The process of waking up Michael Schumacher from an artificial coma is "unchanged", his manager said on Monday.
"This phase can take a long time, which much to our regret can lead to many misinterpretations," Sabine Kehm, Schumacher's manager, told dpa.
The news magazine Focus reported on Monday that the waking up process had been halted.
Schumacher, 45, suffered severe head injuries in a skiing accident at the French resort of Meribel on December 29.
The seven-time World Champion was taken to a hospital in Grenoble where he was placed in an artificial coma.
