Assessment of functioning in ADHD according to World Health Organization standards: First revision of the International Classification of Functioning, Disability and Health Core Sets.

AIM: To conduct the first revision of the World Health Organization International Classification of Functioning, Disability and Health (ICF) Core Sets for attention-deficit/hyperactivity disorder (ADHD). METHOD: A Delphi-like method was used, integrating evidence from stakeholder feedback and developing and piloting the ADHD ICF Core Set platform to inform revisions to the ADHD Core Sets. RESULTS: A total of 27 second-level ICF codes were added to the comprehensive ADHD Core Set: body functions of temperament and personality, and basic sensory functions; activities and participation in terms of learning to read and write, spoken communication, community life, religion and spirituality, education, economy, and human rights; environmental factors for domestic animals; and several societal services. The revised comprehensive Core Set contains 98 ICF codes: 18 body function codes; 47 activities and participation codes; and 33 environmental factor codes. Extensive changes were also made to the age-appropriate brief Core Sets to allow their independent use in research and clinical practice. INTERPRETATION: Although substantially expanded, the revised ICF Core Sets better reflect the lived experience of individuals with ADHD and clinical implementation preferences than the initial sets. We recommend further feasibility and validation studies of these Core Sets with the goal of optimizing their acceptance and practicability, and strengthening their evidence base.

An assessment of executive function in two different rat models of attention-deficit hyperactivity disorder: Spontaneously hypertensive versus Lphn3 knockout rats.

Attention-deficit/hyperactivity disorder (ADHD) a common neurodevelopmental disorder of childhood and often comorbid with other externalizing disorders (EDs). There is evidence that externalizing behaviors share a common genetic etiology. Recently, a genome-wide, multigenerational sample linked variants in the Lphn3 gene to ADHD and other externalizing behaviors. Likewise, limited research in animal models has provided converging evidence that Lphn3 plays a role in EDs. This study examined the impact of Lphn3 deletion (i.e., Lphn3-/- ) in rats on measures of behavioral control associated with externalizing behavior. Impulsivity was assessed for 30 days via a differential reinforcement of low rates (DRL) task and working memory evaluated for 25 days using a delayed spatial alternation (DSA) task. Data from both tasks were averaged into 5-day testing blocks. We analyzed overall performance, as well as response patterns in just the first and last blocks to assess acquisition and steady-state performance, respectively. "Positive control" measures on the same tasks were measured in an accepted animal model of ADHD-the spontaneously hypertensive rat (SHR). Compared with wildtype controls, Lphn3-/- rats exhibited deficits on both the DRL and DSA tasks, indicative of deficits in impulsive action and working memory, respectively. These deficits were less severe than those in the SHRs, who were profoundly impaired on both tasks compared with their control strain, Wistar-Kyoto rats. The results provide evidence supporting a role for Lphn3 in modulating inhibitory control and working memory, and suggest additional research evaluating the role of Lphn3 in the manifestation of EDs more broadly is warranted.

Quantified assessment of hyperactivity in ADHD youth using IR-UWB radar.

Research on the quantification of hyperactivity in youth with attention-deficit/hyperactivity disorder (ADHD) has been limited and inconsistent. The purpose of this study was to test the discriminative value of impulse-radio ultra-wideband (IR-UWB) radar for monitoring hyperactive individuals with ADHD and healthy controls (HCs). A total of 10 ADHD patients and 15 HCs underwent hyperactivity assessment using IR-UWB radar during a 22-min continuous performance test. We applied functional ANOVA to compare the mean functions of activity level between the 2 groups. We found that the mean function of activity over time was significantly different and that the activity level of the ADHD group slightly increased over time with high dispersion after approximately 7 min, which means that the difference in activity level between the two groups became evident at this period. Further studies with larger sample sizes and longer test times are warranted to investigate the effect of age, sex, and ADHD subtype on activity level function.

Metilfenidato e lisdexanfetamina para indivíduos com Transtorno do Déficit de Atenção com Hiperatividade / Methylphenidate and Lisdexamphetamine for Individuals with Attention Deficit Hyperactivity Disorder

INTRODUÇÃO: O TDAH é considerado uma condição do neurodesenvolvimento que se caracteriza por uma tríade de sintomas envolvendo desatenção, hiperatividade e impulsividade em um nível exacerbado e disfuncional para a idade. Os sintomas iniciam-se na infância, sendo capaz de persistir ao longo de toda a vida. Estas alterações ocorrem em diferentes contextos, podendo resultar em prejuízos afetivos, acadêmicos, ocupacionais, nas interações sociais e na qualidade de vida. O diagnóstico é feito com base em avaliação clínica e psicossocial completa. Geralmente, não são necessários exames de imagem ou laboratoriais para diagnóstico. Atualmente, o tratamento disponível no SUS é baseado em psicoterapias nas modalidades individual e em grupo. Entretanto, o tratamento medicamentoso pode ser necessário para o controle de sintomas e redução do impacto da doença nos diferentes domínios da vida do indivíduo. O objetivo do presente relatório é analisar as evidências científicas sobre o uso do metilfenidato (MPH) e da lisdexanfetamina (LDX) em paci

Children with attention-deficit/hyperactivity disorder spend more time in hyperconnected network states and less time in segregated network states as revealed by dynamic connectivity analysis.

Previous studies in children with attention-deficit/hyperactivity disorder (ADHD) have observed functional brain network disruption on a whole-brain level, as well as on a sub-network level, particularly as related to the default mode network, attention-related networks, and cognitive control-related networks. Given behavioral findings that children with ADHD have more difficulty sustaining attention and more extreme moment-to-moment fluctuations in behavior than typically developing (TD) children, recently developed methods to assess changes in connectivity over shorter time periods (i.e., "dynamic functional connectivity"), may provide unique insight into dysfunctional network organization in ADHD. Thus, we performed a dynamic functional connectivity (FC) analysis on resting state fMRI data from 38 children with ADHD and 79 TD children. We used Hidden semi-Markov models (HSMMs) to estimate six network states, as well as the most probable sequence of states for each participant. We quantified the dwell time, sojourn time, and transition probabilities across states. We found that children with ADHD spent less total time in, and switched more quickly out of, anticorrelated states involving the default mode network and task-relevant networks as compared to TD children. Moreover, children with ADHD spent more time in a hyperconnected state as compared to TD children. These results provide novel evidence that underlying dynamics may drive the differences in static FC patterns that have been observed in ADHD and imply that disrupted FC dynamics may be a mechanism underlying the behavioral symptoms and cognitive deficits commonly observed in children with ADHD.

Impact of COVID-19 outbreak on mental health and perceived strain among caregivers tending children with special needs.

BACKGROUND: While COVID-19 outbreak has had adverse psychological effects in children with special needs, the mental state and burden on their caregivers during this pandemic has yet to be reported. AIMS: The objectives of this study were to describe the mental health status and the change in perceived strain among caregivers during the COVID-19 outbreak. METHODS AND PROCEDURES: Two hundred sixty four caregivers completed an online survey that assessed demographics, use and perspective on tele-rehabilitation, homecare therapy, caregiver's strain and mental health. OUTCOMES AND RESULTS: The prevalence of depression, anxiety and stress symptoms were found to be 62.5 %, 20.5 % and 36.4 % respectively. A significant difference in caregiver strain (p <  0.001, effect size = 0.93) was observed during the outbreak compared to levels pre-outbreak (pre-outbreak strain was measured retrospectively). Caregivers not using tele-rehabilitation along with a perception of it being a poor medium for rehabilitation were at greater risks for poor mental health whereas a negative perception on homecare therapy were strongly associated with higher psychological symptoms and strain. CONCLUSIONS AND IMPLICATIONS: This study identified a high prevalence of depression and significant change in strain displayed by caregivers during the COVID-19 outbreak. We identified several factors associated with poor mental health and perceived strain that can be used to help safeguard caregivers.

Assessment of intraocular pressure, macular thickness, retinal nerve fiber layer, and ganglion cell layer thicknesses: ocular parameters and optical coherence tomography findings in attention-deficit/hyperactivity disorder

Objective: To compare intraocular pressure (IOP) and macular, retinal nerve fiber layer (RNFL), and ganglion cell layer (GCL) thicknesses in treatment-naive children with attention-deficit/hyperactivity disorder (ADHD), children with ADHD on regular methylphenidate (MPH) treatment for at least 3 months, and healthy controls. Methods: A total of 58 treatment-naive children with ADHD, 45 children with ADHD on regular MPH treatment, and 44 healthy controls were enrolled in this study. All participants underwent a comprehensive eye examination. Optical coherence tomography (OCT) was used to assess global RNFL thickness, central macular thickness, and GCL thickness in both eyes. Results: Separate univariate analysis of covariance (ANCOVA) on the outcome variables revealed a significant difference among the research groups with respect to IOP in the left eye. Post-hoc univariate analyses indicated that left IOP was significantly higher in children with ADHD under MPH treatment than among healthy controls. However, global RNFL thickness, central macular thickness, and GCL thickness of both eyes, as well as IOP in the right eye, were not significantly different across groups. Conclusion: Further longitudinal follow-up studies are needed to determine whether MPH treatment has any effect on IOP or OCT findings.

Brain Mapping Performance as an Occupational Therapy Assessment Aid in Attention Deficit Hyperactivity Disorder.

IMPORTANCE: Brain mapping performance (BMP) may provide strong predictors to analyze primary functional outcomes and support occupational therapy with clients with attention deficit hyperactivity disorder (ADHD). OBJECTIVE: To clarify the value of quantitative electroencephalography to indicate BMP in children with ADHD. DESIGN: One-year cross-sectional study. SETTING: Brain Computer Interface Laboratory, Mahidol University, Salaya, Nakhon Pathom, Thailand. PARTICIPANTS: Thai school-age children with and without ADHD (N = 305). OUTCOMES AND MEASURES: We used θ relative power in concordance with stepwise multiple regression analysis. Outcomes included measures of 12 brain locations that were compared between children with and without ADHD. RESULTS: Significant differences were found between the groups, especially for Cz, T3, Fp1, Fz, F4, and F7. According to BMP, the group with ADHD had higher emotional awareness and language comprehension than the group without ADHD. CONCLUSIONS AND RELEVANCE: Occupational therapy practitioners can use BMP as a valuable tool for setting occupational goals to help children with ADHD improve their social-emotional learning performance in school and in the community. BMP may provide an evaluation to support occupational therapy services for clients with ADHD. The result can be applied in clinical settings by quantitative electroencephalography training. WHAT THIS ARTICLE ADDS: BMP can be used as a neuropsychological and behavioral assessment tool for setting SMART (specific, measurable, attainable, relevant, and time-oriented) goals for occupational therapy services for clients with ADHD.

[Measurement of the theta / beta ratio with the quantified electroencephalogram in attention-deficit hyperactivity disorders]. / Valoración del cociente theta/beta en el electroencefalograma cuantificado de los trastornos por déficit de atención e hiperactividad.

Theta-Beta (T / B) ratio of the quantified electroencephalogram (EEGQ) in patients with attention deficit hyperactivity disorder (ADHD) constitutes a characteristic EEG variable of the primary disorder with an overall accuracy of 89%. The objective of this study was to measure the T/B ratio in a sample of patients with ADHD and the effects of the treatment with psychostimulants and non-psychostimulants on the T/B ratio. The sample consisted of 85 children between 6 and 18 years (68 males and 17 females) with the diagnosis of the inattentive and combined subtype of ADHD, according to the criteria of the DSM-V. An EEGQ was performed with measurement of the T/B ratio before and after 6 months of treatment with psychostimulant and non-psychostimulant drugs. Both groups were compared using the Wilcoxon signed range test for related samples. The results showed that 86% of the cases had a T/B ratio above the normal values for the age of them. The reduction in the T/B ratio was statistically significant in the group of patients treated with psychostimulants. The reduction of non-psychostimulants was not significant. In conclusion, we confirmed the high T/B ratio in patients with ADHD. Psychostimulant drugs decrease the elevated T/B ratio in patients with ADHD after 6 months of treatment.

EEG Theta/Beta Ratio Calculations Differ Between Various EEG Neurofeedback and Assessment Software Packages: Clinical Interpretation.

The quantitative electroencephalographic (QEEG) theta/beta power ratio (TBR) has been shown to have an association with attention-deficit hyperactivity disorder (ADHD), with a previous tacit assumption of equivalence across hardware and software systems. Therefore, the International Collaborative ADHD Neurofeedback (ICAN) randomized clinical trial used a fixed TBR ≥ 4.5 cutoff as measured by the Thought Technology Monastra-Lubar Assessment Suite as an inclusion criterion, 1.5 SD above norms collected with that system. However, a difference was noted between the TBR calculated by that assessment suite and the TBR computed by EEGer, the neurofeedback software used for treatment, leading us to investigate the discrepancy. The difference may arise from different calculation methods. This article explains and compares various computational methods used to calculate and display EEG values, including TBR, elucidating why the values are not equivalent across equipment and software programs. Two major sources of variance are (1) how "spectral leakage" at the ends of bands is handled and (2) whether voltages of bins within a band are first averaged and then squared to get bandwidth power or are first squared to get power (turning negative voltages into positive power) and then averaged to get the bandwidth power; the latter method results in higher band power. This article compares methods of computing the TBR. Biofeedback practitioners and investigators should be aware of the algorithms their systems use when interpreting TBRs and require normative comparison data collected with the same system.

Peer influence, Frontostriatal connectivity, and delay discounting in African American emerging adults.

Prior research has demonstrated the importance of delay discounting in adverse health behaviors, such as addiction, attention deficit hyperactivity disorder, risk taking, and obesity. Nevertheless, the functional connectivity of neural circuitry associated with delay discounting and the ways in which the social environment may influence frontostriatal connectivity remain largely unknown, particularly in African Americans. Building on recent literature implicating frontostriatal connectivity during active delay discounting decision making and at rest, we used functional magnetic resonance imaging to assess the association between delay discounting and frontostriatal resting state connectivity (rsFC). We also examined the capacity of social relationships with parents and peers to longitudinally predict frontostriatal rsFC. The study cohort was composed of 91 rural African American emerging adults followed over a 6-year period. Greater (i.e., more positive) frontostriatal rsFC was associated with decreased delay discounting (i.e., less impulsive decision making). In addition, peer relationships at ages 20 and 21 significantly predicted frontostriatal rsFC at age 25 above and beyond parental influence. A significant indirect effect of peer affiliation on delay discounting through frontostriatal rsFC also emerged. These results indicate a role of frontostriatal connectivity in delay discounting decision making and highlight peers' unique influence on decision making behaviors through frontostriatal rsFC during emerging adulthood.

Initial development of an attention-deficit/hyperactivity disorder visual analog scale for rapid assessment of medication effects.

Attention-deficit/hyperactivity disorder (ADHD) is a commonly occurring neurodevelopmental disorder in children and young adults. If under or inadequately treated, long-term morbidity, mortality, increased social, and health care costs may follow. Standardized assessment tools aid in accurate diagnosis and ongoing treatment modifications; however, they are underused by providers at follow-up visits. This article discusses the development of an assessment tool, presents initial data on the use of a nonstandardized visual analog scale (VAS), and re-emphasizes the importance of regular inclusion of standardized rating scales during periodic reassessments. A targeted literature search of PubMed, Articles+, ERIC, CINAHL, and Google Scholar was performed and findings were reported. An interview with the developer was conducted along with a chart review comparing those using and not using the VAS. The use of the VAS may improve appointment efficiency and result in more thorough symptom assessment. Introduction of the VAS may remind providers of the importance of using standardized tools to reassess all ADHD symptoms regularly. Furthermore, the need for practice efficiency highlights the value of standardization of this VAS.

Autism spectrum disorder polygenic scores are associated with every day executive function in children admitted for clinical assessment.

Autism spectrum disorder (ASD) and other neurodevelopmental disorders (NDs) are behaviorally defined disorders with overlapping clinical features that are often associated with higher-order cognitive dysfunction, particularly executive dysfunction. Our aim was to determine if the polygenic score (PGS) for ASD is associated with parent-reported executive dysfunction in everyday life using the Behavior Rating Inventory of Executive Function (BRIEF). Furthermore, we investigated if PGS for general intelligence (INT) and attention deficit/hyperactivity disorder (ADHD) also correlate with BRIEF. We included 176 children, adolescents and young adults aged 5-22 years with full-scale intelligence quotient (IQ) above 70. All were admitted for clinical assessment of ASD symptoms and 68% obtained an ASD diagnosis. We found a significant difference between low and high ASD PGS groups in the BRIEF behavior regulation index (BRI) (P = 0.015, Cohen's d = 0.69). A linear regression model accounting for age, sex, full-scale IQ, Social Responsiveness Scale (SRS) total score, ASD, ADHD and INT PGS groups as well as genetic principal components, significantly predicted the BRI score; F(11,130) = 8.142, P < 0.001, R2 = 0.41 (unadjusted). Only SRS total (P < 0.001), ASD PGS 0.1 group (P = 0.018), and sex (P = 0.022) made a significant contribution to the model. This suggests that the common ASD risk gene variants have a stronger association to behavioral regulation aspects of executive dysfunction than ADHD risk or INT variants in a clinical sample with ASD symptoms. Autism Res 2020, 13: 207-220. © 2019 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: People with autism spectrum disorder (ASD) often have difficulties with higher-order cognitive processes that regulate thoughts and actions during goal-directed behavior, also known as executive function (EF). We studied the association between genetics related to ASD and EF and found a relation between high polygenic score (PGS) for ASD and difficulties with behavior regulation aspects of EF in children and adolescents under assessment for ASD. Furthermore, high PGS for general intelligence was related to social problems.

Children's Color Trail Test for Objective Assessment of Attention in Children with Attention Deficit Hyperactivity Disorder: A Diagnostic Accuracy Study.

OBJECTIVE: To compare the Children's Color Trail Test scores in children with and without Attention Deficit Hyperactivity Disorder to assess its diagnostic performance in assessing attention-deficit. METHODS: 50 children with Attention Deficit Hyperactivity Disorder (diagnosed as per Diagnostic and Statistical Manual, 5th edition) and 50 age- and sex-matched children underwent Test 1 and Test 2 of the Children's Color Trail Test. A Receiver Operating Characteristics curve was constructed for the diagnostic accuracy of Children's Color Trail Test in Attention Deficit Hyperactivity Disorder. RESULTS: The Receiver Operating Characteristics curve showed a score ≤32 for Children's Color Trail Test 1 [AUC: 0.8 (0.71 to 0.87); P<0.001] and score ≤40 for Children's Color Trail Test 2 [AUC: 0.85 (0.77 to 0.92); P<0.001] as the best cut-off for diagnosing Attention Deficit Hyperactivity Disorder. CONCLUSIONS: Children's Color Trail Test is a promising tool for diagnosing attention deficit, and could be used in settings where parent or teacher reports are not available.

Children with Attention-Deficit/Hyperactivity Disorder Perform Differently on Pediatric Concussion Assessment.

OBJECTIVE: To compare Child Sport Concussion Assessment Tool Fifth Edition (Child SCAT5) performance between uninjured children with attention-deficit/hyperactivity disorder (ADHD) and precisely matched controls without ADHD. STUDY DESIGN: A nested case-control study was conducted within a cohort of middle school athletes (age 11-12 years) who completed preseason testing. Students with ADHD were individually matched to students without ADHD based on age, sex, language spoken at home, number of prior concussions, sport, and school they attended. The final sample included 54 students (27 with ADHD and 27 controls), 38 (70.4%) boys and 16 (29.6%) girls (average age: 11.7 years, SD = 0.5). RESULTS: Children with ADHD reported more symptoms (M = 13.33, SD = 5.69, P < .001) and greater symptom severity (M = 22.59, SD = 1 1.60, P < .001) compared with controls (total symptoms: M = 6.44, SD = 4.96; symptom severity: M = 8.04, SD = 6.36). Children with ADHD performed similarly to controls on the Child SCAT5 cognitive tests. Children with ADHD committed 3 times as many total balance errors (median = 6) than children without ADHD (median = 2) and committed twice as many errors on single leg stance (ADHD median = 4; No ADHD median = 2) (P values < .001). CONCLUSIONS: Children with ADHD endorsed more concussion-like symptoms and performed worse on balance testing during preseason Child SCAT5 assessment compared with matched controls without ADHD. These findings highlight the challenges of interpreting Child SCAT5 performance in children with ADHD following a concussion or suspected concussion and illustrate the value of administering the measure to children to document their pre-injury performance.

Financial decision-making in adults with ADHD.

OBJECTIVE: Attention-deficit/hyperactivity disorder (ADHD) in adulthood is associated with problems in multiple domains of everyday life, including financial decision-making (FDM). Research on FDM in adults with ADHD is, however, limited and FDM has never been examined in an objective standardized manner in these patients. The aim of the present study is to explore FDM abilities of adults with ADHD, using both subjective and standardized objective measures. METHOD: Adults with ADHD (n = 45) and healthy controls (n = 51) completed a comprehensive test battery, including an evaluation of their personal financial situation, a neuropsychological assessment and standardized tests and questionnaires measuring various aspects of FDM. RESULTS: Adults with ADHD reported to have a significantly poorer financial situation than healthy controls, including having less income, more often debts and less often a savings account. Furthermore, adults with ADHD showed significantly lower scores than healthy controls in standardized tests measuring financial competence and capacity (i.e., understanding bank statements/protocols and evaluating financial problems) as well as in a test measuring decision making with implications for the future. Furthermore, compared with healthy controls, adults with ADHD reported more often to buy on impulse and to use an avoidant or spontaneous decision-making style. A mediating effect of numeracy was found for 2 measures of FDM (i.e., financial competence and capacity); however, group differences on these measures remained statistically significant. CONCLUSIONS: Adults with ADHD have difficulties with several aspects of FDM. These difficulties may at least partly explain the poorer financial situation of adults with ADHD.

Risk-Taking Behavior in Attention Deficit/Hyperactivity Disorder (ADHD): a Review of Potential Underlying Mechanisms and of Interventions.

PURPOSE OF REVIEW: Attention deficit/hyperactivity disorder (ADHD) is associated with several forms of risk-taking behavior (RTB). This paper aims to examine the scope of ADHD-related RTB, to highlight potential underlying mechanisms of this association, and to review initial evidence for interventions aimed to treat ADHD-related RTB. RECENT FINDINGS: Multiple lines of evidence indicate that ADHD is associated with real-life RTB across several domains (e.g., reckless driving, substance use, and unprotected sex), which is corroborated by evidence on laboratory risk-taking tasks. Several individual differences, some of them informed by decision theory, e.g., comorbid disorders, parental monitoring, and perceived enlarged benefits of RTB, may explain the link between ADHD and RTB. A number of studies showed that interventions designed for ADHD may reduce RTB. ADHD is linked to RTB across several domains. Decision theory may serve as a conceptual framework for understanding the underlying mechanisms, and thus may inform future research.

Practitioner Review: Assessment and treatment of preschool children with attention-deficit/hyperactivity disorder.

BACKGROUND: Attention-deficit/hyperactivity disorder (ADHD) often emerges during the preschool years and remains impairing throughout the life span. Early identification and intervention may yield lasting benefits that alter the often-adverse trajectory of the disorder. METHODS: This Practitioner Review provides up-to-date information regarding the evaluation and treatment of ADHD in preschool children. The clinical presentation of ADHD in preschool children, its persistence into later childhood, the applicability of DSM-5 criteria for preschoolers with ADHD, and early predictors of long-term trajectories are addressed, as well as current findings from randomized controlled trials of both nonpharmacological and pharmacological interventions. RESULTS: Symptoms of hyperactivity/impulsivity extend down to age 3, but several inattention symptoms, as defined by DSM-V, less accurately differentiate preschoolers with and without ADHD. Most preschool youth with ADHD symptoms continue to manifest symptoms and impairment into school-age and adolescence. However, few predictors of persistence beyond early severity have been identified. Behavioral interventions constitute a first-line treatment for preschool ADHD symptoms, with telepsychiatry increasing in prominence to help to mitigate financial, geographic, and/or logistical barriers to care. Pharmacological interventions, particularly psychostimulants, also confer demonstrable benefits, yet efficacy and safety profiles are less desirable relative to findings in school-age youth. CONCLUSIONS: Acute treatments have demonstrable efficacy, but do not appear to fundamentally alter underlying mechanisms or long-term trajectories.
