Rosacea is linked to migraines in women

Written by on November 10, 2016 in blushing, flushing, What Causes Rosacea? with 2 Comments

A just published paper has found a statistical link between rosacea and migraines. Specifically, the research has found that female rosacea sufferers over the age of 50 had a `significantly higher prevalence and risk of incident migraine’. So what might we learn about treating both rosacea and migraines from this research? The takeaways from this research are summarised below.

Research from statistics

This sort of research seeks to take information already collected from a large population to make discoveries about possible links between conditions. Any links discovered might direct futher research into the significance of for example, co-existing conditions. Benefits of this sort of research might arise when a new understanding of how a disease progresses, or can be now treated are considered in the light of new information from the co-existing condition.

Other research based on statistical analysis of population data has recently suggested links between rosacea and conditions such as dementia, auto-immune diseases, or indeed Parkinson’s disease.

Abstract

Prevalence and risk of migraine in patients with rosacea: A population-based cohort study

Egeberg A, Ashina M, Gaist D, Gislason GH, Thyssen JP, J Am Acad Dermatol. 2016 Nov 3.

Background: Rosacea features increased neurovascular reactivity; migraine is a complex neurologic disorder characterized by recurrent episodes of headache associated with nausea and increased sensitivity to light and sound.

Objective: We evaluated the prevalence and risk of new-onset migraine in patients with rosacea.

Methods: All Danish individuals 18 years of age or older were linked in nationwide registers. Adjusted hazard ratios (HRs) were estimated by Cox regression.

Results: In the total cohort (n = 4,361,688), there were 49,475 patients with rosacea. Baseline prevalence of migraine was 7.3% and 12.1% in the reference population and in patients with rosacea, respectively.

The fully adjusted HR of migraine was 1.31 (95% confidence interval 1.23-1.39) for patients with rosacea.

Patients with phymatous rosacea (n = 594) had no increased risk of migraine (adjusted HR 0.45; 95% confidence interval 0.11-1.80), whereas patients with ocular rosacea (n = 6977) had a 69% increased risk (adjusted HR 1.69; 95% confidence interval 1.43-1.99).

Notably, the risk was higher among patients age 50 years or older than in younger individuals, and the risk was only significant among women.

Limitations: We were unable to distinguish between migraine subtypes.

Conclusion: We found a significantly higher prevalence and risk of incident migraine especially in female patients with rosacea. These data add to the accumulating evidence for a link between rosacea and the central nervous system.

So What is happening?

Although these sorts of papers do good research and find results worth publishing sometimes we are left wondering what is it all about?

The basis for the co-occurrence of migraine and rosacea is unknown; however, vascular abnormality is central to the etiopathogenesis of both disorders.

Patients with erythematotelangiectatic rosacea often report episodes with prolonged flushing of affected facial skin, and studies have shown increased tissue expression of vascular endothelial growth factor and vasoactive intestinal growth factor receptors in patients with rosacea.

Are there any possible clues relating to the link?

Flushing and disease exacerbation in rosacea is often caused by particular triggers such as stress, exposure to sunlight, hot or cold temperature, strenuous exercise, spicy foods, and hot drinks.

Several triggers for migraine share an overlap with rosacea triggers including stress and alcohol.

Future studies in patients with both rosacea and migraine are required to establish whether these triggers co-occur in the same individual.

However, we emphasize that the pathogenic link between rosacea and migraine remains unclear, and additional studies are needed to elucidate the underlying cause for the observed association.

It is worth also remembering that these sorts of statistical studies have specific limitations.

Observational studies cannot determine causality.

Final Conclusion

OK so you have reached the bottom of this article, what should you take away from this paper ? Glad you asked 🙂

With the above caveats in mind, we conclude that we found a significantly higher prevalence and risk of new-onset migraine in female patients with rosacea, compared with the general population.

The risk was highest among older individuals, and in particular among individuals with ocular rosacea. These data add to the accumulating evidence for a link between rosacea and the central nervous system.

    I am female almost 50 and have both migraine and rosacea. Migraine came first then rosacea about 3 years ago. I keep off caffeine but when I get a migraine I have caffeine to help reduce migraine. However this makes rosacea worse as then having coffee. I think avoiding chocolate may help with the rosacea and possibly the migraine. It’s a balancing act!

    I’ve finally been diagnosed . Ocular rosacea and also face, neck, and ears. The Meds and creams are not working. Now with migraines and in darkroom for many days. I was fed up with migraines and now prescribed a med .one pill is $7.50 a day and I can take 2. I certainly cannot afford all these antibiotics , creams, gels and now migraine pills with no insurance. I moved from a warmer area which never goes above 20 Celsius or below -12. Now I live in an area plus 45 Celsius to -56 Celsius for past 3 years and feel this is the cause of my nightmare
