Neuropsychology, Neuroimage and Neurophysiology in Adults With ADHD

Attention Deficit Hyperactivity Disorder

We anticipate that drug-naïve ADHD probands, particularly those with DAT1 or SLC6A2 gene variants may have higher level of altered microstructural integrity of frontostriatal (FS), frontoparietal (FP), other hypothesized fiber tracts and decreased brain activity of FS, FP, and other circuits, deficits in ERP, and impaired EF, SA, IIA and VM than probands without DAT1 or SLC6A2 gene variants or adult neurotypical. The alterations in the structural and functional connectivity, neurophysiological and neuropsychological functioning would be observed in the unaffected siblings as compared to neurotypical. The unaffected siblings will be in the intermediate position between drug-naïve adult ADHD probands and neurotypical. The genetic dosage is anticipated to pose the strongest effects on the cortical thickness, brain volume, gyrification and microstructural property of white matter, followed by neurophysiology, functional connectivity, and neuropsychological function with the least effect. In terms of longitudinal follow-up part, we also anticipated despite increasing thinning of cortical thickness, microstructural integrity of several targets fiber tracts, and brain activity of target brain regions and improving performance in EF, SA, IIV, VM from childhood to late adolescence and young adulthood in the neurotypical group, the slopes of developmental trajectories of these neuroimaging and neuropsychological function are lower in the ADHD group.

The Effect of Methylphenidate Versus Placebo on State Anxiety in Children With Attention Deficit...

Attention Deficit Hyperactivity Disorder

The purpose of the study is to explore the effect of methylphenidate on state anxiety in children with attention deficit hyperactivity disorder. Patient population: 30 children diagnosed with attention deficit hyperactivity disorder. The subjects will be of all racial, ethnical and gender categories, ranging from 8 to 18 years of age. Structure: the study is a randomized double blind crossover study. The subjects will complete a continuous performance test, the cambridge neuropsychological test automated Battery, before and after given methylphenidate or placebo on the first day of the study. On the second day of the study, the subjects will receive either methylphenidate or placebo based on what was given on the first day of the study and they will complete the same task.

ADHD Medication and Predictors of Treatment Outcome

Attention Deficit Disorder With Hyperactivity (ADHD)

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.

System for Determining Ideal Drug Doses for ADHD - Stages 1 and 2

Attention Deficit Hyperactivity Disorder

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.

Near Infrared Spectroscopy in Children With Autism and ADHD

Attention Deficit Disorder With HyperactivityAttention Deficit Disorder3 more

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.

Efficacy of Combined Treatment With CoQ10 and Methylphenidate in Children With Attention Deficit...

Attention Deficit Hyperactivity Disorder

The aim of this study is to evaluate the effects of nutritional supplement co-enzyme Q10 (CoQ10) on methylphenidate-treated ADHD children in a randomized, double-blinded, placebo-controlled prospective study. All eligible patients will undergo randomization and divided into 2 groups: a CoQ10-enriched snack and a placebo snack group. According to power calculation, total of 60 subjects are expected to participate in the study. After the screening of eligibility (up to 14 days), the study is divided into three phases: pre-treatment (first assessment) phase (up to 14 days), treatment phase 8 weeks of treatment, and post-treatment phase. Screening: each participant will undergo screening for protocol eligibility within 14 days (two weeks) of recruitment. Subjects who meet all the inclusion criteria and signed an approved informed consent (both parents and the child) will be enrolled.

Associated Genes With Atomoxetine Response in Attention Deficit Hyperactivity Disorder (ADHD)

Attention Deficit Hyperactivity Disorder

Attention deficit hyperactivity disorder (ADHD) is the most common behavior disorder, with the prevalence of 3% to 6% in children and adolescents. The patients' academic achievements, professions and social livings are impaired. Comorbid antisocial behavior, substance abuse and delinquency burden family and society. Stimulants used to be the first line drug. But the medication compliance is poor because of strict drug administration. Atomoxetine is a new non-stimulant drug, which can effectively improve ADHD symptoms. But it achieves effect slowly, the drug responses differ significantly, and side effects interfere compliance. Since genetic factors is the most important cause for different drug responses, this project studies candidate genes potentially associated with atomoxetine medication, with the aim to find 2 to 3 gene polymorphisms influencing the drug response of ADHD. The study adopts cohort design. A sample of more than 100 ADHD cases with atomoxetine medication is to be collected. The rapid genotyping of large sample depends on high-through laboratory. New statistic method is to be used to improve the sensitivity of the target gene detection. There has been no such report in country and overseas. This project will provide basic information for forecasting drug response, improving clinical effects, tolerance and long-term compliance.
