What side effects are associated with this type of intervention?

Common treatments for depression, such as TMS and tDCS, generally have mild side effects. For TMS, side effects can include scalp discomfort, headaches, and lightheadedness, but serious adverse events are rare. tDCS may cause mild tingling, itching, or redness at the site of stimulation. Traditional antidepressants, such as SSRIs, can cause nausea, weight gain, insomnia, and sexual dysfunction. It is important to discuss these potential side effects with a healthcare provider to determine the most appropriate treatment.

What prior FDA approvals exist?

Transcranial Magnetic Stimulation (TMS) and Transcranial Direct Current Stimulation (tDCS) are neuromodulatory treatments that have been studied for their efficacy in treating depression. TMS, which involves the use of magnetic fields to stimulate nerve cells in the brain, has been FDA-approved for the treatment of major depressive disorder, particularly in patients who have not responded to traditional antidepressant medications. tDCS, which uses direct electrical currents to modulate neuronal activity, is still under investigation and has not yet received FDA approval for the treatment of depression. These treatments offer alternative options for patients with treatment-resistant depression.

What other types of research exist?

Promising novel alternatives to TMS or tDCS for depression patients include Vagus Nerve Stimulation (VNS), Deep Brain Stimulation (DBS), and Electroconvulsive Therapy (ECT). VNS has shown positive outcomes in treatment-resistant depression, while DBS is being investigated for its potential in modulating brain activity in severe cases. ECT remains a robust option, particularly for treatment-resistant cases, with ongoing advancements in its application and safety.

Summary

This trial will study how depression affects the ability to make decisions, by looking at how different regions of the brain impact difficult choices. TMS will be used on participants to study this.

Who is the study for?

This trial is for English-speaking adults with no history of mental illness. Participants should be able to complete an MRI scan and have no one in their immediate family with a history of seizures.Check my eligibility

What is being tested?

This study determines how brain stimulation affects decision-making. It involves game-like tasks performed while undergoing Transcranial Magnetic Stimulation (TMS) or Temporal Interference stimulation (TI), focusing on the cingulate cortex's role in cognitive control during challenging choices.See study design

What are the potential side effects?

Potential side effects from TMS/TI may include discomfort at the stimulation site, headache, lightheadedness, or seizures (rare). There also might be temporary changes in thinking patterns or mood.

Other Research

Transcranial Magnetic Stimulation (TMS) and Transcranial Direct Current Stimulation (tDCS) are neuromodulation techniques used to treat depression by altering brain activity. TMS uses magnetic fields to induce electrical currents in specific brain regions, such as the dorsolateral prefrontal cortex, which is often underactive in depression. This stimulation can enhance neural activity and improve mood regulation. tDCS, on the other hand, delivers a low electrical current through electrodes placed on the scalp, modulating neuronal excitability and connectivity. These treatments are important for depression patients because they offer non-invasive options that can target specific brain areas involved in mood regulation, potentially providing relief when traditional pharmacotherapy is ineffective.
