Migraine and left-handedness: is there a connection?
In 1982, Geschwind and Behan reported an association between migraine headache and left-handedness. The present study was an attempt to test this hypothesis by comparing the frequency of left-handedness in migraine and tension headache patients at a headache center. Cluster headache cases were also included because Geschwind and Behan suspected that the association might be even stronger in this disorder. A special scoring method for handedness was devised by Geschwind and Behan to help identify a possible higher risk in mixed-handedness subjects. No significant associations emerged in any of these tests. A modest association of cluster headache and left-handedness disappeared when adjustment was made for the strong predilection of cluster headache for the male sex.
