As Charlie Sheen’s media blitz following the cancellation of his sitcom continues, experts worry the actor is showing signs of bipolar disorder, according to Popeater.

 

"He looks bipolar. He's in a particularly manic phase," psychologist Stuart Fischoff tells the website. "His reality testing has been severely impaired, marked by delusions of grandeur. His head now is as large as the moon."

 

Sheen certainly thinks highly of himself, as he proved in an interview with ABC’s 20/20. "You borrow my brain for five seconds and just be like, 'Dude, can't handle it! Unplug this bastard!'" Sheen said. "It fires in a way that is perhaps not from this terrestrial realm."
