Reflections on the neurotherapeutic effects of hyperbaric oxygen

Traumatic brain injury (TBI) and stroke are the major causes of brain damage and chronic neurological impairments. There is no agreed-upon effective metabolic intervention for TBI and stroke patients with chronic neurological dysfunction. Clinical studies published this year present convincing evidence that hyperbaric oxygen therapy (HBOT) might be the coveted neurotherapeutic method for brain repair. Here we discuss the multi-faceted role of HBOT in neurotherapeutics, in light of recent persuasive evidence for HBOT efficacy in brain repair and the new understanding of brain energy management and response to damage. We discuss optimal timing of treatment, dosage, suitable candidates and promising future directions.
