Hyperbaric Oxygen Therapy (HBOT) is an experimental treatment for Autism Spectrum Disorder (ASD) that involves breathing concentrated oxygen in a pressurized chamber. While some studies and many parents report improvements in behavior and communication, its effectiveness remains a subject of significant medical debate. 

​

Theory and Potential Benefits

Proponents of HBOT for autism suggest that increasing oxygen flow to the brain can address underlying physiological issues: 

• Reducing Neuroinflammation: Increased oxygen may help "calm" inflammation in the brain, which is linked to certain autistic behaviors.

• Improving Cerebral Perfusion: Some research indicates that children with ASD have lower blood flow to certain brain regions; HBOT aims to increase this flow.

• Enhancing Cellular Function: It may improve mitochondrial function and promote the repair of damaged neural tissues. 

  ​

Reported clinical improvements from some studies include: 

• Socialization: Better eye contact and increased engagement with family.

• Communication: Improvements in receptive language and verbal skills.

• Behavior: Reductions in hyperactivity, irritability, and repetitive behaviors. 

​

Safety and Side Effects

• Sensory/Psychological Stress: Sitting in a confined chamber for 60–90 minutes can cause anxiety or claustrophobia, particularly for children with sensory sensitivities.
