Active clinical trials for "Attention Deficit Disorder with Hyperactivity"

Coordinated project whose objectives are: a) to test the effectiveness of a promotion of physical activity intervention (MOVI-KIDS) on preventing obesity; and b) to improve the academic performance in both children with and without attention deficit hyperactivity disorder (ADHD)

The practicality of most ADHD medications is not or only moderately examined under long term routine conditions. Therefore, in this multi-centre, multi-national prospective non-interventional study, a recommended follow-up time of 12 months will investigate the course of the therapy in children and adolescents with ADHD with prior MPH treatment and their medication change to dexamfetamine in several European countries under daily routine. It consists of a baseline visit under MPH or another ADHD drug therapy, a change to dexamfetamine, the prospective description of the titration phase and a 12 month maintenance phase. Data on the use of dexamfetamine in routine clinical practice will be collected to describe how dexamfetamine is prescribed, titrated and used in the population of ADHD patients and how these factors influence the general intensity of ADHD and safety events. This study will collect real world data of dexamfetamine and compare descriptively the general intensity of ADHD according to ADHD classification and the impairment due to ADHD under therapy with dexamfetamine to the general intensity of ADHD according to ADHD classification and the impairment due to ADHD under the prior therapy with MPH. Furthermore the utilization of dexamfetamine will be assessed with regards to treatment persistence, compliance, proportion of patients discontinuing treatment and reason for discontinuation. Due to the fact that patients will be treated according to local medical practice it is possible that medication will be changed during the observation period.

ADHD medication of children and adolescents is becoming increasingly common. Clinical experience and scientific studies have proven that approximately 30% of children/adolescents with ADHD do not benefit from this treatment. However, there is insufficient knowledge about who these children are. All children and adolescents, who start treatment with ADHD medication at public Child and Adolescent Psychiatry units in Stockholm, on Gotland, an in Västerbotten, will be asked to participate in the study. The investigators intend to monitor the patients´clinical symptoms and possible side-effects after treatment start. The investigators will collect background information and saliva samples from the patient and his/her parents to be able to study if there are any genetic (hereditary) or other markers that can predict positive or negative outcomes of the ADHD medication. With this information, the investigators aim at, to a greater extent, be able to individualize treatment choices for children and adolescents with ADHD without unnecessary, costly and possibly unfavorable treatment attempts.

The goal of this study is to create a formal, quantitative methodology to determine what is the most beneficial dose of Central Nervous System (CNS) stimulant (Ritalin, methylphenidate) to improve cognitive and behavioral function of children diagnosed with Attention Deficit Hyperactivity Disorder (ADHD) individually. If successful, it will change the way in which the dose of CNS stimulant for treating ADHD is determined for children in need of therapeutic intervention. The project will be focused on developing the necessary methodology to analyze the children's data with the drift-decision model (DDM), and to develop the required technology, i.e., a computer game with which to measure cognitive/behavioral function and its validation with eye-tracking measurements.

The study aims to evaluate whether or not an EEG (a type of brain scan) is useful in diagnosing youth with either ADHD, BPD, ASD. Youth with ADHD, BPD, ASD, and healthy controls (without ADHD, BPD, and ASD) will undergo an EEG, and the results will be analyzed using brain activity flow pattern analysis (BAFPA). Twenty subjects with each disorder and twenty without any of the disorders under study (controls) will be evaluated. All subjects will be comprehensively assessed with structured diagnostic interviews and neuropsychological testing. All EEG analyses will be conducted under blind conditions. Conditional probability and receiver operating characteristic (ROC) analyses will examine the diagnostic utility of the EEG scan, using the clinical diagnosis of ASD as the gold standard.

The objective of this protocol is to establish a comprehensive screening process to evaluate the eligibility of potential pediatric subjects for appropriate ADHD clinical research studies.

To enhance our capacity to correctly choose the appropriate medication for ADHD patients on the first try based on the presence of a particular variant of a gene that could be identified on a laboratory test. It is hypothesized that patients with Attention Deficit Hyperactivity Disorder (ADHD) who have failed to respond to methylphenidate medication, but do respond to amphetamines, have a higher than expected incidence the allelic variants of the SNAP 25 gene associated with ADHD, and mutations of the dopamine system genes DRD1, 2, 4, 5 and dopamine transporter and COMTand MAOA.

Background: - Near-infrared spectroscopy (NIRS) is a functional imaging technique that can be uses light to study brain function while allowing for movement. To look at blood flow in the brain, NIRS uses a low-power light source with detectors that see how the light changes as it passes through brain tissue. Brain blood flow can indicate which parts of the brain are active during different tasks. Researchers want to study children with attention deficit hyperactivity disorder (ADHD) and autism spectrum disorders (ASD) and will use NIRS to compare the blood flow in the brain of children with ADHD and ASD with that of typically developing children. Objectives: To see how well NIRS can detect changes in brain blood flow during tests of thinking and memory in children. To compare blood flow in the brains of typically developing children and those with ADHD or ASD. Eligibility: - Children between 4 and 8 years of age with ASD, ADHD, or children with no psychiatric diagnoses. Design: Participants will be screened for eligibility. Those who are taking stimulant medication for ADHD or ASD will need to stop taking it for 3 days before the study visit. After participating in a screening assessment, all participants will have one study visit. At this visit, they will have be asked to complete two tasks during a NIRS scan. For both tasks, they will react to images on a computer screen. This visit will last about 2 hours. This is a testing study only. No blood or other samples will be needed for this study.

In this study the investigators aim to investigate the relationship between environmental factors, lifestyle and symptoms of Attention Deficit Hyperactivity Disorder (ADHD). Initially the investigators intend to measure the relationship between nutritional quality, exercise and sleep and ADHD symptoms. And then measure whether a change made in the diet can improve the symptoms of ADHD.

The aim is to conduct a feasibility pilot study of a dietary intervention designed to optimise gut bacteria in children diagnosed with ADHD.
