LOS ANGELES -- An expert told a jury that Michael Jackson exhibited symptoms of someone who was totally sleep-deprived when he died.
Dr. Charles Czeisler said the singer's weight loss, and difficulty remembering dance moves and lyrics were all consistent with someone who hadn't got any real sleep in a long time.
The Harvard professor is testifying as a sleep expert in a lawsuit filed by the singer's mother against concert promoter AEG Live LLC.
The sleep deprivation was likely caused by Jackson's use of the anesthetic propofol, which Czeisler says would put the singer in a drug-induced coma and not meet his body's need for actual sleep.
