Debilitating migraine headaches, which afflict up to 15 percent of the world's population, are thought to be
sparked by nerve cells called trigeminal ganglion neurons.
Dr. Siqueira said she and her colleagues are now investigating whether the problem was the result of an auto - immune disorder
sparked by one of the viruses that caused the immune system to attack
nerve cells, similar to what occurs in Zika patients who develop Guillain - Barré Syndrome.
