Bridget Araldi’s headaches started after a concussion on the soccer field, and they became so debilitating that the Wilton girl missed 70 days of her sophomore year at high school. She spent much of that time lying in her darkened bedroom, her head covered with cold cloths. A succession of doctors Araldi’s mother took her to did not offer any relief—an experience that is not unusual, according to a new study. The study shows that most children do not get proper treatment for migraines. Many doctors who specialize in headaches say this is because children’s pain is too often dismissed.
