Jeremy is a high functioning big data management engineer in Silicon Valley. He loved surfing, mountain biking, and taking his dog with him. Jeremy had a history of head injuries from sports,including years of soccer headers, football injuries and mountain biking accidents. Jeremy had come in to Bay Area Hyperbarics during high school when he found he had difficulty keeping up in his AP math classes. He was thinking of dropping out of AP math but his mother brought him in to us for HBOT. HBOT was able to help him enough that he stayed in AP math and graduated with honors. Jeremy graduated high school and went on to a prestigious university to become an engineer and linguist. Eleven years after we first saw him, Jeremy brought himself into our clinic for a second time. He was having problems keeping up with the high demands of his job. He said he had to maintain concentration on many variables at the same time while solving complex problems. He feared he was having some days where he just could not perform up to his expectations. He said he needed more focus, better memory and more energy as he also had bouts of fatigue. He was treated using the Haddany study protocol (see the study cited above). Jeremy came back to visit us after finishing his HBOT treatments. He told us he was extremely pleased with his ability to perform now with greater ease, much more quickly, and he finds that answers come to him quicker. He says his energy has improved, not only at work, but also with his mountain biking.
