More than a quarter of teens say they have experienced a migraine headache. And veterans, who served in the Middle East, report two to four times the incidence of migraines as the general public. Now there is a device that uses technology to help prevent – and treat – debilitating headaches. Courtney Clarke is passionate about all the things a high school senior would like, hanging out with friends, music, making jewelry, and playing sports, but often those had to take a backseat to something else in her life. “I've missed so many classes. I've missed sports practices, games, birthday parties. There's this one surprise party that I spent a while planning for one of my friends, and I couldn't even go. It was pretty sad,” said Clarke, 18 of New York City. At the age of seven, she started suffering from migraines. Over-the-counter pain meds stopped working. Insurance doesn't always cover prescription pills for young people, plus they cause side effects.
