For migraine sufferers, the sudden debilitating onset can be excruciating yet unexplained. However researchers have discovered a genetic link that might begin to explain why.

Of the 15 percent of U.S. children who suffer from migraines, about one-third of all children, have migraines with aura - which involve a set of symptoms such as flashes of light, blind spots, and tingling. New research shows these migraines in children may be related to a certain heart defect.

Girls who suffer with migraines are more likely than their peers to gain extra weight during adulthood, according to new research.
