What Researchers Did
Researchers investigated the effects of repeated hyperbaric oxygen exposures on behavioral and physiological measures in 21 elderly patients with cerebrovascular disease or cortical atrophy.
What They Found
After 15 days of twice-daily hyperbaric oxygen treatments, no significant changes were observed in psychological, electroencephalographic, or cerebral blood flow measures among the 8 patients with cerebrovascular disease and 13 patients with cortical atrophy. The study concluded that hyperbaric oxygen had no therapeutic effect in patients with moderate to severe dementia.
What This Means for Canadian Patients
Canadian patients with moderate to severe dementia are unlikely to benefit from hyperbaric oxygen therapy for their condition. Healthcare providers should consider alternative, evidence-based treatments for managing dementia symptoms.
Canadian Relevance
This study has no direct Canadian connection as it was not conducted in Canada nor involved Canadian researchers or participants.
Study Limitations
A limitation of this study is its relatively small sample size of 21 patients, which may limit the generalizability of the findings.
