What is the purpose of this trial?

This trial explores how mindfulness-based neurofeedback, which provides real-time feedback on brain activity, can reduce repetitive negative thinking in teens at risk of serious mental illness. Researchers aim to determine whether this approach can alter brain activity patterns, particularly in the default mode network, the part of the brain active during rest and self-referential thoughts. Participants will receive either active or sham neurofeedback sessions following mindfulness training. Teens who frequently experience negative thought loops and have an interest in mindfulness may be well-suited for this study. As an unphased trial, it offers a unique opportunity for teens to explore innovative mindfulness techniques that could enhance mental well-being.

Do I have to stop taking my current medications for the trial?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the study team or your doctor.

What prior data suggests that mindfulness-based neurofeedback is safe for adolescents?

Research has shown that mindfulness-based neurofeedback is generally safe and well-tolerated. This treatment uses brain feedback during meditation to improve mental health. Participants report few side effects, and it is considered non-invasive, as it doesn't involve entering the body.

In reviews, participants experienced minimal negative reactions, with most finding the experience comfortable and manageable. Although more studies are needed to confirm these findings, current evidence suggests mindfulness-based neurofeedback is a safe option for enhancing mental health. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about mindfulness-based neurofeedback for rumination because it offers a novel approach to managing persistent, repetitive thoughts that can be difficult to control. Unlike traditional treatments, such as cognitive-behavioral therapy or medication, which often focus on changing thought patterns or altering brain chemistry, this method uses real-time brain activity feedback to help individuals learn to regulate their mental processes. This neurofeedback technique can potentially provide users with a more direct and empowering way to modify their brain function, potentially leading to more effective and lasting relief from rumination.

What evidence suggests that this trial's treatments could be effective for reducing repetitive negative thinking?

Research shows that mindfulness-based neurofeedback (mbNF), which participants in this trial may receive, can help reduce overactivity in the default mode network (DMN) of the brain. Previous studies have found that mbNF lessens repetitive negative thinking, known as rumination, in people with depression. Early trials suggest that this method can improve mental health by altering connections between different parts of the brain. Real-time fMRI neurofeedback, a technique used in mbNF, has effectively lowered DMN activity. These findings indicate that mbNF could be promising for helping at-risk adolescents with repetitive negative thinking. Meanwhile, another group in this trial will receive sham mindfulness-based neurofeedback, serving as a comparator to evaluate the active treatment's effectiveness. ^{2 3 6 7 8}

Are You a Good Fit for This Trial?

This trial is for adolescents who often have repetitive negative thoughts and might be at risk for serious mental health issues. They will be compared to healthy control participants. Specific criteria aren't provided, but typically, trials require participants to meet certain age and health conditions.

What Are the Treatments Tested in This Trial?

Interventions

• Mindfulness-based Neurofeedback
• Sham mindfulness-based neurofeedback

Trial Overview

The study is testing if mindfulness-based neurofeedback (mbNF) can change brain connectivity related to negative thinking in at-risk teens. It's a double-blind trial where participants get either real mbNF or a sham version, along with mindfulness training.

How Is the Trial Designed?

Group I: Mindfulness-based neurofeedback (mbNF) Experimental Treatment 2 Interventions

Participants will: * Complete a brief resting state MRI scan at Visit 2 to assess default mode network connectivity * Receive a 45-minute mindfulness training * Receive two 15-minute sessions of mindfulness-based neurofeedback

Group II: Healthy Control (HC) Active Control 1 Intervention

Healthy control participants will complete a brief resting state MRI scan at Visit 2 to assess default mode network connectivity. They will receive no intervention or comparator.

Group III: Sham mindfulness-based neurofeedback (Sham mbNF) Placebo Group 2 Interventions

Participants will: - Complete a brief resting state MRI scan at Visit 2 to assess default mode network connectivity -Receive a 45-minute mindfulness training -Receive two 15-minute sessions of sham mindfulness-based neurofeedback
