The general music director of the Staatsoper Unter den Linden, Daniel Barenboim, will not be conducting for a long time.
Barenboim has announced that he will be withdrawing from some of his performances, especially conducting, for health reasons in the coming months, the State Opera said.
Barenboim had previously announced his withdrawal via social networks.
The musician wrote: "My health has deteriorated over the past few months and I have been diagnosed with a serious neurological condition." He needs to focus on his physical well-being as much as possible now.
The 79-year-old Barenboim had failed as a conductor several times in the past and most recently resigned from the Berlin new production of Wagner's "Ring".
In February he had to undergo surgery on his spine, then an inflammatory vascular disease forced him to be hospitalized.
"Music was and is an essential and enduring part of my life," Barenboim wrote on Facebook.
He has lived his whole life through music and will continue to do so as far as his health allows.
When he looks back and forward, he is not only satisfied, but deeply fulfilled.
