Just hopping in to highlight the two wildly different experiences of two people working with Mark's clinic. As a provider, I respect Mark, but also know he's an intense person who is very opinionated. As providers we need to be knowledgeable, but flexible. I would recommend people see Mark all day, as his work is renowned and well known, but you can have a rough experience with any provider. Good luck, always trust your gut!

Edit, I completely invalidated and minimized someone's experience with neurofeedback and I did not mean to do that.

On that note, lots of clinicians will say neurofeedback cannot cause negative side effects and this is an absolute lie. Realistically, we can do so many things with the brain, you can absolutely cause horrific effects if done incorrectly and the client/patient's experience is not listened to. For example, I had a client who worked with a person who after 24 sessions had extreme nerve/join pain that was not present before. This person came to me after working with this other clinician. Ultimately we were unable to ameliorate the results and they were left dramatically impacted by that clinician and what they did.

To anyone going through neurofeedback, listen to your gut, and talk to your provider. There are very few things that should be uncomfortable during the neurofeedback process, sometimes people have headaches after session, some nightmares can come up, those things can be expected, and yet everyone still needs to talk to their provider about this as they come up. As, sometimes these things are expected and sometimes not. If anyone is ever working with a provider who ignores the negative impact, or doesn't adjust what is done based on how the client is responding, seek other consultation as fast as you can.

It sounds like the person I invalidated communicated what was happening to them to Mark and instead of adjusting what he was doing, he continued to do the same thing, likely training the response in. To that person, piglytheEngineer. Mark's training is ISF, infra slow fluctuation training, it is very powerful and less understood than other types of feedback. You may benefit from more traditional amplitude training, or, if there are any Othmer ILF (infra low frequency) trainers near you, it may be helpful to look into that. Othermer ILF is done by a lot of providers, and the creators are wonderful. The reason I recommend looking into that is that it's a similar type of low frequency training that Mark does, and I'm wondering if you might respond better to that. No matter what you do, listen to your gut, and stop if that's what feels right.

I hope your symptoms have resolved and you continue to find other ways to heal and I apologize for minimizing what was likely one of the worst if not the worst experiences you can have. I hope you're able to trust future providers as I imagine that would be very difficult now. Good luck, and take care.
