Handedness, eyedness, and crossed hand-eye dominance in male and female patients with migraine with and without aura: a pilot study.
The possible relationships of migraine to left-handedness and left-eyedness, as well as sex and aura-related differences, were examined. 146 migraine patients (M age=32.1 yr., SD=9.5) and 141 controls (M age=30.0 yr., SD=9.3) participated. Hand preference was assessed by the modified version of the Edinburgh Handedness Inventory. Ocular dominance was measured by means of the near-far alignment test. Migraine diagnoses were made on the basis of criteria provided from the International Headache Society. In the overall sample and in women, left-handedness and left-eyedness were not significantly correlated with migraine. In men, the incidence of left-handedness and left-eyedness were significantly higher in patients than in controls. The presence of aura in patients with migraine was significantly associated with the incidence of left-eyedness and crossed hand-eye dominance, but not handedness, for the total sample and women. These results suggest that there may be a tendency towards anomalous dominance, especially left-eyedness, in migraine patients particularly those with aura.
