What Researchers Did
Researchers conducted a systematic review to evaluate the use of hyperbaric oxygen treatment (HBOT) for individuals with autism spectrum disorders (ASD).
What They Found
The review found that studies of children with ASD reported positive changes in physiology and behavior from HBOT, including improved cerebral perfusion and decreased inflammation markers. Most studies noted improvements in several behavioral domains, with HBOT generally well tolerated and having minimal adverse effects. Higher frequency HBOT sessions (e.g., 10 vs. 5 per week) often led to more significant improvements.
What This Means for Canadian Patients
While some studies suggest hyperbaric oxygen treatment (HBOT) may offer physiological and behavioral benefits for individuals with autism spectrum disorders, its routine use is not yet established. Canadian patients and their families should discuss all treatment options, including HBOT, with their healthcare providers to understand potential benefits and risks.
Canadian Relevance
This systematic review does not have a direct Canadian connection.
Study Limitations
A significant limitation was that many reviewed studies lacked control groups, and the two controlled trials reported conflicting results.
