Kelly Brock

For the first four years of her life, Savannah Brock didn't sleep more than a few hours at a time. Though desperately tired, the child couldn't fall or stay asleep due to an unrelenting urge to move her legs. While Savannah's parents knew something was wrong, medical tests didn't reveal the cause. Then they met a Mayo Clinic pediatric sleep specialist who listened to the family's story and pinpointed the problem.
