Autism Spectrum Disorder (ASD) is a complex neurological and developmental disorder that affects an individual's social interactions, communication skills, range of interests, and behavioral patterns. Symptoms of ASD usually appear in early childhood and affect their functioning in school, work, and daily life.
Although ASD is lifelong, early diagnosis and appropriate treatment and intervention can significantly improve symptoms and improve quality of life. Treatment includes behavioral intervention, language and occupational therapy, and educational support aimed at helping individuals develop social skills, communication skills, and independent living skills. Family and community support is essential to improving the quality of life of people with ASD.
Hyperbaric oxygen therapy (HBOT) is a medical treatment that involves exposing a patient to pure oxygen in a pressurized chamber. The therapy works by increasing the amount of oxygen dissolved in the blood, which in turn can enhance the body's natural healing processes and improve the delivery of oxygen to tissues that may be compromised due to injury, infection, or certain medical conditions.
Some autism may be related to brain hypoxia during the fetal period or early childhood. HBOT promotes oxygen penetration into hypoxic tissues by increasing blood oxygen concentration (especially under high pressure), stimulating nerve cell development and damage repair. Children's forebrain development is not yet complete at the age of 7-8 years old. HBOT may support neuroplasticity by enhancing cerebral blood flow and oxygen supply.
Children with autism are often accompanied by intestinal flora imbalance (such as overgrowth of anaerobic bacteria) and constipation. HBOT inhibits the reproduction of anaerobic bacteria, promotes intestinal peristalsis, improves flora balance, and reduces toxin absorption. In addition, HBOT may help the excretion of heavy metals (such as lead and mercury) by accelerating metabolism and rerelievingymptoms caused by metabolic disorders.
Children with autism often have food allergies and chronic inflammation. HBOT exerts anti-allergic and anti-inflammatory effects by reducing oxidative stress and inhibiting pro-inflammatory factors (such as TNF and IL-6), reducing the negative impact of immune abnormalities on the nervous system.
Some autism is believed to be related to viral infection (such as viral encephalitis). HBOT can inhibit viral replication, relieve cell edema after infection, and promote functional recovery.
Short-term safety: Under standardized operation, short-term treatment in a hyperbaric oxygen chamber (HBOT) is generally considered safe, but medical guidance must be strictly followed.
Potential risks:
Common side effects: ear pressure discomfort (similar to flying), temporary blurred vision, and fatigue.
Serious risks (rare): oxygen toxicity, barotrauma (middle ear or lung damage).
Contraindications:
Uncontrolled epilepsy, severe lung disease (such as pneumothorax), patients in the acute stage of otitis media.
Common short-term side effects (mostly relieved):
Ear pain (can be relieved by swallowing, pinching the nose, and blowing air).
Children with claustrophobia may resist confined spaces.
Long-term risk controversy:
Excessive oxygen free radicals may damage cells (lack of long-term data for children with autism).
US FDA warns: Non-medical-grade oxygen chambers have safety hazards.
Parents' response suggestions:
Observe the child's reaction during treatment and communicate with the operator promptly.
Avoid continuous high-frequency treatment (such as multiple times a day).
Age limit:
There is no uniform standard, but the child's cooperation needs to be considered.
Most institutions accept children over 3 years old, and parents must accompany them into the chamber.
Special considerations:
Young children (<5 years old) may affect the treatment effect due to fear.
Some institutions provide "game-based adaptation training" to help children desensitize.
