Objective: Some studies show an association between ADHD and impaired balance/gait in children. However, it remains largely unexplored whether such an association exists in adults. We explore that association in this study. Method: This cross-sectional study included 45 adults aged 17 to 21 (25 with, and 20 without ADHD), most obtained from a…

Attention-deficit/hyperactivity disorder (ADHD) is one of the most common mental disorders of childhood. It is characterized by a pattern of inattention, impulsivity, or hyperactivity that leads to functional impairment experienced in multiple settings. Symptoms of ADHD occur during childhood, and many children continue to have symptoms and…

Objective: The current study aimed to elucidate characteristics of co-occurring ADHD and anxiety in a community-based sample of children. Previous work has highlighted the prevalence and associated impairment of each condition alone, but less research has focused on the co-occurrence of these disorders. Method: The present study first sought to…

Children with complex behavioral profiles (e.g., ASD + ADHD) may experience delays in obtaining a final diagnosis. Low-resource or underrepresented groups may be at even greater risk for delayed diagnosis. We assessed the effect of sociodemographic factors, symptom complexity and co-occurring conditions, and identifier of first symptoms on…

The present study deepens understanding of the relations between child, teacher, and classroom racial factors and teacher-reported externalizing behaviours by examining…

Introduction: This study examined whether adolescents with and without attention-deficit/hyperactivity disorder (ADHD) differed in affect variability and whether variability in positive and negative affect was associated with functional outcomes. Method: Participants were 302 adolescents (12-14 years, "M"age=13.17, 55% male; 54%…

According to the Multiple Deficit Model, comorbidity results when the genetic and environmental risk factors that increase the liability for a disorder are domain-general. In order to explore the role of domain-general etiological risk factors in the co-occurrence of learning-related difficulties, the current meta-analysis compiled 38 studies of…

Children with autism spectrum disorder have a high risk of vision problems yet little is known about their vision care. This cross-sectional survey study, therefore, examined vision care among 351 children with autism spectrum disorder ages 6-17 years in the United States or Canada who were enrolled in the Autism Treatment Network Registry. Vision…

Research on the effects of physical activity on children with attention deficit hyperactivity disorder is promising, yet no attempt has been made to integrate current findings using meta-analytic techniques. Using a meta-regression, the present study examined the effectives of physical activity for children with attention deficit hyperactivity…

Demographic and clinical factors may influence assessment of autism symptoms. This study evaluated these correlates and also examined whether social communication and interaction and restricted/repetitive behavior provided unique prediction of autism spectrum disorder diagnosis. We analyzed data from 7352 siblings included in the Interactive…
