Attention Deficit Hyperactivity Disorder Clinical Trials

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. Read Less

The purpose of this current study is to conduct a conceptual replication with an independent evaluation team of the randomized controlled trial conducted by Langberg and colleagues, which demonstrated the efficacy of the Homework, Organization, and Planning Skills (HOPS) intervention. The study will be conducted under routine practice conditions with school staff serving as interventionists; the study sample will include the broad range of students with organization, time management, and planning problems. The study will examine how implementation factors (fidelity, engagement, working alliance) are related to outcomes, and it will explore the potential moderating role of school organization factors on outcomes.

The goal of this pilot clinical effectiveness trial is to compare a brief parent behavioral intervention (PBI) to a modified sleep focused PBI (SF-PBI) delivered by therapists in pediatric primary care for families of children 3-5 years old with sleep problems and early ADHD symptoms. The main aims are to: Aim 1: Demonstrate the acceptability, feasibility, and appropriateness of the sleep focused PBI (SF-PBI) delivered in pediatric primary care for preschool-aged children (3-5 years old) at elevated risk for ADHD. Aim 2: Examine change in target engagement (sleep) and ADHD symptoms among preschool-aged children at elevated risk for ADHD receiving SF-PBI compared to standard PBI. Read Less

The purpose of this study is to determine whether the catechol-O-methyltransferase (COMT) inhibitor tolcapone, relative to placebo, affects response to alcohol, decision-making, brain activation associated with alcohol cue reactivity, response inhibition, and selective attention, or alcohol drinking.

The goal of this clinical trial is to study the impact of Dyanavel on co-occuring fatigue in adults with Attention Deficit/Hyperactivity Disorder. The main question it aims to answer is whether Dyanavel XR leads to a statistically significant reduction in fatigue compared to placebo, as measured by the Fatigue Symptom Inventory. Read Less

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder that commonly persists into adulthood and is associated with significant life impairments. The current study evaluates the feasibility, acceptability, and preliminary efficacy of a group-based mindfulness intervention for first-year college students with ADHD. If found to be feasible, acceptable, and efficacious, subsequent research will examine its impact on a larger scale to have a broader public health impact for college students with ADHD. Read Less

The study team will examine the effects of FDA approved stimulant and non-stimulant medications for ADHD, among youth with ADHD and with and without Oppositional Defiant Disorder (ODD) or Conduct Disorder (CD), on reward systems of the brain using fMRI. Read Less

The study team will determine the association between d,l-methylphenidate (MPH) therapeutic outcomes in ADHD patients and genetic variants of CES1 and reveal key associations between CES1 genotypes and the PK and PD of MPH. Read Less

The investigators will examine the acute effects of stimulant medication on executive functioning. The rationale for the proposed study is to examine the efficacy of stimulants for college students with ADHD and help prevent stimulant misuse among college students without ADHD. The working hypothesis is that stimulants, compared to baseline and placebo conditions, will improve executive functioning for college students with ADHD but not for college students without ADHD. Improvements on executive functioning measures (e.g., CPT-IP, Spatial Span) will be examined through 2 (ADHD vs. non-ADHD) x 3 (Baseline, Placebo, Stimulant) repeated measures ANOVAs. Follow-up analyses will include paired comparisons. Expected outcomes are to confirm these hypotheses and demonstrate the need for further study of stimulants. If confirmed, the results will provide pilot data for a larger NIH grant proposal aimed at further examining the acute effects of stimulants (i.e., improved cognitive functioning with stimulants) and comparing them to the acute effects of physical exercise (i.e., improved cognitive functioning immediately after exercise). The investigators expect this outcome to have an important positive impact because it can help support stimulant medication as an effective treatment for college students with ADHD (DuPaul et al., 2012). Additionally, demonstration that stimulants do not improve executive functioning for college students without ADHD can be used to help prevent and discourage stimulant misuse and diversion on college campuses (Hartung et al., 2013).

The overall objective of this study is to examine physical exercise as an intervention for ADHD. The rationale for the proposed study is that physical exercise could serve as an effective treatment for college students with ADHD that has low costs, low risks, and ancillary health benefits and may address the limitations of existing treatments. The central hypothesis is that college students with ADHD will exhibit greater degrees of improvement in executive functioning (i.e., sustained attention, working memory) immediately following sprint interval training (SIT), relative to non-ADHD peers. This hypothesis was formulated based on preliminary studies demonstrating reduced ADHD symptoms and improved executive functioning following physical exercise. Multiple 2 (ADHD vs. control) x 2 (male vs. female) x 2 (exercise vs. none) repeated measures ANOVAs will be conducted to compare students with ADHD (n = 24) to controls (n = 24). The expected outcomes are to confirm this hypothesis and demonstrate the need for further study of physical exercise. If confirmed, the results will provide pilot data for a larger NIH grant proposal aimed at further examining the acute effects of physical exercise (i.e., improved cognitive functioning immediately following exercise) and also the chronic effects of physical exercise (i.e., improved functioning after engaging in regular exercise for an extended period). This outcome is expected to have an important positive impact because physical exercise may serve as an effective treatment for college students with ADHD that is less risky than stimulants, less time-consuming than therapy, and provides ancillary health benefits (i.e., increasing physical fitness, decreasing obesity).

In the current study, the investigators aim to understand the role of transcranial direct current stimulation (tDCS) in improving executive function across neuropsychiatric populations known to have deficits in this cognitive domain. Read Less

This study aims to determine the transient, modulatory effects of transcranial direct current stimulation (tDCS) on executive function and inhibitory control in patients with ADHD compared to healthy controls. Read Less
