Low Frequency Right Dorsolateral Pre Frontal Cortical Repetitive TMS for Bipolar Depression
Canada80 participantsStarted 2025-05-27
Plain-language summary
The purpose of this trial is to conduct an adequately powered clinical trial of once daily LFR for individuals diagnosed with treatment-resistant BD-DE who have not responded to iTBS or sham treatment applied to the left DLPFC. This work will develop the evidence supporting the use of LFR rTMS for individuals with treatment-resistant BD-DE who currently have limited treatment options to alleviate their suffering. Participants will come for 30 days of LFR, with a 6-week follow-up period. Symptoms of depression (for determining treatment efficacy) and mania (for determining treatment safety) will be assessed using the 17-item Hamilton Rating Scale for Depression (HRSD-17) and the Young Mania Rating Scale (YMRS) every five treatments during the treatment course, and at 1 week and 6 week after treatment completion.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
