My 7 year-old Asperger/high functioning autistic son has been doing Hyperbaric Oxygen therapy for 2 1/2 months and completed 65 dives so far. I wasn't sure if it would help him or show the signs of improvements fast for all the stories I read and heard about HBOT were for lower functioning and younger autistic kids. But we saw positive changes almost as quick as after 1 dive! His areas of improvements include sensory issues, sleep, some social and language skills. He also improved on gross motor too. HBOT is giving us new hopes!
I have posted this same message under AS and HBOT. I hope you look into it and find out more about how it can help your children. Best wishes.
