39 ASD children (35 boys, 4 girls) underwent a ’40 Hour’ intensive course of hyperbaric oxygen therapy (either once daily for 8 weeks or twice daily for 4 weeks) at 1.5 ATA (60 minutes each). The participants were then divided into two age groups: older (over 79 months) and younger (under 79 months). “In younger children under study post-therapy improvements were found for the ATEC Sociability - "Does not imitate", ATEC Sensory/cognitive awareness - "Shows imagination", and ATEC Health/physical/behavior - "Sound-sensitive" items. In older children improvements were noted for ATEC Health/physical/behavior - "Obsessive speech" and CARS emotional response, adaptation to change, and total score” “The results of the present study demonstrate that hyperbaric oxygen therapy is a valuable component of the comprehensive treatment and rehabilitation process in children with autism spectrum disorders.” <view study> Read Less

“Children with autism who received hyperbaric treatment at 1.3 ATA and 24% oxygen for 40 hourly sessions had significant improvements in overall functioning, receptive language, social interaction, eye contact, and sensory/cognitive awareness compared to children who received slightly pressurized room air...” <view study> Read Less

Though hyperbaric oxygen therapy is not an FDA-approved treatment for autism, there are progressively, and exponentially, more autistic families that are seeking out hyperbaric therapy for their children, and some claim amazing benefits. The purpose of this review was to analyze the data and studies and try to help shed more light as to some of the key mechanisms of actions <view study> Read Less

A study coming out of Thailand looked at applying 1.3ATA (low pressure hyperbaric oxygen) to autistic children. They pre-assessed them before the hyperbaric procedure and then re-evaluated them after only 10 sessions. Significant improvements were obtained from only 10 sessions in 75% of the children that participated in this study <view study> Read Less

Over the past few years, hyperbaric oxygen therapy is being used increasingly by doctors and clinicians for its off-label uses, and autism is one of the largest conditions, particularly for lower pressure protocols. It is very well known that autistic children will have much higher levels of inflammation presenting in the brain (neuroinflammation). This study looked at lower pressure protocols and followed markers of inflammation. They found significant improvements with both ambient air and with breathing 100% oxygen, including anti-inflammatory effects. More importantly, they were also able to observe significant clinical benefits and improvements <view study> Read Less
