A quarter century ago, researchers suggested that people who are left-handed were more likely to have migraine than right-handed people. A new, larger study has determined that lefties are not more prone to migraine.

German researchers assessed “handedness” in 100 migraineurs and 100 control subjects. They also looked at data from five other similar studies, for a total of 980 migraineurs and 1738 non-migraineurs. The results: 7.3% of migraineurs and 6.8% of control subjects were left-handed. The researchers concluded that there was no significant difference in the frequency of left-handedness between people who have migraine and those who don’t.
