Migraine and Weather Factors
April 27, 2011 | Author Dr Robbins

Weather is often a trigger for many migraines sufferers. Neurologists at the Medical University of Vienna, Austria examined the impact of weather change on the risk of occurrence and persistence of headache and migraine.The correlation of subjective weather perception with objective weather data was also examined. 446 study participants were screened with 397 chosen based on proximity to the Central Institute of Meteorology and Geodynamics in Vienna. Of these, 327 patients kept diaries detailing their headaches and response to weather.

Although the analysis revealed different trigger scenarios, none of these findings remained statistically significant after multiple testing, revealing that weather perceptions were subjective and did not correlate with the occurrence or persistence of migraine or headache.

This study revealed it is important to study the relationship between migraine and weather patterns independently of patients’ subjective perception. Other factors such as menstruation or lifestyle trigger headache or migraine more frequently, and that these factors should be main targets of therapeutic approach.

Pen,

If I understand correctly, this particular study did not show a correlation between weather changes and migraine.

Take it with a grain of salt as is a good idea with all studies. For one thing, the sample size is fairly small. For another, the sample is not random. Participants were selected for their geographic proximity to Central Institute of Meteorology and Geodynamics in Vienna.

Whether or not that bias was accounted for in the study was not stated.

I am not saying the study is not valid. What I am saying as I do with any study is question, question, question.

Yes, I think the problem also is the wide variety of what constitutes trigger across people. So even if it is a trigger for 20% or 30%, the effect would get wiped out by the other people in the study for whom it is not a trigger. They should only test this for the subset of the population who claim it is a trigger

Might I suggest a response to Larry Robbins on his blog?

I am sure he would welcome comments. There is a box for them.
Maybe just cut and paste what you put here...

I have no problems with rainy weather. I can have headaches on a nice or rainy day, no connection. Now heat affects me if it's indoors or out and it seems worse if it's inside (as you can see in "my stupid office." lol!

) Everyone always thinks I will have a migraine on a rainy day and I might, but not always, and not any more than a nice day.

I work with someone who is gets headaches more on rainy days but he also has severe sinus problems. I have never had a sinus infection in my life. So maybe the sinus problems trigger the migraine reaction or something.
