Defining the role of exposure to ACEs in ADHD: Examination in a national sample of US children

Examining the Association Between Adverse Childhood Experiences and ADHD in School-Aged Children Following the COVID-19 Pandemic

BACKGROUND

Adverse childhood experiences (ACEs) have long been associated with attention-deficit/hyperactive disorder (ADHD) diagnoses in children; but the data used is now over 6 years old (from 2017 to 2018). Understanding the current landscape of their prevalence and association is needed to capture evolving social, environmental, and economic conditions, and ensure interventions remain relevant to addressing current childhood trauma.

OBJECTIVE

This study provides an updated analysis of the association between ACEs and ADHD using post-acute-COVID-19 pandemic data.

PARTICIPANTS AND SETTING

This cross-sectional study of 10,518 children aged 5 to 17 years old derived data from the 2021 to 2022 National Health Interview Survey (NHIS).

METHODS

Differences in the prevalence of number (0, 1-3, or 4+) and type of ACEs by ADHD diagnosis were evaluated using Rao-Scott chi-square tests and multivariable logistic regression. All analyses incorporate complex survey weights.

RESULTS

In 2021 to 2022, 2,457 (23.3%) of children experienced ACEs and 1,115 (9.9%) had an ADHD diagnosis. Children with ADHD were more likely to experience every type of ACE and were more likely to have 1 to 3 or 4+ ACEs than children without ADHD. Children with 4+ ACEs had higher odds of having an ADHD diagnosis (aOR: 3.44, 95% CI [2.64, 4.49]) than children without ACEs. Male children, children with fair or poor health, and children living in rural counties were more likely to have an ADHD diagnosis, while children of color and uninsured children were less likely. We found the odds ratio of ADHD diagnosis for children with four or more ACEs, compared to those without ACEs, slightly lower than found in Brown et al., 2017's estimate of 3.97 (CI [3.29, 4.80]). These results suggest a consistent association between ACEs and ADHD when comparing pre-COVID data to our post-acute-COVID results.

CONCLUSIONS

These findings highlight the need for clinicians to consider traumatic stress in ADHD screening. Policymakers and early childhood organizations should encourage early screening and intervention for ACEs to reduce the impacts of ADHD diagnoses.

Trauma's distinctive and combined effects on subsequent substance use, mental health, and neurocognitive functioning with the NCANDA sample

PURPOSE

Traumatic brain injury (TBI) and potentially traumatic events (PTEs) contribute to increased substance use, mental health issues, and cognitive impairments. However, there's not enough research on how TBI and PTEs combined impact mental heath, substance use, and neurocognition.

METHODS

This study leverages a subset of The National Consortium on Alcohol and Neurodevelopment in Adolescence (NCANDA) multi-site dataset with 551 adolescents to assess the combined and distinctive impacts of TBI, PTEs, and TBI+PTEs (prior to age 18) on substance use, mental health, and neurocognitive outcomes at age 18.

RESULTS

TBI, PTEs, and TBI+PTEs predicted greater lifetime substance use and past-year alcohol and cannabis use. PTEs predicted greater internalizing symptoms, while TBI+PTEs predicted greater externalizing symptoms. Varying effects on neurocognitive outcomes included PTEs influencing attention accuracy and TBI+PTEs predicting faster speed in emotion tasks. PTEs predicted greater accuracy in abstraction-related tasks. Associations with working memory were not detected.

CONCLUSION

This exploratory study contributes to the growing literature on the complex interplay between TBI, PTEs, and adolescent mental health, substance use, and neurocognition. The developmental implications of trauma via TBIs and/or PTEs during adolescence are considerable and worthy of further investigation.

Attention-Deficit/Hyperactivity Disorder and Subsequent Trauma Exposure: The Mediating Role of Deviant Peer Affiliation

Individuals with ADHD symptoms are at an increased risk of lifetime trauma exposure. However, research has yet to fully examine whether symptoms of ADHD function as a temporal risk factor for experiencing trauma and specific mechanisms that may explain the association between symptoms of ADHD and trauma exposure. Two constructs that may account for the relation between ADHD symptoms and trauma are deviant peer association and neighborhood disadvantage. The present study sought to 1) elucidate the temporal nature of ADHD symptoms and exposure to trauma and 2) examine whether peer deviancy and/or neighborhood disadvantage mediate the relation between childhood ADHD symptoms and subsequent trauma exposure across a 20-year longitudinal cohort study. Participants (N = 616) were predominantly Black/African American (86%; Male n = 389) from an urban school district. Using structural equation modeling, total trauma exposures during young adulthood (Years 17-20) were regressed on parent- and teacher-rated ADHD symptoms in Grade 1 (Year 1). A significant indirect path from ADHD symptoms to trauma exposure through deviant peer affiliation (Year 16) indicated that having childhood ADHD symptoms predicted deviant peer affiliation 16 years later, which in turn predicted greater exposures to traumatic events during young adulthood, controlling for neighborhood disadvantage. Neighborhood disadvantage was not a significant mediator when accounting for peer deviancy. Taken together, findings contribute to a limited body of research that utilizes a prospective design to examine the association between childhood ADHD symptoms and trauma exposure in young adulthood among Black/African American youth. Potential targets for intervention are proposed.

Sleep insufficiency and bedtime irregularity in children with ADHD: A population-based analysis

BACKGROUND

Sleep is impaired in children with attention-deficit/hyperactivity disorder (ADHD). However, population-based examination of indicators of sleep insufficiency and bedtime irregularity is limited. This investigation examined associations between ADHD, weeknight sleep insufficiency, and bedtime irregularity in a nationally-representative child sample, and indicators of these sleep outcomes in ADHD.

METHODS

Parents of children aged 3-17 years with ADHD (n = 7671) were surveyed through the 2020-2021 National Survey of Children's Health. Inverse probability of treatment weighting generated a weighted matched control sample (n = 51,572). Weighted generalized linear models were performed without and with age-stratification to examine associations between ADHD and sleep, adjusting for sociodemographics in the full sample, and between nineteen sociodemographic and clinical variables and sleep in ADHD.

RESULTS

Having ADHD was associated with increased odds of sleep insufficiency and bedtime irregularity relative to controls, even after adjusting for sociodemographic variables. In ADHD, older age was associated with lower sleep insufficiency and greater bedtime irregularity. Black race, increased poverty, higher ADHD severity, depression, and increased screen time were associated with greater sleep insufficiency and bedtime irregularity. Adverse childhood experiences (ACEs) were associated with greater sleep insufficiency. Behavioral/conduct problems, female sex, and absence of both ADHD medication use and ASD diagnosis were associated with poorer bedtime irregularity. Age-stratified results are reported in text.

CONCLUSIONS

Children with ADHD face heightened risk for insufficient sleep and irregular bedtimes. Findings suggest intervention targets (e.g., Black race, poverty, depression, screen time) to improve both sleep insufficiency and bedtime irregularity. Results highlight ACEs and behavioral/conduct problems as targets to improve sleep insufficiency and bedtime regularity, respectively. Age-stratified findings are discussed.

Multidimensional ADHD Symptom Profiles: Associations with Adverse Childhood Experiences

OBJECTIVE

Adverse childhood experiences (ACEs) are associated with a range of negative health outcomes, including attention-deficit/hyperactivity disorder (ADHD) and neurocognitive deficits. This study identified symptom profiles in adult patients undergoing neuropsychological evaluations for ADHD and examined the association between these profiles and ACEs.

METHODS

Utilizing unsupervised machine learning models, the study analyzed data from 208 adult patients.

RESULTS

The Gaussian Mixture Model revealed two distinct symptom profiles: "Severely Impaired" and "Moderately Impaired". The "Severely Impaired" profile, 23.6% of the sample, was characterized by more severe ADHD symptomatology in childhood and worse neurocognitive performance. The "Moderately Impaired" profile, 76.4% of the sample, had scores in the average range for self-reported internalizing and externalizing psychopathology and better neurocognitive performance. There was a greater number of ACEs reported by patients in the Severely Impaired profile than the Moderately Impaired profile (p = .022). Specifically, using an ACEs cutoff of ≥4, 53.1% of patients in the Severely Impaired profile reported four or more ACEs, compared with 34.6% in the Moderately Impaired profile (p = .020). Profiles were not related to clinician-ascribed diagnosis.

CONCLUSIONS

Findings underscore the association between ACEs and worse symptom profiles marked by impaired neurocognitive function, increased internalizing and externalizing psychopathology, and heightened perceived stress in adults with ADHD. Future research may explore the effect of ACEs on symptom profiles in diverse populations and potential moderators or mediators of these associations. Findings offers valuable insights for clinicians in their assessment and treatment planning.

Abuse and Neglect of Children With Specific Learning Disorders in Türkiye: A Case-Control Study

BACKGROUND

Although it is often stated that children with special needs are at risk of being abused and neglected, research conducted on the abuse of children with specific learning disorders (SLDs) is limited.

METHODS

This case-control study aims to compare exposure to neglect and abuse among children diagnosed with SLDs (case group) and children with typical development (control group). The study included children aged 6 to 12 years who were referred to the Child and Adolescent Psychiatry Outpatient Clinic and Pediatric Clinic of a hospital in Türkiye. The data collection process included 196 participants and lasted for 7 months in 2020.

RESULTS

Based on the analysis of the data collected with the Schedule for Affective Disorders and Schizophrenia for School Age Children-Present and Lifetime Turkish Version (K-SADS-PL-T) and the Abuse Assessment Questionnaire, we determined that children with SLDs were physically and emotionally abused more than the children of the control group. In addition, they witnessed violence between their parents more than the control group. Physical abuse, emotional abuse and witnessing family violence were identified as significant predictors for SLD.

CONCLUSIONS

The presence of SLDs is a significant risk factor for children to be exposed to abuse even in the absence of ADHD as a comorbidity.

Developmental Neuroendocrinology of Early-Life Stress: Impact on Child Development and Behavior

Our internal balance, or homeostasis, is threatened or perceived as threatened by stressful stimuli, the stressors. The stress system is a highly conserved system that adjusts homeostasis to the resting state. Through the concurrent activation of the hypothalamic-pituitary-adrenal axis and the locus coeruleus/norepinephrine-autonomic nervous systems, the stress system provides the appropriate physical and behavioral responses, collectively termed as "stress response", to restore homeostasis. If the stress response is prolonged, excessive or even inadequate, several acute or chronic stress-related pathologic conditions may develop in childhood, adolescence and adult life. On the other hand, earlylife exposure to stressors has been recognized as a major contributing factor underlying the pathogenesis of non-communicable disorders, including neurodevelopmental disorders. Accumulating evidence suggests that early-life stress has been associated with an increased risk for attention deficit hyperactivity disorder and autism spectrum disorder in the offspring, although findings are still controversial. Nevertheless, at the molecular level, early-life stressors alter the chemical structure of cytosines located in the regulatory regions of genes, mostly through the addition of methyl groups. These epigenetic modifications result in the suppression of gene expression without changing the DNA sequence. In addition to DNA methylation, several lines of evidence support the role of non-coding RNAs in the evolving field of epigenetics. In this review article, we present the anatomical and functional components of the stress system, discuss the proper, in terms of quality and quantity, stress response, and provide an update on the impact of early-life stress on child development and behavior.

Hyperactivity and Impulsivity Symptoms Mediate the Association Between Adverse Childhood Experiences and Reading Achievement: A LONGSCAN Cohort Study

Adverse Childhood Experiences (ACEs) include various childhood stressors that can negatively impact the health and well-being of children. ACEs are associated with poor academic achievement. Attention is strongly associated with academic achievement, and there is a graded relationship between ACEs exposure and subsequent development of parent-reported ADHD; however, it is unclear whether ADHD symptoms mediate the relationship between ACEs and academic achievement. This study tested a model of mediation by ADHD symptoms between ACEs and academic achievement (measured by reading score). This retrospective cohort analysis utilized data from the Longitudinal Study on Child Abuse and Neglect (LONGSCAN), a data consortium exploring the impact of child maltreatment (n = 494). There were relatively even numbers of male and female child participants, and the majority of caregivers were either non-Hispanic White or Black. Path analyses were modeled for ACEs as a sum score and separately for individual ACE exposures, with number of symptoms of Inattention (IN) and Hyperactivity/Impulsivity (H/I) as mediators, and academic achievement as the outcome, adjusting for covariates. ACEs were highly prevalent in this sample (M = 5.10, SD = 1.90). After retaining significant covariates, significant direct associations (P < .05) were seen between ACE sum score and IN (β = .14) and H/I (β = .21), and between H/I and reading score (β=-.14). A higher ACE score was associated with lower reading scores through variation in H/I, but not IN. H/I mediated the relationship between ACEs and reading score in this high-risk population, providing new insight into relationships between ACEs and academic achievement, which can inform interventions.

Patterns of Adverse Childhood Experiences and Psychiatric Disorders Among Adolescents with ADHD: A Latent Class Analysis

There is limited existing research on whether specific combinations of Adverse Childhood Experiences (ACEs) are associated with different psychiatric disorders among adolescents with ADHD. This study aimed to address this gap by identifying classes of ACEs and examining their association with behavioral problems, anxiety, and depression in adolescents with ADHD aged 11-17 (n = 1,806), using data from the 2018 National Survey of Children's Health (NSCH). A latent class analysis revealed a four-class solution: (1) low-risk ACEs (61.6%), (2) moderate-risk ACEs (25.2%), (3) high discrimination and neighborhood violence exposure (7.6%), and (4) high-risk ACEs (5.6%). The "high-risk ACEs" and the "high discrimination and neighborhood violence exposure" class showed a higher likelihood of behavioral problems and depression, and anxiety and depression respectively. These findings provide some insight into the ACE patterns that are more likely to be associated with mental health problems among adolescents with ADHD.

Early Life Stress, Hormones, and Neurodevelopmental Disorders

BACKGROUND

Early life stress (ELS) describes a broad spectrum of adverse and stressful prenatal events, namely, prenatal maternal stress (PMS), or early postnatal events, which can have detrimental long-term influences on the physiology, cognition, and behavior of an individual. There is abundant evidence indicating that ELS exerts its lasting effects on the physical and mental health of the individual, likely acting through a number of mediating mechanisms, including the disruption of developmental programming of the fetus. Neurodevelopmental disorders (NDDs), for example, attention deficit hyperactivity disorder (ADHD) and autism spectrum disorder (ASD), are a group of conditions that typically manifest during infancy, childhood, or adolescence and are characterized by developmental deficits in various domains.

SUMMARY

The scope of the current mini-review is to provide an up-to-date summary of the findings regarding the association of ELS and NDDs and the possible hormonal mechanisms through which PMS exerts its impact on neurodevelopment. We focus on the available evidence regarding children and adolescents diagnosed with ADHD or ASD. ELS exposure during developmental vulnerability windows may increase the risk for either subclinical neuropsychological alterations or clinical conditions, such as NDDs. In fact, a large body of evidence underlies the association of ELS exposure and increased risk for NDDs in the offspring.

KEY MESSAGES

The majority of data suggest that ELS, including PMS, may be associated with ADHD and ASD in the offspring, although there is no consensus regarding the critical developmental periods. Carefully controlled prospective studies are needed to determine the possible causal processes and mechanisms underlying the association of ELS and NDDs.

Eye Movement Desensitization and Reprocessing (EMDR) as a Possible Evidence-Based Rehabilitation Treatment Option for a Patient with ADHD and History of Adverse Childhood Experiences: A Case Report Study

BACKGROUND

Children with Attention Deficit Hyperactivity Disorder (ADHD) having a history of adverse childhood experiences (ACEs) could be very difficult to treat with standard psychotherapeutic approaches. Some children diagnosed with ADHD may have Post-Traumatic Stress Disorder (PTSD) or have had experienced a significant traumatic event. Trauma and PTSD could exacerbate ADHD core symptoms and be a risk factor of poor outcome response.

OBJECTIVE

to report for the first time the history of a patient with ADHD and ACE successfully treated with an EMDR approach.

CONCLUSION

EMDR could be a promising treatment for ADHD children with a history of traumatic experiences in addition to pharmacological treatments.

Development of an electronic medical record provider evaluation template for children with attention deficit hyperactivity disorder

ABSTRACT

Attention deficit hyperactivity disorder (ADHD) is the most common neurobehavioral condition in children. Current guidelines recommend that Diagnostic and Statistical Manual of Mental Disorders Fifth Edition (DSM-V) criteria be met before diagnosing ADHD. However, 14-49% of providers are not documenting the use of DSM-V criteria in screening and diagnosis. The use of a standardized electronic health record (EHR) ADHD template is a potential option to assist providers with documenting the DSM-V criteria. The aim for this project was to provide a 1-hour educational in-service on the use of the DSM-V criteria, Vanderbilt rating scale, and a revised EHR ADHD template, and to assess provider use pre and post intervention. Results showed that few providers (n = 1; 2%) document using DSM-V criteria preintervention and post intervention with only a modest increase in template use (n = 3; 5%). However, there were statistical differences between provider type with advanced practice registered nurses and physician assistants screening more frequently using the EHR DSM-V ADHD template compared with physicians (p = .009). Future studies are needed to evaluate barriers to use, including practice preference, openness to change, and other factors that may affect provider workflow.

Childhood adversity associated with poorer health: Evidence from the U.S. National Survey of Children's Health

BACKGROUND

The association between adverse childhood experiences (ACEs) and increased risk of health problems is well established. However, many studies have relied on unrepresentative or high-risk samples and have focused on a narrow range of health problems. Prior research assessing potential age differences in the ACE-health connection is also sparse.

OBJECTIVE

To comprehensively examine the extent to which ACEs are associated with physical, mental, and neurodevelopmental health outcomes in childhood and assess whether these associations differ between age groups.

PARTICIPANTS & SETTING

Pooled cross-sectional data from the 2016-2019 National Survey of Children's Health (N = 98,732).

METHODS

We estimated age-stratified binary logistic regression models examining associations between the number of ACEs and physical, mental, and neurodevelopmental health problems net of sociodemographic and socioeconomic controls. Separate models were estimated for the total population (ages 3-17), early childhood (ages 3-5), middle childhood (ages 6-11), and adolescence (ages 12-17).

RESULTS

We observed a dose-response relationship between ACE exposure and childhood physical, mental, and neurodevelopmental health problems in all age groups. The largest disparities exist between children with no ACEs and three or more ACEs. Compared to children without ACEs, children with three or more ACEs had significantly higher adjusted odds of externalizing disorders (OR = 4.40), internalizing disorders (OR = 5.13), neurodevelopmental disorders (OR = 2.40), and physical health problems (OR = 2.08).

CONCLUSIONS

Our results add to evidence linking ACEs to childhood health disparities. Further, findings indicate that ACEs have persistent negative effects across age groups and that clinicians should monitor ACEs when assessing children's physical, mental, and neurodevelopmental health at any age.

Adverse childhood experiences predict neurite density differences in young children with and without attention deficit hyperactivity disorder

Adverse childhood experiences (ACEs) put millions of children at risk for later health problems. As childhood represents a critical developmental period, it is important to understand how ACEs impact brain development in young children. In addition, children with attention-deficit/hyperactivity disorder (ADHD) are more likely than typically developing (TD) peers to experience ACEs. Therefore, the current study examined the impact of ACEs on early brain development, using a cumulative risk approach, in a large sample of children with and without ADHD. We examined 198 young children (M_age  = 5.45, 82.3% Hispanic/Latino; 52.5% ADHD) across measures of brain volume, cortical thickness, neurite density index (NDI), and orientation dispersion index (ODI). For the NDI measure, there was a significant interaction between group and cumulative risk (ß = .18, p = .048), such that for children with ADHD, but not TD children, greater cumulate risk was associated with increased NDI in corpus callosum. No other interactions were detected. Additionally, when examining across groups, greater cumulative risk was associated with reduced ODI and volume in the cerebellum, although these findings did not survive a correction for multiple comparisons. Our results highlight the role early cumulative ACEs play in brain development across TD and children with ADHD.

[The mental burden of children, adolescents, and their families during the COVID-19 pandemic and associations with emotional and behavioral problems]

BACKGROUND AND OBJECTIVE

The infection protection measures adopted as part of the COVID-19 pandemic led to profound restrictions and changes in the social, (pre-) school, family, and leisure areas. The objective of the current study was to examine the mental burden of children and adolescents and their families during the COVID-19 pandemic. Furthermore, this study aimed to identify possible factors that influence the mental burden.

MATERIALS AND METHODS

The examinations were carried out between autumn 2020 and spring 2021 in a clinical sample (n = 280 patients aged 4-17 years) and a community sample (n = 1958 children and adolescents aged 4-19 years recruited via schools and preschools). Ratings of parents as well as children and adolescents via questionnaires were assessed.

RESULTS

Mental burden due to the corona pandemic was assessed as slightly to moderately increased across both rating perspectives and both samples. Overall, around 60 to 70% of the parents, children, and adolescents describe an increase in mental burden; in contrast, up to 12% of parents as well as children and adolescents describe relief. When comparing both samples, a slightly higher burden on children and adolescents can only be seen in the self-assessment of the clinical sample. None of the socio-demographic factors analyzed influences the mental burden statistically significant. However, low to moderate correlations between the subjectively experienced deterioration in the family and social situation and an increased level of stress is found.

DISCUSSION

Targeted interventions for exposed subgroups should be offered during a pandemic. Universal interventions are not indicated.

U.S. national, regional, and state-specific socioeconomic factors correlate with child and adolescent ADHD diagnoses pre-COVID-19 pandemic

Attention-deficit/hyperactivity disorder (ADHD), the most diagnosed emerging neurodevelopmental disorder in children, is a growing health crisis in the United States. Due to the potential increase in ADHD severity during and post the COVID-19 pandemic, we analyzed recent national and two state-specific ADHD data distribution among U.S. children and adolescents by investigating a broad range of socioeconomic status (SES) factors. Child and adolescent ADHD diagnosis and treatment data were parent-reported via National Survey of Children's Health (NSCH). The nationwide childhood prevalence of ADHD is 8.7%, and 62.1% of diagnosed children are taking medication. Louisiana (15.7%) has the highest percentage of children diagnosed with ADHD and California (5.6%) has the lowest, followed by Nevada (5.9%). Multiple correspondence analysis (MCA, n = 51,939) examining 30 factors highlights four areas of interest at the national and state level: race/ethnicity, financial status, family structure, and neighborhood characteristics. Positive correlations between ADHD diagnosis and unsafe school, unsafe neighborhood, and economic hardship are evident nationally and statewide, while the association between a lack of ADHD diagnosis and higher urban neighborhood amenities are evident nationally, but not in two opposing outlier states-Louisiana or Nevada. National and state-specific hierarchical analyses demonstrate significant correlations between the various SES factors and ADHD outcomes. Since the national analysis does not account for the demographic heterogeneity within regions or individual states, the U.S. should rely on comprehensive, county-specific, near real-time data reporting to effectively model and mitigate the ADHD epidemic and similar national health crises.

Longitudinal Relations Between Parental Strain, Parent-Child Relationship Quality, and Child Well-Being During the Unfolding COVID-19 Pandemic

As COVID-19 sweeps across the globe, scientists have identified children and families as possibly particularily vulnerable populations. The present study employed a developmental framework with two measurement points (the first at the peak of the lockdown restrictions (N = 2,921), the second after restrictions had been majorly loosened (N = 890)) to provide unique insights into the relations between parental strain, child well-being, and child problem behavior. Cross-lagged panel analyses revealed longitudinal effects of child well-being and problem behavior at T1 on parental strain at T2 with parent-child relationship quality as a moderator. True intraindividual change models showed that decreases in parental strain between measurement points predicted increases in child well-being and decreases in child problem behavior. Thus, the present research points to parental stress coping and child emotional adjustment as promising avenues for professionals and policy makers in their efforts to ensure child and family well-being throughout the pandemic.
