Moore 'Hyper' and on Adderall Before 911 Call?

Since Demi Moore's shocking hospitalization on Monday night for "exhaustion", troubling new reports are surfacing that shed light on what may have led to the actress' trip to the hospital after 911 was called to her home near Benedict Canyon.

According to E! News, the 49-year-old was "acting crazy" and "pretty hyper" that night at a birthday dinner party she hosted for her friend, Hollywood socialite Heather Perry. Later that night, Moore reportedly began to convulse "like she was having a seizure," prompting a guest that had stayed behind to dial 911.

Demi Moore To Be Treated for 'Exhaustion'

According to TMZ, the actress had inhaled a dangerous amount of nitrous oxide, also known as "whip-its."

Radar is reporting that Moore will now be seeking treatment for anorexia and substance abuse addictions -- Adderall being her prescription drug of choice, according to the news outlet.

"The pills and starvation destroyed Demi and this has been a problem for about a year," a source tells Radar. "She's constantly jacked up on Adderall and combining that with not eating accounts for her loopy behavior and anorexic body frame. She literally refuses to eat any food."

The actress' rep tells ET only that, "Because of the stresses in her life right now, Demi has chosen to seek professional assistance to treat her exhaustion and improve her overall health. She looks forward to getting well and is grateful for the support of her family and friends."

The past couple of months have been a trying time for Moore, splitting from husband Ashton Kutcher last November after rampant rumors of Kutcher's extramarital affairs. Tabloids have also scrutinized her apparent recent rapid weight loss.

"She's depressed over her career and coupled with the stress and heartbreak over the split, all of this emotional turmoil in totality has taken a serious physical toll on her body," a source tells Radar.

Moore does however, seem to have a loyal friend in Madonna.

Madonna reached out to Moore shortly after news broke of her hospitalization, E! News reports.

"Madonna told Demi she was there if she needs anything," a source tells E!. "They're pretty tight."

Moore's ex, Ashton Kutcher, has been seen partying in Brazil recently but he seems to still have sympathy for her.

"Ashton is deeply concerned for Demi," a source reportedly told People. "He still cares about her and wants the best for her. But their marriage is ending and they are both moving on with their lives."

By the time the actor heard of Moore's hospitalization he was already in Brazil for an ad campaign that he's working on.
