Do you or anybody else have any resources to share regarding such training? I suffered a concussion 5 years ago and two more shortly after, and I still suffer from regular dizziness due to sunlight / busy environments and after too much screen time. It has taken away much of the joy of my twenties. Thank you.
Unfortunately I don't know anything online, but I would suggest seeking out sports medicine/physiotherapy folks who work with your local concussion-heavy athletes (snow sports, mountain biking, etc). Good luck!
