Autism

Definition and Causes

Autism, or autism spectrum disorder (ASD), is a range of developmental or biomedical disorders that affect many parts of the brain. Symptoms begin in childhood and include a variety of social, communication, and behavioral impairments or differences.

Autism affects 1 in 88 children in the US, five times more boys (1 in 54) than girls (1 in 252). [CDC, 2012]

Scientists little understand how or why autism occurs. Possible causes have become the subject of heated debate among medical practitioners and patient advocacy groups. Vaccines, heavy metal poisoning, wheat and dairy diet, and oxygen insufficiency have all been eliminated from serious consideration. Strong genetic ties have been firmly established. Most research today focuses on identifying specific genes, environmental triggers, infections, brain development, and problems before, during, and after childbirth.

Treatment with Hyperbaric Oxygen Therapy

Hyperbaric oxygen therapy (HBOT) and especially so-called mild HBOT (inflatable bags) are widely used off-label to treat autism at independent clinics and at home. Proponents hypothesize that HBOT enhances or restores neurologic function by oxygenating the brain or flushing toxins from cells, blood, tissues, and organs. The clinical evidence in the peer-reviewed medical literature does not support this physiologic rationale or the use of HBOT to treat autism spectrum disorder. The FDA mentions autism specifically in its Consumer Update about the potential dangers of using HBOT to treat off-label conditions.

hyperbariclink commentary

People living with autism, beware. Perhaps no patient community today is so beset by healthcare fraud and quackery. Hyperbaric oxygen therapy has gotten caught up in a powerful movement away from evidence-based practice and toward alternative therapists promising miracle cures. Their claims are as wild as their HBOT is mild. What thin evidence we have on HBOT for autism (see Rossignol, et al, 2012) is fraught with contradictions and undercut by investigator bias. Thankfully, patients and families can turn to a growing network of trustworthy autism educators and caregivers. The first signs of ASD typically emerge before age 3. Early diagnosis is the key to success with evidence-based autism therapy, including applied behavior analysis (ABA) and other proven methodologies.
