The Norwegian National Headache Center found that people with high blood pressure were less likely to have migraine headaches. Previously, it was believed that high blood pressure was a causative factor for migraine headaches, but research shows otherwise.

The study followed more than 50,000 adults and included information on headache frequency, use of blood pressure medication, and blood pressure readings. People with the highest pulse pressure had up to 50% fewer headaches.

Knowing that high blood pressure doesn't cause migraines is a good thing -- it leads researchers closer to better understanding painful migraine headaches. Also, blood pressure medication is sometimes prescribed for migraines and this study may prove that is unnecessary or ineffective. However, it's clearly not a reason to stop treating high blood pressure. As my grandmother used to say, "don't trade one evil for another." High blood pressure is a dangerous condition that increases your risk of heart disease, stroke, kidney failure, and can even lead to reduced function later in life.
