A British teenager has been diagnosed with a rare brain disorder, whereby she loses her memory every 24 hours.
Jess Lydon, from Coventry, England, is affected by the rare Susac's Syndrome, which wipes her slate of memories clean every day.
That basically means she wakes up every morning with no memory of what happened the day before, the Mail Online reported.
"I can hardly remember anything that has happened in the last year - not even Christmas or my last birthday in December," the Mail Online quoted Jess as saying.
"When I look at photographs I just find it confusing. The really upsetting thing is I don't remember my nan's funeral last year," she added.
There have been only 250 cases of Susac's Syndrome. Incidentally, this disorder is also referred to as "Groundhog's Day", so named after the 1993 American comedy film of the same name. In the film, Bill Murray relives the same day again and again.
Perhaps one of the worst fallouts of the syndrome is the fact that Jesse doesn't remember breaking-up with her boyfriend of two years. In an ironic twist of fate, this particular predicament of hers is mirrored in another Hollywood film, "50 First Dates", starring Adam Sandler and Drew Barrymore.
Jesse stays with her mother Tracey, who helps her with her daily tasks. She said it was not fair that Jesse had been struck down by such a rare syndrome.
"We don't know how long this is going to affect her or what the future is going to hold for her," she added.
What is Susac Syndrome?
Susac Syndrome is a rare brain disorder characterized by poor blood supply to retinal and brain tissue. It is named after Dr. John Susac, of Winter Haven in Florida, who first described the condition in 1979.
Unfortunately, the condition mostly affects women, especially younger girls.
The causes are unknown and there are no proper symptoms to diagnose the condition. It could take up to five years for the condition to correct itself.
