Why light makes migraines worse

By Kelley Luckstein

Crossed wires can be a real headache, especially for people with migraines, a new study shows. The crisscrossing of nerve fibers in a part of the brain called the thalamus results in increased migraine pain after people are exposed to light, researchers report online January 10 in Nature Neuroscience…


“There have been no theories as to why light in general makes headache pain worse,” says David Dodick, a neurologist at the Mayo Clinic in Scottsdale, Ariz. “That’s what makes this so groundbreaking. It solves a mystery that has been around for many, many, many decades.”
