Many sufferers from mold toxicity complain of cognitive deficits including: memory problems, inability to focus (brain fog), and slow reaction times. The addition of hyperbaric oxygen therapy was shown to cause marked improvements in these patients. These improvements were seen in only 10 sessions of hyperbaric oxygen therapy. Moreover, this study revealed that these benefits were seen at only 1.3 ATA (low pressure) and while using oxygen connections closer to room air than the conventionally-used 100% oxygen delivery systems <view study>
