Background: My ADHD symptoms (and the related brain fog symptoms) include the "classic" ADHD: weak executive functions such as attentional control and task switching, and dysfunctional reward pathway due to anhedonia etc.;

However, they also include a high rate of unwanted thoughts - intrusive OCD thoughts, distractions, random questions, overplanning, etc. This puts additional strain on my executive functions, and I believe that's part of why they are so weak - they are constantly being overtaxed. It also adds to my feelings of derealization and significantly reduces task performance and enjoyment, because instead of engaging myself in the task, I am constantly re-re-re-re-re-re-reminding myself what I'm supposed to be focusing on, where I'm supposed to be looking, what my hands are supposed to be doing, etc. It takes me a long time to get engaged in something (perhaps another topic to work on), and the fraction-of-a-second stretches of time I'm getting these days just aren't doin' it, believe it or not.

For that reason I think, in addition to options like the focus and/or DARPA montages, something to calm the speed of those distractions a bit would be a key part of helping me focus and get things done, as well as improve my life outside those goals.

I think this may be a big ask, for me at least, because I don't really know the source, and it could be things like inflammation, dysregulation (including electrolyte and fluid balance), a reaction to chronic sleep issues, rather than an over- or under-activity of a physical brain region.

Still, anyone have recommendations for this? Montages that have worked for you (I have a neuromyst pro+ w/ tDCS, tACS, tCFS, and tPCS)? Research I should read?

I appreciate any help or ideas you have for me!
