Michael Schumacher's agent is confident he will eventually wake up from his coma, according to Reuters.
There are 'small' and 'encouraging' signs in his medical development but Sabine Kehm, his agent and spokeswoman recognises this process will take time.
"We are and remain confident that Michael will pull through and will wake up," she wrote in a written statement.
"There sometimes are small, encouraging signs, but we also know that this is the time to be very patient."
Formula 1 legend Schumacher hit his head in a skiing accident in December and was airlifted to hospital.
However, the extent of the head injuries only became apparent later on and he was put into a medically induced coma.
He had been skiing in an 'off-piste' section of the resort where he fell and hit his head on a rock that was covered by snow.
'Off-piste' refers to parts of the resort that are unmarked or unmaintained, and people are normally recommended not to ski in these types of areas.
"It was clear from the start that this will be a long and hard fight," Kehm said.
"Michael has suffered severe injuries. It is very hard to comprehend for all of us that Michael, who had overcome a lot of precarious situations in the past, has been hurt so terribly in such a banal situation."
