In the past couple of months, our son Siddhu has been going through hyperbaric oxygen therapy: one of us basically go with him into a high pressure chamber enriched with oxygen, this is supposed to let more oxygen flow into the brain. As an added bonus, my asthma gets better (I think, though I may be imagining that!) Other than the slightly elevated temperature, which on a hot day is not a mild inconvenience, you don't notice anything. Siddhu is so non-chalant, he just watches a DVD or colors his book inside the chamber.

This is a relatively new treatment for autism, and one other parent is doing it with us. There is significant positive change for their son, and Siddhu also has been calmer and more focused recently.
