Every few years, the European Committee for Hyperbaric Medicine (ECHM) publishes its recommendations concerning the clinical indications for hyperbaric oxygen therapy (HBOT). According to Kot J. Mathieu D. (2011) who wrote the most recent recommendations:
“Currently there is no clear rationale for HBOT in autism based on clinically proven pathophysiological mechanisms. The few studies on the use of pressurised environments (not always compatible with the definition of ‘hyperbaric oxygen therapy’) for autism have serious methodological limitations. Therefore, autism should remain as a non-accepted indication for HBOT. HBOT should be used only within the framework of an ethically approved clinical trial.”
