Hyperbaric Oxygen for Autism: New Systematic Review of the Medical Literature

For anyone interested in the use of hyperbaric oxygen to treat children with autism, we note the publication today of a simple but helpful systematic review in the online open-access journal Medical Gas Research, by Ahmad Ghanizadeh, Director of Research Center for Psychiatry and Behavioral Sciences at Shiraz University of Medical Sciences in Iran. From today's abstract:
The electronically [sic] search resulted in 18 title of publications. Two studies were randomized, double-blind, controlled-clinical trials. While some uncontrolled and controlled studies suggested that HBO therapy is effective for the treatment of autism, these promising effects are not replicated. Therefore, sham-controlled studies with rigorous methodology are required to be conducted in order to provide scientific evidence-based HBO therapy for autism treatment.
Ghanizadeh's findings support the prevailing view of the evidence-based medical community. Even the two supposed randomized controlled trials (RCTs) he identifies do not, in our view, support the practice, except in the course of clinical investigation. Nor do the eight studies listed on show much promise of answering the important questions. Look for a quick update of our autism page in the weeks ahead.
