Tal and colleagues used brain microstructure imaging to ask a mechanistic question: can hyperbaric oxygen actually drive new blood-vessel growth and nerve-fiber changes in people with long-standing post-concussion injury?
What the study looked at
Fifteen patients with prolonged post-concussion syndrome (PPCS) from traumatic brain injury received 60 daily HBOT sessions. Imaging used Dynamic Susceptibility Contrast-enhanced (DSC) perfusion and Diffusion Tensor Imaging (DTI) MRI sequences; cognition was assessed with a computerized battery. Treatment began 6 months to 27 years after injury.
What it found
The authors reported imaging changes consistent with angiogenesis (increased cerebral blood flow) and with white- and gray-matter microstructural change, interpreted as nerve-fiber regeneration, alongside cognitive measures.
How strong is the evidence?
A small, uncontrolled imaging study; the structural-imaging findings are mechanistically interesting but not a substitute for controlled clinical-outcome trials. The previous slug labeled this a PTSD study — the verified paper is about TBI/post-concussion patients.
