A North Carolina high school student’s life drastically changed after a sporting accident in 2017. It left her with a rare condition that causes her brain to “reset” when she goes to bed and wake up without any memories from the day before.

Caitlin Little, who was part of Southeast Guilford High School’s cross country program, suffered a concussion on Oct. 12, 2017, after someone stumbled and hit her in the head. She was diagnosed with anterograde amnesia—which is the loss of the ability to create new memories after an incident that caused amnesia.
