Active clinical trials for "Attention Deficit Disorder with Hyperactivity"

The primary aim of this study is to assess whether naltrexone as a monotherapy is effective in treating ADHD in adults. Medications that increase dopamine are often effective treatments for ADHD. Since naltrexone is a kappa opioid receptor antagonist, it increases dopamine in the brain. The investigators predict that naltrexone as a monotherapy will be effective for ADHD symptoms in adults with ADHD. The investigators also plan to assess the effects of naltrexone on dopamine as measured by changes in serum prolactin. The investigators predict that naltrexone will increase dopamine as indexed by decreases in serum prolactin. This study will be a six-week, double-blind, placebo-controlled pilot study with adults 18-55 years of age with ADHD.

The primary purpose of the study is to assess long-term safety and tolerability of Edivoxetine in pediatric participants with attention deficit hyperactive disorder (ADHD).

The main purpose of the study is to help to understand the effect on children and adolescents who are stable on treatment with atomoxetine or osmotic-release oral system (OROS) methylphenidate for attention-deficit/hyperactivity disorder (ADHD) of not taking the medication for a maximum of 6 days over a 28-day study treatment period.

This study seeks to determine, using special sleep tests (polysomnography and actigraphy) if guanfacine extended release is able to improve nighttime sleep in children with ADHD - associated insomnia while improving daytime ADHD symptoms. Male and female children with diagnosed or suspected ADHD with sleep problems (difficulty falling asleep, difficulty staying asleep, or less than expected hours of sleep) will be recruited. After obtaining informed consent and assent (when appropriate) and after discontinuation of excluded medications, children will have evaluations of his or her sleep and evaluations confirming the ADHD diagnosis. Children who successfully pass screening will be enrolled into the double-blind, placebo-controlled, randomized investigation with 50% of participants receiving guanfacine extended release and 50% of participants receiving matching placebo. Using a flexible-dose optimization design based on ADHD symptom improvement and medication tolerability, the dose will be adjusted between 1 to 4 mg over the course of four weeks. At the end of medication adjustment (week 4 or 5), ADHD questionnaires, sleep questionnaires, and sleep tests will be repeated and analyzed. The medication will be weaned over the course of the following 3-10 days.

Individuals with ADHD are at markedly high risk for increased substance use and Substance Use Disorder (SUD). Given the strong evidence for the negative trajectory of individuals with co-occurring ADHD and substance use initiation, the goal of this study is to conduct a controlled examination of a brief, early intervention (BEI) for substance modified for adolescents with ADHD. Importantly, this intervention will address individuals who are at risk for problems with substance use, but do not yet meet criteria for severe SUD. Although brief interventions have been found to be effective in other populations, their efficacy in an ADHD population with emerging risk for substance use problems remains uninvestigated. This study aims to understand why some adolescents with ADHD and elevated risk for SUD respond to (BEI) and others do not. The investigators will test whether situational and individual characteristics predict substance use development and response to treatment. Further, this study will assess which types of additional treatment are most effective for youth who do not respond to the initial BEI. It is hypothesized that rates of adolescent substance use will be lower among adolescents who participate in study treatments.

The investigators are proposing to test a medication derived from our prior studies of the gene SLC9A9. This one gene makes NHE proteins that control how we learn and remember items, which is impaired in ADHD and may cause an inability to plan, prioritize, self-monitor,inhibit, initiate, self-correct, or control one's behavior. The investigators now propose to investigate the therapeutic utility of an NHE inhibitor, amiloride hydrochloride, for the treatment of attention deficit hyperactivity disorder (ADHD) in medication-naïve adults with ADHD.

The purpose of this study is to determine whether atomoxetine is effective in reducing ADHD (Attention Deficit/Hyperactivity Disorder) symptoms in adolescents with ADHD and comorbid cannabis abuse.

Research Question: Will daily engagement in activities tailored to the evidence-based vestibular research result in improved attention and learning outcomes for children ages 6-9 years of age after an 8-week classroom-based intervention?

The purpose of this study is to investigate the treatment effectiveness of Adhansia XR at month-2 after initiation, and the effectiveness of Adhansia XR overall and when compared with the active comparator group (Concerta) over time.

In this study the investigators will examine psychiatric symptoms, central neurocognitive functions, parental stress and attachment styles, and biological factors that can give new knowledge about some of the mechanisms present in children referred to outpatient psychiatric clinics. A specific focus will be given to children suffering from severe irritability.
