Active clinical trials for "Attention Deficit Disorder with Hyperactivity"

The purpose of this study is to find out whether prolonged treatment with methylphenidate has any adverse effect on cardiac functions and measurements.

The primary purpose of this study is to investigate brain whether ADHD represents a disruption or a delay of brain development. Children and adolescents both with and without ADHD are asked to participate in several MRI sessions, two years apart. This will allow us to chart brain development over time, both in typical development and ADHD, and therefore to address whether ADHD represents a disruption or a delay of typical brain development.

The purpose of this research is to assess and determine brain oscillations or "brain signatures" of adult participants with Attention Deficit Hyperactivity Disorder (ADHD) relative to adult participants without ADHD using the technique electroencephalogram (EEG). Electroencephalogram is entirely non-invasive way of tracking brain activity.The main goal of this study is to establish biological factors for determining the diagnosis of Attention Deficit Hyperactivity Disorder (ADHD).

To demonstrate concordance between the Quotient ADHD System Report and standard DSM-IV based parent and teacher reported rating/assessment scales, currently the accepted method of symptom measurement for subjects diagnosed with Attention-Deficit/Hyperactivity Disorder (ADHD).

Some recent studies have found that adult attention deficit - hyperactivity disorder (ADHD) was frequent among patients with alcohol-dependence. However, no investigation has ever addressed whether ADHD may impact the drinking outcome. Moreover, most of the different aforementioned studies assessed ADHD using the ADHD self-report scale (ASRS). The ASRS is a screening questionnaire that is of limited diagnostic value, and the overrepresentation of high-score ASRS among patients with alcohol-dependence could be in part due to differential diagnoses such as antisocial or borderline personality disorders, executive function impairments, or isolated impulsiveness. The study aims to evaluate "ADHD: Gaps between patients with Alcohol Dependence and Impact on early Relapse" (AGADIR). In AGADIR, subjects with alcohol-dependence are recruited at the end of a residential detoxification program. They are assessed for ADHD using the ASRS, but also with a standardized diagnostic tool, i.e., the Diagnostic Interview for ADHD in adults (DIVA 2.0). Potential differential diagnoses are screened during the baseline visit. The patients are followed-up during the 12 first post-detox weeks, through a standardized psychosocial treatment. ASRS is re-performed at the end of the follow-up.

The purpose of this study is to show that Prepulse inhibition test of acoustic startle response is an indicator of objective diagnostic characteristics of attention deficit disorder in children and adolescents. by demonstrating that Prepulse inhibition test of acoustic startle response is impaired in children and adolescents suffering from attention deficit disorder in the relation to the normal function described in the literature. The investigators will try to prove our hypothesis by an experiment that consists of two phases: Phase I (about 25 minutes): The patient will enter the room, will be asked to sit on a chair, and will be asked to look at a computer screen showing silent video of aquarium fish, then the patient will be connected to both the Prepulse inhibition test device and the Galvanic skin response device and pass the tests. Phase II (about 25 minutes): After completion of Phase I, each participant will receive his daily regular dose of methylphenidate and after an hour and a half from taking the drug, will repeat the tests, both the Prepulse inhibition test and the Galvanic skin response test. Duration of the entire experiment is 140 minutes (two hours and twenty minutes).

This study intends to establish a relationship between oculovestibular eye tracking measures, measures of ADHD, and medication prescribed for ADHD.

Heavy metal has been reported that it can cause attention deficit and behavioral disturbance. The investigators hypothesis is that heavy metal is associated with children with attention deficit/hyperactivity disorder(ADHD).

Studies have shown that children with Attention Deficit Hyperactivity Disorder (ADHD) and emotional dysregulation are characterized by high severity of ADHD, comorbid behavior disorders and increased risk of chronic difficulties. New studies have shown promising results by focusing on improving emotional regulation. We lack knowledge about differences in symptom patterns, stability of symptoms over time, comorbid disorders, neurocognitive functions, knowledge and regulation of emotions, psychosocial risk factors and reactions to stress. Children 6 to 12 years admitted to specialist and diagnosed with ADHD will be recruited. ADHD children with and without emotional dysregulation defined as fullfilling the criteria for the diagnosis Disruptive Mood Dysregulation Disorder (DMDD) with regard to differences in symptom patterns, stability of symptoms over time, comorbid disorders, neurocognitive functions, knowledge and regulation of emotions, psychosocial risk factors and reactions to stress..

To assess wether methylphenidate reduces the prevalence of primary nocturnal enuresis in children with attention deficit disorder
