Here is another argument that HBOT (Hyperbaric Oxygen Therapy)should be considered a major component of post-concussion care. It has now been shown that lingering symptoms such as headache and cognitive difficulty may be more likely in young people who rest and avoid physical activity following one or more concussions. This is according to a just-released study by Canadian researchers. Clearly, there should be no exposure to additional head injury, but physical activity, it is suggested, may improve blood flow and brain healing. The assumption in that is that blood flow delivers oxygen to the brain. If that is a goal of therapy and healing, is it clear that HBOT is a far more efficient, effective and immediate means of increasing brain oxygen levels that any amount of physical activity. There is no excuse not to use HBOT as soon as possible following a concussion, and to continue until symptoms have resolved. HBOT not only delivers oxygen directly to brain tissue, but it also reduces inflammation, decreases swelling, and reverses damaging metabolic processes that follow brain injury.
