Efficacy of Hyperbaric Oxygen in Neurological Disorders

This review examines the therapeutic role of hyperbaric oxygen therapy (HBOT) as a neuromodulatory tool for treating various brain disorders. The text explains that by saturating blood plasma with supraphysiological oxygen levels, HBOT can restore mitochondrial function, reduce swelling, and trigger regenerative genetic pathways. While meta-analyses suggest significant cognitive and motor benefits for chronic traumatic brain injury, Alzheimer’s, and Parkinson’s disease, the evidence remains inconclusive or negative for conditions like multiple sclerosis, cerebral palsy, and acute stroke. A major point of academic contention involves the "sham" debate, where critics argue that low-pressure control groups are actually receiving a biologically active dose of oxygen. Ultimately, the source highlights that while HBOT is not a universal cure, it offers a promising biological intervention for specific chronic neurological repairs when administered under optimized safety protocols.
