Active clinical trials for "Attention Deficit Disorder with Hyperactivity"

Inhibitory control allows individuals to suppress unwanted actions and to resist irrelevant stimuli. It is thought to be a core deficit in Attention-deficit/hyperactivity disorder (ADHD). The present study aims at evaluating this deficit in adults with ADHD. Executive and inhibitory capacities, as well as the neural mechanisms underlying inhibitory control, will be assessed in adults with ADHD and two control groups of participants.

Attention-Deficit/Hyperactivity Disorder (ADHD) is characterized by poor attention, impulsivity, hyperactivity and emotional-motivational dysregulation. Here, we will test if repetitive transcranial magnetic stimulation (rTMS) can reduce the symptoms of ADHD.

Background: Impulsivity is acting 'without thinking.' Compulsivity is being overly inflexible. People vary in how impulsive or compulsive they are. Extreme versions of these behaviors play a role in mental disorders. Researchers want to study changes in the brain to learn more about these behaviors. Differences in genes may also play a role. Objective: To learn about genetic and brain features that explain why levels of impulsivity and compulsivity vary across people. Eligibility: People ages 6-80 Design: Participants will be screened with a medical history and medical record review. Participants will talk about their mental and behavioral development. They may discuss topics like drug use and sexual activity. They will complete surveys about their compulsivity and impulsivity. Parents of child participants may also complete these surveys. Participants may take memory, attention, and thinking tests. They may give blood or saliva samples for gene studies. Participants may have a magnetic resonance imaging scan. It will take pictures of their brain. The scanner is shaped like a cylinder. Participants will lie on a table that slides in and out of the scanner. A coil will be placed over their head. They will lie still, watch a movie, and play a game. Participants may have a magnetoencephalography scan. It records brain activity. Participants will sit in a room. A 'cone' of magnetic field detectors will be lowered around their head. They will rest and play a game. Participants may ask family members to join the study. Participants under age 25 may repeat these tests every 1-2 years until they turn 25 or until the study ends. For those over age 25, participation will last less than 1 month.

The purpose of this study is to compare the recommendations made by TDApp2 with those by relevant clinical practice guidelines in children/adolescents with ADHD.

The aim of this study is to evaluate a novel tablet game-based neurodevelopmental assessment tool for young children aged 3 to 8 years old. The study's main aims are: (1) to determine whether the novel tablet-game based assessment tool can accurately differentiate children's neurodevelopmental status based on their performance on the game and (2) assess the validity of the game-based neurodevelopment assessment tool. The study aims to recruit 590 children who are 'typically' developing and/or have a diagnosed neurodevelopmental disorder including Attention Deficit Hyperactivity Disorder (ADHD), Autism Spectrum Disorder (ASD), Specific Learning Disorder, or a Communication Disorder. All participants will complete the tablet game-based assessment which aims to assess a range of neuropsychological functions including attention, memory, language, motor, executive functions and social-emotional skills. Parents/carers of participants will also complete a demographic questionnaire and the Adaptive Behaviour System - Third Edition (ABAS-3), which is a questionnaire that assesses a child's development. Some participants will be re-tested on the tablet game-based assessment approximately 2 weeks after the first tablet game-based assessment to ensure the game's validity.

This study aims to assess the behavioral as well cognitive changes in ADHD symptoms in terms of improvement of inhibitory control and attention in adults with ADHD

The goal of this study is to compare the influence of visual and auditory white noise on performance in children with attention deficit hyperactivity disorder (ADHD). The main questions it aims to answer are: Can auditory white noise stimulation affect cognitive performance? Can visual white pixel noise affect cognitive performance? Participants will complete two eye tracking tasks under different sensory noise stimulation. Researchers will compare the ADHD group with a group of typically developing children to see if the noise influences the groups differently and if it has the potential to affect the performance of the ADHD group, to reach the level of the control group.

This study examines the impact of cognitive training among participants with ADHD in Switzerland

The study investigators are interested in learning more about how drugs, that are given to children by their health care provider, act in the bodies of children and young adults in hopes to find the most safe and effective dose for children. The primary objective of this study is to evaluate the PK of understudied drugs currently being administered to children per SOC as prescribed by their treating provider.

This project is the first involving the two most common neurodevelopmental disorders, ASD and ADHD, as well as TDC to establish a multi-dimensional database (clinic, behavior, neurocognitive function, brain imaging, metabolomics, and microbiome) using the same methodology. Based on this integrated multi-dimensional databank, we anticipate exploring metabolic flows of the gut-brain axis during brain development and identifying the common and unique biomarkers of ASD and ADHD and high-risk materials related to their functions and the underlying mechanism. Moreover, distinguishing the characteristics of the gut microbiota, gastrointestinal disorders, and microbial flora dysbiosis also helps us, in turn, to accelerate the process of identifying biological treatments that can interfere or slow down the severity of cognitive impairments in neurodevelopmental disorders. Eventually, we anticipate finding the clinical and neurocognitive measures related to the direct or indirect influence of gut-brain signaling. Our findings are anticipated to improve the knowledge about neurodevelopmental disorders, enhance developing early detection, diagnosis, and treatment for ASD and ADHD, and contribute to precision medicine.
