Diverse parents inform stages of care for youth ADHD treatment, engagement

Seeking the perspectives of parents of racial/ethnic minority youth with attention deficit hyperactivity disorder (ADHD) to better understand what could be done to improve access and treatment engagement, Boston Medical Center researchers have developed a new framework of six stages, which they say could be used to design family‐centered interventions.

Attention-deficit/hyperactivity disorder in youth with psychosis spectrum symptoms

BackgroundChildhood attention deficit-hyperactivity disorder (ADHD) is common in psychotic disorders. However, prevalence estimates vary widely and the impact of ADHD on the severity of psychotic symptoms and associated features is unclear. We used the Philadelphia Neurodevelopmental Cohort (PNC; n = 9498 youth age 8–21), which includes a comprehensive structured interview of clinical symptoms and the Penn Computerized Neurocognitive Battery (CNB), to clarify the prevalence of ADHD in psychosis spectrum (PS) youth and determine if comorbid ADHD is associated with severity of psychotic symptoms and cognitive impairment. MethodsPrevalence of ADHD among PS youth was established by comparing PS youth to all other youth in the PNC cohort. Cognition was compared between four groups: typically developing (TD), ADHD, PS without ADHD (PS-ADHD), and PS with ADHD (PS+ADHD). To evaluate the impact of ADHD on psychosis symptomatology, severity of positive and negative psychotic symptoms was compared between PS-ADHD and PS+ADHD groups. ResultsADHD was more prevalent in PS youth compared to non-PS youth (45% vs. 20%). Cognition was significantly impaired in PS youth compared to TD youth, but the presence of ADHD in PS youth was not associated with greater cognitive impairment. Co-morbid ADHD was, however, associated with more severe psychosis symptoms in PS youth. ConclusionADHD is more common among PS youth compared to youth without PS symptoms and is associated with more severe psychotic symptoms, but not severity of cognitive impairment. The association between ADHD and psychotic disorders may be mediated by psychosis symptoms in youth and may manifest a more stable cognitive impairment.

ADHD and epilepsy-related QoL in youth with epilepsy

ObjectivePediatric epilepsy and attention-deficit/hyperactivity disorder (ADHD) present a cumulative vulnerability to youth, particularly in the domains of executive function (EF) and quality of life (QoL). The aim of this study was to explore the relationships between EF and epilepsy-specific QoL in youth with epilepsy (YWE) who also have ADHD. MethodsYouth with epilepsy aged 5–18 years and caregivers participated in a large multi-site national validation of the PedsQL™ Epilepsy Modules. YWE and their caregivers were asked to complete measures of epilepsy-specific QoL, ADHD symptoms, and EF. Previous ADHD diagnosis was reported by caregivers as well as abstracted from the medical record. ResultsCaregiver and YWE reports of current ADHD symptoms significantly predicted all epilepsy-specific QoL domains. Suboptimal QoL was reported for those YWE whose ADHD symptoms were above the clinical threshold compared to YWE whose ADHD symptoms were within the average range. Results were similar for YWE with a documented ADHD vs no ADHD diagnosis. In addition, poorer metacognition and behavioral regulation EF was associated with lower epilepsy-specific QoL for both YWE with ADHD and without ADHD diagnosis. However, in YWE with ADHD, effect sizes were consistently larger for behavioral regulation compared to metacognition across epilepsy-specific QoL domains, with behavioral regulation accounting for 50% of the variance in each of the EF and mood QoL domains. SignificanceAddressing ADHD symptoms, epilepsy-specific, QoL, and EF as part of routine epilepsy care may promote optimal outcomes for YWE with ADHD as well as relieve burden on the healthcare system.

Adding the missing voice: How self-report of autistic youth self-report on an executive functioning rating scale compares to parent report and that of youth with attention deficit hyperactivity disorder or neurotypical development.

Executive functions are often impaired in autistic people and relate to important outcomes such as mental health, success in school and work, and quality of life. Evaluating executive functions helps autistic people, clinicians, and families identify targets for external supports and skill building. Youth self-report of executive function has not been studied, yet we know that self-report from autistic youth is key to understanding other cognitive/behavioral phenomena in autism such as anxiety, obsessions/compulsions, sensory sensitivities, and repetitive behaviors. We investigated self- and parent-report of executive function problems in 197 autistic youth without intellectual disability (ages 11-18 years), including the magnitude and profiles of executive function problems autistic youth report across subdomains of executive function. We compared autistic self-report with that of 114 youth with attention deficit hyperactivity disorder without intellectual disability and 197 neurotypical youth. We found that autistic youth report significant executive function problems compared to neurotypical youth and a distinctive profile of challenges in comparison to attention deficit hyperactivity disorder youth. Parents and their autistic children diverged regarding the magnitude of the youth's executive function difficulties, but both identify inflexibility as the most impaired executive function subdomain. Autistic youth and their parents were somewhat more concordant in their report of executive function problems than youth with attention deficit hyperactivity disorder and their parents, but only showed moderate concordance at best. These findings elevate the importance of asking autistic youth directly about their executive functioning when engaging them in assessment and intervention, or researching executive functions in autism.

The Relationship Between Emotional Intelligence and Parenting Stress in Mothers of Children With Attention Deficit Hyperactivity Disorder

Background: Attention-deficit/ hyperactivity disorder (ADHD) is one of the most common psychiatric disorders in children and adolescents. Parents of these youth experience more parenting stress. Emotional Intelligence (EI) has a very close relationship with mental health. Objective: This study aimed to investigate the relationship between EI and parenting stress in mothers of ADHD youth. Methods: This cross-sectional study was conducted on 136 mothers of ADHD children and adolescents under treatment in the Gil specialized consulting center of Rasht City. Demographic questionnaire, PSI-SF parenting stress questionnaire, and Shearing emotional intelligence questionnaire were used to evaluate the participants. Comorbidities extracted from the patient files, based on the diagnosis of child and adolescent psychiatrists. Data were analyzed using SPSS v. 22 by mean, percentage, standard deviation, and Pearson correlation coefficient. Results: The relationship between the mothers' mean EI and parenting stress scores were not significant with the age, grade of education, duration of the treatment, and the comorbidities in children (P>0.05). There was a meaningful relationship between the components of EI (P<0.05) and the total score of EI with parenting stress scores (P= 0.001, r= -0.42). Higher emotional intelligence is associated with a lower parenting stress score. Conclusion: Mothers of ADHD youth who had higher EI had less parenting stress.

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.

Overdiagnosis of Attention-Deficit/Hyperactivity Disorder in Children and Adolescents

Reported increases in attention-deficit/hyperactivity disorder (ADHD) diagnoses are accompanied by growing debate about the underlying factors. Although overdiagnosis is often suggested, no comprehensive evaluation of evidence for or against overdiagnosis has ever been undertaken and is urgently needed to enable evidence-based, patient-centered diagnosis and treatment of ADHD in contemporary health services. To systematically identify, appraise, and synthesize the evidence on overdiagnosis of ADHD in children and adolescents using a published 5-question framework for detecting overdiagnosis in noncancer conditions. This systematic scoping review adhered to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) Extension for Scoping Reviews and Joanna Briggs Methodology, including the PRISMA-ScR Checklist. MEDLINE, Embase, PsychINFO, and the Cochrane Library databases were searched for studies published in English between January 1, 1979, and August 21, 2020. Studies of children and adolescents (aged ≤18 years) with ADHD that focused on overdiagnosis plus studies that could be mapped to 1 or more framework question were included. Two researchers independently reviewed all abstracts and full-text articles, and all included studies were assessed for quality. Of the 12 267 potentially relevant studies retrieved, 334 (2.7%) were included. Of the 334 studies, 61 (18.3%) were secondary and 273 (81.7%) were primary research articles. Substantial evidence of a reservoir of ADHD was found in 104 studies, providing a potential for diagnoses to increase (question 1). Evidence that actual ADHD diagnosis had increased was found in 45 studies (question 2). Twenty-five studies showed that these additional cases may be on the milder end of the ADHD spectrum (question 3), and 83 studies showed that pharmacological treatment of ADHD was increasing (question 4). A total of 151 studies reported on outcomes of diagnosis and pharmacological treatment (question 5). However, only 5 studies evaluated the critical issue of benefits and harms among the additional, milder cases. These studies supported a hypothesis of diminishing returns in which the harms may outweigh the benefits for youths with milder symptoms. This review found evidence of ADHD overdiagnosis and overtreatment in children and adolescents. Evidence gaps remain and future research is needed, in particular research on the long-term benefits and harms of diagnosing and treating ADHD in youths with milder symptoms; therefore, practitioners should be mindful of these knowledge gaps, especially when identifying these individuals and to ensure safe and equitable practice and policy.

Ecological contexts of youth antisocial behaviors: A longitudinal perspective.

The current study examined and compared the relative influence of ecological factors on youth antisocial behaviors (i.e., aggression and rule-breaking) using longitudinal datawhile assessing the moderating effect of youth attention-deficit/hyperactivity disorder (ADHD) diagnosis. The study used the fifth and sixth wave of data from the Fragile Families and Child Wellbeing Study (n = 2595; mean age = 9.26 at wave five) for the analysis. Multivariate models show that youth ADHD, physically and psychologically abusive parenting, peer victimization, and community cohesion were important predictors of youth antisocial behaviors. Furthermore, youth ADHD diagnosis moderated some associations between the ecological factors and antisocial behaviors, suggesting that youth with and without ADHD may respond to some ecological contexts differently regarding the concerningbehaviors. The findings imply that interventions targeting youth antisocial behaviors should involve collaboration across systems and coordination across programs to tackle a multilayered ecological context, especially when youth with ADHD are involved.

Proposing and Validating the Diagnosis Scale for Internet Gaming Disorder in Taiwanese ADHD Adolescents: Likert Scale Method Based on the DSM-5.

The paper aims to adjust the Taiwanese version of Internet gaming disorder-short form Likert scale with Likert (IGD-SF-T-L) based on the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) criteria to a Likert scale model and test its psychometric property among children and adolescents with Attention Deficit Hyperactivity Disorder (ADHD). Confirmatory factor analysis (CFA) was conducted for validity and the Cronbach’s α for reliability of IGD-SF-T-L. The ROC (receiver operating curves) was used to propose the cut-off point for assessing the instrument’s psychometric properties and its corresponding indices for the diagnostic accuracy. In total, 102 children and adolescents with ADHD were recruited. The construct validity of IGD-SF-T by CFA was model well fitted with excellent reliability (Cronbach’s α = 0.918). The ROC using the Chen’s CIAS > 56 as the state variable for IGD diagnosis showed the AUC (areas under the curves) was 0.918. The cut-off point proposed for IGD-SF-T-L to indicate a diagnosis of IGD was ≥ 10. The corresponding indices of accuracy: sensitivity, specificity, LR (likelihood ratio) +, LR-, and AUC were 0.893, 0.826, 5.134, 0.130, and 0.859, respectively. The proposed IGD-SF-T-L is an adequate, standardized psychometrical measurement for diagnosing IGD among Taiwanese adolescents with ADHD. More attention should be paid toward recent ADHD youth with Internet gaming disorder and their family.

Tracking Inhibitory Control in Youth With ADHD: A Multi-Modal Neuroimaging Approach.

BackgroundA decreased ability to inhibit a speeded motor response is a well-studied deficit in Attention Deficit Hyperactivity Disorder (ADHD), and has been proposed as an endophenotype. Inhibitory control has been assessed reliably with the Stop Signal Task (SST) and is associated with prior documented differences in regional brain function using f-MRI. Here, we advance on these findings by examining their structural connectivity and white matter integrity with the goal of identifying a network underlying a core cognitive deficit in ADHD.MethodsHealthy controls (N=16) and youth diagnosed with ADHD (N=60) were recruited through the Province of Ontario Neurodevelopmental Disorders Network (POND) and the Hospital for Sick Children. An f-MRI activation difference map was co-registered with each participant’s white matter imaging data, representing the specific network nodes where ADHD youth diverged significantly from controls while performing the SST. Probabilistic tractography was applied from these nodes, and white matter integrity indices such as fractional anisotropy (FA) within the tracts of interest were contrasted between the groups and correlated with SST output measures, including the measure of inhibitory control, the stop signal reaction time (SSRT).ResultsThe tracts that connected the network nodes belonged primarily to the inferior fronto-occipital fasciculus (IFOF) and cingulum. ADHD subjects showed trend differences in FA compared to controls between right inferior frontal gyrus (IFG) and right superior temporal gyrus (P= 0.09), right IFG and right posterior cingulate (P= 0.01), right anterior cingulate to posterior cingulate (p= 0.08), and between left middle temporal gyrus (BA 39) and left posterior cingulate (P=0.02). A trend correlation was found between radial diffusivity within IFG to STG white matter (IFOF) and SSRT.ConclusionsWe identified potential white matter tracts related to deficient inhibitory control, elucidating the brain mechanisms of an important cognitive deficit in ADHD. These findings could be integrated into future endophenotypic biomarker studies, incorporating altogether brain structure, function, and behavior for future studies of ADHD and other psychiatric conditions that exhibit this deficit.

Maternal Emotion Dysregulation Predicts Emotion Socialization Practices and Adolescent Emotion Lability: Conditional Effects of Youth ADHD Symptoms.

Maternal emotional functioning and emotion socialization practices can facilitate or hinder children's emotional development, and youth with symptoms of attention-deficit/hyperactivity disorder (ADHD) are at increased risk for emotion lability. However, little is known about the independent and interactive effects of maternal emotion dysregulation and adolescent ADHD symptoms on maternal emotion socialization and adolescent emotion lability over time. Using secondary data analyses of a longitudinal community sample of youth and their mothers (Nbaseline = 247; 43.7% female), the current study examined direct and indirect effects of maternal emotion dysregulation on adolescent emotion lability via supportive and non-supportive emotion socialization practices as mediators, and the extent to which adolescent ADHD symptoms moderated these longitudinal pathways. Mothers reported on all study constructs. Results showed that non-supportive parenting responses to adolescents' negative emotional expressions partially mediated the association between maternal emotion dysregulation and adolescent emotion lability, and the effect was stronger at higher levels of youth ADHD symptom severity. Results suggest that parent- and youth-level characteristics interact to confer risk for non-supportive emotion socialization practices and adolescent emotion lability. This research contributes uniquely to theory and research on ADHD and emotional functioning across adolescence. Future research should extend this work by utilizing multi-modal assessment.

Cortisol, inflammatory biomarkers and neurotrophins in children and adolescents with attention deficit hyperactivity disorder (ADHD) in Taiwan

BackgroundHypothalamus-Pituitary-Adrenal (HPA) axis dysregulation, inflammation and imbalance of neurotrophins have been suggested in attention deficit hyperactivity disorder (ADHD), but the results have not been conclusive. The aim of this study is to investigate the levels of salivary cortisol across 4-time points during the day, and of morning plasma inflammatory biomarkers and neurotrophins, in youth with ADHD and in typically developing youth (TD), with stratification by age, ADHD subtypes and oppositional defiant disorder (ODD) comorbidity in Taiwan. MethodsWe conducted a case-control study measuring saliva cortisol levels at 4 different time points during the day (at awakening, noon, 1800 h and bedtime) and morning plasma levels of inflammatory and neurotrophins biomarkers in youth with ADHD (n = 98, age 6–18 years old with mean age 9.32 ± 3.05 years) and TD (n = 21, age 6–18 years old with mean age 9.19 ± 2.96 years) in Taiwan. ResultsOur study showed that youth with ADHD had lower levels of bedtime salivary cortisol (effects size (ES) = −0.04, p = .023), with children with the combined form of the disorder (with inattention, hyperactivity and impulsivity all present) having the lowest awakening salivary cortisol levels. ADHD youth also had higher levels of plasma high-sensitivity C-reactive protein (hs-CRP) and interleukin (IL)-6 (ES = 0.85–1.20, p < .0001), and lower plasma tumor necrosis factor-alpha (ES = −0.69, p = .009) and brain-derived neurotrophic factors (BDNF) (ES = −1.13, p < .0001). Both ADHD groups regardless of ODD comorbidity had higher levels of IL-6 (p < .0001) and lower levels BDNF (p < .0001). ConclusionThe lower bedtime salivary cortisol levels and higher levels of inflammatory biomarkers in youth with ADHD further support the role of abnormal HPA axis and inflammation in ADHD. Moreover, the lower levels of BDNF in ADHD also indicate that BDNF may be a potential biomarker in this disorder that is part of a broader biological dysfunction.

Treatment Efficacy of Internet Gaming Disorder With Attention Deficit Hyperactivity Disorder and Emotional Dysregulaton.

BackgroundRecent youth with Attention Deficit Hyperactivity Disorder (ADHD) noticed emotional dysregulation if they had Internet Gaming Disorder (IGD). This study aims to understand the treatment efficacy of IGD with ADHD and emotional dysregulaton.MethodA total of 101 ADHD youths were recruited. We used the Chen Internet Addiction Scale and IGD criteria of the diagnotsic statistical manual (DSM)-5 to confirm IGD. The Swanson, Nolan, and Pelham questionnaire Version IV was used for symptoms of ADHD and oppositional defiant disorder. Disruptive mood dysregulation disorder was assessed by psychiatrist.ResultsThere is a new phenomenon that emotional dysregulation has been frequently noticed in severely gaming-addicted ADHD youth. Treatment efficacy of IGD is good when the underlying symptom of ADHD is controlled. Symptom scores of disruptive mood dysregulation (DMDD) were significantly reduced by 71.9%, 74.8%, and 84.4% at week 2, 3, and 4, respectively (P ≤ .001) after adjusting baseline symptom severity.ConclusionIGD may strongly arouse emotional dysregulation. Future DSM criteria could consider these gaming-addicted youth as a specific subclass of ADHD.

Effects of the dopamine transporter gene on striatal functional connectivity in youths with attention-deficit/hyperactivity disorder.

The dopamine transporter gene (DAT1), striatal network dysfunction, and visual memory deficits have been consistently reported to be associated with attention-deficit/hyperactivity disorder (ADHD). This study aimed to examine the effects of the DAT1 rs27048 (C)/rs429699 (T) haplotype on striatal functional connectivity and visual memory performance in youths with ADHD. After excluding those who had excessive head motion, a total of 96 drug-naïve youths with ADHD and 114 typically developing (TD) youths were assessed with the resting-state functional magnetic resonance imaging and the delayed matching to sample (DMS) task for visual memory. We examined the effects of ADHD, DAT1 CT haplotype, and the ADHD × CT haplotype interaction on the functional connectivity of five striatal seeds. We also correlated visual memory performance with the functional connectivity of striatal subregions, which showed significant diagnosis × genotype interactions. Compared with TD youths, ADHD youths showed significant hypoconnectivity of the left dorsal caudate (DC) with bilateral sensorimotor clusters. Significant diagnosis × genotype interactions were found in the connectivity between the left DC and the right sensorimotor cluster, and between the right DC and the left dorsolateral prefrontal/bilateral anterior cingulate clusters. Furthermore, the connectivity of the left DC showing significant diagnosis × genotype interactions was associated with DMS performance in youths with ADHD who carried the DAT1 CT haplotype. A novel gene-brain-behavior association between the left DC functional connectivity and visual memory performance in ADHD youths with the DAT1 rs27048 (C)/rs429699 (T) haplotype suggests a differential effect of DAT1 genotype altering specific brain function causing neuropsychological dysfunction in ADHD.

Inter-hemispheric Asymmetry Patterns in the ADHD Brain: A Neuroimaging Replication Study.

Attention-deficit/ hyperactivity disorder (ADHD) is the most common neurodevelopment disorder in children, and many genetic markers have been linked to the behavioral phenotypes of this highly heritable disease. The neuroimaging correlates are similarly complex, with multiple combinations of structural and functional alterations associated with the disease presentations of hyperactivity and inattentiveness. Thus far, neuroimaging studies have provided mixed results in ADHD patients, particularly with respect to the laterality of findings. It is possible that hemispheric asymmetry differences may help reconcile the variability of these findings. We recently reported that inter-hemispheric asymmetry differences were more sensitive descriptors for identifying differences between ADHD and typically developing (TD) brains (n=849) across volumetric, morphometric, and white matter neuroimaging metrics. Here, we examined the replicability of these findings across a new data set (n=202) of TD and ADHD subjects at the time of diagnosis (medication naive) and after a six week course of either stimulant drugs, non-stimulant medications, or combination therapy. Our findings replicated our earlier work across a number of volumetric and white matter measures confirming that asymmetry is more robust at detecting differences between TD and ADHD brains. However, the effects of medication failed to produce significant alterations across either lateralized or symmetry measures. We suggest that the delay in brain volume maturation observed in ADHD youths may be hemisphere dependent. Future work may investigate the extent to which these inter-hemispheric asymmetry differences are causal or compensatory in nature.

Functional Impairment in Youth With ADHD: Normative Data and Norm-Referenced Cutoff Points for the Before School Functioning Questionnaire and the Parent Rating of Evening and Morning Behavior Scale, Revised.

Children with attention-deficit/hyperactivity disorder (ADHD) frequently manifest behavioral difficulties in the morning prior to school and in the afternoons and evenings. We sought to establish norms for 2 time-specific measures of functioning: the Before School Functioning Questionnaire (BSFQ) and the Parent Rating of Evening and Morning Behavior Scale, Revised (PREMB-R), which includes Morning (AM) and Evening (PM) subscales. The normative online survey of a representative US sample of 1,200 primary caregivers of children and adolescents aged between 6 and 17 years was conducted in June 2016. A quota system was used whereby caregivers of 50 male and 50 female children or adolescents were recruited in each age group, ie, 100 parents for each of the 12 age groups. Diagnosis of ADHD relied on a caregiver's report that his or her child was so diagnosed by a health professional. Across all items of the BSFQ, youth with current untreated ADHD or a history of ADHD were rated as more severely ill than those without ADHD (all unadjusted P values < .001), even after adjustment for psychiatric comorbidity (all adjusted P values < .001). A similar pattern was observed for the PREMB-R AM (all unadjusted P values < .001; all adjusted P values < .001, except for item 1 [P = .01]) and PREMB-R PM (all unadjusted P values < .001; all adjusted P values < .001). The use of a large population sample allowed for computation of age-stratified norms for 4 thresholds of risk: screening risk (80th percentile), mild functional impairment (90th percentile), moderate functional impairment (93rd percentile), and severe functional impairment (98th percentile). The norms generated by this study can guide clinicians in the use of the BSFQ and PREMB-R for identifying those ADHD youth who may be experiencing difficulties in the early morning and late afternoon/evening. Such tools are needed given the availability of treatments that can target ADHD symptoms and impairments at these extremes of the daily routine.

High-dose eicosapentaenoic acid (EPA) improves attention and vigilance in children and adolescents with attention deficit hyperactivity disorder (ADHD) and low endogenous EPA levels

No studies have examined the relationship between endogenous polyunsaturated fatty acids (PUFAs) levels and treatment response to PUFAs. We conducted a 12-week, double-blind, placebo-controlled trial comparing the effects of high-dose eicosapentaenoic acid (EPA, 1.2 g) and placebo on cognitive function (continuous performance test) in n = 92 youth (age 6–18-years-old) with Attention Deficit Hyperactivity Disorder (ADHD). Blood erythrocytes PUFAs were measured before and after treatment, to examine the effects of baseline endogenous EPA levels on treatment response and the effects of EPA treatment on PUFAs levels. Secondary measures included other ADHD symptoms, emotional symptoms, and levels of plasma high-sensitivity c-reactive protein (hs-CRP) and brain-derived neurotrophic factor (BDNF). Overall, EPA group improved more than placebo group on focused attention (variability, Effect size (ES) = 0.38, p = 0.041); moreover, within youth with the lowest baseline endogenous EPA levels, EPA group improved more than placebo group in another measure of focused attention (hit reaction time, HRT, ES = 0.89, p = 0.015) and in vigilance (HRT interstimulus interval changes, HRTISIC, ES = 0.83, p = 0.036). Interestingly, EPA group improved less than placebo group in impulsivity (commission errors), both overall and in youth with the highest baseline EPA levels, who also showed less improvement in other ADHD and emotional symptoms. EPA increased blood erythrocytes EPA by 1.6-fold but not DHA levels, and did not affect hs-CRP and BDNF plasma levels. In conclusion, EPA treatment improves cognitive symptoms in ADHD youth, especially if they have a low baseline endogenous EPA level, while youth with high EPA levels may be negatively affected by this treatment.

Adverse Childhood Experiences and Family Resilience Among Children with Autism Spectrum Disorder and Attention-Deficit/Hyperactivity Disorder.

The purpose of the present study was to (1) examine the differences in adverse childhood experiences (ACEs) among children with autism spectrum disorder (ASD), attention-deficit/hyperactivity disorder (ADHD), and comorbid ASD/ADHD and healthy neurodevelopmental controls; (2) explore the levels of family resilience across diagnostic categories; (3) identify the differences in family resilience by the number of ACEs; and (4) explore the interaction between ACEs and the diagnostic category on family resilience. Participants were 2083 children between the ages of 6 and 17 years (M = 12.23, SD = 3.36) from the 2016 National Survey of Children's Health. The majority of the sample were male (68.7%) and white (78.6%). Overall, youth diagnosed with solely ADHD had the highest number of ACEs (Madj = 1.94). In addition, individuals who endorsed exposure to 1 ACE reported higher levels of family resilience in comparison to those who reported 0 ACEs or 2 or more ACEs. Family resilience did not differ between youth who experienced 2 or more ACEs and youth who experienced 0 ACEs. Youth diagnosed with comorbid ASD/ADHD had the lowest levels of family resilience. Interestingly, family resilience did not differ between ADHD and neurotypical youth. Youth diagnosed with ADHD seem to be at the highest risk for ACEs. Those with comorbid ASD/ADHD report the lowest levels of family resilience when controlling for exposure to ACEs. Families of youth with ASD had lower levels of family resilience than those of neurotypical youth when controlling for exposure to ACEs, whereas families of youth with solely ADHD displayed similar levels of family resilience in comparison to neurotypical youth and their families. Results have implications for prevention and intervention with ASD and/or ADHD youth and their families.

Predictive utility of autistic traits in youth with ADHD: a controlled 10-year longitudinal follow-up study

The objective of this study was to investigate the stability and predictive utility of autistic traits (ATs) in youth with attention-deficit/hyperactivity disorder (ADHD). Participants were referred youth with and without ADHD, without a diagnosis of autism spectrum disorder, and their siblings, derived from identically designed longitudinal case-control family studies of boys and girls with ADHD. Subjects were assessed with structured diagnostic interviews and measures of social, cognitive, and educational functioning. The presence of ATs at baseline was operationalized using a unique profile of the Child Behavior Checklist (CBCL) consisting of an aggregate T score of ≥ 195 on the Withdrawn, Social, and Thought Problems subscales (CBCL-AT profile). At the follow-up, 83% of the ADHD youth with a positive AT profile at baseline continued to have a positive CBCL-AT profile. The presence of a positive CBCL-AT profile at baseline in youth with ADHD heralded a more compromised course characterized by a greater burden of psychopathology that emerged at an earlier age, along with poorer interpersonal, educational, and neurocognitive outcomes. Findings indicate a high level of persisting ATs in ADHD youth over time, as indexed through the CBCL-AT profile, and the presence of this profile prognosticates a compromised course in adult life in multiple domains of functioning.

The Contribution of Sensory Sensitivity to Emotional Lability in Children with ADHD Symptoms

ABSTRACTEmotional lability and sensory sensitivity have been shown to contribute to the overall clinical picture in children with attention deficit hyperactivity disorder (ADHD). Further, both of these characteristics have been individually demonstrated to contribute to poorer quality of life, increased functional impairment, and poorer treatment response. However, to date, no study has evaluated the relationship among all three of these factors. The current study hypothesized that increased sensory sensitivity would moderate the relationship between hyperactive/impulsive symptoms of ADHD and emotional lability in youth. Results indicate that heightened sensory sensitivity strengthens the relationship between hyperactive/impulsive symptoms of ADHD and emotional lability in children with three or more clinically impairing ADHD symptoms. This dimensional approach was taken in accordance with growing evidence that even children with sub-threshold ADHD experience significant functional impairment and high rates of sensory sensitivity. These findings suggest that clinicians treating children with ADHD symptoms and emotional lability should consider assessing for sensory sensitivity as integration of multi-sensory techniques or referral to concurrent occupational therapy may significantly improve treatment outcomes and quality of life for these children and their families.
