The methodology for using HBOT to treat autism comes from research on other neurological disorders. Increasing research shows that in autism and other neurological disorders there are areas of the brain lacking in blood flow and oxygen, and that when these areas of the brain are exposed to HBOT the blood flow and level of activity in these portions of the brain returns to normal. Autistic children who have done mHBOT treatments have almost universally benefited to some degree from the treatment.
