Objective: Time reproduction is deficient in children with attention-deficit/hyperactivity disorder (ADHD). Whether this deficit is familial and could therefore serve as a candidate endophenotype has not been previously investigated. It is unknown whether timing deficits are also measurable in adolescent children with ADHD and nonaffected…

This paper aims to illustrate how combining multiple approaches can inform us about the neurobiology of ADHD. Converging evidence from genetic, psychopharmacological and functional neuroimaging studies has implicated dopaminergic fronto-striatal circuitry in ADHD. However, while the observation of converging evidence from multiple vantage points…

Background: Most diagnostic nomenclatures do not allow for the concurrent diagnosis of autism and attention-deficit/hyperactivity disorder (ADHD). Clinic-based studies suggest autistic symptoms are common in children with ADHD, but such studies are prone to referral bias. This study assesses whether children with ADHD selected from the general…

Attention-deficit/hyperactivity disorder (ADHD) among adults is characterized by inattentiveness and impulsivity. This article provides counselors with information about the etiology, assessment, and treatment of adult ADHD. The identification of the genetic and neurological features of ADHD has led to improvements in evaluation and treatment.…

Objective: To investigate the effect of melatonin treatment on sleep, behavior, cognition, and quality of life in children with attention-deficit/hyperactivity disorder (ADHD) and chronic sleep onset insomnia. Method: A total of 105 medication-free children, ages 6 to 12 years, with rigorously diagnosed ADHD and chronic sleep onset insomnia…

Neurofibromatosis, type 1 (NF-1) is a common genetic disorder affecting 1 in 3,500-4,000 individuals in the world. Mutations of the NF-1 gene produce a myriad of physical, medical, and psychological manifestations. Although there is a very high degree of variability in the manifestations between individuals with NF-1, the majority of children and…

The life-long neurological impairments found in people with fetal alcohol spectrum disorders (FASDs), including learning disabilities, impulsivity, hyperactivity, social ineptness, and poor judgment, can increase susceptibility to victimization and involvement in the criminal justice system (CJS). Individuals with FASDs become involved in the CJS…

This article reviews the research literature on psychosocial treatments for preschool-aged children with Attention-Deficit Hyperactivity Disorder (ADHD) in the context of the developmental and contextual needs of this population (e.g., increased parenting demands, differences in classroom structure, and the child's emerging developmental…

This report is primarily concerned with reporting on the normative results obtained on a large sample of serious adult offenders. An expanded Halstead-Reitan Neuropsychological Test Battery was administered to 584 adult offenders (OF), 132 normal controls (NC), and 494 acute psychiatric patients (PP). Subjects were between 18 and 44 years of age.…

Pelham, Wheeler, and Chronis (1998) reviewed the treatment literature on attention-deficit/hyperactivity disorder (ADHD) and concluded behavioral parent training (BPT) and behavioral classroom management (BCM) were well-established treatments for children with ADHD. This review updates and extends the finding of the prior review. Studies conducted…

This study assessed rates of learning disabilities (LD) by several psychometric definitions in children with epilepsy and identified risk factors. Participants (N = 173, ages 8-15 years) completed IQ screening, academic achievement testing, and structured interviews. Children with significant head injury, chronic physical conditions, or mental…

Like other developmental disorders such as Attention Deficit Hyperactivity Disorder, specific language impairment and dyslexia, there is no shortage of debate surrounding the condition of Developmental Coordination Disorder. The present article takes a global view of many of these debatable issues, starting with definition and terminology, moving…

We tested a conceptual model involving the inter-relations among affective decision-making (indexed by a gambling task), autonomic nervous system (ANS) activity, and attention-deficit/hyperactivity disorder (ADHD) and oppositional defiant disorder (ODD) symptoms in a largely impoverished, inner city sample of first through third grade children (N…

We examined parents' knowledge, attitudes, and information sources regarding Attention-Deficit/Hyperactivity Disorder (ADHD), including treatment with stimulant medication and behavioral interventions. Responses from parents with a child diagnosed with ADHD and parents without a child diagnosed with ADHD were also compared. Participants consisted…

Information on the development and functions of rostral prefrontal cortex (PFC), or Brodmann area 10, has been gathered from different fields, from anatomical development to functional neuroimaging in adults, and put forward in relation to three particular cognitive and behavioural disorders. Rostral PFC is larger and has a lower cell density in…
