Israel’s comatose Sharon shows brain activity

Question of the Day

Is it still considered bad form to talk politics during a social gathering?

JERUSALEM (AP) — Seven years after a massive stroke removed him from office and left him in a vegetative state, former Israeli Prime Minister Ariel Sharon is able to process information and has exhibited “robust activity” in his brain, according to doctors who conducted recent tests.

Though some hoped Mr. Sharon might regain consciousness and resume his life, experts warned that was highly unlikely.

The medical team that tested him last week said Monday that the scans showed the 84-year-old Mr. Sharon responding to pictures of his family and recordings of his son’s voice. They cautioned, however, it is not clear how much he understood, stressing the chances of his regaining full capacities are almost zero.

“We were surprised to see such robust activity in his brain,” said Dr. Alon Friedman, head of the Zlotowski Center for Neuroscience at Ben-Gurion University in Beersheba. “The information is getting in and is getting processed. He hears what they are saying. To what extent he understands, we cannot say for sure … but there are encouraging hints that he does.”

Mr. Sharon was at the height of his political power in early 2006 when a devastating stroke incapacitated him. He has been in a deep coma ever since, connected to a respirator. His family has said he sometimes opens his eyes and moves his fingers, but little else has been disclosed about his condition. No one has suggested that his cognitive functions have returned.

Last week a team of Israeli and U.S. scientists performed a series of tests on him at Soroka Hospital in Beersheba, using a newly developed functional MRI to assess his brain function. Dr. Friedman said the two-hour procedure was among the first of its type to be conducted on someone who had suffered such a brain hemorrhage. It is also rare to perform such tests on someone Mr. Sharon’s age, he said.

Dr. Friedman would not disclose additional information about Mr. Sharon’s medical state or say whether there had been any physical reactions to the stimuli. He said the findings would provide solace to Mr. Sharon’s sons, Gilad and Omri, giving them confirmation that their father could hear them. Omri Sharon declined comment when contacted by The Associated Press on Monday.

Raanan Gissin, a longtime Sharon confidante, said those close to the former leader were encouraged by the tests.

“The hope is not that he will return to be the leader that he was, but basically the hope … that Sharon will return to normal life,” he said. “The people of Israel really feel gratitude toward Sharon, and they think he deserves to end his life like a normal person.”

Experts doubted that would happen.

Dr. Ilan Shelef, head of medical imaging at Soroka University Medical Center, sought to temper expectations from the results of Thursday’s scans.

“What is very important to understand is that we have a snapshot of what happened” during the test, said Dr. Shelef, who participated in the testing. “He received some stimuli from his family, and he responded to these stimuli. It was a metabolic response in the brain,” he said. “Metabolic” refers to physical reactions.

“We don’t know what happened two years ago or four years ago, and we have no idea what will happen in the future,” he said. “We just know that on Thursday evening there was a metabolic response in the brain of former Prime Minister Ariel Sharon.”

Dr. Nicholas Schiff, professor of neuroscience at Weill Cornell Medical College, called the findings “interesting but ambiguous” and warned against reading too much into the tests.

Dr. Schiff, who did not participate in the testing and said he had not reviewed the research, said the FMRI is a widely used tool used for gathering data, but there is no consensus among researchers on interpreting the results. “In general, there are very few uses of FMRIs that unequivocally demonstrate awareness in patients that appear unresponsive,” he said.
