What Researchers Did
This review article summarized the existing evidence for various nonpharmacologic treatments for migraine, such as behavioral therapies, exercise, and nutritional supplements.
What They Found
Behavioral approaches and aerobic exercise showed some evidence for migraine prevention. Nutritional supplements, including magnesium, riboflavin, and coenzyme Q10, were found effective in small randomised controlled trials. Conversely, there was no convincing evidence for spinal manipulation, and acupuncture's efficacy remained controversial.
Canadian Relevance
This study does not have a direct Canadian connection.
Study Limitations
The review noted that much of the supporting evidence was old, and more studies are needed using modern diagnostic standards and state-of-the-art trial methodology.
