Stimulants for ADHD
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial examines how stimulant medication affects behaviors in children and adolescents with ADHD who often exhibit disruptive behavior. Researchers will assess changes in preferences, reasons for disruptive actions, and impulse control. Participants will attend eight sessions, alternating between taking their medication and not taking it. Children or teens diagnosed with ADHD, who display disruptive behaviors such as aggression or tantrums, and are already on stimulant medication might be suitable for this study. As a Phase 4 trial, this study involves an FDA-approved treatment and aims to understand how it benefits more patients.
Do I have to stop taking my current medications for the trial?
For this trial, you will need to stop taking your stimulant medication on certain visits. Specifically, you will refrain from taking it on visits 2, 4, 6, and 8, but continue as usual on visits 1, 3, 5, and 7.
What is the safety track record for these stimulant treatments?
Research has shown that medications used to treat ADHD, known as stimulants, have been studied for safety. A thorough review found no increased risk of serious heart problems in children and young people taking these medications. However, common side effects occur more frequently compared to a placebo. These side effects can include trouble sleeping or loss of appetite.
Using certain stimulants, like methylphenidate, for a long time does not appear to increase the risk of serious mental health issues such as psychosis or tics. Evidence also indicates that ADHD medication can lead to fewer hospital visits for both mental and physical health issues and may lower the risk of suicidal behavior.
While stimulants are generally considered safe, awareness of possible side effects is important. Always discuss any concerns with a healthcare provider.12345Why are researchers excited about this trial?
Stimulants for ADHD are unique because they work by increasing the levels of certain neurotransmitters in the brain, specifically dopamine and norepinephrine, which help improve attention and focus. Unlike other treatments that might take longer to show effects, stimulants can often show improvements quickly, sometimes within just a few hours. Researchers are excited about these treatments because they have the potential to significantly improve the quality of life for children and adolescents with ADHD by reducing disruptive behaviors and enhancing their ability to concentrate and learn.
What is the effectiveness track record for stimulant medication in treating ADHD?
Studies have shown that stimulant medications like amphetamines and methylphenidate effectively reduce the main symptoms of ADHD. These medications improve quality of life more than a placebo, providing noticeable benefits. Research consistently shows that they help manage ADHD by enhancing attention and reducing impulsive behavior. In children and teenagers, these medications are well-known for aiding behavior and focus. Overall, stimulant medications offer a reliable option for managing ADHD symptoms.678910

What Are the Treatments Tested in This Trial?
Interventions
- Stimulant
Trial Overview
The trial tests how stimulant medication affects disruptive behaviors in kids with ADHD through preference assessments (choice of activities), functional analyses (behavior triggers), and choice assessments (impulse control). Participants alternate between medicated and non-medicated states across eight visits.
