Migraine Triggers

Studies presented at #AHS18SF explore the link between 4 commonly believed migraine triggers and the onset of a migraine attack

Patients living with migraine are prone to triggers that raise the risk for the onset of an attack—whether it be diet, stress, weather or non-working days. Migraine triggers vary for each patient, not everyone has a clear trigger for an attack, and not every attack has a clear trigger. At the American Headache Society’s 60th Annual Scientific Meeting in San Francisco, leading headache specialists and migraine experts presented five clinical studies that explored the connection between widely suspected, or commonly believed, migraine triggers and the onset of a migraine attack.

1. Caffeine

In order to better understand the effects of caffeine on the onset of a migraine attack, researchers used a web-based digital platform study to assess the relationship between caffeine intake and migraine in individuals over a period of 90 days. In reviewing the participants’ answers about migraine triggers, researchers concluded that while caffeine is widely suspected to be a migraine trigger, caffeine may, in fact, reduce the risk of a migraine in one out of 13 people. Overall, caffeine did not increase the risk of migraine attack for any individual participating in the study.

2. Chocolate

In a double-blind study conducted over a 90-day period, researchers looked at how many participants believed chocolate to be a trigger for their migraine attacks, and tried to determine a link between consuming chocolate and the onset of a migraine attack. The researchers found that although chocolate is widely believed to trigger migraine attacks, there was little to no statistical association between the two.

3. Non-Working Days

Previous studies have been unable to provide evidence that weekend headache—a term used to describe the onset of a migraine attack on non-working days—can be a significant trigger for migraine. Researchers came to the same conclusion through utilization of Curelator Headache®, comparing the occurrence of migraine attacks on work days versus non-working days in the self-reported user data over a 90-day period.

4. Weather

In this retrospective study, researchers observed over a 60-day period that specific combinations of weather variables are predictive of days with high risk of the migraine attack onset for individuals with episodic migraine. Barometric pressure had the most notable effect on migraine attack onset; however, dry bulb temperature, relative humidity and wind speed also had a significant impact on patients.
