The present study examined mediators and moderators of the relation between parental ADHD symptomatology and the development of child attention-deficit/hyperactivity disorder (ADHD) and oppositional defiant disorder (ODD) symptoms across the preschool years. Participants included 258 (138 boys) 3-year-old children (M = 44.13 months, SD = 3.39) with and without behavior problems and their parent...

BACKGROUND Child and adolescent psychopathology has been linked to increased sleep problems, but there has been less investigation of this relationship in younger samples with early-onset psychopathology. This study examined three specific but commonly observed aspects of sleep behaviors in young children - (i) Sleep onset latency, (ii) Refusal to sleep alone, and (iii) Nighttime awakenings - m...

BACKGROUND Attention-deficit/hyperactivity disorder (ADHD) has a range of aetiological origins which are associated with a number of disruptions in neuropsychological functioning. This study aimed to examine how low birth weight, a proxy measure for a range of environmental complications during gestation, predicted ADHD symptom severity in preschool-aged children indirectly via neuropsychologic...

Objective Discriminative utility of performance measures of inhibitory control was examined in preschool children with and without ADHD to determine whether performance measures added to diagnostic prediction and to prediction of informant-rated day-to-day executive function. Method Children ages 4-5 years (N = 105, 61% boys; 54 ADHD, medication-naïve) were assessed using performance measures...

BACKGROUND Hexachlorobenzene (HCB) is an organochlorine chemical that has been used in agriculture and industrial processes. Behavioral impairment after HCB exposure has been described in animal models, but little information is available in humans. OBJECTIVES Our goal was to study the association of prenatal exposure to HCB with the social behavior of preschool children. METHODS Two birth ...

Cortese et al. [1] proposed a link between attention-deficit hyperactivity disorder (ADHD), obesity, and iron deficiency in Postgraduate Medicine. A later meta-analyses conducted by Cortese et al. [2] concluded a positive association between attention-deficit hyperactivity disorder (ADHD) and obesity and overweight in both children and adults. Importantly, when the authors stratified the analys...

Attention deficit hyperactivity disorder (ADHD) is common in children, adolescents, and adults, with extensive research establishing it as a valid neurobiological disorder. Without intervention, ADHD can result in significant impairment throughout the lifespan for the individuals it afflicts. Fortunately, multiple evidence-based options are available for the treatment of ADHD, including several...

The present study examined the power of measures of early preschool behavior to predict later diagnoses of attention-deficit/hyperactivity disorder (ADHD) and oppositional defiant disorder (ODD)/conduct disorder (CD). Participants were 168 children with behavior problems at age 3 who underwent a multimethod assessment of ADHD and ODD symptoms and were followed annually for 3 years. Fifty-eight ...

METHODS This is a selective review focusing primarily on prospective follow-up studies. Relevant publications were selected by searching the MEDLINE and PubMed databases using keywords: ADHD, development, preschool, adolescent, ...
