Hyperbaric oxygen has an auxiliary therapeutic effect on cerebral palsy. The treatment of cerebral palsy must be combined with medication, which mainly nourishes the nerves, and some rehabilitation therapy can also be carried out, which should be carried out under the guidance of experts specializing in children’s rehabilitation. Hyperbaric oxygen has an auxiliary therapeutic effect on cerebral palsy, mainly through the inhalation of oxygen at high pressure, which can activate brain cells, promote the growth of newborn small blood vessels, reduce the resistance of blood vessels, and promote the growth of neural axons, so as to improve the brain function and restore the brain function through these aspects. Hyperbaric oxygen not only has an auxiliary therapeutic effect on cerebral palsy, but also has an auxiliary therapeutic effect on other brain dysfunctions caused by various reasons, such as cerebrovascular disease, multiple sclerosis, and other diseases.
