The development of a quantitative electroencephalographic (QEEG)-based procedure for use in the assessment of attention deficit-hyperactivity disorder (ADHD) was examined through a series of studies investigating test reliability and validation issues. This process, involving a spectral analysis of the electrophysiological power output from a single, midline, central location (the vertex), was ...

Abstract Introduction Patients with either Idiopathic Hypersomnia or Narcolepsy demonstrate excessive daytime somnolence (EDS) resultant inattention mimicking Attention Deficit Hyperactivity Disorder (ADHD). ADHD also often express sleep problems including EDS. Thus, patients and idiopathic hypersomnia narcolepsy may share drowsiness as common features. However, it is not known whether EDS have...

OBJECTIVE To examine the effects of stimulant medication on the sleep functioning of children with attention-deficit/hyperactivity disorder (ADHD) and identify predictors of sleep problems as a side effect of taking stimulant medication. METHOD One hundred sixty-three stimulant-naïve children (72% boys) aged 7 to 11 years diagnosed with ADHD (120 with ADHD predominantly inattentive type, 43 w...

CONTEXT The DSM-IV definition of attention-deficit/hyperactivity disorder (ADHD) distinguished 3 subtypes that had not been extensively studied. OBJECTIVE To determine whether the ADHD subtypes are stable enough over time to be valid. DESIGN Longitudinal study with a greater-than 89% retention rate in 7 assessments over 8 years. SETTING Outpatient clinics. PARTICIPANTS Volunteer sample ...

Inattentive behavior is considered a core and pervasive feature of ADHD; however, an alternative model challenges this premise and hypothesizes a functional relationship between working memory deficits and inattentive behavior. The current study investigated whether inattentive behavior in children with ADHD is functionally related to the domain-general central executive and/or subsidiary stora...

objectives: attention-deficit/hyperactivity disorder (adhd) is the most common neurobehavioral disorder of childhood. children with adhd may experience significant functional problems. our objective was to examine the prevalence of adhd and its subtypes in iran. methods: pubmed, isi web of science, psychinfo, iranpsych, iranmedex, irandoc were searched. irandoc, iranmedex and iranpsych are iran...

This dissertation was motivated by two questions: 1) Do children with developmental disorders have reliable cortical characteristics that distinguish them from control children or that are unique for different disorder-subtypes? 2) Do these cortical characteristics reflect behavioural changes effectuated by an intervention? Five studies that contribute to answering these questions will be prese...

We examined the effects of parent adherence on child outcomes in two treatment strategies for the Predominantly Inattentive Presentation of attention deficit/hyperactivity disorder (ADHD-I): behavioral parent training adapted for ADHD-I (Parent-Focused Therapy [PFT]) and a multicomponent intervention that combined PFT, a child life skills group, and a classroom intervention (Child Life and Atte...

The aim of the present study was to investigate the ability of children with attention deficit/hyperactivity disorder-combined subtype (ADHD-C) and predominantly inattentive subtype (ADHD-PI) to direct their attention and to exert cognitive control in a forced attention dichotic listening (DL) task. Twenty-nine, medication-naive participants with ADHD-C, 42 with ADHD-PI, and 40 matched healthy ...
