Hopes were raised on Thursday after Shimon Peres spent a second night in hospital without further complications following a stroke.
Dr Ze’ev Feldman, one of the doctors treating the former Israeli president at the Sheba Medical Centre in Ramat Gan, said there was a chance he could make a better recovery that initially expected.
According to Israeli site Ynetnews, Dr Feldman said: “The fact that he returned to consciousness is extremely significant and may enable a recovery in the future and a return to fuller functionality, as opposed to a person who remains unconscious and cannot communicate.”
However, the doctor warned: “His situation is still serious but stable and the danger still exists considering his situation and age.”
