Objective: ADHD is a prevalent neurodevelopmental disorder characterized by symptoms of inattention and hyperactivity-impulsivity. Impairments in executive functioning (EF) are central to models of ADHD, while alpha-band spectral power event-related decreases (ERD) have emerged as a putative electroencephalography (EEG) biomarker of EF in ADHD.…

It is well-known that children with attention-deficit/hyperactivity disorder (ADHD) and specific learning disorder (SLD) often exhibit behavioural and emotional problems. However, little is known about how these problems compare between the two groups of children. This study sought to fill this gap in knowledge by comparing the executive functions…

3q29 deletion syndrome (3q29del) is associated with neuropsychiatric and neurodevelopmental phenotypes. We previously reported that graphomotor weakness is present in up to 78% of individuals with 3q29del. We have now explored nuances of the graphomotor phenotype and its association with other comorbidities in this population. Participants were…

Since the beginning of the COVID-19 pandemic, students have endured drastic changes in educational routines. Such disruptions can be especially challenging for students who struggle with executive functioning, self-regulation and emotion regulation, such as students with autism spectrum disorder (ASD), attention deficit hyperactivity disorder…

This randomized, controlled study examined the initial efficacy of an executive function training program for children with autism spectrum disorder. Seventy 7- to 11 year-olds with autism spectrum disorder and intelligence quotients [greater than or equal to]80 were randomly assigned to receive a web-based set of executive function training games…

Objective: Children with ADHD often experience functional impairments across various aspects of daily life. This study addresses the dearth of longitudinal research on functional impairment trajectories from preschool to school age in children with symptoms of ADHD and comorbid disorders. Methods: We investigated the extent to which functional…

Attention-deficit/hyperactivity disorder is one of the most common comorbidities in individuals with autism spectrum disorder. However, the clinical implications of the co-occurrence of these two disorders are still poorly understood. Based on a preregistered protocol (PROSPERO CRD42020193880), this systematic review identified 34 articles,…

Executive Function (EF) and Effortful Control (EC) have traditionally been viewed as distinct constructs related to cognition and temperament during development. More recently, EF and EC have been implicated in top-down self-regulation - the goal-directed control of cognition, emotion, and behavior. We propose that executive attention, a…

Despite frequent reliance on teacher and parent ratings of children's behavior for multi-informant assessment, agreement between teachers' and parents' ratings is low. This study examined the predictive utility of teacher and parent ratings for children's self-regulatory outcomes (i.e., executive function, continuous performance task) in four…

The mediators of real-world executive functions in autism during the transition into adulthood are mainly unknown. This study aimed to identify the mediators for the behavioral and cognitive domains of real-world executive functions in late adolescent and young adult autistic populations. We followed up 289 autistic children (aged 11.6 ± 3.8, male…

Adolescents with autism spectrum disorder frequently experience social communication difficulties, executive functioning deficits, and anxiety and depressive symptoms, which are similar to the symptoms and correlates of sluggish cognitive tempo. Although sluggish cognitive tempo is related to, but distinct from, the inattentive and…

Approximately one in 10 children in the United States is diagnosed with attention-deficit/hyperactivity disorder (ADHD), a disability that can negatively affect academic achievement, yet relatively few children with ADHD are in special education. To better understand factors that determine which students with ADHD are in special education, we…

Adults with autism spectrum disorder often experience co-occurring mental health problems such as attention-deficit/hyperactivity-disorder, as well as impairments in executive function. Sluggish cognitive tempo, a cluster of behaviors including slow processing, daydreaming, and mental fogginess, has been shown to be associated with…

This study investigated the association of a performance-based measure of executive functioning (EF) with academic, social, and behavioral performance ratings in a convenience sample of 153 children aged 5 to 12 (78% male, 83% Caucasian) diagnosed with attention-deficit/hyperactivity disorder (ADHD). Multivariate regression showed that above and…

Due to an increasing number of students with ADHD in higher education and the difficult course of their academic career, a comprehensive overview of participation and functioning of this group is needed. A comprehensive search was performed in MEDLINE (PubMed), EMBASE, CINAHL and ERIC electronic databases in June 2014. This systematic literature…
