Active clinical trials for "Attention Deficit Disorder with Hyperactivity"

The purpose of this study is to see if a non-medication intervention can increase motivation in individuals with ADHD by observing brain activity using magnetic resonance imaging (MRI).

To assess the pharmacokinetics of a single dose of Aptensio XR® (methylphenidate hydrochloride extended-release) capsules under fed conditions in male or female children 4 to under 6 years of age with ADHD.

The purpose of this study is to develop a modified behavioral activation program in adolescents with ADHD to be implemented by school mental health providers in an urban, low-income school district. Subsequently we will examine its effectiveness in reducing depressive symptoms and improving emotion regulation and reward responsivity, compared to usual care.

The most common neuropsychiatric disorder in early childhood is attention deficit/hyperactivity disorder (ADHD) with evidence of abnormality in structure and function of brain. Epilepsy is one of the commonest comorbidity associated with ADHD with negative outcome on childrens' quality of life, and is considered to be a risk for academic underachievement. These two disorders are highly associated, with more possibility to be a bidirectional relationship. The mechanisms of this comorbidity are unknown. In this association, a difficult challenge is presented since antiepileptic therapy and drugs used to treat ADHD may aggravate the clinical picture of each other. The main objectives are to evaluate this overlap of those disorders, find their complications on child and his family, and to suggest possible solutions to improve the outcome of those children.

Parents of children with haemophilia will be invited to complete 3 questionnaires to look for traits present in ASD. With consent teacher will complete a further 2 questionnaires. If all 3 questionnaires are above threshold, then with consent of the family the child will be referred for further investigation. There are already pre-existing children with ASD who will be exempt from the study, but included in the data analysis of prevalence. The results of the 3 questionnaires will be used to identify a profile of social communication in children with haemophilia.

Forty children with and 40 children without Attention deficit Hyperactivity Disorder (ADHD) receive Docosahexaenoic Acid (DHA) and Eicosapentaenoic Acid (EPA) or placebo via a dietary intervention. Cognitive control functions are measured with functional Magnetic Resonance Imaging (MRI) before and after the intervention. Behavioural change is monitored with behavioural scales.

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 ultimate goal of this study is to find specific polymorphism of candidate genes (particularly of dopaminergic and noradrenergic systems) associated with intermediate phenotypes (e.g., executive functions, IQ, and other neuropsychological function) and/or phenomenological phenotypes (subtypes, comorbidity, dimensional approach) of ADHD. We propose to replicate the analysis of the candidate genes identified by previous genetic studies and recent findings from GWAS on ADHD using the candidate gene association study design (family-based case control study using parental controls and population-based case-control study). These results may lead our research team: (1) to resolve controversies over inconsistent findings in previous genetic studies and contribute to the literature on the validity of ADHD and its subtypes using clinical and genetic data; (2) to identify potential endophenotypes for ADHD genetic studies; and (3) to identify specific polymorphism of candidate genes and gene expressions of dopaminergic and noradrenergic systems associated with executive functions measured by the CANTAB.

These results will lead our team: (1) to resolve controversies over inconsistent findings in previous genetic studies and contribute to the literature on the validity of ASD using clinical and genetic data; (2) to study the pathogenetic process of abnormal genes in abnormal neuropsychological and neurobiological functions of ADHD; (3) to delineate the nature and the effect of gene-gene interaction in the etiology of ADHD.

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.
