1044 women with migraine: the effect of environmental stimuli.
This study initiated by a self-help migraine group investigated disability caused by visual environmental stimuli, e.g. glare, flicker, pattern and color. One thousand forty-four women with migraine completed the self-report questionnaire on visual environmental stimuli reported in earlier studies to precipitate or aggravate migraine. One hundred twenty-one female controls were obtained from general practice and hospital out-patients. The responses of the classical, common and non-migraine groups were compared. Women with classical migraine expressed greater disability than those with common migraine or controls both in respect of number of visual sensitivities reported (P < 0.0001) and severity of consequences of such stimuli (P < 0.0001). This study indicated differences between classical and common migraine outside of the attack phase apart from aura. Reported range of sensitivities for the migraineurs peaked between the ages of 46-60 years. A high level of unrealized disability caused by visual environmental stimuli was thus identified in hitherto unexplored self-help groups.
