Michael Jackson spent 60 days without sleep 'Real', says expert

Michael Jackson deep difficulty sleeping has taken protagonism in the controversy surrounding his death, with testimony from experts in his wrongful death trial suggesting the pop singer was 60 days without sleep 'real'.

Jackson would have been called propofol, the powerful anesthetic that finally caused his 2009 death, his "milk". Charles Czeisler, M.D., Ph.d., Division of medicine, sleep at Harvard Medical School, testified in the trial against the concert promoter AEG Live that drug interruptions normal sleep cycles and starves the body of rapid eye movement, or REM, sleep, while a person to feel as if he or she has had a true night dream of, reports CNN.

"It would be like eating some sort of pellet of cellulose instead of dinner", Czeisler said in his testimony, according to CNN. "Your stomach would be full and you would not be hungry, but would be zero calories and failure to comply with any of your nutrition needs."

Throughout the night, the body cycles through four stages of sleep: three stages of non-REM and REM stage (for more information about what happens in each stage, click here). Each complete cycle takes about 90 minutes, usually end up in REM sleep, Phillip Gehrman, Ph.d., clinical director of the medicine program of sleep behavior at the University of Pennsylvania, says The Huffington Post. First the REM cycle is fairly short, about 10 minutes, and cycles get more long throughout the night, until an hour or so, according to WebMD.

During REM sleep, the brain activity is very similar to the Vigil, explains Gehrman, earning the nickname of "paradoxical sleep." "His eyes move quickly around as if you are scanning your environment," he says. This is also the portion of dream the dream, and the muscles of the body are temporarily paralyzed to prevent Act those dreams. (That explains why when awakened from REM sleep, people sometimes experience a condition called sleep paralysis. Another condition of sleep, disorder of REM behavior, it can occur when the paralysis does not pass correctly and someone act out their dreams.)

While scientists do not fully understand the function of REM sleep in health in general, you are widely believed to play an important role in the consolidation of memory and perhaps also in the processing of emotions, Gehrman says.

Propofol, the anesthetic took Jackson, it is a powerful position of REM sleep, says W. Christopher Winter, M.D., director doctor of the center of medicine in the Martha Jefferson Hospital sleep in Virginia, which does not evaluate Jackson.

"Propofol induces unconsciousness."There is a difference between being unconscious and being asleep, says HuffPost. "Sleep is a process of the range: REM sleep, deep sleep, releasing hormone." "These things can not be happening when you're only unconscious."

REM sleep deprivation grave probably may affect State of mood, concentration, focus, tolerance of pain and memory, winter says. According to CNN, Czeisler testified that lab rats die after spending five weeks without REM sleep:

Depriving someone of REM sleep for a long period of time is full of anxiety, paranoid, depressed, unable to learn, distracted and neglected, said Czeisler. They lose their balance and your appetite, while their physical reflexes get 10 times slower and their emotional responses 10 times stronger, he said.

But the winter adds a note of caution: when Jackson propofol, sleep REM it would have been deleted by night, but probably do not know whether he was to catch sleep during the day, nodding perhaps inadvertently. When the brain is severely deprived of REM sleep, enter that stage much faster, a phenomenon called REM pressure, winter, he says.

Gehrman and winter said Jackson case is unique; the typical patient does not have to worry about REM sleep deprivation. If you think that you are not dreaming, it could just be that you do not remember your dreams, not that not having them, explains Gehrman.

"Deprivation REM is very difficult and is not something that the average individual, even someone who has actually major problems with his dream, really need to worry," says winter.
