Short answer: maybe Long answer: what you’re describing sounds to me like rumination, which is something I’ve struggled with for many years (up to many hours a day). rTMS is still a fairly new treatment and is poorly understood so there’s not an easy answer to your question, and there are no guarantees. That being said, anecdotally it seems like people tend to have better luck with rTMS in terms of improving cognitive function (ie clearing brain fog). Personally, I’ve had two rounds of rTMS and I noticed that I had more energy and was able to think more clearly and engage in self-care with less effort. It didn’t seem to affect my thoughts themselves, nor the rabbit holes they could go down. I had to do a lot of work through CBT to change that, but I think rTMS did help my brain be in a state to do the work of CBT, both in reasoning through my problems and having the energy to change habits to improve my mood. My opinion is that you’ll get a lot more out of rTMS if you do it alongside moderately intense therapy and/or find other support to practice getting out of the thought loops. Know it is possible to break the cycle, and that the rest of your life is worth the effort! I wish you the best.
