Active clinical trials for "Attention Deficit Disorder with Hyperactivity"

Attention Deficit Hyperactivity Disorder (ADHD) is the most common behavioral disorder in childhood, affecting 3-5% of children between the ages of 7 and 17. Family studies suggest that there is a genetic component to ADHD. Scientists believe that it is a complex disorder in which two or more genes may be involved. Potentially eligible families will be asked to give written consent to participate and will be asked to complete questionnaires for each member in the family. In addition, an interview will be administered to the parent of minors enrolled in the study to determine their eligibility for being in the study. This screening tool is computerized and will take approximately 45 minutes to administer per child. Once screenings are completed, a blood collection kit will be sent to the family to take to their local medical care provider, have blood samples drawn and sent to NIH. There is no cost to the family to participate. We would like to enroll entire families, with both parents and all children.

The objective of this research is to develop original virtual reality scenarios and/or new virtual reality equipments to evaluate or diagnose pathologies, such as attention deficit disorders or neuropsychiatric pathologies, addiction, anxiety or depression or pathologies interfering with sleep/wake disorders.

Non-interventional study to gain further information about the therapy progression in routine treatment of adults with attention-deficit/hyperactivity disorder (ADHD). Main focus will be on the improvement of the clinical global impression (CGI) in comparison to the outcome of randomized, controlled studies.

Specific Aims: To find the genetic variations associated with spatial working memory performance in patients with ADHD by using genome-wide association studies (GWAS); To find the genetic variations associated with spatial working memory performance in healthy subjects by using GWAS; To recruit a validation sample and to replicate the findings from the initial GWAS; To test whether genetic variations significantly associated with spatial working memory are also associated with ADHD.

The purpose of this study is to understand the pathophysiological mechanisms of ADHD, especially the metabolomic pathway related to the behavioral/neuropsychological deficits of ADHD. To identify specific metabolites that show significant differences between ADHD and control groups, both liquid chromatography-mass spectrometry and gas chromatography-mass spectrometry will be performed. In addition, the behavioral measures include ADHDRS-IV, SNAP-IV, CBCL, CGI-ADHD-S, SAICA, and Family APGAR-C. Neuropsychological testing, including CPT and CANTAB, will be performed. Conditional logistic regression and partial least squares discriminant analysis will be applied to identify significant metabolites for ADHD. Pathway enrichment and topology analyses will be conducted to evaluate the regulated pathways.

BACKGROUND: Attention-Deficit/Hyperactivity-Disorder (ADHD) is associated with language difficulties within expressive, receptive and pragmatic areas of language.Telling stories is a particularly interesting language task as is provides the possibility of investigating how children use their language in everyday interactions. Thus, investigating how children with ADHD tell stories provides a more naturalistic impression of their language abilities. However, the extent, causes, and clinical relevance of language and narrative difficulties in ADHD remain largely unknown. Language may be the key to understanding and improving the functional impairments associated with ADHD such as social and academic function. AIM: The overall aim of the current study was to investigate the association between language, narrative ability and ADHD, what contributes to this association, as well as the clinical relevance of language difficulties in ADHD in relation to academic and social function. METHOD: Children between 7-11 years old with ADHD will be recruited from Aarhus University Hospital in Skejby and compared to children without ADHD recruited from schools in the community. All children will be assessed at two separate meetings at the Department of Psychology, Aarhus University. The total number of participants in each group will depend on the intake of patients at Aarhus University Hospital, but a maximum of 100 children will be sampled in each group.

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

Attention Deficit Hyperactivity Disorder (ADHD) with a overall prevalence of 5.3% is one of the most common neurobehavioral disorders in children. In the foreign literature, many studies bring to light in children and adolescents the negative impact of ADHD on overall quality of life. Some of these studies were able to identify the fact that the higher the age of ADHD children or adolescents, the lower the quality of life. Currently, to our knowledge, only a few European studies have demonstrated the negative impact of ADHD on the quality of life of children and adolescents. In addition, these studies used only questionnaires intended for parents and not for children or adolescents. During a regular follow-up consultation with their referent child psychiatrist, adolescents accompanied by at least one of their parents will be informed of the modalities of our study. A newsletter will be delivered to parents and one to the adolescent. If neither the adolescent nor the parents is opposed to participate, the child psychiatrist will register the patient on the list of study participants. He will also fill out a medico-social information sheet about the adolescent as to summarize the data in the medical record. At the end of this consultation, in the waiting room, adolescents will answer questionnaires KIDSCREEN-27 and MSPSS; their parents will complete the CBCL questionnaire. These questionnaires will be handed to the secretary who will put them back in the patient's record. The KIDSCREEN-27, MSPSS and CBCL questionnaires as well as the medico-social information sheet will be source documents. The principal investigator or one of the associates investigators will complete the case report form from these source documents. For this purpose the data will be entered anonymously into a data entry software on a computer server secured by the Centre Psychothérapique de Nancy (CPN). Then, anonymous data from the software will be forwarded to Dr. Epstein of the Clinical Investigation Center for statistical analysis. The study will begin when the favourable opinion of the Ethical Research Comittees will be obtained and the study will last one year.

The aim of the study is to examine the prospective validity of neurocognitive functions and emotional factors in schoolchildren with ADHD and a control group of typically developing schoolchildren at baseline and after three years.

The purpose of this study is to document the extent of on-label and off-label use of Methylphenidate (MPH) (Concerta), MPH (Ritalin), Atomoxetine (ATO), and Guanfacine (GFC) in Japan.
