Yes, but you'd need your own equipment, probably $1k-1.5k investment including the software. Some guy I believe in Australia makes portable "pocket neurobics" systems (pendant, etc.) which have a good reputation and are on the lower end of the price scale. Sometimes you can also find practitioners who will rent you equip. So then you get the best of both worlds, with them being able to get you started and show you what to do, and then you training yourself at home for lower cost. I know a guy who built his own 2-channel amp from open source schematics, etc. (Open EEG, is I think the name of the project). So if you have electronics knowledge and are ambitious that might also be an option for some ppl.
Not saying any of this is easy - what with ME/CFS ever is? - but it's definitely possible. After I also once had a complete remission from EEG NF for almost a week, I'm convinced that dysregulated neurology is the lynchpin for many ME/CFSers, especially those on the dysfunctional HPAA end of the spectrum. When that's corrected, the immune system seem to fall more or less into line, also. A larger database of ME/CFS brains could probably really help identify the problem better, as most comparisons are to "normal" brains, and even people w/ADD, depression, etc. who typically go for EEG NF likely still don't have ME/CFS or ME/CFS brainwave patterns.
