The latest statement on the health of Israeli Prime Minister Ariel Sharonhas been given to the press this morning. Sharon’s condition remains stable, if critical, in Hadassah hospital in Jerusalem.Hospital director Shlomo Mor-Yosef says Sharon’s condition has not changed overnight, and that all his key vital signs are stable, which gives grounds for optimism. However his colleagues admit the risks of brain damage from the massive internal bleeding he suffered on Thursday are high, and he may never emerge from his medically-induced coma. Sharon was hit by a minor stroke in December. He bounced straight back into full-time politics on blood-thinning medication to prevent blood clots reaching the brain, but this raised the risk of the more serious bleeding stroke that he suffered on Wednesday night. Sharon had been due to visit hospital this week anyway, for minor surgery on a hole in the heart. At 77 and severely overweight, doctors already considered Sharon as a high-risk patient before this attack.
