The head of Hadassah Ein Kerem Hospital's team treating Prime Minister Ariel Sharon, Professor Felix Umansky, said Monday that in spite of the positive signs Sharon had shown on Monday, it would take several days to determine his cognitive functioning. Umansky said that his team was looking for Sharon to show more significant responses to pain, to open his eyes and to more appreciably move his leg and hand. Sharon's began breathing independently on Monday morning, after the coma-inducing drugs affecting Sharon began to wear off. Umansky said that his breathing improved as the day progressed, and that it was still unclear if Sharon was conscious. It was still to early to tell if Sharon had incurred any damage to the right lobe of his brain, Umansky concluded.
