Study explains why light worsens migraine headaches.
BOSTON – Ask anyone who suffers from migraine headaches what they do when they’re having an attack, and you’re likely to hear “go into a dark room.” And although it’s long been known that light makes migraines worse, the reason why has been unclear.
Now scientists at Beth Israel Deaconess Medical Center (BIDMC) have identified a new visual pathway that underlies sensitivity to light during migraine in both blind individuals and in individuals with normal eyesight. The findings, which appear today in the Advance On-line issue of Nature Neuroscience, help explain the mechanism behind this widespread condition.
