Hyperbaric oxygen heals traumatic brain injury and concussion
Hyperbaric oxygen heals traumatic brain injury and concussion
An effective treatment to alleviate symptoms and reverse brain damage
Concussions and traumatic brain injuries can cause debilitating conditions with few treatment options. They result from sports injuries, automobile accidents, birth trauma, stroke, surgery or blast injuries in military service. Approximately 25% of patients with mild TBI suffer from ongoing problems that can last a lifetime without treatment.
Symptoms include memory loss, sensitivity to lights and sounds, headaches, poor concentration, mood changes and slower brain processing. The brain tissue surrounding the injury often contains viable but dormant neurons that have stopped functioning due to insufficient oxygen. HBOT can reactivate these idling neurons by dramatically increasing the oxygen available to the brain, stimulating new growth in damaged tissue and promoting neural stem cell activation.

Clinical evidence for HBOT in traumatic brain injury recovery
Hyperbaric oxygen therapy has demonstrated significant clinical promise in restoring neurological function after traumatic brain injury through multiple evidence-based mechanisms.
Neuroplasticity and cognitive restoration: In the largest published cohort of patients suffering from chronic deficits post-TBI of all severities (BMJ Open), HBOT was associated with significant cognitive improvements. The clinical improvements were well correlated with increased activity in the relevant brain areas, as confirmed by SPECT imaging. Patients with injuries ranging from 0.3 to 33 years prior to treatment showed measurable gains.
Cerebral blood flow and oxygenation: HBOT increases dissolved oxygen in plasma by 1,200%, enabling oxygen to penetrate brain tissue with impaired blood flow. This increased oxygenation reactivates idling neurons and stimulates recovery of metabolic activity in chronically damaged tissue. Research confirms that administering oxygen under pressure increases oxygenation in brain tissues by between 10 and 400 times, even into areas of necrotic tissue.
Angiogenesis and stem cell mobilization: HBOT stimulates the formation of new blood vessels through angiogenesis, restoring blood supply to injured brain regions. It also promotes stem cell reproduction by up to 800%, releasing repair cells that migrate to damaged areas and differentiate into new neurons and supporting cells.
Neuroprotective mechanisms: HBOT increases cerebral blood flow, decreases cerebral edema, maintains the blood-brain barrier, suppresses inflammation, decreases apoptosis and inhibits neuronal death. These combined mechanisms create optimal conditions for neural repair and functional recovery.
Military and veteran outcomes: Studies on US military veterans with TBI show significant improvements in depression, anxiety, post-concussive symptoms and suicidal ideation after HBOT. One study found suicidal ideation reduced by over 80%, demonstrating HBOT's profound impact on both cognitive and emotional recovery after brain injury.
HBOT can treat chronic neurological deficits due to traumatic brain injury (TBI) of all severities
Effect of hyperbaric oxygen therapy on chronic neurocognitive deficits of post-traumatic brain injury patients: retrospective analysis
The average age was 42.7±14.6 years, and 58.4% were men. All patients had documented TBI 0.3–33 years (mean 4.6±5.8, median 2.75 years) prior to HBOT. HBOT was associated with significant improvement in all of the cognitive domains, with a mean change in global cognitive scores of 4.6±8.5 (p<0.00001). The most prominent improvements were in memory index and attention, with mean changes of 8.1±16.9 (p<0.00001) and 6.8±16.5 (p<0.0001), respectively. The most striking changes observed in brain single photon emission computed tomography images were in the anterior cingulate and the postcentral cortex, in the prefrontal areas and in the temporal areas.Case control study: Hyperbaric oxygen treatment of mild anoxic brain injury, persistent post-concussion syndrome and post-traumatic stress disorder
Blast-induced traumatic brain injury (TBI) / anoxic brain injury and post-traumatic stress disorder (PTSD) remain the two most common afflictions of U.S. military service personnel who served in the Iraq and Afghanistan Wars.
HBOT was tested on 30 US military subjects with mild TBI persistent post-concussion syndrome (PPCS) and post-traumatic stress disorder (PTSD) that occurred after 9/11/2001. The results of the study showed significant improvements in neurological exam, symptoms, quality of life, and psychological measures. SPECT imaging also revealed significant improvement after 1 and 40 HBOT sessions, and the effects were sustained at a 6-month follow-up. The study found that HBOT was safe and effective for treating veterans with mild to moderate TBI PPCS with PTSD.Hyperbaric oxygen therapy as a neuromodulatory technique: a review of the recent evidence
HBOT offers significant neuromodulatory potential by affecting key cellular and molecular mechanisms. The most representative molecules and pathways influenced by HBOT include mitochondrial biogenesis and function (enhanced ATP production, increased Bcl-2 expression, and reduced Bax expression), neurogenesis (upregulation of Wnt-3 and VEGF/ERK signaling), synaptogenesis (elevated GAP43 and synaptophysin expression), and anti-inflammatory pathways (reduced TNF-α and IL-6).
Hyperbaric oxygen therapy (HBOT) has recently emerged as a promising neuromodulatory modality for treating several neurological and psychological disorders. Various studies indicate that HBOT can promote brain recovery and neuroplasticity through the modulation of key cellular and molecular mechanisms. HBOT affects multiple primary pathways and cellular functions including mitochondrial biogenesis and function (increased Bcl-2, reduced Bax, and enhanced ATP production), neurogenesis (upregulation of Wnt-3 and VEGF/ERK signaling), synaptogenesis (elevated GAP43 and synaptophysin expression), and anti-inflammatory responses (reduced TNF-α and IL-6). These mechanisms contribute to significant clinical benefits, such as enhanced cognitive function, improved recovery from traumatic brain injury and post-concussion syndrome, and symptom reduction in conditions like post-traumatic stress disorder and fibromyalgia. By influencing these molecular targets, HBOT offers a novel approach to neuromodulation that warrants further exploration. This review discusses the representative mechanisms of action of HBOT and highlights its therapeutic neuromodulatory effects and potential clinical applications across various neurological and psychiatric conditions.Brain injury survivors share their recovery stories

His parents were frantic. Kevin had tried prescription drugs and therapy, which helped some with his systems. However, they did not eliminate the headaches and fatigue or improve his mood. They did not get him up and back to school.
After HBO therapy, Kevin could attend school again and interact with his friends. HBOT head injury treatment made a major impact in recovering Kevin’s cognitive and emotional health and well-being.

She had a severely misshapen head, a tube in her stomach to feed her, and a tube to help her breathe. Tragically, Mara's mother was told her baby would never recover nor respond like a normal child. She had already returned to the hospital twice for complications with her condition. Mara's mother brought her in 5 days a week for hyperbaric oxygen TBI treatment. When Mara finished hyperbarics, her tubes had been removed. She could breathe on her own, and she was able to eat and swallow food like a normal child. HBOT head injury treatment helped Mara be strong enough to sit up and wave bye-bye when encouraged. The nurse in the Pediatrician's office burst into tears of joy when she saw the improvements in Mara's condition.

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 to see if HBOT could help. And, it did! HBOT helped him enough that he stayed in AP math and graduated with honors.
After graduating high school, Jeremy 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.

Elliot was active in sports in high school. During football practice, he had a concussion that turned out to be his second. This one was caused when he collided with another players’ head and helmet.
Elliot didn’t recover from this concussion as he had with the first one. After two months, he stopped going to school. Maintaining a regular schedule just became too difficult given his inability to concentrate and his memory loss. Even reading became too difficult because he had blurry vision.
Elliot came to Bay Area Hyperbarics five months after his concussion with these concerns, but also depression, intermittent fatigue, sleep disturbances, and headaches. His parents tried several different therapies, diet changes, supplements and migraine medications. He was supervised by a psychiatrist and on prescription anti-anxiety meds, plus meds for depression. He was also receiving acupuncture.
It took two months of hyperbaric therapy to heal his brain well enough that he could return to school. Honestly, he seemed like a different person when he left our clinic. He was smiling and walked with a healthy gait. However, he did not return to play football, based on a recommendation from his neurologist.
