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.

Structural and Functional Connectivity of Frontostriatal and Frontoparietal Networks as Endophenotypes...

Attention Deficit/Hyperactivity Disorder

Attention deficit/hyperactivity disorder (ADHD) is a common, impairing, clinically and genetically heterogeneous neuropsychiatric disorder with lifelong executive dysfunctions. The ultimate goal of this 3-year case-control imaging genomic study with unaffected siblings and typically developing (TD) children as controls is to identify useful imaging endophenotype for ADHD by investigating the structural connectivity, as assessed by diffusion spectrum imaging (DSI), and functional connectivity, as assessed by resting-state fMRI (rsfMRI) of brain regions related to cognitive/executive controls with regards to the ADHD status and the presence of dopamine transporter gene variants (DAT1). Specific Aims: to validate the executive functions, visuospatial memory, and structural and functional connectivity in frontostriatal, and frontoparietal circuitries as effective neurocognitive endophenotypes; to correlate the data from structural and functional connectivity, neuropsychology, and ADHD core symptoms stratifying by the presence of ADHD, proband-unaffected sibling dyads, and the presence of DAT1 variant; and To investigate reported candidate genes, in addition to DAT1 variant, related to dopamine and noradrenergic neurotransmitter systems in the association with neurocognitive endophenotypes such as DRD1, DRD2, DRD4, DRD5, DBH, MAO-A, ADRA2A, ADRA2C, NET, and COMT.

Pharmacokinetics of Understudied Drugs Administered to Children Per Standard of Care

AdenovirusAnesthesia57 more

Understudied drugs will be administered to children per standard of care as prescribed by their treating caregiver and only biological sample collection during the time of drug administration will be involved. A total of approximately 7000 children aged <21 years who are receiving these drugs for standard of care will be enrolled and will be followed for up a maximum of 90 days. The goal of this study is to characterize the pharmacokinetics of understudied drugs for which specific dosing recommendations and safety data are lacking. The prescribing of drugs to children will not be part of this protocol. Taking advantage of procedures done as part of routine medical care (i.e. blood draws) this study will serve as a tool to better understand drug exposure in children receiving these drugs per standard of care. The data collected through this initiative will also provide valuable pharmacokinetic and dosing information of drugs in different pediatric age groups as well as special pediatric populations (i.e. obese).

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.

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.
