Active clinical trials for "Attention Deficit Disorder with Hyperactivity"

Health literacy is an integral part of the pathway for the successful transfer of information between patients and providers. Parents of children with Attention Deficit/ Hyperactivity Disorder (ADHD) play an essential role in chronic care as they offer critical information to providers that drives appropriate education and disease management. We propose the development and evaluation of an electronic data entry tool that enables parents to communicate data essential to treatment of their children, regardless of their own literacy skills. The research plan addresses a question central to patient-centered information management: how does health literacy influence parents' report of data on ADHD and the process-level events that result from parent-provider communication? The following specific aims organize the clinical study: proposal: 1) To assess the effect of health literacy on successful completion of parent-reported ADHD health information in both paper-based and PCHR formats, and, 2): To determine the association between health literacy and process-level outcomes for ADHD that stem from parent-provider exchange of information. The formal evaluation will study a diverse cohort of parents in a randomized trial of data entry (paper versus PCHR) for ADHD-specific information. Primary care records for children of this cohort will be analyzed for the prior 12 month period. Both a retrospective examination of documented ADHD processes of care and a prospective evaluation of the utility of data from the PCHR will occur. Literacy level is a primary variable of interest throughout the evaluation.

Background: Literature has documented that children with attention-deficit/ hyperactivity disorder (ADHD) have difficulties in time management by manifesting with difficulties making plans, organizing tasks and activities, and awaiting their turns. However, the studies regarding time perception have been few as compared to those of neuropsychological measures and there is no information about this topic in Chinese population. In view of this, we will conduct a study to investigate the clinical and treatment aspects of time perception among children and adolescent with ADHD. Specific Aims: to examine the developmental and gender effect on the performance in time perception; to explore the deficit in time estimation, time discrimination, and time reproduction in children and adolescents with ADHD as compared to normal controls; to identify the association between ADHD symptoms and performance in time perception tasks; and to investigate the efficacy of MPH on the time perception measures among children and adolescents with ADHD; Subjects and Methods: This protocol consists of two studies. First, we will recruit 100 patients with DSM-IV ADHD, aged 9 to 16 years, and 100 school controls. They and their parents will receive K-SADS-E interviews. All of them will have complete assessments of time estimation, time discrimination, and time reproduction. Their parents also report on SNAP-IV and CPRS-R:S. The 2nd assessments will be performed 3 months later after the subjects received treatment at outpatients. Anticipated Results: We anticipated that the ADHD group will have poorer time perception, particularly in difficult tasks, and the impairment will be reduced after treatment with medication

The researchers plan to explore the validity of the category of ADHD NOS by identifying the risk for ADHD in the children of ADHD NOS adult probands and identifying common correlates of ADHD in these children. The researchers hypothesize that the rate of ADHD will be higher in the children of the ADHD NOS probands than the rate of ADHD previously published for siblings of proband children with ADHD; and ADHD children of ADHD NOS adults will have higher rates of school failure (as measured by their rate of repeated grades, need for tutoring, and placement in special classes) than their non-ADHD siblings.

Children with symptomatic HIV-1 (Human Immunodeficiency Virus) infection are at increased risk for developing severely disabling neurological and neuropsychological deficits. HIV-1 related CNS (Central Nervous System) disease is a clinical syndrome, manifested by varying and sometimes discordant degrees of cognitive, motor and behavioral impairment. A continuum of clinical presentations attributed to the effects of HIV-1 infection on the CNS, ranging from apparently normal development, decreases in the rate of new learning to the loss of acquired skills have been observed. Two domains of psychological functioning appear most susceptible to the effects of HIV infection on the central nervous system in children: expressive behavior and attentional processes (Brouwers, et al, 1994). Attention deficits have been documented as a relative weakness on the "freedom from distractibility" subclass of IQ tests (Brouwers et al, 1989) and on behavior assessment (Moss et al, 1994). Attention, however, has many subcomponents such as focused attention, divided attention, vigilance, etc. Direct assessment of attentional functioning using reaction time has not yet been conducted and questions whether attentional components are differentially affected by the virus have not been addressed. The proposed study would assess different components of attentional functioning in children with HIV-1 disease. A quantitative and systematic method is developed that could complement the existing standardized instruments used for measuring attention and neurocognitive function in this population. Simple alerted visual reaction time will be measured with varying preparatory intervals, a two-choice reaction time in a go/no-go paradigm will be administered, and a continuous performance, divided reaction time test and an object decision task will be given. Performance on these measures will also be related to measures of brain structure and stage of HIV-1 disease.

The purpose of this study is to improve the understanding of the genetic causes of specific neurologic and psychiatric disorders. The study will focus on conditions of mental retardation, childhood onset schizophrenia, attention deficit hyperactivity disorder (ADHD), atypical psychosis of childhood, and bipolar affective disorder. The study addresses the belief that there may be several genes contributing to the illness. Researchers intend to use several molecular genetic techniques in order to identify the areas of chromosomes containing genes responsible for the development of these disorders. Patients will be selected to participate in this study based on an early age of onset of their condition as well as the severity of the illness and the frequency of the illness among family members. Researchers will collect DNA samples from patients as well as affected and unaffected family members of each patient. The DNA samples collected will be analyzed for a variety of genetic abnormalities including; triplet repeat expansions, chromosome rearrangements, and polymorphisms.

This small pilot study will enroll children ages 5-12 years of age with disruptive behavior problems at school. These children and their families will be offered an enhanced model of primary care, which includes pre-visit record review, standardized content of primary care visits, post-visit care coordination by the primary care team, and coordination of services between the primary care team and the school. We hypothesize that children receiving this enhanced model of care will achieve better behavioral outcomes at both school and home.

Adolescents with attention-deficit/hyperactivity disorder (ADHD) obtain less sleep than their typically developing peers. Observational studies indicate that inadequate sleep is correlated with impairment in adolescents with ADHD, but it remains unknown if sleep is causally related to impairment. This study will use an experimental sleep restriction and extension protocol to evaluate sleep as a contributor to clinically significant impairment and possible target for intervention in adolescents with ADHD.

To explore the relationship between children's digital media usage and attention, activity, parenting pressure; to explore the relationship between family basic data factors and screen usage.

Impulsivity and/or hyperactivity in children has become one of the main clinical symptom for consultation, among the most frequent, in general or pediatric medicine. Among the different clinical forms of instability, ADHD appears to be an especially disabling condition for the development of the child, both in psychomotor, cognitive, emotional and relational aspects. Further, a significant link between ADHD children and some children with High Potential (HP) is observed. HP children show overall ahead cognitive developments compared to children with the same age. In these children, as well as in children with ADHD, an attention vulnerability, psychomotor deficits are noted, as well as emotional and relational deficits that significantly contrasted with some of their cognitive skills. Regarding the HP, the hypothesis is that children with significantly heterogeneous results (Complex) to the Wechsler IV scales are affected by this shift, and hence, by the difficulty of a differential diagnosis with ADHD, unlike those whose intelligence quotient (IQ) results that are more homogeneous (Laminar). The goal of this work was to study a population of 80 children aged from 8 to 12 years (20 subjects per group) to evaluate the functional and structural brain development by: Functional magnetic resonance imaging (fMRI) acquisitions with cognitive stimulations, involving attention, working memory and semantic processing, and emotional stimulations, fMRI acquisitions at rest (without activation), diffusion tensor magnetic resonance imaging (DTI) acquisitions, 3D anatomic acquisitions. Identification of developmental differences in certain cortical brain areas (eg, prefrontal vs parietal), white matter fiber bundles or functional networks preferentially used by one or other of these groups, will help to better understand this disease, and to improve the differential diagnosis in order to implement a more appropriate and personalized management of the patients via new therapeutic strategies.

People with ADHD often engage in risky behaviors, such as dangerous driving, substance abuse and gambling. Current behavioral economy theories differentiate between risk perception and risk attitude. This study aims to measure both risk taking and risk perception in adults with and without ADHD. It is hypothesized that people with ADHD show decreased risk perception, accounting for their risky behavior. In contrast, it is hypothesized that people with ADHD do not show increased risk attitude, namely, they are not risk seeking.
