Abstract
OBJECTIVES To evaluate the prevalence and degree of any neurodevelopmental abnormalities in children with familial hypocalciuric hypercalcemia type 3 (FHH3). STUDY DESIGN A formal neurodevelopmental assessment was performed in children diagnosed with FHH3. The Vineland Adaptive Behavior Scales, which is a standardized parent report assessment tool for adaptive behavior, was used to assess communication, social skills, and motor function and to generate a composite score. RESULTS Six patients were diagnosed with hypercalcemia between 0.1 and 8 years of age. All had neurodevelopmental abnormalities in childhood consisting of either global developmental delay, motor delay, expressive speech disturbances, learning difficulties, hyperactivity, or autism spectrum disorder. Four out of the 6 probands had a composite Vineland Adaptive Behavior Scales SDS of < -2.0, indicating adaptive malfunctioning. Significant deficits were observed in the domains of communication (mean SDS: -2.0, P < .01), social skills (mean SDS: -1.3, P < .05), and motor skills (mean SDS: 2.6, P < .05). Individuals were equally affected across domains, with no clear genotype-phenotype correlation. All family members affected with FHH3 also described evidence of neurodevelopmental dysfunction, including mild-to-moderate learning difficulties, dyslexia, and hyperactivity. CONCLUSION Neurodevelopmental abnormalities appear to be a highly penetrant and common feature of FHH3, and early detection is warranted to provide appropriate educational support. This case series also supports consideration of serum calcium measurement as part of the diagnostic work-up in any child presenting with unexplained neurodevelopmental abnormalities.

Abstract
Although bivariate associations between attention-deficit/hyperactivity disorder (ADHD) and eating disorders in adolescent girls and boys have been previously identified, the mechanistic link underlying the symptom-level associations remains unclear. We evaluated shared genetic and environmental influences on ADHD symptoms and disordered eating in 819 female and 756 male twins from the Swedish TCHAD cohort using bivariate models. Common additive genetic and unique environmental effects accounted for majority of ADHD and disordered eating associations in a differential manner. For girls, the strongest genetic correlation was observed for cognitive/inattention problems-bulimia (0.54), with genetic factors accounting for 67% of the phenotypic correlation. For boys, the strongest genetic correlations were observed for conduct problems-bulimia and hyperactivity-bulimia (~ 0.54), accounting for 83% and 95% of the phenotypic correlation, respectively. As per our findings, the risk of comorbidity and shared genetics highlights the need for preventative measures and specialized treatment for ADHD and disordered eating in both sexes.

Abstract
BACKGROUND Attention deficit hyperactivity disorder (ADHD) symptoms may persist into adulthood and are likely to cause great problems in young adults. To date, few studies have explored the characteristics of patients diagnosed with ADHD that might influence the utilization of adult mental health services (AMHS). We aimed to examine and identify predictive symptoms of AMHS. METHODS We analysed data from 114 participants diagnosed with ADHD from a cohort of adolescents recruited at the age of 12-17 years, who, at the time of data analysis, were over 18 years old. RESULTS Among AMHS users, hyperactivity/impulsivity measures were significantly more severe (t = 2.668, df = 112, p < .001), ADHD combined subtype diagnosis (χ2 = 4.66, df = 1, p = .031) was more frequent and dysregulation profile in the SDQ-P was also significantly higher (t = -2.497, df = 109, p = .014). However, the dysregulation profile did not remain statistically significant after controlling for type of AMHS contact. CONCLUSIONS Our findings suggest that adolescents with ADHD are more likely continue their care under AMHS if they present more severe symptoms of hyperactivity/impulsivity and emotional dysregulation. The better characterization of the patient profile will help clinicians to early identify groups at-risk and to tailor interventions and prevention strategies.

Abstract
Background: Non-stimulant guanfacine is a common second-line medication for attention-deficit hyperactivity disorder (ADHD). Numerous randomized controlled trials (RCTs) have explored the efficacy of guanfacine in ADHD treatment. This meta-analysis combined data from selected RCTs to analyze the efficacy and safety of guanfacine in treating ADHD. Methods: RCTs were identified from published sources through searches in PubMed, Cochrane Library, Web of Science, and Embase (up to February 2022), defining the Clinical Global Impression of Improvement (CGI-I) treatment response score of ≤2 as the primary outcome. Subgroup analysis was performed with a bound treatment duration of 10 weeks. Safety was defined by treatment-emergent adverse events (TEAEs). Results: Twelve out of 332 studies with 2653 participants were included. All studies compared guanfacine with placebos. Guanfacine was significantly more effective in treating ADHD (Risk Ratio [RR] 1.78, 95% CI: 1.59-2.01). In the <10 weeks subgroup, the efficacy in the guanfacine group compared with the placebo group was 58.5% versus 29.4%, respectively (RR 1.97, 95% CI: 1.71-2.26). In the >10 weeks subgroup, the efficacy in the guanfacine group compared with the placebo group was 63.6% versus 39.7%, respectively (RR 1.57, 95% CI: 1.37-1.79). Both subgroups lacked heterogeneity (I2 = 0), and a funnel plot showed a low publication bias risk. Around 80% of participants in the guanfacine group experienced at least one TEAE, compared with 66.5% in the placebo group (RR 1.23, 95% CI: 1.14-1.32), with low heterogeneity (I2 = 46, p = 0.05). The most common TEAEs in the guanfacine group were somnolence (38.6%), headaches (20.5%), and fatigue (15.2%). Conclusions: Guanfacine is safe and effective for treating ADHD, with no serious adverse events. Guanfacine should be considered as an effective treatment option where effectiveness or tolerability of the central nervous system stimulant is of concern. There is stronger evidence of efficacy for children; more clinical studies are needed for adults.

Urinary concentrations of bisphenols and parabens and their association with attention, hyperactivity and impulsivity at adolescence. Neurotoxicology 2023; 95:66-74. [PMID: 36649891 DOI: 10.1016/j.neuro.2023.01.006] [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: 08/03/2022] [Revised: 01/11/2023] [Accepted: 01/12/2023] [Indexed: 01/15/2023]
Abstract
BACKGROUND Neurobehavioural disorder diagnoses have been increasing over the last decades, leading to heightened interest in the aetiological factors involved. Endocrine disrupting chemicals, such as parabens and bisphenols, have been suggested as one of those factors. It is unknown whether exposure during adolescence may affect neurobehavioural development. OBJECTIVE To determine whether urinary concentrations of parabens and bisphenols are associated with attention and concentration in adolescents, in general and sex-specific. METHODS We invited 188 adolescents (13-15 years old) for the follow-up birth cohort-study. Concentrations of five parabens and three bisphenols (BPA; BPF; BPS) were measured in morning urine after overnight fasting, using a validated LC-MS/MS method. Attention and concentration were assessed at the clinic with subtests of the Test of Everyday Attention in Children and the Dutch Attention Deficit Hyperactivity Disorder questionnaire (AVL), the latter being filled in by parents. Linear regression analyses were performed, adjusting for urine creatinine concentrations and potential confounding factors. RESULTS 101 (54%) adolescents participated (46 girls; 55 boys). Urinary paraben concentrations were higher in girls than in boys. Methylparaben was positively associated with attention in girls (p ≤ .05; B= -2.836; 95%CI= -5.175;-.497), ethylparaben negatively with hyperactivity (p ≤ .05; B= -1.864; 95%CI= -3.587;-.141). Butylparaben was associated with more optimal scores on parent reported attention. Propylparaben was negatively associated with scores on sustained auditory attention in girls (p ≤ .10; B=.444; 95%CI= -.009;.896). Bisphenol concentrations were not associated with scores on attention and concentration after adjusting for confounders. CONCLUSION In 13-15-year-old Dutch adolescents, urinary concentrations of methylparaben and ethylparaben were associated with better attention and less hyperactivity, whereas a trend toward significance was found between higher urinary propylparaben concentrations and poorer attention. Bisphenol concentrations were not associated with attention and concentration after adjusting for confounders.

Left insular cortical thinning differentiates the inattentive and combined subtype of adult attention-deficit/hyperactivity disorder. J Psychiatr Res 2023; 159:196-204.

Abstract
BACKGROUND Neuroimaging studies in attention-deficit/hyperactivity disorder (ADHD) demonstrated decreased global gray matter volume. In terms of surface parameters, most investigations focused on cortical thickness with a multi-center MEGA-analysis indicating cortical thinning in children, but not in adults with ADHD. In this single-scanner study, for the first time in adult ADHD, we additionally examined metrics beyond cortical thickness and surface area, namely sulcal depth and fractal dimension as measures of cortical alteration and complexity. Unlike most previous studies, ADHD subtypes were considered. METHODS As part of the Comparison of Methylphenidate and Psychotherapy in Adult ADHD Study (COMPAS), surface parameters were analyzed in 131 adults with ADHD (66 combined, 60 inattentive and 5 hyperactive/impulsive subtype) and 95 healthy controls with the Computational Anatomy Toolbox (CAT12) using Statistical Parametric Mapping Software (SPM). RESULTS Neither at the vertex- nor at the region of interest-level, the ADHD and control group differed significantly with regard to cortical thickness, gyrification index, sulcal depth or fractal dimension. Contrasting the combined and the inattentive subtype, patients of the combined subtype showed a significant thinning of the left anterior insular cortex. Thinner left pars opercularis cortical thickness was associated with symptoms of hyperactivity/restlessness. CONCLUSIONS Resembling previous findings of a correlation of the left anterior insular gray matter volume with oppositional symptoms in adolescents with ADHD, we detected left anterior insular cortical thinning in the ADHD combined subtype. Left insular cortical thickness could represent a potential marker to distinguish the predominantly inattentive and the combined ADHD subtype in adulthood.

Abstract
Epigenetic influence plays a role in the association between exposure to air pollution and attention deficit hyperactivity disorder (ADHD); however, research regarding sulfur dioxide (SO2) is scarce. Herein, we investigate the associations between prenatal SO2 exposure and ADHD rating scale (ARS) at ages 4, 6 and 8 years repeatedly in a mother-child cohort (n = 329). Whole blood samples were obtained at ages 2 and 6 years, and genome-wide DNA methylation (DNAm) was analyzed for 51 children using the Illumina Infinium HumanMethylation BeadChip. We analyzed the associations between prenatal SO2 exposure and DNAm levels at ages 2 and 6, and further investigated the association between the DNAm and ARS at ages 4, 6 and 8. Prenatal SO2 exposure was associated with ADHD symptoms. From candidate gene analysis, DNAm levels at the 6 CpGs at age 2 were associated with prenatal SO2 exposure levels. Of the 6 CpGs, cg07583420 (INS-IGF2) was persistently linked with ARS at ages 4, 6 and 8. Epigenome-wide analysis showed that DNAm at 6733 CpG sites were associated with prenatal SO2 exposure, of which 58 CpGs involved in Notch signalling pathway were further associated with ARS at age 4, 6 and 8 years, persistently. DNAm at age 6 was not associated with prenatal SO2 exposure. Changes in DNAm levels associated with prenatal SO2 exposure during early childhood are associated with increases in ARS in later childhood.

Abstract
Background Adverse eating behaviors and a high rate of obesity have been identified among children diagnosed with attention deficit hyperactivity disorder (ADHD). In this study, we investigate the relationships between eating behaviors and body fat mass among children with ADHD. Methods All participants were recruited from the Children's Health Care Department of the Children's Hospital of Nanjing Medical University from June 2019 to June 2020. ADHD was diagnosed according to the diagnostic criteria of the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) by psychiatrists. Core ADHD symptoms defined by the DSM-5 were inattention and hyperactivity/impulsivity. The anthropomorphic indices defined by the World Health Organization (WHO) were utilized in this study (body mass index [BMI], underweight, normal body mass, overweight, obesity, short stature). Body fat mass, fat mass percentage (FM%), skeletal muscle mass, skeletal muscle mass percentage (SMM%) were tested via body composition meter, and eating behaviors were assessed by parents using the Chinese version of the Children's Eating Behavior Questionnaire (CEBQ). The CEBQ was comprised of subscales related to food avoidant behaviors (satiety responsiveness, slowness in eating, fussiness, and emotional undereating) and food approach behaviors (food responsiveness, enjoyment of Food, desire to drink, and emotional overeating). The associations among ADHD, obesity and adverse eating behavior were tested through correlation analysis, and a mediating effect model was established to explore the effect of eating behaviors. Results A total of 548 participants aged 4-12 years were recruited. Among them, 396 were diagnosed with ADHD, with the remaining 152 enrolled in a control group. Compared with the control group, the ADHD group had higher incidences of overweight (22.5% vs. 14.5%) and obesity (13.4% vs. 8.6%) (p < 0.05). The ADHD group was more likely to display "slowness in eating" (11.01 ± 3.32 vs. 9.74 ± 2.95), "fussiness" (15.61 ± 3.54 vs. 15.03 ± 2.84), "food responsiveness" (11.96 ± 4.81 vs. 9.88 ± 3.71) and "desire to drink" (8.34 ± 3.46 vs. 6.58 ± 2.72) (p < 0.05). Moreover, The FM% of children with ADHD was positively correlated with inattention (β = 0.336, 95% CI: 0.001 to 0.673) and "food responsiveness" (β = 0.509, 95% CI: 0.352 to 0.665) in the multiple linear regression model. The mediation effect model showed that "food responsiveness" accounted for a significant portion (64.2%) of the mediating effect. Conclusion Children with ADHD had higher prevalence of overweight and obesity. As an important risk factor, food responsiveness may connect core symptoms of ADHD with obesity.

Abstract
BACKGROUND Observational studies have found an association between attention-deficit/hyperactivity disorder (ADHD) and ischemic stroke. AIMS The purpose of this study was to investigate whether genetic liability to ADHD has a causal effect on ischemic stroke and its subtypes. METHODS In this two-sample Mendelian randomization (MR) study, genetic variants (nine single-nucleotide polymorphisms; P < 5 × 10-8) using as instrumental variables for the analysis was obtained from a genome-wide association study of ADHD with 19,099 cases and 34,194 controls. The outcome datasets for stroke and its subtypes were obtained from the MEGASTROKE consortium, with 40,585 cases and 406,111 controls. MR inverse variance-weighted method was conducted to investigate the effect of genetic liability to ADHD on ischemic stroke and its subtypes. Sensitivity analyses (median-based methods, MR-Egger, MR-robust adjusted profile scores, MR-pleiotropy residual sum and outlier) were also utilized to assess horizontal pleiotropy and remove outliers. Multivariable MR (MVMR) analyses were conducted to explore potential mediators. RESULTS Genetically determined ADHD (per 1 SD) was significantly associated with a higher risk of any ischemic stroke (AIS) (odds ratio (OR) = 1.15, 95% confidence interval (CI) = 1.05-1.25, P = 0.002) and large-artery atherosclerotic stroke (LAS) (OR = 1.40, 95% CI = 1.10-1.76, P = 0.005). The significant association was also found in sensitivity analyses and MVMR analyses. CONCLUSIONS Genetic liability to ADHD was significantly associated with an increased risk of AIS, especially LAS. The association between ADHD and LAS was independent of age of smoking initiation but mediated by coronary artery disease.

Benefits and Risks of Antidepressant Drugs During Pregnancy: A Systematic Review of Meta-analyses. Paediatr Drugs 2023; 25:247-265.

Abstract
BACKGROUND The prescription of antidepressant drugs during pregnancy has been steadily increasing for several decades. Meta-analyses (MAs), which increase the statistical power and precision of results, have gained interest for assessing the safety of antidepressant drugs during pregnancy. OBJECTIVE We aimed to provide a meta-review of MAs assessing the benefits and risks of antidepressant drug use during pregnancy. METHODS Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a literature search on PubMed and Web of Science databases was conducted on 25 October, 2021, on MAs assessing the association between antidepressant drug use during pregnancy and health outcomes for the pregnant women, embryo, fetus, newborn, and developing child. Study selection and data extraction were carried out independently and in duplicate by two authors. The methodological quality of included studies was evaluated with the AMSTAR-2 tool. Overlap among MAs was assessed by calculating the corrected covered area. Data were presented in a narrative synthesis, using four levels of evidence. RESULTS Fifty-one MAs were included, all but one assessing risks. These provided evidence for a significant increase in the risks for major congenital malformations (selective serotonin reuptake inhibitors, paroxetine, fluoxetine, no evidence for sertraline; eight MAs), congenital heart defects (paroxetine, fluoxetine, sertraline; 11 MAs), preterm birth (eight MAs), neonatal adaptation symptoms (eight MAs), and persistent pulmonary hypertension of the newborn (three MAs). There was limited evidence (only one MA for each outcome) for a significant increase in the risks for postpartum hemorrhage, and with a high risk of bias, for stillbirth, impaired motor development, and intellectual disability. There was inconclusive evidence, i.e., discrepant results, for an increase in the risks for spontaneous abortion, small for gestational age and low birthweight, respiratory distress, convulsions, feeding problems, and for a subsequent risk for autism with an early antidepressant drug exposure. Finally, MAs provided no evidence for an increase in the risks for gestational hypertension, preeclampsia, and for a subsequent risk for attention-deficit/hyperactivity disorder. Only one MA assessed benefits, providing limited evidence for preventing relapse in severe or recurrent depression. Effect sizes were small, except for neonatal symptoms (small to large). Results were based on MAs in which overall methodological quality was low (AMSTAR-2 score = 54.8% ± 12.9%, [19-81%]), with a high risk of bias, notably indication bias. The corrected covered area was 3.27%, which corresponds to a slight overlap. CONCLUSIONS This meta-review has implications for clinical practice and future research. First, these results suggest that antidepressant drugs should be used as a second-line treatment during pregnancy (after first-line psychotherapy, according to the guidelines). The risk of major congenital malformations could be prevented by observing guidelines that discourage the use of paroxetine and fluoxetine. Second, to decrease heterogeneity and bias, future MAs should adjust for maternal psychiatric disorders and antidepressant drug dosage, and perform analyses by timing of exposure.

Experience of parents in delivering pediatric tuina to children with symptoms of attention deficit hyperactivity disorder during the COVID-19 pandemic: qualitative findings from focus group interviews. BMC Complement Med Ther 2023; 23:53.

Abstract
BACKGROUND Evidence suggests that pediatric tuina, a modality of traditional Chinese medicine (TCM), might have beneficial effects on the symptoms of attention deficit hyperactivity disorder (ADHD), such as overall improvements in concentration, flexibility, mood, sleep quality, and social functioning. This study was conducted to understand the facilitators and barriers in the delivery of pediatric tuina by parents to children with ADHD symptoms. METHODS This is a focus group interview embedded in a pilot randomized controlled trial on parent-administered pediatric tuina for ADHD in preschool children. Purposive sampling was employed to invite 15 parents who attended our pediatric tuina training program to participate voluntarily in three focus group interviews. The interviews were audio-recorded and transcribed verbatim. The data were analyzed through template analysis. RESULTS Two themes were identified: (1) facilitators of intervention implementation and (2) barriers to intervention implementation. The theme of the facilitators of intervention implementation included the subthemes of (a) perceived benefits to children and parents, (b) acceptability to children and parents, (c) professional support, and (d) parental expectations of the long-term effects of the intervention. The theme of barriers to intervention implementation included the subthemes of (a) limited benefits for children's inattention symptoms, (b) manipulation management difficulties, and (c) limitations of TCM pattern identification. CONCLUSION Perceived beneficial effects on the children's sleep quality and appetite and parent-child relationships, as well as timely and professional support, mainly facilitated the implementation of parent-administered pediatric tuina. Slow improvements in the children's inattention symptoms and the possible inaccuracies of online diagnosis were the dominant barriers of the intervention. Parents have high expectations for the provision of long-term professional support during their practice of pediatric tuina. The intervention presented here can be feasibly used by parents.

Abstract
The Working Memory Index (WMI) in the Wechsler Intelligence Scale for Children (WISC) has been suggested to be associated with ADHD symptoms. The relationship between WMI and ADHD symptoms in the general population is not clear. The study aimed to examine the association between working memory (WM) and behavioral regulation (BR), and hyperactivity/inattention (HI) in a general population sample of 7-8-year-olds, and whether general intellectual functioning is associated with BR and HI. The study also examined if those with low WMI also fulfill elevated ADHD criteria. The study group (N = 865) was assessed with the WISC (Fourth edition), the Behavior Rating Inventory of Executive Function, the Strengths and Difficulties Questionnaire, and the Five to Fifteen Questionnaire, and divided into three groups based on WM function, and in relation to BR and/or HI problems. The associations between WM and BR, and WM and HI, including intellectual functioning as covariate, were examined. WM deficits were found in 22%, but the majority of those had no BR or HI problems. Four percent in the study group had WM deficits combined with BR and/or HI problems, and in about one third of those inattentive ADHD criteria were fulfilled. WM and prosocial behavior were associated with BR and HI. WM deficits measured with WISC WMI in 7-8-year-olds do not always signal BR and/or HI problems.

Abstract
Caring for children with attention-deficit/hyperactivity disorder (CADHD) is stressful for caregivers. Identifying factors related to parenting stress in caregivers of CADHD can facilitate the development of intervention programs. This study aimed to examine the associations between affiliate stigma and various domains of parenting stress among caregivers of CADHD. This study also analyzed the moderating effects of demographic characteristics and the symptoms of childhood ADHD and oppositional defiant disorder (ODD) on the associations between affiliate stigma and parenting stress. In total, 213 caregivers of CADHD participated in this study. Parenting stress was assessed using the Parenting Stress Index, Fourth Edition Short Form (PSI-4-SF). Affiliate stigma was assessed using the Affiliate Stigma Scale. ADHD and ODD symptoms were assessed using the Parent Form of the Swanson, Nolan, and Pelham Scale, Version IV. The results indicated that higher affiliate stigma was significantly associated with greater parenting stress in all three domains of the PSI-4-SF. ODD symptoms increased the magnitude of parenting stress in two domains of parenting stress among caregivers with affiliate stigma. Intervention programs for relieving parenting stress among caregivers of CADHD should take affiliate stigma and child ODD symptoms into consideration.

Remote assessment of ADHD in children and adolescents: recommendations from the European ADHD Guidelines Group following the clinical experience during the COVID-19 pandemic. Eur Child Adolesc Psychiatry 2023; 32:921-935. [PMID: 36764972 PMCID: PMC9918404 DOI: 10.1007/s00787-023-02148-1] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/14/2022] [Accepted: 01/19/2023] [Indexed: 02/12/2023]
Abstract
The COVID-19 pandemic led ADHD services to modify the clinical practice to reduce in-person contact as much as possible to minimise viral spread. This had far-reaching effects on day-to-day clinical practice as remote assessments were widely adopted. Despite the attenuation of the acute threat from COVID, many clinical services are retaining some remote practices. The lack of clear evidence-based guidance about the most appropriate way to conduct remote assessments meant that these changes were typically implemented in a localised, ad hoc, and un-coordinated way. Here, the European ADHD Guidelines Group (EAGG) discusses the strengths and weaknesses of remote assessment methods of children and adolescents with ADHD in a narrative review based on available data and expert opinions to highlight key recommendations for future studies and clinical practice. We conclude that going forward, despite remote working in clinical services functioning adequately during the pandemic, all required components of ADHD assessment should still be completed following national/international guidelines; however, the process may need adaptation. Social restrictions, including changes in education provision, can either mask or exacerbate features associated with ADHD and therefore assessment should carefully chart symptom profile and impairment prior to, as well as during an ongoing pandemic. While remote assessments are valuable in allowing clinical services to continue despite restrictions and may have benefits for routine care in the post-pandemic world, particular attention must be paid to those who may be at high risk but not be able to use/access remote technologies and prioritize these groups for conventional face-to-face assessments.

ADHD Follow-Up in Adulthood among Subjects Treated for the Disorder in a Child and Adolescent Mental Health Service from 1995 to 2015. MEDICINA (KAUNAS, LITHUANIA) 2023; 59:medicina59020338. [PMID: 36837537 PMCID: PMC9966311 DOI: 10.3390/medicina59020338] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 12/18/2022] [Revised: 02/03/2023] [Accepted: 02/06/2023] [Indexed: 02/12/2023]
Abstract
Background and Objectives: ADHD is a neurodevelopmental disorder characterized by inattention and hyperactivity/impulsivity and can persist in adulthood. The aim of this study is to deepen knowledge about adult ADHD follow-up. Materials and Methods: This observational study consists of one retrospective part aimed at collecting records of children and adolescents treated for ADHD in the Children and Adolescent Mental Health Service (CAMHS) from 1995 to 2015 and, successively, at identifying their adult follow-up in Adult Mental Health Service (AMHS); the second part consists of ADHD scale administration, Diagnostic Interview for ADHD in Adults (DIVA 2-0) and Adult Self Rating Scale (ASRSv1.1), for the subjects currently being treated at AMHS who agreed to participate in the study. Results: We observed that among the 55 patients treated at CAMHS between 1995 and 2015 for ADHD and subsequently at the AMHS, none presented a diagnosis of ADHD; instead, they were treated for Intellectual Dysfunction (33%), Borderline Personality Disorder (15%) and Anxiety Disorders (9%), and two individuals were also diagnosed with comorbid substance/alcohol abuse (4%). Of the 55 patients, only 25 (45%) were treated at AMHS during the study period. Though we asked for their informed consent to administer the questionnaires, we were able to test only seven patients. The ASRS-V1.1 score showed that 43% of patients reported symptoms of ADHD persistence in adulthood. For DIVA 2.0, 57% of individuals reported scores indicating the persistence of the ADHD inattention component, and 43% the persistence of both ADHD dimensions. Conclusions: ADHD cannot be considered a disorder confined to childhood/adolescence but instead is a chronic and complex condition that can persist into adulthood. The very small size of our final sample may account for both the high ADHD dropout rate over the long follow-up period and the difficult transition from child to adult health care in ADHD treatment. Our investigation suggests the need for specific training in the diagnosis and treatment of adult ADHD and the implementation of transition protocols between minor and adult services to improve long-term treatments.

Associations of These Self-control-Boosting Strategies with Juvenile Violence at the State Level. JOURNAL OF DEVELOPMENTAL AND LIFE-COURSE CRIMINOLOGY 2023; 9:1-35. [PMID: 36789240 PMCID: PMC9910267 DOI: 10.1007/s40865-023-00223-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 07/03/2022] [Revised: 01/15/2023] [Accepted: 01/16/2023] [Indexed: 06/18/2023]
Abstract
The increasing rates at which psychotropic drugs have been prescribed to children and adolescents in the USA in the last three decades (since the early 1990s) have prompted questions about whether this trend is associated with the "great American crime decline." Medicalization can be considered one of the strategies to remedy children's neuropsychological deficits and improve their self-control. Another possible remedy is school-based services for children with learning disabilities, mandated by the Individuals with Disabilities Education Improvement Act (IDEA) of 2004. Using state-level panel data analyses for years 1990-2014 (with the main focus on 2000-2014 outcomes), the current study estimates associations between these two developmental self-control remedies-medicalization and school-based services-and minor, moderate, and severe types of juvenile violence, while controlling for relevant covariates (both time-varying and time-invariant). The results of mixed-effects linear regression analyses accounting for powerful time trends show a strong association between increases in school-based services for children with learning disabilities and declines in all types of juvenile violence. Another strong and consistent finding that emerges in the analyses is the link between reductions in child poverty at the state level and decreases in juvenile violence, both contemporaneously and over time. Psychotropic drug prescribing to children (measured using Supplemental Security Income rolls of children with mental health conditions) exhibits inconsistent or insignificant effects. The findings of this study have substantial theoretical and policy implications and indicate the importance of strengthening school-based services for children with disabilities and reducing child poverty as essential violence prevention tools.

Abstract
Background Studies have shown that young maternal age at childbirth can increase the risk of attention-deficit/hyperactivity disorder (ADHD) in offspring, but a study of the U.S. population has not been reported. Moreover, there is no reported research on young and advanced maternal age at childbirth and whether it can contribute to the risk of learning disability (LD) in offspring. Methods This study evaluated the association between young and advanced maternal age at childbirth and offspring risk of ADHD and LD in the U.S. population. Using data from 8,098 participants included in the National Health and Nutrition Examination Survey (NHANES) conducted in 1999-2004, we analyzed the association between maternal age at childbirth and ADHD and LD risk in offspring. Odds ratios (ORs) and 95% confidence intervals (CIs) for maternal age at childbirth in association with ADHD and LD risk in offspring were estimated using multivariate logistic regression models after adjustment for age, sex, race, body mass index (BMI), poverty income ratio, smoking status during pregnancy, and NHANES cycle. Restricted cubic spline (RCS) models were used to evaluate potential non-linear relationships. Sensitivity analyses were performed to ensure the reliability of the results. Results Among all participants, the offspring of subjects with a maternal age at childbirth of 18-24 years had an increased risk of ADHD (OR = 1.34, 95% CI: 1.01, 1.79) and LD (OR = 1.36, 95% CI: 1.06, 1.79) or either ADHD or LD (OR = 1.48, 95% CI: 1.20, 1.81). Additionally, compared with subjects with a maternal age at childbirth of 25-29 years, subjects with a maternal age at childbirth of 35-39 years had lower odds of having offspring with ADHD (OR = 0.60, 95% CI: 0.36, 1.00) and higher odds of having offspring with LD (OR = 1.34, 95% CI: 1.01, 1.78). The relationship between maternal age at childbirth and LD risk presented a U-shaped curve. Conclusions These results provide epidemiological evidence showing that young and advanced maternal age at childbirth are associated with ADHD and LD risk.

Abstract
OBJECTIVE A growing literature suggests attention-deficit/hyperactivity disorder (ADHD) is a heritable disorder. We evaluated children at risk for ADHD by virtue of having parents with ADHD and compared them with children of parents without ADHD to assess the degree of heritability of ADHD. METHOD The sample for this study was derived from three longitudinal studies that tracked families with various disorders, including ADHD. Children were stratified based on presence of parental ADHD, and clinical assessments were taken to evaluate presence of ADHD and related psychiatric and functional outcomes in children. RESULTS Children with parental ADHD had significantly more full or subthreshold psychiatric disorders (including ADHD) as well as functional impairments compared to children without parental ADHD. CONCLUSION Our findings suggest that offspring of parents with ADHD are at significant risk for ADHD and its associated psychiatric, cognitive, and educational impairments. These findings aid in identifying early manifestations of ADHD in young children at risk.

Abstract
The present article outlines the development of the parent-reported ADHD symptom infrequency scale (PRASIS), a novel stand-alone questionnaire designed to discriminate between parents exaggerating ratings of ADHD symptoms of their child from parents more accurately reporting symptoms. The PRASIS includes an Infrequency scale (INF) to measure infrequently reported symptoms of ADHD and a clinical scale to measure Diagnostic and Statistical Manual of Mental Disorders-5th Edition (DSM-5) defined ADHD symptoms (ADHD Total). An initial list of infrequency and clinical items was revised over the course of three studies, each conducted on a different sample of participants (n1 = 154, n2 = 203, n3 = 167) recruited via CloudResearch and consisting of mothers of children 4-12 years old. Analyses on the final version of the measure demonstrated good to excellent internal consistency (INF α = .87 , ADHD Total α = .94) and high convergent validity of the PRASIS ADHD Total scores with ADHD Rating Scale-5 Total scores (r = .87, p < .001). Omnibus ANOVA comparisons demonstrated excellent group discrimination of both the PRASIS Infrequency scale and the PRASIS ADHD scale (Cohen's f = 0.81-0-90). Specificity was above the minimum requirement set a priori (≥.80) and resulting sensitivity was similar or higher than other non-ADHD measures in the symptom validity literature. Specificity and sensitivity are reported for multiple cutoff scores, and positive predictive values (PPV) and negative predictive values (NPV) are presented for several base rates.

The study of rs324420 (C385A) polymorphism of the FAAH gene of the endocannabinoid system in patients with epilepsy and ADHD. Epilepsy Res 2023; 192:107100. [PMID: 37018974 DOI: 10.1016/j.eplepsyres.2023.107100] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2022] [Revised: 01/24/2023] [Accepted: 01/30/2023] [Indexed: 02/05/2023]
Abstract
The endocannabinoid (eCB) system regulates many physiological functions in the central nervous system. Fatty acid amide hydrolase (FAAH) is an essential enzyme in the eCB system, degrading anandamide. Single nucleotide polymorphism (SNP) rs324420 is a common genetic polymorphism of the FAAH gene and has been associated with susceptibility to neurological conditions. This study examined whether the SNP rs324420 (C385A) is associated with epilepsy and attention deficit hyperactivity disorder (ADHD). This study consists of two case-control parts. The first part comprises 250 epilepsy subjects and 250 healthy individuals as controls. The second one comprises 157 cases with ADHD and 136 healthy individuals as controls. Genotyping was carried out using polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP) technique. Interestingly, the FAAH C384A genotype (OR 1.755, 95 % CI 1.124-2.742, p = 0.013) and allele (OR 1.462, 95 % CI 1.006-2.124, p = 0.046) distribution showed an association with generalized epilepsy. On the other hand, this SNP was not associated with the risk of ADHD. To our knowledge, there was no study on the association between rs324420 (C385A) polymorphism and the risks of ADHD or epilepsy. This study provided the first evidence of an association between generalized epilepsy and rs324420 (C385A) of FAAH. Larger sample sizes and functional studies are warranted to explore the clinical utility of FAAH genotyping as a possible marker for increased generalized epilepsy risk.

Abstract
OBJECTIVE There are no definitive results about either the presence of exact comorbidity between celiac disease (CD) and attention-deficit/hyperactivity disorders (ADHD) or etiology. We intend to screen ADHD-related cognitive and behavioral traits in children with biopsy-proven CD and investigate the possible association of these traits with certain vitamin levels, body-mass index, and gluten-free diet (GFD) compliance. METHOD A total of 85 children with biopsy-proven CD (the ages of 8-18 years) were compared with age and sex-matched 72 healthy controls in terms of demographics, psychiatric symptoms, certain vitamin levels, and anthropometric measurements. RESULTS ADHD-like cognitive issues, such as inattention and learning difficulties, as well as psychosomatic symptoms and poor prosocial behavior, were all associated with GFD noncompliance in childhood CD. CONCLUSION Untreated CD may predispose to ADHD-resembling symptoms. Physicians should be aware of the probability of ADHD misdiagnosing due to ADHD-resembling cognitive and behavioral traits in untreated CD.

Abstract
UNLABELLED This study examined the relationship between gestational age and long-term outcomes up to 6 years of age using population-based big data from the National Health Insurance Service in Korea. This retrospective observational cohort study used data from the National Health Information Database (2011-2017). All children born in Korea during 2011 (January 1-December 31) were eligible and were followed up until 2017. Gestational age groups were divided into extremely preterm (< 28 weeks), very preterm (28-31 weeks), moderate-to-late preterm (32-36 weeks), and full-term (37-41 weeks). The survival rate, neurodevelopmental diseases, hearing or visual impairment, and respiratory morbidities were compared for each gestational age group. In total, 370,301 children were included in the analysis. The total survival rate increased with increasing gestational age. Furthermore, the risk of neurodevelopmental diseases (i.e., epilepsy, cerebral palsy, delayed development, mental retardation, language disorder, developmental coordination disorder, autism spectrum disorder), hearing or visual impairment, and asthma-related inhaler prescription increased with decreasing gestational age, despite adjustment for covariates. CONCLUSION Lower gestational age was associated with an increase in a wide spectrum of adverse neurodevelopmental and respiratory outcomes in the first 6 years of life. Although morbidities were highest at the earliest gestational ages, moderate-to-late preterm children were significantly associated with increased adverse outcomes compared with full-term children. Our findings prove this under-recognized group's long-term follow-up and policy support. WHAT IS KNOWN • Infants born preterm are at high risk for neurodevelopmental and various medical health problems. • Nationwide research on long-term outcomes for moderate-to-late preterm birth is sparse. WHAT IS NEW • In this nationwide cohort study, lower gestational age at birth was inversely associated with increased adverse neurodevelopmental and respiratory outcomes in the first 6 years of life. • Long-term follow-up and policy support are required for moderate-to-late preterm children who are at risk of increased adverse outcomes compared with full-term births.

Abstract
BACKGROUND Attention-deficit/hyperactivity disorder (ADHD) is characterized by substantial interindividual heterogeneity that challenges the systematic assessment and treatment. Considering mixed evidence from previous neurofeedback research, we present a novel feedback system that relies on gaze behavior to detect signs of inattention while performing a neuropsychological attention task in a virtual seminar room. More specifically, an audiovisual feedback was given whenever participants averted their gaze from the given task. METHODS Eighteen adults with ADHD and 18 healthy controls performed a continuous performance task (CPT) in virtual reality under three counterbalanced conditions in which either gaze-based feedback, sham feedback, or no feedback was provided. In all conditions, phases of high and low virtual distraction alternated. CPT errors and reaction times, proportions of gaze dwell times (e.g., task focus or distraction focus), saccade characteristics, EEG theta/beta ratios, head movements, and an experience sampling of ADHD symptoms were analyzed. RESULTS While patients can be discriminated well from healthy controls in that they showed more omission errors, higher reaction times, higher distraction-related dwell times, and more head movements, the feedback did not immediately improve task performance. It was also indicated that sham feedback was rather associated with an aggravation of symptoms in patients. CONCLUSIONS Our findings demonstrate sufficient suitability and specificity for this holistic ADHD symptom assessment. Regarding the feedback, a single-session training was insufficient to achieve learning effects based on the proposed metacognitive strategies. Future longitudinal, multi-session trials should conclusively examine the therapeutic efficacy of gaze-based virtual reality attention training in ADHD.

Abstract
PURPOSE Based on eight research criteria, this study examines the feasibility of a 5-week Family Strength-Oriented Therapeutic Conversation (FAM-SOTC) for caregivers of adolescents diagnosed with attention deficit hyperactivity disorder (ADHD); this intervention aims to improve outcomes of both caregivers and adolescents. DESIGN AND METHODS The FAM-SOTC intervention was implemented at an adolescent psychiatric outpatient unit with 10 caregivers of 10 adolescents diagnosed with ADHD. The feasibility criteria were addressed through survey responses, diary reports, and a one-group pre- and posttest quasi-experimental design. FINDINGS The assessment of eight feasibility criteria showed promising results for the further evaluation of the intervention. PRACTICAL IMPLICATIONS This feasibility study has produced promising results, which represent a step toward a more extensive study, designed to evaluate a protocol that may offer educational and supportive programs for families of adolescents with ADHD, enhancing their self-management behavior. Further studies are warranted to test the FAM-SOTC intervention using a larger sample.

Abstract
Background Previous studies have argued that attention deficit hyperactivity disorder (ADHD) is associated with asthma. However, reliable evidence to verify this association has not yet been reported. Objectives To investigate the bidirectional association between asthma and ADHD through a 12-year big data cohort study. Methods The independent variable group was extracted from 3.5 million individuals randomly sampled by the National Health Insurance Service (NHIS). In Study 1, the incidence of ADHD according to asthma was evaluated, while in Study 2, the incidence of asthma according to ADHD was analyzed. Propensity score (PS) matching with several variables was used to obtain a control group. Measurements and main results In Study 1, the asthma group included 131,937 individuals and the non-asthma group included 131,937 individuals. The adjusted hazard ratio (aHR) for ADHD in the asthma group was 1.17 [95% confidence interval (CI): 1.11-1.23]. In subgroup analysis, the aHRs for ADHD of individuals in the subgroups male sex, 0-5 years old, 6-10 years old, atopic dermatitis, allergic rhinitis, Charlson comorbidity index (CCI) 1, and CCI > 2 were significant (aHR: 2.83, 1.70, 1.79, 1.09, 1.15, 1.06, and 1.49, respectively). In Study 2, ADHD was found to significantly affect asthma in all age groups (aHRs of the subgroups 0∼60 and 0∼17 years old were 1.10 and 1.09, respectively). In the 0∼17 years old subgroup, the association of ADHD with asthma was greater with younger age (aHRs of the subgroups 0∼5 and 6∼10 years old were 2.53 and 1.54, respectively). Conclusion From long-term follow-up, the incidence of ADHD was 1.17 times higher in the asthma group than in the control group. The incidence of asthma was 1.10 times higher in the ADHD group than in the control group. Asthma and ADHD have a bidirectional relationship, and childhood asthma and ADHD should be rigorously managed.

Abstract
Objective.Previous studies have demonstrated that transcranial ultrasound stimulation (TUS) with noninvasive high penetration and high spatial resolution has an effective neuromodulatory effect on neurological diseases. Attention deficit hyperactivity disorder (ADHD) is a persistent neurodevelopmental disorder that severely affects child health. However, the neuromodulatory effects of TUS on ADHD have not been reported to date. This study aimed to investigate the neuromodulatory effects of TUS on ADHD.Approach.TUS was performed in ADHD model rats for two consecutive weeks, and the behavioral improvement of ADHD, neural activity of ADHD from neurons and neural oscillation levels, and the plasma membrane dopamine transporter and brain-derived neurotrophic factor (BDNF) in the brains of ADHD rats were evaluated.Main results.TUS can improve cognitive behavior in ADHD rats, and TUS altered neuronal firing patterns and modulated the relative power and sample entropy of local field potentials in the ADHD rats. In addition, TUS can also enhance BDNF expression in the brain tissues.Significance. TUS has an effective neuromodulatory effect on ADHD and thus has the potential to clinically improve cognitive dysfunction in ADHD.

Abstract
BACKGROUND ADHD is associated with deficits in executive functions. Cognitive training is a promising nonpharmacological intervention for ADHD, however, there is insufficient evidence to guide the selection of training for individuals with ADHD. This pilot study aims to investigate the efficacy of executive function training targeting key executive dysfunctions in ADHD, compared with general executive function training which targets other executive functions. METHODS A total of 127 subjects (6-12 years) diagnosed with ADHD were allocated to receive one of two different cognitive trainings. ADHD symptoms and cognitive functions were evaluated using parent-rated scales and CANTAB cognitive assessments. All participants were required to complete 48 training sessions within a two-month period. RESULTS 94 out of 127 children completed the required training and assessments. Both ADHD executive function training group and general executive function training group showed significant improvement in ADHD symptoms on the ADHD Rating Scale and in executive function on the assessment of CANTAB. There was no significant difference in improvements between the two groups. Subgroup analysis suggested that children who had ADHD-RS total scores less than or equal to 28 at baseline showed greater improvement following ADHD executive function training. CONCLUSIONS This study indicates that cognitive training can improve ADHD symptoms and executive function, with no difference in efficacy between targeted and generalized cognitive training. In addition, individuals with lower symptom severity may benefit more from training targeting key ADHD executive dysfunctions.

Abstract
Objective This work is to investigate the alterations of the central 5-hydroxytryptamine (5-HT) system in spontaneously hypertensive rats (SHR) and the correlation with the behaviors of SHR, and to explore the effects of glucocorticoid intervention on the central 5-HT system and SHR behaviors. Materials and methods Three weeks old SHR were chosen as the attention-deficit hyperactivity disorder (ADHD) model and treated with glucocorticoid receptor (GR) agonist or inhibitor, whereas Wista Kyoto rats (WKY) were chosen as the normal control group. Open-field test and Làt maze test were used to evaluate the spontaneous activities and non-selective attention. The levels of 5-HT in the extracellular fluid specimens of the prefrontal cortex of rats were analyzed by high-performance liquid chromatography. The expressions of GR, 5-HT1A receptor (5-HT1AR), and 5-HT2A receptor (5-HT2AR) in the prefrontal cortex were analyzed through immunohistochemistry. Results Our study demonstrated that the 5-HT level was lower in the prefrontal cortex of SHR compared to that of WKY. The Open-field test and Làt maze test showed that GR agonist (dexamethasone, DEX) intervention ameliorated attention deficit and hyperactive behavior, whereas GR inhibitor (RU486) aggravated the disorders. With DEX, the expression levels of 5-HT and 5-HT2AR in the prefrontal cortex of SHR were significantly higher than those in the control group, whereas the expression level of 5-HT1AR was lower. However, the expression levels of 5-HT and 5-HT2AR were significantly decreased after the intervention with RU486, while the expression level of 5-HT1AR increased. Results showed that glucocorticoid was negatively correlated with 5-HT1AR and positively correlated with 5-HT2AR. Conclusion In the prefrontal cortex of ADHD rats, the down-regulation of 5-HT and 5-HT2AR expressions and the up-regulation of 5-HT1AR, compared with WYK rats, suggested a dysfunctional central 5-HT system in ADHD rats. The GR agonist can upregulate the expression of 5-HT and 5-HT2AR and downregulate the expression of 5-HT1AR in the prefrontal cortex of SHR as well as reduce the hyperactivity and attention deficit behavior in SHR, while the opposite was true for the GR inhibitor. It is suggested that the dysfunction of the 5-HT system in ADHD rats is closely related to glucocorticoid receptor activity.

Association between maternal polycystic ovary syndrome and attention-deficit/hyperactivity disorder in offspring aged 3-6 years: A Chinese population-based study. Front Public Health 2023; 10:1032315. [PMID: 36699874 PMCID: PMC9868860 DOI: 10.3389/fpubh.2022.1032315] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2022] [Accepted: 12/20/2022] [Indexed: 01/11/2023] Open
Abstract
Background Maternal polycystic ovary syndrome (PCOS) may increase the risk of attention-deficit/hyperactivity disorder (ADHD) in offspring; however, their association remains unexplored in Asian populations. Hence, this study aimed to investigate the association between maternal PCOS and ADHD in offspring aged 3-6 years and whether it differed by offspring sex. Methods This was a district-wide population-based study of 87,081 preschoolers from 234 kindergartens in Longhua District, Shenzhen, China. The parents were invited to complete a self-administrated questionnaire covering information on socio-demographics, maternal disease history, and child behavior. ADHD symptoms were measured with the parent-rating 26-item Swanson, Nolan, and Pelham Rating Scale (SNAP-IV). Logistic regression was performed to examine the associations between maternal PCOS and ADHD symptoms in offspring. Results The response rate was 80% and 63,390 mother-child pairs were included. Of the mothers, 1,667 (2.6%) reported PCOS diagnoses. The mean age of children at ADHD assessment was 4.86 ± 0.84[SD] years, and 53.6% were boys. Children with maternal PCOS had a higher risk of developing ADHD symptoms than other children (12.0 vs. 9.4%, adjusted odds ratio [OR] = 1.32, 95% CI: 1.13-1.54). The risk estimate was significant in boys (adjusted OR = 1.38, 95% CI: 1.14-1.66) but not in girls (adjusted OR = 1.23, 95% CI: 0.94-1.57, P for interaction = 0.391). Treatment of PCOS tended to be associated with a lower risk of ADHD symptoms than untreated PCOS albeit risk confidence intervals were overlapped (treated: adjusted OR = 1.28, 95% CI: 1.06-1.54 vs. untreated: adjusted OR = 1.14, 95% CI: 1.08-1.83). Conclusion Maternal PCOS increases the risk of developing ADHD in offspring, especially boys. Further studies are warranted to confirm our findings, and early neurodevelopmental screening may be needed in children born to mothers with PCOS.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2023; 20:1032. [PMID: 36673793 PMCID: PMC9859519 DOI: 10.3390/ijerph20021032] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/12/2022] [Revised: 12/29/2022] [Accepted: 01/04/2023] [Indexed: 06/17/2023]
Abstract
This systematic review and meta-analysis aimed to systematically evaluate the effect of physical activity (PA) on inhibitory function in children with ADHD. Experimental studies on the effect of PA on the inhibitory function of children with ADHD were retrieved. The data were obtained from PubMed, The Cochrane Library, Web of Science, EBSCO (MEDLINE, APA Psyclnfo, ERIC), Embase, Scopus, and ProQuest. The search period was from the date of inception of the respective databases to 4 May 2022, and Reviewer Manager software (version 5.3) was used for analysis. Eleven articles and 713 samples were included in the meta-analysis. Results revealed that PA can significantly improve the inhibitory function of children with ADHD (SMD = 0.78, 95% CI: 0.45−1.10, p < 0.001). Subgroup analysis showed that the effectiveness of PA as an intervention in improving the inhibitory function of children with ADHD was moderated by the frequency, intensity, duration, type, and length of intervention. Based on the findings, PA can effectively improve interference suppression inhibitory function in children with ADHD. Longitudinal open-skill exercise for 60 min or more, two times/week has the best effect on improving inhibitory function in children with ADHD.

Abstract
Objectives There is an ongoing debate about the restrictive inattentive (RI) presentation of attention deficit hyperactivity disorder (ADHD). The current study aimed to systematically investigate the clinical, neuropsychological, and brain functional characteristics of children with ADHD restrictive inattentive presentation. Methods A clinical sample of 789 children with or without ADHD participated in the current study and finished clinical interviews, questionnaires, and neuropsychological tests. Those individuals with a diagnosis of ADHD were further divided into three subgroups according to the presentation of inattentive and/or hyperactive/impulsive symptoms, the ADHD-RI, the ADHD-I (inattentive), and the ADHD-C (combined) groups. Between-group comparisons were carried out on each clinical and neuropsychological measure using ANCOVA, with age and sex as covariates. Bonferroni corrections were applied to correct for multiple comparisons. Two hundred twenty-seven of the subjects also went through resting-state functional magnetic resonance imaging scans. Five ADHD-related brain functional networks, including the default mode network (DMN), the dorsal attention network (DAN), the ventral attention network, the executive control network, and the salience network, were built using predefined regions of interest (ROIs). Voxel-based group-wise comparisons were performed. Results Compared with healthy controls, all ADHD groups presented more clinical problems and weaker cognitive function. Among the ADHD groups, the ADHD-C group had the most clinical problems, especially delinquent and aggressive behaviors. Regarding cognitive function, the ADHD-RI group displayed the most impaired sustained attention, and the ADHD-C group had the worst response inhibition function. In terms of brain functional connectivity (FC), reduced FC in the DMN was identified in the ADHD-C and the ADHD-I groups but not the ADHD-RI group, compared to the healthy controls. Subjects with ADHD-I also presented decreased FC in the DAN in contrast to the control group. The ADHD-RI displayed marginally significantly lower FC in the salience network compared to the ADHD-I and the control groups. Conclusion The ADHD-RI group is distinguishable from the ADHD-I and the ADHD-C groups. It is characterized by fewer externalizing behaviors, worse sustained attention, and better response inhibition function. The absence of abnormally high hyperactive/impulsive symptoms in ADHD-RI might be related to less impaired brain function in DMN, but potentially more impairment in the salience network.

The impact of attention-deficit/hyperactivity disorder and specific learning disorders on academic performance in Spanish children from a low-middle- and a high-income population. Front Psychiatry 2023; 14:1136994. [PMID: 37124266 PMCID: PMC10130398 DOI: 10.3389/fpsyt.2023.1136994] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/03/2023] [Accepted: 03/20/2023] [Indexed: 05/02/2023] Open
Abstract
Introduction Past research has demonstrated that attention-deficit/hyperactivity disorder (ADHD), specific learning disorders (SLD), and socioeconomic status (SES) affect a host of educational outcomes. However, there are no studies examining whether SES moderates the association between these neurodevelopmental disorders (ND) and the academic achievement of children and adolescents. The present investigation examined the impact of ADHD and SLD on academic performance in 1,287 Spanish students aged 5-17 from a low-middle (LM)- and a high-income population, when adjusted for comorbidity and demographic factors that may influence educational functioning. Methods Parents completed a questionnaire regarding demographic data along with the Strengths and Difficulties Questionnaire. Additionally, teachers provided information on learning difficulties trough the Protocol for Detection and Management of Dyslexia. Teacher's Version. Academic performance across multiple domains (i.e., first language, foreign language, mathematics) was obtained from school records. ND were determined using standardized diagnostic methods based on the Diagnostic and Statistical Manual of Mental Disorders criteria. To examine the effects of ADHD and SLD on academic achievement and the potential moderating role of SES, a series of ordinal logistic regressions were conducted. Results Emotional/behavioral problems, learning difficulties, and ND were more frequent among individuals from the LM-income population. After controlling for gender, age, parental divorce/separation, grade retention, frequency of screen use, and daily meals, both ADHD and SLD were associated with worse educational outcomes. Lower SES also increased the risk for academic impairment, although the interactions with ADHD or SLD were not significant. Conclusion These findings indicate that ADHD and SLD exert a pervasive impact on academic performance across different socioeconomic backgrounds. Therefore, early detection and effective intervention strategies aimed at students with these ND are crucial to improve their educational functioning and mitigate the negative consequences related to academic problems.

Association between long-term ambient ozone exposure and attention-deficit/hyperactivity disorder symptoms among Chinese children. ENVIRONMENTAL RESEARCH 2023; 216:114602. [PMID: 36265606 DOI: 10.1016/j.envres.2022.114602] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/11/2022] [Revised: 10/05/2022] [Accepted: 10/13/2022] [Indexed: 06/16/2023]
Abstract
BACKGROUND Although ozone exposure has neurological toxicity, it remains unclear whether it was associated with an increased risk of attention-deficit/hyperactivity disorders (ADHD) among childhood. METHODS We matched the four-year average ozone concentration with questionnaire data for 35,103 children aged 3-12 years from seven cities in Liaoning, China, 2012-2013. Using mixed-effect logistic regression models, we assessed the association of ozone concentration with multiple ADHD indicators using the Conners Abbreviated Symptom Questionnaire (C-ASQ), including explicit attention-deficit/hyperactivity symptoms (ADHD; score ≥15), attention-deficit/hyperactivity disorder tendencies (ADHD-T; 11 ≤ score ≤14), and attention-deficit/hyperactivity problems (ADHP; score ≥11). Results were also stratified by sociodemongraphics. RESULTS After adjusting for covariates, we found that each interquartile range (IQR) increase in ozone concentration was associated with an increased risk of ADHD, ADHD-T, and ADHP (P < 0.001) with an odds ratio of 1.12 (95% confidence interval, 1.04-1.21), 1.08 (1.03-1.13), and 1.09 (1.05-1.14), respectively. Additionally, we found greater effect estimates in children who reported longer exercise time (vs those with limited exercise time) with odds ratio of 1.18 (1.07-1.31) vs 1.06 (0.96-1.17) for ADHD, 1.13 (1.06-1.21) vs 1.03 (0.96-1.10) for ADHD-T, and 1.15 (1.08-1.21) vs 1.04 (0.98-1.10) for ADHP. Non-breastfed children were also shown to be more vulnerable to ADHD with an odds ratio of 1.22 (1.09-1.36) compared with 1.06 (0.96-1.16) among the rest. CONCLUSIONS Long-term ozone exposure may be associated with increased ADHD among children. Additional studies are needed to validate our findings and support policies and interventions to address this growing public health concern.

Abstract
Background: Attention deficit hyperactivity disorder (ADHD) has in several studies been linked to substance use, including cannabis use. However, crucial gaps remain regarding how to understand this association. Analyzing the association between ADHD and substance use is complicated because of a pronounced overlap between ADHD, conduct problems, and traits such as sensation-seeking. Objectives: Using data from a large and nationally representative study among Swedish adolescents, this study explored the role of conduct problems, but also of sensation-seeking, in accounting for the association between ADHD and cannabis use. Results: There was a notable association between ADHD and cannabis use that was attenuated when conduct problems were controlled for. The association between cannabis use and conduct problems, in turn, was attenuated when sensation-seeking was controlled for. Individuals with both ADHD and conduct problems were more likely to have used cannabis than individuals with ADHD only, but not compared with individuals with conduct problems only. Conclusions: Whereas conduct problems largely explain the link between ADHD and cannabis use, sensation-seeking seems to account for the association between conduct problems and cannabis use.

Abstract
Calcium (Ca2+) comprises a critical ionic second messenger in the central nervous system that is under the control of a wide array of regulatory mechanisms, including organellar Ca2+ stores, membrane channels and pumps, and intracellular Ca2+-binding proteins. Not surprisingly, disturbances in Ca2+ homeostasis have been linked to neurodegenerative disorders, such as Alzheimer's and Parkinson's diseases. However, aberrations in Ca2+ homeostasis have also been implicated in neuropsychiatric disorders with a strong neurodevelopmental component including autism spectrum disorder (ASD) attention-deficit hyperactivity disorder (ADHD) and schizophrenia (SCZ). While plasma membrane Ca2+ channels and synaptic Ca2+-binding proteins have been extensively studied, increasing evidence suggests a prominent role for intracellular Ca2+ stores, such as the endoplasmic reticulum (ER), in aberrant neurodevelopment. In the context of the current mini-review, we discuss recent findings implicating critical intracellular Ca2+-handling regulators such as the sarco-ER Ca2+ ATPase 2 (SERCA2), ryanodine receptors (RyRs), inositol triphosphate receptors (IP3Rs), and parvalbumin (PVALB), in the emergence of ASD, SCZ, and ADHD.

Abstract
Objective Previous studies indicated that maternal thyroid dysfunction increase the offspring's risk for attention deficit/hyperactivity disorder (ADHD). However, the relationship between thyroid function and symptoms in children with ADHD remains unclear. Methods A total of 49 children with ADHD were enrolled. The Conners 3 scale was used to estimate the symptoms associated with ADHD. Correlation between thyroid hormones and the scores of the Conners 3 scale was evaluated by Pearson correlation analysis. Then, ADHD children were divided into two groups according to the hyperactivity index (HI) of the Conners 3 scale: ADHD children with hyperactivity behaviors (HB) (HI > 1.5) and ADHD children without HB (HI < 1.5). The demographic characteristics, thyroid hormones, and routine laboratory parameters between the two groups were collected. To distinguish HI-related factors, a univariate analysis and a binary logistic regression predictive model were used. The discriminative ability of thyroid stimulating hormone (TSH) in predicting ADHD children with HB from ADHD children without HB was investigated using the receiver operating characteristic (ROC) curve method. Results The levels of TSH were positively correlated to the scores of the Conners 3 scale (r = 0.338, P = 0.033) and HI (r = 0.371, P = 0.019). Moreover, the levels of TSH, serum ferritin, and lactic acid were significantly increased in ADHD children with HB compared to ADHD children without HB (all P < 0.05). Furthermore, the results of binary logistic regression found that TSH (OR 2.243 (CL 1.052-4.783)) and lactic acid (OR 1.018 (CI 1.003-1.032)) were independently associated with HI. Additionally, ROC analysis indicated the potential diagnostic value of TSH in discriminating ADHD children with HB from ADHD children without HB with an AUC of 0.684. Conclusion These results suggested that the serum TSH levels may be related to the HB in children with ADHD.

Abstract
Alzheimer's disease (AD) is the most common neurodegenerative disorder with the majority of patients classified as sporadic AD (sAD), in which etiopathogenesis remains unresolved. Though sAD is argued to be a polygenic disorder, apolipoprotein E (APOE) ε4, was found three decades ago to pose the strongest genetic risk for sAD. Currently, the only clinically approved disease-modifying drugs for AD are aducanumab (Aduhelm) and lecanemab (Leqembi). All other AD treatment options are purely symptomatic with modest benefits. Similarly, attention-deficit hyperactivity disorder (ADHD), is one of the most common neurodevelopmental mental disorders in children and adolescents, acknowledged to persist in adulthood in over 60% of the patients. Moreover, for ADHD whose etiopathogenesis is not completely understood, a large proportion of patients respond well to treatment (first-line psychostimulants, e.g., methylphenidate/MPH), however, no disease-modifying therapy exists. Interestingly, cognitive impairments, executive, and memory deficits seem to be common in ADHD, but also in early stages of mild cognitive impairment (MCI), and dementia, including sAD. Therefore, one of many hypotheses is that ADHD and sAD might have similar origins or that they intercalate with one another, as shown recently that ADHD may be considered a risk factor for sAD. Intriguingly, several overlaps have been shown between the two disorders, e.g., inflammatory activation, oxidative stress, glucose and insulin pathways, wingless-INT/mammalian target of rapamycin (Wnt/mTOR) signaling, and altered lipid metabolism. Indeed, Wnt/mTOR activities were found to be modified by MPH in several ADHD studies. Wnt/mTOR was also found to play a role in sAD and in animal models of the disorder. Moreover, MPH treatment in the MCI phase was shown to be successful for apathy including some improvement in cognition, according to a recent meta-analysis. In several AD animal models, ADHD-like behavioral phenotypes have been observed indicating a possible interconnection between ADHD and AD. In this concept paper, we will discuss the various evidence in human and animal models supporting the hypothesis in which ADHD might increase the risk for sAD, with common involvement of the Wnt/mTOR-pathway leading to lifespan alteration at the neuronal levels.

Abstract
Attention deficit hyperactivity disorder (ADHD) is a neurobehavioural disorder in children and adolescents. Although increases in oxidative stress and disturbances of neurotransmitter system such as the dopaminergic and abnormalities in several brain regions have been demonstrated, the pathophysiology of ADHD is not fully understood. Nevertheless, ADHD involves several factors that have been associated with an increase in neuroinflammation. This chapter presents an overview of factors that may increase neuroinflammation and play a potential role in the development and pathophysiology of ADHD. The altered immune response, polymorphisms in inflammatory-related genes, ADHD comorbidity with autoimmune and inflammatory disorders and prenatal exposure to inflammation are associated with alterations in offspring brain development and are a risk factor; genetic and environmental risk factors that may increase the risk for ADHD and medications can increase neuroinflammation. Evidence of an association between these factors has been an invaluable tool for research on inflammation in ADHD. Therefore, evidence studies have made it possible to generate alternative therapeutic interventions using natural products as anti-inflammatories that could have great potential against neuroinflammation in ADHD.

Abstract
Most mental disorders appear by age 14, but in most cases, they remain undiagnosed and untreated well into adulthood. A scoping review showed an absence of systematic reviews that address prevalence rates of mental disorders among children and adolescents in Europe that are based on community studies conducted between 2015 and 2020. To estimate the updated pooled prevalence of Anxiety Disorder, Depressive Disorder, Attention Deficit Hyperactivity Disorder (ADHD), Conduct Disorder (CD), Oppositional Defiant Disorder (ODD), Autism Spectrum Disorder, Eating Disorders, Substance Use Disorders (SUD), among children and adolescents living in Europe, a search strategy was conducted using MEDLINE, Embase and Psych Info and studies were also identified from reference lists and gray literature. Eligible studies were evaluated for reliability, validity, and bias. Trends of prevalence rates for each mental disorder were calculated. Almost one in five young people in Europe were found to suffer from a mental disorder, with a pooled prevalence rate of 15.5%. Anxiety disorders had the highest pooled prevalence rate (7.9% (95% CI 5.1-11.8%, I2: 98.0%)), followed by ADHD (2.9% (95% CI 1.2-6.9%, I2 = 94.3%)), ODD (1.9% (95% CI 1.0-3.7%, I2 = 98.4%)), depressive disorder (1.7% (95% CI 1.0-2.9%, I2 = 97.7%)), CD (1.5% (95% CI 0.6-3.8%, I2 = 98.8%)) and ASD (1.4% (95% CI 0.4-5.4%, I2 = 99.7%). No studies on SUD were identified. The mental health of children and adolescents may be improved by introducing routine screening, refining diagnostic sensitivity, raising awareness of mental disorders, minimizing stigma and socioeconomic inequality, as well as developing early intervention services. These facilitators of good mental health need to be prioritized, especially at a time of unprecedented risk factors for poor mental health.

The Role of Gut Dysbiosis in the Pathophysiology of Neuropsychiatric Disorders. Cells 2022; 12:cells12010054.

Abstract
Mounting evidence shows that the complex gut microbial ecosystem in the human gastrointestinal (GI) tract regulates the physiology of the central nervous system (CNS) via microbiota and the gut-brain (MGB) axis. The GI microbial ecosystem communicates with the brain through the neuroendocrine, immune, and autonomic nervous systems. Recent studies have bolstered the involvement of dysfunctional MGB axis signaling in the pathophysiology of several neurodegenerative, neurodevelopmental, and neuropsychiatric disorders (NPDs). Several investigations on the dynamic microbial system and genetic-environmental interactions with the gut microbiota (GM) have shown that changes in the composition, diversity and/or functions of gut microbes (termed "gut dysbiosis" (GD)) affect neuropsychiatric health by inducing alterations in the signaling pathways of the MGB axis. Interestingly, both preclinical and clinical evidence shows a positive correlation between GD and the pathogenesis and progression of NPDs. Long-term GD leads to overstimulation of hypothalamic-pituitary-adrenal (HPA) axis and the neuroimmune system, along with altered neurotransmitter levels, resulting in dysfunctional signal transduction, inflammation, increased oxidative stress (OS), mitochondrial dysfunction, and neuronal death. Further studies on the MGB axis have highlighted the significance of GM in the development of brain regions specific to stress-related behaviors, including depression and anxiety, and the immune system in the early life. GD-mediated deregulation of the MGB axis imbalances host homeostasis significantly by disrupting the integrity of the intestinal and blood-brain barrier (BBB), mucus secretion, and gut immune and brain immune functions. This review collates evidence on the potential interaction between GD and NPDs from preclinical and clinical data. Additionally, we summarize the use of non-therapeutic modulators such as pro-, pre-, syn- and post-biotics, and specific diets or fecal microbiota transplantation (FMT), which are promising targets for the management of NPDs.

Abstract
Knowledge of neurodevelopmental disorders such as attention deficit/hyperactivity disorder (ADHD), autism spectrum disorders (ASD) and intellectual disability (ID) in patients with esophageal atresia (EA) is scarce. The aims of this study were to investigate the prevalence and risk of ADHD, ASD and ID in individuals with EA. Data were obtained from four longitudinal population-based registries in Sweden and analyzed using Cox proportional hazards regression. Patients with EA born in Sweden in 1973-2018 were included together with five controls for each individual with the exposure matched on sex, gestational age at birth, birth year and birth county. Individuals with chromosomal aberrations and syndromes were excluded. In total, 735 individuals with EA and 3675 controls were included. Median age at time of the study was 20 years (3-48). ASD was found in 24 (3.9%), ADHD in 34 (5.5%) and ID in 28 (4.6%) individuals with EA. Patients with EA had a 1.66 times higher risk of ASD (95% confidence interval [CI], 1.05-2.64) and a 3.62 times higher risk of ID (95% CI, 2.23-5.89) compared with controls. The risk of ADHD was not significantly increased. ADHD medication had been prescribed to 88.2% of patients with EA and ADHD and to 84.5% of controls with ADHD. Individuals with EA have a higher risk of ASD and ID than individuals without the exposure. These results are important when establishing follow-up programs for children with EA to allow timely detection and consequentially an earlier treatment and support especially before school start.

Abstract
The aim of this study is to identify the psychosocial factors which are related with affiliate stigma in parents of children with ADHD through a systematic literature review. This review includes English publications from 2008 to 2022, which present the results of quantitative studies on the relationship between psychosocial factors and affiliate stigma in parents of children with ADHD. According to eligibility criteria, 7 articles were included in the review. The results showed that higher parental affiliate stigma is associated with lower parents’ psychosocial functioning (higher expressed depression, anxiety, lower self-esteem). It was also found that higher parental affiliate stigma is related to unfavorable behavior towards a child (higher expressed negativity/ less constructive parenting). The results also showed that higher parental affiliate stigma is associated with more expressed child's difficulties (ADHD symptoms/ internalizing and externalizing difficulties).

Abstract
Introduction: The aim was to examine the psychometric properties of the Polish version of the Adult ADHD Self-Report Scale (ASRS) among adolescents and adult working populations of different genders, the prevalence of ADHD, and its relationship to stress.
Materials and methods: A sample of 723 professionally active people and 1744 high school students participated in the study. Part A of the Adult ADHD Self-Report Scale (ASRS) was used to measure ADHD and the 4-item Perceived Stress Scale (PSS-4) was used to measure stress.
Results: Confirmatory factor analyses showed that the original 6-item two-factor solution of ASRS Part A had a satisfactory fit and showed basic measurement invariance between age groups and genders. Inattention and hyperactivity were related mostly similarly to stress in all groups. The prevalence of ADHD among adolescents was much higher than in previous reports, and no gender differences were found. About every fifth high school student and every tenth adult showed a risk of ADHD. The potential cause of the difference in the prevalence in the studied groups can be generation change.
Conclusions: ASRS is a well-functioning screening measure with good psychometric properties. It is a convenient option for large-scale epidemiological surveys necessary to understand potential generational changes in the prevalence of ADHD and the lack of gender differences among adolescents.

Abstract
OBJECTIVES Attention deficit hyperactivity disorder (ADHD) is a prevalent childhood disorder, but often goes unrecognised and untreated. To improve access to services, accurate predictions of populations at high risk of ADHD are needed for effective resource allocation. Using a unique linked health and education data resource, we examined how machine learning (ML) approaches can predict risk of ADHD. DESIGN Retrospective population cohort study. SETTING South London (2007-2013). PARTICIPANTS n=56 258 pupils with linked education and health data. PRIMARY OUTCOME MEASURES Using area under the curve (AUC), we compared the predictive accuracy of four ML models and one neural network for ADHD diagnosis. Ethnic group and language biases were weighted using a fair pre-processing algorithm. RESULTS Random forest and logistic regression prediction models provided the highest predictive accuracy for ADHD in population samples (AUC 0.86 and 0.86, respectively) and clinical samples (AUC 0.72 and 0.70). Precision-recall curve analyses were less favourable. Sociodemographic biases were effectively reduced by a fair pre-processing algorithm without loss of accuracy. CONCLUSIONS ML approaches using linked routinely collected education and health data offer accurate, low-cost and scalable prediction models of ADHD. These approaches could help identify areas of need and inform resource allocation. Introducing 'fairness weighting' attenuates some sociodemographic biases which would otherwise underestimate ADHD risk within minority groups.

Abstract
(1) Background: Recently, a growing number of studies have provided evidence to suggest a strong correlation between air pollution exposure and attention-deficit/hyperactivity disorder (ADHD). In this study, we assessed the relationship between early-life exposure to particulate matter (PM)10, PM2.5, and ADHD; (2) Methods: The National Health Insurance Research Database (NHIRD) contains the medical records, drug information, inspection data, etc., of the people of Taiwan, and, thus, could serve as an important research resource. Air pollution data were based on daily data from the Environmental Protection Administration Executive Yuan, R.O.C. (Taiwan). These included particulate matter (PM2.5 and PM10). The two databases were merged according to the living area of the insured and the location of the air quality monitoring station; (3) Results: The highest levels of air pollutants, including PM2.5 (adjusted hazard ratio (aHR) = 1.79; 95% confidence interval (CI) = 1.58-2.02) and PM10 (aHR = 1.53; 95% CI = 1.37-1.70), had a significantly higher risk of ADHD; (4) Conclusions: As such, measures for air quality control that meet the WHO air quality guidelines should be strictly and uniformly implemented by Taiwanese government authorities.

Abstract
The aim of our study was to assess the association between diet cost and attention deficit hyperactivity disorder (ADHD) in children. This study was a case-control study conducted in Isfahan, Iran. Based on the Diagnostic and Statistical Manual of Mental Disorders-V criteria, a total of 200 children aged 4-12 years with ADHD and 300 age- and sex-matched children without ADHD, respectively, participated in case and control groups. A validated food frequency questionnaire that contained 168 food items was used to assess the dietary intake. The cost of food items was obtained from licensed markets. The food price was corrected for edible portion sizes as well as food weight changes due to cooking process. Our results indicated that diet cost per 1000 kcal was significantly lower in the case group compared with the control group (60,843.48 ± 6987.83 vs. 67,828.33 ± 8989.48 Rials, p < .01). In the crude model, a significantly lower risk of ADHD was observed in the higher quartiles of diet cost per 1000 kcal (odds ratio (OR) = 0.06; 95% confidence interval (CI) = 0.03, 0.13; p < .001). This finding remained significant, even after adjustment for potential confounders such as age, gender, body mass index (BMI), socioeconomic status (SES), and intakes of eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and saturated fatty acids (SFA). Therefore, it seems that the risk of ADHD is inversely associated with diet cost in children. Further studies, particularly longitudinal ones, are warranted.
