Traumatic brain injury (TBI) is far more common than most people realize — millions of Americans live with the aftereffects of concussions and head injuries, and for a large share of them the symptoms never fully go away.
These “persistent post-concussion” problems (headaches, brain fog, poor sleep, anxiety, dizziness, loss of smell) can quietly derail careers, relationships, and independence for years, and they carry an enormous societal and financial cost in lost productivity and ongoing care.
What makes this study important is that it tackled these lingering symptoms head-on with a rigorous design. In a double-blind randomized trial, 47 people (40 with TBI) received either 40 real HBOT sessions at 1.5 ATA over 12 weeks or 40 sham sessions.
The HBOT group improved almost three times as much on a standard neurobehavioral symptom scale (a 10.6-point gain vs. 3.6), with additional benefits for smell, anxiety, sleep, and balance.
When participants were later offered a second 40-session course, they improved further at 12 months — leading the authors to suggest that 80 sessions may work even better than 40 for long-term brain-injury recovery.
The takeaway for patients: meaningful improvement may be possible even long after the injury, if enough sessions are completed <
