Objective: We examined whether medical cannabis (MC) use was associated with change in ADHD symptoms across time in a sample of adults with chronic pain. Methods: We conducted a longitudinal cohort study (N = 223) across 12 months, assessing ADHD symptoms and MC use. We used mixed-effects linear regression to test whether MC use (vs. no use) and…

Purpose: Autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD) are conditions that similarly alter cognitive functioning ability and challenge the social interaction, attention, and communication skills of affected individuals. Yet these are distinct neurological conditions that can exhibit diverse characteristics…

College students with attention deficit hyperactivity disorder (ADHD) are a growing population, and they bring strengths and unique ways of processing information and solving problems. However, the academic success of students with ADHD has lagged behind that of their peers without ADHD, and higher education has not traditionally been designed to…

Children with autism or attention-deficit/hyperactivity disorder (ADHD) are more likely than neurotypical children to experience eating difficulties, such as picky/selective eating, slow eating, and over/under-eating. Recent studies show that eating difficulties can persist into adulthood for autistic individuals. Yet little is known about the…

Objective: This study aims to determine the prevalence of Attention Deficit Hyperactivity Disorder (ADHD), considering both parents' and teachers' reports and clinical diagnosis, and to examine the relationship between ADHD prevalence and measurement tools, sex, age, and clinical presentations. Method: This two-phase epidemiological study was…

Objective: Around 70% of adolescents with ADHD experience sleep and/or homework problems. Both impairments have been previously associated with neuropsychological deficits but have not been simultaneously examined in adolescents with ADHD and clinical sleep problems. Therefore, this study investigated how sleep problems are associated with…

The present study explores the relationships among executive functions (EFs) (working memory, inhibition, and cognitive flexibility), number of friends, friendship stability and friendship quality in neurotypical (NT) children and peers with attention deficit/hyperactivity disorder (ADHD) or dyslexia. The participants were 192 children…

Objectives: Work performance is a critical aspect of daily living, significantly impacted by the characteristics of ADHD. However, current research lacks sophisticated, theoretically, and empirically supported instruments for assessing work performance in this context. Therefore, this study aimed to develop a comprehensive and psychometrically…

Attention deficit hyperactivity disorder (ADHD) and dyslexia are among the most common neurodevelopmental disorders of childhood. The cognitive mechanisms underlying these disorders have not yet been fully clarified. Comprehensive assessment of cognitive and reading performance may provide valuable information to reveal the cognitive mechanisms…

Although sometimes perceived as a well-known condition, there are numerous aspects of Attention Deficit Hyperactivity Disorder (ADHD) which we do not fully understand. Given the preponderance of previous ADHD research with males, the need for understanding females' experiences of living with the condition is pressing. This article presents…

Background: Research has been inconclusive as to whether stimulant treatment causes or exacerbates sleep problems in adolescents with ADHD. This study examined sleep differences in adolescents with ADHD as a function of stimulant use. Methods: Participants were adolescents with ADHD (N=159, ages 12-14). Parents reported on receipt of stimulant…

Reading comprehension skills, which involve numerous executive functions (EFs), are crucial for the academic success of school-aged children. Because children with attention-deficit/hyperactivity disorder (ADHD) have difficulties with language comprehension and EFs, achieving reading comprehension may be challenging for them. This study evaluated…

Objective: A pilot study to preliminarily examine the effects of Prism EFP NeuroFeedback (NF) in adult ADHD. Method: Prism EFP NF is a form of NF specifically designed to target emotional dysregulation (ED) through down regulation of amygdala activity. Prism EFP NF has been shown to improve other disorders with significant ED. Nine participants…

Although neurobiologic and genetic factors figure prominently in the development of attention deficit/hyperactivity disorder (ADHD), adverse physical health experiences and conditions encountered during childhood may also play a role. Poor health is known to impact the developing brain with potential lifelong implications for behavioral issues. In…

This study aimed to explore the potential mediating role of sleep quality in the effect of physical activity (PA) intervention for improving executive functions (EFs) in children with attention-deficit hyperactivity disorder (ADHD). Participants aged 6 to 12 years old with a formal ADHD diagnosis were recruited from a local hospital. A total of 80…
