Doctors at the Hadassah Ein Karem Hospital in Jerusalem said that Sharon is not showing signs of regaining consciousness although they have been trying to get him out of his induced coma since Monday.

Israeli online daily Haaretz reported that the doctors have been gradually lessening the dosage of the sedatives he has been receiving in the wake of the massive stroke and cerebral hemorrhage he underwent last week.
The condition of Sharon remains unchanged; serious but stable, they said, he will continue to be hooked up to a respirator, while also breathing on his own, and his life continues to be in danger.
Haaretz added that a prominent Harvard neurologist on Thursday joined the chorus that has been questioning Sharon’s treatment ever he suffered from Cerebral Amyloid Angiopathy (CAA), a disease affecting the blood vessels of the brain.
Also, Dr. Steven Greenberg, Associate Professor of Neurology at Harvard Medical School in Boston, said that CAA constitutes a "central risk factor" for the development of a cerebral hemorrhage.
He added said that blood thinning medicines of the kind that Sharon received could cause a small hemorrhage to turn into a large one and a catastrophic stroke.
Greenberg said that he based his comments on very particular information released by Sharon’s doctors.
On Thursday, doctors conducted a brain scan on Sharon and found out that the remnants of the blood in his brain from last week’s massive stroke have been absorbed.
In light of these results, doctors removed a tube that they had inserted into Sharon’s skull to relieve pressure on his brain, a statement from Hadassah Hospital said.
The heart activity is regular; he suffered disorders in his heart beat rate, but it was treated immediately and did not cause a dramatic damage in his condition.
