What Researchers Did
Researchers investigated the effect of hyperbaric oxygen therapy on cluster headache attacks in a small group of patients, comparing it to a placebo.
What They Found
Six out of seven (85.7%) patients with episodic cluster headache experienced an interruption of their attack after hyperbaric oxygen therapy, while a placebo had no effect in six other patients. Among the six responders, three had their florid period of cluster headache interrupted, and the other three remained pain-free for 3 to 6 days.
Canadian Relevance
This study has no direct Canadian connection as it was not conducted in Canada or by Canadian researchers.
Study Limitations
A significant limitation of this study is its very small sample size, which restricts the generalizability of the findings.
