Feb. 28, 2011 -- Charlie Sheen's recent words and his sometimes inexplicable speech have some medical experts wondering about his mental health.
During an interview with ABC News, the controversial actor said he would sue CBS and Warner Bros. for "tons" after the cancellation of the rest of thhe season of his hit show "Two and a Half Men."
"I'm gonna actually put it on a scale and be like 'Little more, little more,'" he said. "'Add some gold. All your toupees.' I'm a high priest. Vatican assassin warlock. ... Come on, man."
CBS' move came after the actor launched into a scathing rant against show creator Chuck Lorre on a radio program.
The network announced Thursday night that it had canceled the rest of the show's season as a result of Sheen's "statements, conduct and condition."
Sheen said he did not know where his words came from.
"It comes from my grand wizard master. I don't know. Stuff just comes out and it's entertaining and it's fun," he said.
J. Raymond DePaulo, a psychiatrist at Johns Hopkins, said changes in mood and speech can be clues to a manic state of mind.
"In terms of self-attitude, patients can be very grandiose, either in the form of being just supremely self-confident," DePaulo said. "Patients with moderate or even milder forms of mania or hypomania can tell me that they feel invincible."
'I Got Tiger Blood, Man'
"I'm different," Sheen said during the interview. "I just have a different constitution. I have a different brain. I got tiger blood, man."
Experts say that many of his complaints during that sitdown -- from sleeplessness to what Sheen called a highly evolved brain that can't be unplugged -- are textbook symptoms of being bipolar, a disorder that frequently leads to substance abuse.
"It's no joke," addiction expert Drew Pinsky told TMZ. "He's getting manic. These are bipolar, manic symptoms."
Though doctors said it was impossible to diagnose Sheen without examining him, they agreed that signs of mania should be taken seriously.
