The study compared the attention-deficit/hyperactivity disorder (ADHD) related clinical symptoms and a wide-ranging attention performance in 216 youths with autistic disorder (autism), 138 youths with Asperger’s disorder (AD) and 255 typically-developing youths. The diagnosis of autism and AD were made based on the clinical assessments according to the DSM-IV criteria and confirmed by the Autis...

BACKGROUND Attentional complaints are common in narcolepsy patients and can overlap with daytime sleepiness features. Few studies attempted to characterize attentional domains in narcolepsy leading to controversial results. We aimed to assess the impact of hypocretin deficiency on attentional functioning by comparing performances on the attention network test (ANT) of narcoleptic patients with ...

Objectives: This study performed a statistical analysis comparing adolescents with Attention Deficit Hyperactive Disorder (ADHD) and a control group in the Conners’ Continuous Performance Test (CCPT) 5 factor model, proposed by Egeland and Kovalick-Gran (2010a). Methods: The clinical group was composed by 28 participants with ADHD (17 male). The adolescents were divided in two groups regarding ...

Attention-deficit hyperactivity disorder (ADHD) affects approximately 3%-5% of children in the United States. In the current psychiatric nomenclature, ADHD comprises three subtypes: inattentive, hyperactive-impulsive, and combined. In this study, we used four analytic strategies to examine the association and linkage of the dopamine transporter gene (DAT1) and ADHD. Our sample included 122 chil...

BACKGROUND This study examines the diagnostic accuracy of the CBCL syndrome AS scales for predicting DSM-IV Attention Deficit-Hyperactivity Disorder (ADHD) and Oppositional Defiant Disorder with or without Conduct Disorder (ODD/CD). METHODS The sample included 370 children (187 probands and 183 siblings) participating in a family genetic study of attention and aggressive behavior problems. Un...

Attention deficit hyperactivity disorder (ADHD) is a childhood-onset psychiatric disorder whose cardinal symptoms are inattention, hyperactivity and impulsivity1. Diagnostic criteria for ADHD are based on extensive empirical research and appropriately lead to the diagnosis of a syndrome with higher interrater reliability, high predictability of course and medication responsiveness. The criteria...

This paper provides a brief overview of the nature of attention-deficit/hyperactivity disorder (ADHD) in children and the current criteria used in its clinical diagnosis. While the disorder continues to be viewed as one of inattention and/or hyperactive-impulsive behavior, theories of ADHD are beginning to focus more on poor inhibition and deficient executive functioning (self-regulation) as be...

EXTREME PREMATURITY AND ATTENTION IMPAIRMENT Preterm infants are at increased risk for a wide range of developmental disorders, including sensory, motor, cognitive, and other brain disorders (Lorenz et al., 1998; Bhutta et al., 2002; Aarnoudse-Moens et al., 2009), and the risk is highest for those infants born before 28 weeks gestation, i.e., extremely preterm or extremely low gestational age i...

Recent research on the DSM-IV subtypes of attention-deficit/hyperactivity disorder (ADHD) has demonstrated that the subtypes differ in demographic characteristics, types of functional impairment, and profiles of comorbidity with other childhood disorders. However, little research has tested whether the subtypes differ in underlying neuropsychological deficits. This study compared the neuropsych...

OBJECTIVE To compare the official arrest records for a large number of hyperactive boys (N = 179), most with conduct problems, and 75 control boys; to examine childhood IQ, socioeconomic status, and parent reports of childhood hyperactivity and conduct problems for their contribution to criminal behavior in adulthood; and to compare adult outcome for multimodality-treated (MMT) and drug-treated...
