Teen's mysterious condition sees her lose memory every two hours

A mysterious condition that causes a teenager’s memory to reset every two hours has doctors baffled.

Teenager Riley Horner, from Illinois, was accidentally kicked in the head by a student crowdsurfing at a school dance on June 11.

“I’m very confused and I try to think back, and I can’t,” she told US TV news outlet WQAD.

Since then, the Illinois teen wakes up everyday thinking it is June 11, she has had multiple seizures and her memory resets every two hours.

“I'm not making memories.” Riley said.

“And I'm just really scared.”

According to WQAD News, Riley’s doctors say her case is a “medical mystery” as they cannot find anything physically wrong with her through CT scans or MRIs.

“They told us that she may just be like this forever and I am not okay with that,” Riley's mum Sarah told the US’s ABC News.

According to Sarah, research suggests six months of short-term memory can cause irreversible damage.

“We need help,” the mum said.

“We need somebody that knows a little bit more because she deserves better.

“I mean she wanted to be in the medical field and now she can’t even hold a job if she wanted to.”

Sarah explained her brother had recently passed away.

Riley’s family have to break the news of her uncle’s death to the teenager every day.

Before June 11, Riley was an athlete and a bright student.

Now she struggles to find her locker and has to take extensive notes in class – setting alarms ever few hours to remind her to revise her notes.

“I know it’s hard for them, as much as it’s hard from me and people just don’t understand – it’s like a movie,” Riley said.
