Doctors treating injured Formula 1 legend Michael Schumacher are reducing his sedation to prepare to bring him out of a coma, his manager says.
This step will allow the “waking up process” to start, Sabine Kehm said in a statement.
But bringing the seven-times champion out of the coma “could take a long time”, she added.
Schumacher suffered a severe head injury in a skiing accident in the French Alps on 29 December.
He was put into a medically induced coma by his doctors at a clinic in Grenoble following operations to remove blood clots from his brain.
Doctors have kept the 45-year-old German asleep to help reduce the swelling.
Ms Kehm was approached by the media for comment on Schumacher’s condition on Wednesday – exactly a month after his crash. She said then that his condition remained “stable”.
In her statement on Thursday, she said it had been agreed to communicate details of his sedation “only once this process was consolidated”.
