Trial Summary

What is the purpose of this trial?

This trial tests a new method that combines teaching emotion management skills with a type of brain stimulation. The goal is to help adults who struggle to calm down when upset and have certain mental health conditions. The brain stimulation aims to make it easier for them to learn and use these skills effectively.

Will I have to stop taking my current medications?

You will not have to stop taking your current medications, but you must keep the dose the same throughout the study if you are stable on them for the past 4 weeks. Changes are only allowed in case of a medical emergency.

What data supports the effectiveness of the treatment Neurostimulation + Therapy for Emotional Regulation Issues?

Research shows that repetitive transcranial magnetic stimulation (rTMS) can influence brain areas involved in emotion regulation, potentially helping with emotional issues. Studies have found that rTMS can have mood-elevating effects, especially in conditions like depression, suggesting it might be beneficial for emotional regulation. ^{1 2 3 4 5}

Is repetitive transcranial magnetic stimulation (rTMS) generally safe for humans?

Repetitive transcranial magnetic stimulation (rTMS) is generally considered safe for humans, with most studies showing a reassuring safety profile. However, there have been rare cases of seizures, and guidelines have been developed to ensure its safe use. ^{6 7 8 9 10}

How does the treatment Neurostimulation + Therapy for Emotional Regulation Issues differ from other treatments for emotional regulation issues?

This treatment combines repetitive transcranial magnetic stimulation (rTMS), which uses magnetic fields to stimulate nerve cells in the brain, with emotional awareness training to improve emotional regulation. Unlike other treatments that may focus solely on medication or therapy, this approach uniquely integrates brain stimulation with skills training to target both the neurological and behavioral aspects of emotional dysregulation. ^{11 12 13 14 15}

Eligibility Criteria

This trial is for adults aged 18-55 who struggle with emotional regulation and have been diagnosed with certain mood, anxiety, stress-related, impulse control, ADHD or eating disorders.

People are excluded if they have severe psychiatric conditions like bipolar I disorder or psychosis, substance abuse issues, a low verbal IQ, serious medical illnesses that could interfere with neurostimulation or MRI scans.

Inclusion Criteria

Meets criteria for at least one mood (including Bipolar II w/o current hypomania), anxiety, stressor, OCD, Impulse Control, ADHD, or eating DSM-5 disorder (except exclusionary diagnoses such as severe anorexia). Note: Both current or partial remission of the disorder will be ok for inclusion into the study

I have been in the same psychotherapy or none for the last month and am willing to continue it during the study.

I am between 18 and 55 years old.

Exclusion Criteria

Verbal IQ < 90 on the North American Adult Reading Test (NART)

I do not have any severe illnesses, including serious migraines.

Treatment Details

Interventions

• Active Repetitive Transcranial Magnetic Stimulation (rTMS) (Neurostimulation)
• Cognitive Restructuring (Behavioral Intervention)
• Electrical Scalp Stimulation (Neurostimulation)
• Emotional Awareness Training (Behavioral Intervention)
• Sham Repetitive Transcranial Magnetic Stimulation (rTMS) (Neurostimulation)

Trial Overview The trial tests how well one-session training combining emotion regulation skills with excitatory repetitive transcranial magnetic stimulation (rTMS) over the prefrontal cortex affects brain function and behavior. It compares this combined intervention against each component alone using fMRI imaging before and after treatment to identify changes in neural networks related to emotion regulation.

Participant Groups

Group I: Cognitive Restructuring + Repetitive Transcranial Magnetic Stimulation (rTMS) Experimental Treatment 2 Interventions

Group 1 (G1)- 80 eligible participants will receive training in Cognitive Restructuring (CR). These participants will use CR while receiving rTMS over their individual dlPFC target and will partake in short term and long term follow up testing.

Group II: Cognitive Restructuring + scalp electrical stimulation Active Control 2 Interventions

Group 2 (G2) - 80 eligible participants will receive training in CR. These participants will use CR while receiving scalp electrical stimulation over their individual dlPFC target and will partake in short term and long term follow up testing.

Group III: Emotional Awareness Training + Repetitive Transcranial Magnetic Stimulation (rTMS) Active Control 2 Interventions

Group 3 (G3) - 80 eligible participants will receive emotional awareness training. These participants will receive rTMS over their individual dlPFC target and will partake in short term and long term follow up testing.

Active Repetitive Transcranial Magnetic Stimulation (rTMS) is already approved in Canada for the following indications:

Approved in Canada as rTMS for:

• Major Depressive Disorder
• Obsessive-Compulsive Disorder

Findings from Research

Repetitive transcranial magnetic stimulation (rTMS) is a promising non-invasive brain stimulation technique that can enhance brain excitability and potentially improve conditions like stroke, Parkinson's disease, and depression, as discussed in a 2010 symposium with insights from both animal studies and small clinical trials.

While there is significant interest and some signs of therapeutic success with rTMS, the current models explaining its effects may need refinement to fully understand the underlying mechanisms and outcomes observed in various studies.

Low frequency (LF) rTMS applied to the right dorsolateral prefrontal cortex (dlPFC) enhances emotional and autonomic responses, as indicated by increased heart rate deceleration when viewing negative and neutral images, suggesting it may improve emotional processing.

High frequency (HF) rTMS, on the other hand, appears to diminish the emotional modulation of cardiac responses, indicating that LF and HF rTMS have opposing effects on emotional perception and autonomic function.

In a study involving 18 healthy individuals, slow repetitive transcranial magnetic stimulation (rTMS) applied to the prefrontal cortex did not result in significant changes in emotions such as happiness, irritability, or anxiety.

The study found that slow rTMS did not affect sleep quality either, suggesting that this specific stimulation method may not be effective for mood modulation in healthy individuals.

In a study involving 18 subjects with major depression, repetitive transcranial magnetic stimulation (rTMS) for up to 4 weeks was found to be generally safe, with no significant mean deficits in neuropsychologic function or auditory thresholds.

However, two patients experienced mild high-frequency hearing loss, indicating that while rTMS is safe for most, individual responses may vary and warrant further investigation into long-term safety.

Repetitive transcranial magnetic stimulation (rTMS) is generally safe for older adults with late-life depression, with only 12.4% reporting any adverse events and serious adverse events occurring in just 1.5% of cases, based on a review of 11 studies involving 353 patients.

The most common adverse events were mild, such as headaches (6.9%) and discomfort at the stimulation site (2.7%), although some serious adverse events, including psychiatric hospitalization and increased suicidal ideation, were noted in case reports, highlighting the need for further research to ensure safety in this population.

The study demonstrated that healthy participants could effectively down-regulate activity in the right amygdala using real-time functional MRI (rtfMRI) neurofeedback while exposed to negative emotional stimuli, suggesting a potential method for emotion regulation.

This approach, which involved four training sessions with six participants, indicates that rtfMRI neurofeedback could be a promising tool for treating emotional disorders by targeting the overactive amygdala, which is often dysregulated in such conditions.
