Hyperbaric oxygen therapy autism claims, in plain terms.
You will find clinics online that promote hyperbaric oxygen therapy for autism. Some describe gains in speech, eye contact or behavior. It is natural to want to know whether those stories hold up, especially when you are already juggling therapies, school plans and waitlists here in Brevard County.
Here is the short answer. Controlled trials have not shown that HBOT improves the core features of autism. Major pediatric and FDA sources do not support HBOT as a treatment for autism, and Suntree Hyperbaric Center does not offer HBOT as a treatment for autism.
What the FDA says.
The FDA has published a consumer update about hyperbaric oxygen therapy. It cautions that HBOT has not been cleared for a list of conditions that are sometimes promoted online, and autism is on that list. The agency encourages people to check claims carefully and talk with their doctor. You can read the update on the FDA website.
What controlled trials found.
A 2009 multicenter trial led by Dr. Daniel Rossignol randomized 62 young children to mild pressure with slightly raised oxygen or to a near-normal-pressure control. Physician ratings of overall functioning improved more in the treatment group. It was a positive result, and it drew a lot of attention.
Later trials did not confirm it. A 2010 randomized trial by Dr. Doreen Granpeesheh used 80 sessions at similar settings and found no meaningful difference from the control group. A 2012 trial by Dr. Monthida Sampanthavivat used full HBOT at 1.5 ATA with 100 percent oxygen against a sham in 60 children and also found no significant difference.
A 2016 Cochrane review concluded there is no evidence that HBOT improves core or associated symptoms of autism, and noted that minor ear barotrauma can occur. A 2017 review for Canadian family physicians reached a similar conclusion.
Why promising stories and trial results differ.
Children with autism grow and change, often in bursts. Many are in speech, occupational or behavior therapy at the same time. When a family invests time and hope in a new approach, it is natural to notice progress. Sham-controlled trials exist to separate those real changes from the effect of the chamber itself.
None of this means a parent was wrong to look. It means the best available evidence points toward therapies with stronger support, chosen with your child's care team.
Start with your child's pediatrician.
Any decision about a child's care should involve the pediatrician or a developmental specialist who knows your child. They can talk through what is working, what is new in the research, and which services in the Space Coast area may be a good fit.
HBOT also carries risks for children, including ear pain and barotrauma, sinus problems, and anxiety in an enclosed space. If you have questions about HBOT in general, you are welcome to call the team in Rockledge. We will answer plainly and point you back to your child's doctor.
If you call the center.
Parents sometimes call after a friend or an online group mentions HBOT. You are welcome to. The team will explain how a hyperbaric chamber works, what the autism trials found, and why we do not offer HBOT for autism. We will not try to sell you sessions for your child.
You can read about the Suntree team, see how HBOT works at the center, or send a question through the contact page. Bring what you learn to your child's pediatrician so the decision stays with the people who know your child best.
