Active clinical trials for "Attention Deficit Disorder with Hyperactivity"

Describe the prevalence of neurodevelopmental disorders among youth with criminal behaviors Explore the relationship between specific neurodevelopmental disorders and the rates and types of crime Examine the roles of psychiatric comorbidities and sociodemographic factors in juvenile criminality

The purpose of this study is develop a new assessment tool for Attention Deficit-Hyperactivity Disorder (ADHD) and to then test its validity (i.e. ability to discriminate between individuals with ADHD and healthy controls).

This study will compare two tests for attention deficit disorder (ADD) - the Test of Variables of Attention (TOVA) and the NIH Test of Attention - to see if they produce the same results. There are a number of problems with existing tests for ADD. For example, TOVA, the most commonly used test, operates only on older computers and has other problems as well. Because of these problems, NIDCD developed the new NIH Test of Attention. This study will determine if the new test is valid for ADD and how the performance on this test compares to the performance on the TOVA in the general population. Healthy volunteers between 6 and 60 years of age who have no problems with sight or hearing and are not taking medication for ADD may be eligible for this study. After a brief interview, participants take the first of the two study tests. On a second visit, they take the other of the two tests. Both tests ask the subject to respond to things they hear and see on a computer screen. Each test takes 30 to 45 minutes to complete. Some participants are asked to take the NIH Test of Attention a second time, on a third visit. Participants also take a 15- to 20-minute subtest of the Weschler Intelligence Test.

The purpose of this study is to understand the relationship between ADHD and the overall health of someone with ADHD. People who have ADHD have trouble paying attention, concentrating, organizing, and planning. They may have trouble in school, at work, and at home. The investigators are interested in finding out whether these difficulties have had any influence in the past, current, or future health problems of someone with ADHD. About 100 people with ADHD and 100 people without ADHD will take part in this research study, all through Massachusetts General Hospital (MGH).

The purpose of the study is to evaluate the psychometric validation of the Weiss Functional Impairment Rating Scale and the Weiss Symptom Record. It is hypothesized that the Weiss Functional Impairment Rating Scale has strong psychometric properties and good convergent validity with other measures of functioning and discriminant validity from symptoms and quality of life.

This proposal is to evaluate the reliability and validity of the Vanderbilt ADHD screening tool for use with adolescents and young adults aged 13-21 years. The Vanderbilt is a previously developed, freely available set of parent- and teacher-report questionnaires designed to identify ADHD and related disorders in children. The Vanderbilt measures have been chosen for inclusion in the new computerized Integrated Clinical Information Sharing System (ICISS) being rolled out in five Boston Children's Hospital (BCH) departments/divisions (Adolescent/Young Adult Practice, Children's Hospital Primary Care Center, Developmental Medicine Center, Department of Neurology, Department of Psychiatry). The Vanderbilt was developed and validated for use among children up to age 12 years (Wolraich et al., 2003; Wolraich et al., 2013; Bard et al., 2013), and little is known about its appropriateness for use among older youth. In addition, there is no self-report version of the Vanderbilt that can be administered directly to adolescents and young adults (ages 13-21 years), for whom parents and teachers are often less knowledgeable reporters. To address these shortcomings, a multidisciplinary team of BCH adolescent health clinicians and researchers modified the parent and teacher Vanderbilt questionnaires to make them age-appropriate for adolescents and young adults and created a complementary self-report version for adolescents and young adults. The goal of the current study is to 1) assess the feasibility and acceptability of online administration through the ICISS system of the new parent, teacher, and youth self-report Vanderbilt measures among adolescent and young adult BCH patients aged 13-21 years; 2) test their reliability in terms of internal consistency reliability, temporal stability of responses over a one-month test-retest, and inter-rater agreement across all informants (parents, teachers, and youths); and 3) test their validity by evaluating their convergence with a similar set of ADHD screening tools, the Conners scales, already validated for use with adolescents and young adults.

The main purpose of this study is to investigate how the brain responds to a procedure known as transcranial direct current stimulation (tDCS) and how tDCS affects performance on a behavioral task. Research suggest that this procedure leads to improvement in brain and behavioral measures of inhibitory control (controlling impulses) in healthy control participants. The investigators want to explore whether the same improvement will be seen in kids with ADHD.

Attention deficit/hyperactivity disorder (ADHD) is a common, impairing, childhood onset neuropsychiatric disorder with executive dysfunctions. The ADHD symptoms and executive deficits may last to adulthood. Our previous studies, like western results, have shown that children with ADHD have disrupted microstructural integrity of frontostriatal fiber pathways and impaired brain activity in frontoparietal network. However, there is lack of data with regards to whether adults with ADHD also demonstrate structural and functional disconnectivity of frontostriatal and frontoparietal networks as compared to healthy controls without ADHD in Asian population and no study has been done to correlate a wide range of executive functions with the connectivity of these two networks. Specific Aims: to compare the executive functions, and structural and functional connectivity in frontostriatal and frontoparietal circuitries between adults with ADHD and healthy controls without ADHD; to correlate the data from structural and functional connectivity, executive functions, and ADHD core symptoms stratifying by the ADHD and controls; and to explore other circuitries that may involve in ADHD by using whole brain tractography analyses.

We propose a population-based case-control study among 7000 elementary school children in semi-rural Johnston County, NC. Teachers will complete a screening form on each child. Controls will be randomly selected. Mothers of potential cases and controls will be interviewed by telephone about their child's symptoms of ADHD and exposure history, their family history of ADHD, and their reproductive and exposure history. Children's shed baby teeth will be analyzed for lead. Mothers will complete brief parenting scales and the Child Behavior Checklist. School records will be collected. The study goals are to identify risk factors for ADHD including preterm delivery and childhood lead exposure.

The objective of this study is to identification of neuropsychological, genetic and neuroimaging markers and treatment response predictors of attention-deficit/hyperactivity disorder (ADHD). Participants who take the standardized pharmacotherapy (methylphenidate or atomoxetine) for ADHD will be observed for 52 weeks. They will do several neuropsychological, neuroimaging and genetic tests at visit 1~6.
