Multiple studies have found that autism is characterized by cerebral hypoperfusion which correlates with many core features including repetitive,
self-stimulatory, and stereotypical behaviors, and impairments in communication, sensory perception, and social interaction. Hyperbaric oxygen therapy (HBOT) can help overcome cerebral hypoperfusion by providing more oxygen to the brain. Recent studies have shown that children with autism
have neuroinflammation and gastrointestinal inflammation, and HBOT is strongly anti-inflammatory
