I’m left-handed so I thought this information was pretty interesting. Earlier study findings had shown that there was possibly a link between migraines and being left-handed. Research from more than 2 decades ago reported finding that more people who are left-handed suffered from migraines. But Dr. Katrin Biehl and colleagues, at the University of Munster, report in the medical journal Cephalalgia that they found no significant difference in the frequency or grade of left-handedness between people who have migraines and those who do not.
For this study, the combined analysis included a total of 980 migraine patients and 1738 control subjects. Overall, 7.3 percent of the migraine group and 6.8 percent of the control subjects were left-handed.
The investigators conclude there is not a significant association between migraine and being left-handed.
