Trial Summary

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications. However, if you are on psychotropic medications (drugs that affect your mood or mind), you must have been on a stable dose for the past month to participate.

What data supports the effectiveness of the treatment Accelerated Intermittent Theta Burst Stimulation for Long COVID?

A case report showed that a 30-year-old woman with anxiety, depression, insomnia, and mild cognitive impairment after COVID-19 improved significantly after receiving accelerated theta-burst stimulation over the prefrontal cortex. This suggests the treatment might help with similar symptoms in Long COVID.12345

Is theta burst stimulation safe for humans?

Theta burst stimulation (TBS), including intermittent theta burst stimulation (iTBS), has been studied for various conditions and is generally considered safe in humans. Some studies report minor tolerability issues, but serious side effects are rare.14678

How does the treatment Accelerated Intermittent Theta Burst Stimulation differ from other treatments for Long COVID?

Accelerated Intermittent Theta Burst Stimulation (iTBS) is unique because it uses magnetic pulses to stimulate specific areas of the brain, potentially improving neuropsychiatric symptoms like anxiety and depression associated with Long COVID. Unlike traditional treatments, it is non-invasive and focuses on altering brain activity directly, which may offer benefits for symptoms that are not well-managed by standard medications.12369

What is the purpose of this trial?

The goal of this clinical trial is to test whether a type of rapid outpatient brain stimulation that uses magnetic fields, called accelerated intermittent theta burst stimulation (iTBS), can treat symptoms such as brain fog, depression, and anxiety in patients with Long COVID. The main questions it aims to answer are:* Is iTBS effective and feasible for reducing Long COVID symptoms? We will measure these symptoms using the Symptom Burden Questionnaire.* Are there changes in inflammatory brain chemicals associated with treatment with iTBS? We will be looking at levels of choline in the brain, which is thought to be related to inflammation.Researchers will compare sham versus active forms of iTBS to see if the active group has greater improvement in symptoms.Participants will complete symptom surveys, cognitive tests, and magnetic resonance imaging scans at the beginning, middle, and end of treatment.

Treatment Details

Interventions

  • Accelerated Intermittent Theta Burst Stimulation
Trial Overview The study is testing accelerated intermittent theta burst stimulation (iTBS), a rapid outpatient brain stimulation technique using magnetic fields. It compares active iTBS with sham treatment to see if it reduces Long COVID symptoms and affects brain inflammation markers.
Participant Groups
2Treatment groups
Experimental Treatment
Placebo Group
Group I: Active accelerated iTBSExperimental Treatment1 Intervention
Participants will be assigned to receive fMRI-guided iTBS (5 days, 5 sessions/day) to the left dorsolateral prefrontal cortex (dlPFC) during the sham-controlled phase. Each participant is invited to undergo 25 more sessions (5 more days) of open label, unblinded active accelerated fMRI-guided iTBS to the left dlPFC.
Group II: Sham accelerated iTBSPlacebo Group1 Intervention
Sham stimulation is delivered using the same coil as active stimulation, producing an equivalent sound, however it is shielded so that no effective magnetic field reaches the participant's brain. To blind participants to active versus sham condition, a mild electrical skin stimulation that has no brain effects is delivered simultaneously with iTBS at the scalp to both active and sham groups, creating the same sense of skin sensation in both groups.

Findings from Research

In a study involving 12 subacute stroke patients, prolonged transcranial magnetic stimulation (iTBS1200) was found to be safe and well-tolerated, with no significant adverse effects reported.
Patients receiving iTBS1200 showed measurable improvements in stroke severity and upper extremity function shortly after treatment and at 60 days post-stroke, suggesting potential benefits that warrant further investigation in larger trials.

In a study involving 36 multiple sclerosis patients, intermittent theta burst stimulation (iTBS) significantly improved manual dexterity, as shown by faster completion times in the nine-hole peg test and increased performance in the Box and Block Test.
However, iTBS did not have a significant impact on hand motor imagery abilities, indicating that while it can enhance physical tasks, it may not affect cognitive aspects of motor function.

In a study of 27 participants, a prolonged intermittent theta burst stimulation (piTBS) protocol using 1,800 pulses showed limited effectiveness for major depressive disorder, with only 18.2% of participants achieving a response and 9.1% reaching remission.
Safety and tolerability were concerns, as 18.5% of participants experienced issues, suggesting that while piTBS is a promising approach, further research is needed to optimize its parameters and improve outcomes.
