Background: Children with ADHD have 2 to 3 times increased health care utilization and annual costs once diagnosed, but little is known about utilization patterns early in life, prior to diagnosis. Quantifying early health services use among children later diagnosed with ADHD could help us understand the early life impact of the disorder and uncover health care utilization patterns associated with

Background: Research on altered motivational processes in ADHD has focused on reward. The sensitivity of children with ADHD to punishment has received limited attention. We evaluated the effects of punishment on the behavioral allocation of children with and without ADHD from the United States, New Zealand, and Japan, applying the generalized matching law. Methods: Participants in two studies (Furukawa

Objective: This research involved the parents of ADHD students to explore how their children coped with online distance learning during COVID-19 pandemic and what implications this schooling method had on their emotional and behavioral well-being. Method: Data were collected during lockdown using an online questionnaire addressed to 100 mothers and were compared with 184 matched controls from a national

Objective: The trail making task is used to assess executive functioning in ADHD youth, yet has only been validated in adult populations. We compare the relative contributions of various cognitive measures to performance on a trail making task analog, the Switching of Attention (SoA) task, in typically-developing and ADHD adolescents. Method: Participants were 160 adolescents with ADHD from the International

Method A large sample of 3,688 post-secondary students

Objective Executive function deficits (EFD) are a central mechanism underlying negative outcomes in ADHD. This study examined awareness of EFD manifested in “real-time” task performance (Online Awareness) and in general self-knowledge of daily activities, outside the context of a specific task (Intellectual Awareness) among adolescents with and without ADHD. Methods 102 adolescents with (n = 52) and

Objective Children with attention-deficit/hyperactivity disorder (ADHD) show hypoactivity of the hypothalamic-pituitary-adrenal (HPA) axis. Whether the association between hyperactivity/inattention symptoms with HPA axis dysfunction holds in the general child population too is not clear. Method We assessed associations between longitudinal trajectories of hyperactivity/inattention symptoms during ages

Background: The objective of this study was to examine changes in the activation of the brain reward system following treatment with lisdexamfetamine (LDX) vs. placebo (PL) as a function of clinical improvement in attention deficit/hyperactivity disorder (ADHD) symptoms. Methods: Twenty adults with ADHD were included in a randomized cross-over study. Participants underwent two functional magnetic resonance

Background: Children with attention-deficit/hyperactivity disorder (ADHD) experience more sleep problems than their typically developing peers. In addition, their parents experience higher rates of mental health difficulties relative to parents of children without ADHD. Cross-sectional studies have reported associations; however, longitudinal studies have not yet been conducted. This study aimed to

Background: Individuals with an ADHD diagnosis have increased levels of interfering thoughts, especially in the form of mind wandering. This was mostly investigated in sustained attention tasks; hence it is unclear whether the findings are only due to their difficulties in those types of tasks. Moreover, it is unclear how the amount of control invested in the task will affect those differences between

Background Event perception provides a promising, novel approach for investigating underlying cognitive mechanisms of the social impairment associated with symptoms of ADHD. Aims The goal of this study was to establish the relationship among event perception, symptoms of ADHD, and social skills.

Method: The sample was composed of 30 children (9–14 years old) with an ADHD diagnosis and their parents. Participants were randomized into two groups, the MYmind group (n = 15) and a wait-list

Objectives: Emotional dysregulation (ED) in adult ADHD is frequent but definition and tools for its evaluation are not consensual. Our aim was to determine the core ADHD symptomatic domains via the Self-Reported Wender-Reimherr Adult Attention Deficit Disorder Scale (SR-WRAADDS) following its validation in a large clinical sample of adults with ADHD and controls. Method: Three hundred sixty-nine adult

In recent years, rates of prescription stimulant misuse have increased among young adults ages 18 to 25 along with increases in dispensing rates of these medications. Preliminary studies suggest that college students with Attention-Deficit Hyperactivity Disorder (ADHD) may be more likely to misuse their stimulant medication than their non-ADHD peers. Research is needed to further explore possible rates

Background Prior studies show that ADHD prevalence rates vary by race-ethnicity, but these studies do not include a full range of racial-ethnic minority groups. Objective This study aimed to understand differences in ADHD prevalence among children across a wider range of racial-ethnic groups, overall and stratified by biological sex. Method Data on children aged 5 to 17 from the 2004 to 2018 National

Objective: The COVID-19 outbreak created numerous multidimensional stressors, to which people show different levels of vulnerability. The current paper examines whether symptoms of ADHD are associated with poorer adaptation. Method: After the first quarantine in Israel, 2,055 adults participated in an online survey. Participants completed scales probing adaptation indicators: financial status, adherence

Objective: The adverse outcomes associated with ADHD are well known, but less is known about the minority of children with ADHD who may be flourishing despite this neurodevelopmental risk. The present multi-informant study is an initial step in this direction with the basic but unanswered question: Are there resilient children with ADHD? Method: Reliable change analysis of the BASC-3 Resiliency subscale

Objective ADHD symptoms typically decline with age, but less is known about whether the presentation of specific ADHD symptoms differs across development. This study aimed to examine the frequency and associated impairment of specific ADHD symptoms in childhood, adolescence, and young adulthood.

Methods: We conducted exploratory factor analysis (EFA) and exploratory structural equation modeling (ESEM) with

We investigated autonomic arousal, attention and response conflict, in ADHD and autism. Heart rate variability (HRV), and behavioral/electrophysiological indices of performance, were recorded during a task with low and high levels of response conflict in 78 children/adolescents (7–15 years old) with ADHD, autism, comorbid ADHD+autism, or neurotypical. ANOVA models were used to investigate effects of

Objective: There is an updated conceptualization of whole-lifespan attention-deficit hyperactivity disorder (ADHD), promoted by awareness of probable persistence of impairment into adulthood. We investigated cognition trajectories from adolescence to mid-adulthood in ADHD. Method: Data of 240 patients with ADHD and 244 healthy controls (HCs) were obtained; clinical symptoms and neuropsychological functions

Objective: The purpose of this study is to analyse DESR and its influence on sleep parameters in three different groups of children and adolescents: a group newly diagnosed with ADHD naïve, a group with ADHD under pharmacological treatment and a control group. Method: Subjects were a total of 327 children and adolescents. Two groups diagnosed with ADHD: 108 medication-naïve and 80 under pharmacological

Objective: Many children at risk for negative outcomes related to untreated attention deficit hyperactivity disorder (ADHD) do not receive necessary mental healthcare. Parents’ mental health-seeking behavior is important in the early identification of ADHD and preventing comorbidities with ADHD. Parents may experience some barriers that may delay or stop parents from seeking mental healthcare for their

Objective: Time-processing disorders in adults is a priority area for intervention. Time management program, which has been demonstrated to be effective in children with ADHD, has not been examined in adults. We anticipate the need for the development of specialized programs for adults. This is because it has been reported that time processing disorders have different patterns in childhood and adulthood

Objectives: To assess the association of HEDIS C&M phase follow-up measure with ADHD medication adherence. Methods: A retrospective study was conducted using Medicaid data (2014–2016) of children initiated with ADHD medication. Patients were categorized as meeting the C&M follow-up measure or not according to the HEDIS specifications. Medication adherence was measured using both Proportion of Days
