I've tried both, HBOT about a year ago, and EEG neurofeedback over the past few months. Their aims are entirely different, HBOT seeking to restore generally neuronal health by increasing oxygen and blood flow, and neurofeedback seeking to change the brains actual functioning by promoting "positive" brain wave activity and inhibiting "negative" activity (random spikes, etc,).

I did 40 sessions of HBOT, and while I did feel somewhat better by the end, I honestly think this had more to do becoming involved in coaching my old high school cross country team, which did a lot to lift my spirits. In hindsight, I regret spending the money on HBOT, but that's just my experience. The facility was very close to where I was living, and I thought I'd give it a try. Perhaps I would've seen further benefits had I done more than 40 sessions.

I've done 25ish sessions of neurofeedback, starting this past March. I wasn't seeing much of a change by late April, but the practitioner tried a different program (something called synchrony, which actually tries to promote certain brainwaves, rather than simply showing your brain through feedback what it's doing. After a couple sessions i really was feeling better than I had in a while, but then had a head bump on a water balloon that seemed to affect me, and the same program failed to elicit the previously positive results.

I stopped going at the practitioner's suggestions, but resumed just this week because she recieved an updated program that allows here to pick up lower brain wave frequencies, something the clinical director of the neurofeedback "camp" she's in thinks would be helpful. I've only had one session, and had that "close-call" head bump I posted about earlier muck things up a bit, so I don't have much to report.

So, all in all, neither has been extremely helpful for me, but I'm still glad I tried. Something has to help eventually!
