Doctors treating legendary Formula One driver Michael Schumacher have lowered his sedation as a first step in bringing him out of a medically induced coma, the German racer's manager said Thursday.

"Michael's sedation is being reduced in order to allow the start of the waking up process, which may take a long time," Sabine Kehm said in a statement.

"For the protection of the family, it was originally agreed by the interested parties to communicate this information only once this process was consolidated."

No information will be provided about "intermediate stages" of Schumacher's recovery, she added.

The 45-year-old Schumacher, who won seven Formula One drivers' championships between 1994 and 2004 before retiring at the conclusion of the 2012 season, has been hospitalized for a month in Grenoble, France, after suffering a serious head injury in a Dec. 29 ski fall.

After undergoing two operations to relieve pressure on his brain, Schumacher was placed in a medically induced coma. EFE
