About
Migraine is a widespread, debilitating, chronic pain disorder and a major public health challenge. Most conventional, pharmaceutical treatments fail to give satisfactory long-term relief and their repeated use can have important side effects. This project involves implementation of substantial dietary changes in adults with migraine. Our goal is to test the hypothesis that a causal relationship exists between migraine symptoms and the amount and proportions of foods consumed containing defined amounts of polyunsaturated fatty acids.
Significant findings supporting the hypothesis will lead to a major shift in both prevention and management of migraine and other chronic pain disorders. Emphasis is on low-cost, health improvement strategies utilizing specific dietary modifications for pain management, based on solid clinical research evidence.
Full description
Episodic migraine is a debilitating chronic pain condition afflicting 12% of American adults. Current conventional treatments rely on medications that provide limited or transient relief, target symptoms rather than the underlying causes of pain, and are associated with significant side effects and costs. It is therefore essential to investigate non-pharmacologic approaches to conventional headache treatments. Certain fatty acids and their bioactive metabolites regulate multiple pain-related biochemical pathways. Controlled clinical trials investigating pain modulation in response to dietary changes while exploring relevant mechanisms of action in humans are lacking.
In a recent feasibility study in patients with chronic daily headache (CDH), we found that targeted fatty acid modifications altered circulating endovanilloids, while reducing headache frequency and improving quality of life. These findings support our proposed model in which diet-induced alterations in endovanilloids modulate transient receptor potential cation channel subfamily V member 1 (TRPV1) activity in vivo, leading to important implications for migraine and chronic pain in general.
The goal of this research is to assess whether dietary PUFA modifications can result in predicted changes in circulating endovanilloids and improvement in headache-related clinical outcomes. The proposed 3-arm, 26-week,randomized, controlled, single-blind trial, with 51 subjects in each group, includes a 4-week baseline of usual care, followed by randomization to one of three 22-week dietary interventions plus usual care. Each of the three arms involves specific modifications of dietary fatty acid intakes through a whole foods diet. Participants in the dietary interventions receive food sufficient for 2 meals and 2 snacks daily along with extensive dietary counseling.
Specific aims are:
This proposal utilizes an innovative design and hypotheses to address current research funding priorities, by examining clinical efficacy and underlying mechanisms of a promising dietary manipulation with the distinct potential for high impact in terms of ameliorating a chronic, disabling pain disorder.
