What Researchers Did
Researchers pooled data from 13 studies involving 958 Parkinson's disease patients to compare hyperbaric oxygen therapy (HBOT) against standard drug treatment for motor and non-motor symptoms.
What They Found
Patients who received HBOT were 3.18 times more likely to show treatment success than those on standard drugs alone (95% CI: 1.60–6.33). Motor function scores on the UPDRS III improved significantly (mean difference of -2.96 points), and cognitive scores on the MoCA improved by a standardized mean difference of 0.65. Sleep quality also improved markedly, with Pittsburgh Sleep Quality Index scores dropping by an average of 2.52 points.
What This Means for Canadian Patients
Parkinson's disease affects roughly 100,000 Canadians, and many struggle with both movement problems and non-motor symptoms like sleep disorders, memory issues, and depression. This meta-analysis suggests HBOT added to standard treatment can meaningfully improve all of these areas, not just movement. Canadians with Parkinson's who have not responded fully to medication may have a case to discuss HBOT as a complement to their existing care plan.
Canadian Relevance
No direct Canadian connection identified.
Study Limitations
Most included studies came from Chinese databases and had variable HBOT protocols, making it difficult to determine the ideal pressure, session length, or frequency for Parkinson's patients.
