommended as part of the management of narcolepsy type 1 (NT1). This study aimed at 1) characterizing PA in children and adolescents treated for NT1 using objective and subjective measurements, 2) evaluating how PA is associated with NT1 symptoms and comorbidities, and 3) evaluating the effects of an Adapted Physical Activity (APA) program on PA and clinical characteristics. PATIENTS/METHODS Patients with NT1 from the National Reference Center of Narcolepsy (Lyon, France) were consecutively included in an APA intervention protocol. Narcolepsy symptoms and comorbidities were collected using standardized questionnaires and sustained attention was evaluated using the Bron-Lyon Attention Stability Test before and after the four-week APA intervention. PA was measured objectively using actigraphy throughout the study. RESULTS Twenty-seven NT1 patients were included (median age 14.7 years [8.3-18.4], cataplexy 88.9%, obesity 37.0%). At baseline, 52.4% of the patients had satisfactory PA levels according to international recommendations. Patients with leisure-time PA (LTPA) showed higher quality of life than patients without. 45% of the patients increased PA during the intervention compared to baseline. These responsive patients had more depressive feelings and tended to have lower objective PA than non-responsive patients at baseline. No significant correlation was found between PA levels before and during the intervention and other clinical data. CONCLUSIONS Most children with NT1 showed satisfying PA levels despite their daytime sleepiness. LTPA engagement was associated with higher quality of life. An APA intervention could be effective in children with narcolepsy, especially for those with depressive feelings.

Abstract
The role of neurogenesis in neurodevelopmental disorders (NDDs) merits much attention. The complex process by which stem cells produce daughter cells that in turn differentiate into neurons, migrate various distances, and form synaptic connections that are then refined by neuronal activity or experience is integral to the development of the nervous system. Given the continued postnatal neurogenesis that occurs in the mammalian olfactory system, it provides an ideal model for understanding how disruptions in distinct stages of neurogenesis contribute to the pathophysiology of various NDDs. This review summarizes and discusses what is currently known about the disruption of neurogenesis within the olfactory system as it pertains to attention-deficit/hyperactivity disorder, autism spectrum disorder, Down syndrome, Fragile X syndrome, and Rett syndrome. Studies included in this review used either human subjects, mouse models, or Drosophila models, and lay a compelling foundation for continued investigation of NDDs by utilizing the olfactory system.

Abstract
ADHD is less likely to be diagnosed in females than males, especially in childhood. Females also typically receive the diagnosis later than males and are less likely to be prescribed ADHD medication. Understanding why these sex differences in clinical care and treatment for ADHD occur is key to improving timely diagnosis in people affected by ADHD. This Personal View is a conceptual review synthesising literature on this topic. This publication considers potential biological explanations (eg, genetic factors), influence of diagnostic practices (eg, criteria suitability, diagnostic overshadowing, and sex-specific diagnostic thresholds), and sociocultural explanations (eg, sex differences in presentation and compensatory behaviours), for the observed sex differences in ADHD clinical practice. This Personal View also outlines future research directions for improving understanding of sex differences in recognition and diagnosis of ADHD.

Abstract
OBJECTIVE Internalizing psychopathology commonly co-occurs with attention-deficit/hyperactivity disorder (ADHD). Attention concerns are present in both ADHD and internalizing disorders, yet the neuropsychological functioning of those with comorbid ADHD and internalizing psychopathology is underexamined. METHOD This study compared Conners' Continuous Performance Test-Third Edition (CPT-3) profiles across ADHD (n = 141), internalizing psychopathology (n = 78), and comorbid (ADHD/internalizing psychopathology; n = 240) groups. RESULTS Compared to the internalizing psychopathology group, the comorbid group had higher mean T-scores on CPT-3 indices indicative of inattentiveness and impulsivity and more clinically elevated T-scores (T>60) on indices measuring inattentiveness and impaired sustained attention. Patients in the comorbid group were also more likely to have abnormal overall CPT-3 profiles (>2 elevated T-scores) than the ADHD and psychopathology only groups. CONCLUSION Patients with comorbid ADHD/internalizing psychopathology may evidence a more impaired attentional performance on the CPT-3, which could aid in more tailored treatment planning.

Abstract
AIM To investigate the prevalence of attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) in a population-based birth cohort and correlate the findings with prenatal and perinatal factors. We hypothesized that children born preterm, having experienced preeclampsia or maternal overweight, would have an increased risk of ADHD or ASD. METHOD A Swedish cohort of 2666 children (1350 males, 1316 females) has been followed from birth with parental and perinatal data. The National Board of Health and Welfare's registries were used to collect data regarding perinatal status and assigned diagnoses at the age of 12 years. RESULTS The prevalence of ADHD and ASD was 7.6% and 1.1% respectively. Maternal obesity early in pregnancy resulted in a three-fold increased risk of ADHD in the child. Similarly, paternal obesity resulted in a two-fold increased risk. The association was significant also when adjusted for sex, preterm birth, smoking, and lower educational level. The prevalence of ASD was too low for statistically relevant risk factor analyses. INTERPRETATION Our results corroborate earlier findings regarding prevalence and sex ratio for both ADHD and ASD. Maternal body mass index and preterm birth were correlated with an ADHD diagnosis at the age of 12 years.

Abstract
OBJECTIVES This study aims to assess whether the presence of Internet Gaming Disorder (IGD) is associated with disease severity, Attention Deficit Hyperactivity Disorder(ADHD) presentation, emotional problems, behavioral problems, and CPT profile in patients with ADHD. METHOD Forty children with IGD and sixty-four patients without IGD were included in the study, all of whom had a diagnosis of ADHD. Comorbid psychiatric disorders were determined using The Kiddie Schedule for Affective Disorders and Schizophrenia (K-SADS). Conners's Parent Rating Scale-Revised Short form (CPRS-RS), The Strengths and Difficulties Questionnaire (SDQ), Internet Gaming Disorder Questionnaire (IGD-20), and MOXO Continuous Performance Test (MOXO d-CPT) were performed on the children, and Clinical Global Impression (CGI), Children's Global Assessment Scale (CGAS), comorbidities and ADHD presentations were evaluated. RESULTS The IGD group was found to have the combined presentation of ADHD more commonly, and their CGI, CGAS, SDQ behavior problems subscale, cognitive problems, attention problems, and ADHD index in the CPRS-RS questionnaire were found to be higher (p < 0.05). No differences were found in attention, timing, impulsiveness, and hyperactivity scores in CPT between groups (p > 0.05). CONCLUSION Our study has shown that children with both ADHD and IGD had more severe symptoms, more behavioral problems, and differences regarding the prevalence of the ADHD presentations when compared to children having ADHD without IGD. Longitudinal studies with higher sample sizes are required to investigate this possible connection in the context of a cause-effect relationship and draw a conclusion.

Abstract
Temperament, parenting, and executive functioning (EF) are individual and contextual factors that have been identified to play a role in the development of Attention-Deficit/Hyperactivity Disorder (ADHD) symptoms. Specifically, exuberant temperament in toddlerhood has been associated with both adaptive and maladaptive outcomes, including ADHD symptoms. Therefore, it is important to understand factors that predict which exuberant children experience increased ADHD symptoms and the specific mechanisms through which early exuberant temperament impacts later ADHD symptoms. Using a multi-method, prospective longitudinal design, this study examined a moderated mediation model wherein the interactive effects of observed exuberance and parenting at age 3 predicted the development of parent-reported ADHD symptoms from childhood through adolescence (age 5, 7, 9, 12, and 15) via child EF (i.e., inhibitory control) at age 4. Parent-child dyads (n = 291) from a longitudinal study on child temperament were included. A piecewise model of ADHD symptom growth demonstrated stability in ADHD symptoms from age 5-9 and a decrease from age 9-15. Results support a moderated mediation model wherein an increase in ADHD symptoms throughout childhood was predicted from early childhood exuberant temperament by way of EF, but only for children whose parents displayed less directive parenting. Findings suggest identifiable early markers of risk, including temperament, parenting, and EF- pointing to possible targets for early intervention/prevention.

Abstract
Purpose/aim of the study: The study aimed to highlight the possible role of ciliary neurotrophic factor (CNTF) in the pathophysiology of attention deficit hyperactivity disorder (ADHD) and determine whether CNTF can be used as a biomarker for ADHD.Materials and methods: Patients with a diagnosis of ADHD and neurotypical subjects aged 6-12 years were recruited prospectively. The study applied Conners' Teacher Rating Scale (CTRS) to determine the patients' ADHD predominance and severity. Serum CNTF levels were measured with an enzyme-linked immunosorbent assay (ELISA) kit.Results: A total of 43 ADHD patients and 33 healthy controls were included in the study. A significant difference was found between the serum CNTF levels of the ADHD patients (22.17 pg/ml) and the controls (22.80 pg/ml). Correlations between the CNTF levels and CTRS scores were not significant.Conclusions: The study identified an alteration of serum CNTF levels in ADHD patients and thus asserted a link between CNTF and ADHD pathophysiology; children with ADHD had significantly lower serum CNTF levels compared to the neurotypical controls. Further research is needed to understand the mechanisms of CNTF.
