What Researchers Did
Researchers identified recoverable brain tissue in three patients using SPECT imaging and increased cerebral oxygenation under hyperbaric conditions.
What They Found
They found that hyperbaric oxygen therapy frequently resulted in permanent improvements in cerebral blood flow and metabolism. This reoxygenation correlated with clinical evidence of benefit, especially with continued therapy, in the three patients studied.
Canadian Relevance
This study has no direct Canadian connection.
Study Limitations
A significant limitation of this study is the very small sample size of only three patients.
