Rossignol et al (2009) concluded that "[g]iven the positive findings of this study, and the shortage of proven treatments for individuals with autism, parents who pursue hyperbaric treatment for their child with autism can be assured that it is a safe treatment modality at the pressure used in this study ( atm), and that it may improve certain autistic behaviors. Further studies are needed by other investigators to confirm these findings; we are aware of several other planned or ongoing studies of hyperbaric treatment in children with autism. However, in light of the positive results of this study and those of several previous studies, the use of hyperbaric treatment appears to be a promising treatment for children with autism".
