Hyperbaric Oxygen Therapy for Autism
The moment a normal child concentrates on an activity or delivers speech, the brain is performing extra work and there is an increase in blood flow to the brain which allows delivery of more oxygen and glucose, supplying the brain cells their required energy to perform their task.
A number of studies have shown that the opposite happens in autistic children. These children have a decreased blood flow to start with, so when their brain is attempting to execute a task, like generating speech or focusing, their blood flow does not increase providing brain cells the needed oxygen and glucose.
This evidence of damage is a result of impaired oxygen delivery resulting from hypoperfusion.
Brain hypoperfusion is simply decreased blood flow to the brain. There are several studies in the medical literature demonstrating hypoperfusion in autistic children. Studies have also shown that the hypoperfusion generally worsened with the age of the child, getting more profound in older children. The diminished blood flow can be viewed with a clear connection to several core autistic symptoms (behavior).
