Hyperbaric oxygen therapy (HBOT) has been shown to be effective in the late chronic stage of strokes by multiple studies. After receiving 40-60 HBOT treatments, one study found that 86% of the patients experienced clinically significant improvements in all cognitive domains. This included memory, executive function, attention, information processing speed, and motor skills(4)
Additional studies report similar findings of improved ADLs (activities of daily living), brain metabolism, and quality of life(5,6). Brain scans showed that the damaged locations of the brain were significantly healed and reactivated in more than half of the patients(6). HBOT improves stroke symptoms by healing brain cells that were initially damaged by the stroke as well as stimulating the growth of new brain cells(4,7).
