While the world waits for news about whether the Olsen twins will be joining the "Full House" reboot set to appear on Netflix, concerns are different at the Olsen household, as it has been reported that Ashley Olsen's 2015 sees her battling a serious health condition.

For a few weeks, the Olsen twins have been making news as fans wonder whether they'll be appearing in the John Stamos-produced Netflix "Fuller House," as they had apparently not even heard the project was going on; however, things are much more complex for Ashley Olsen's 2015, and she might be downright unable to shoot scenes if she were to have a cameo.

According to RTE.ie, a source close to the famous twins has stated that Ashley Olsen's 2015 has grown darker in the past few months, as she was diagnosed with Lyme disease, an incurable illness that can attack the nervous system.

Lyme disease (or Lyme borreliosis) is an infection illness caused by a particular bacteria that comes from being bitten by a tick, and its symptoms can vary from rashes to fevers, headaches, exhaustion and even loss of the ability to move either side of the face (or in its entirety), pain in the joints or even heart palpitations; and this is what Ashley Olsen's 2015 sees the retired actress facing.

The actress also suffers from attention deficit disorder, and has been taking Ritalin to treat this condition ever since she was a child.

The New Zealand Herald reports that a source close to Mary-Kate's twin has come out to speak about the hardships in Ashley Olsen's 2015, as the twins' younger sister Elizabeth Olsen hits mainstream success becoming one of the latest entries of the "Avengers" films.

The Irish Independent reports that the actress and fashion designer's condition has gotten worse since 2012, which has prompted her from mostly disappearing from the spotlight.

There has been no official confirmation of Ashley Olsen's 2015 condition.
