Hyperbaric Oxygen Therapy (HBOT) uses oxygen therapeutically for a wide variety of conditions in which tissues have been damaged by varying degrees of oxygen deprivation. When oxygen is under pressure, it can bring about positive and permanent changes in the cellular DNA and the surrounding tissues. Research has recently demonstrated that HBOT is helpful for a variey of brain disorders, including Autism Spectrum Disorders, ADD, PDD, ADHD. The improvements reported are found in cognitive ability, socialization, sleep, calmness, reduced stimming, and increased language use. Most parents report improvements in their children within the first 20-40 sessions.
