Hi Leslie,
I have not tried this but I do brain-training games on lumosity.com when I can. I watched the 3 minute video, and this looked similar except it gives you brain-wave feedback in addition to feedback on how well you play the game. There may be more to it though. I like these sorts of games because I feel they help me combat my migraine and migraine-medication induced brain fog. That being said, I personally haven't noticed any benefits in reduction of migraines by playing these games, nor have I read any literature on them. They do make me feel sharper overall, though.
I wonder if this could be similar to biofeedback? https://migraine.com/migraine-treatment/natural-remedies/biofeedback/
Biofeedback is sometimes covered by insurance, so that might be worth investigating first.
I would love a headband (perhaps a more discreet one) that would alert me to when an attack was coming on!
Anyway, thanks for sharing this on the forum and it would be interesting to hear from anyone who has tried this.
Lisa
