SUMMARY:&quot\;Visual processing differences in migraine\, between attacks
 \, and their links with environmental visual triggers. From the retina to

DESCRIPTION:Many researchers have assessed visual processing in migraine d
 ue to the intense sensitivity to light that patients experience (photophob
 ia)\, the visual disturbances that may precede an attack (visual aura)\, a
 nd the fact that visual stimuli can trigger attacks in up to 60% of patien
 ts (typically\, stripes and flicker). Visual tests can be used as non-inva
 sive tools to test models of the pathophysiology underlying various neurol
 ogical conditions\, including migraine. The nature of the tasks used previ
 ously in migraine research indicate distributed processing differences\, b
 etween attacks\, throughout the visual pathways from the retina to the pri
 mary visual cortex and extrastriate cortical areas. In this talk\, I will 
 review the literature in this area and end with comments about its usefuln
 ess informing the design of the environment in which we live and enabling 
 patients to predict impending attacks.
