Billy Joel has revealed that doctors diagnosing his Normal Pressure Hydrocephalus told him his loud rock concerts were likely causing damage to his brain, prompting the singer to halt touring. In an interview on his SiriusXM channel, the 77-year-old explained that after suffering balance problems, he was advised to undergo surgery to fit a shunt in his brain, which improved his memory, balance and overall function, but his medical team also warned that performing gave him something akin to a concussion at every show.

Joel said he initially resisted the shunt surgery, which involves drilling into the skull, but agreed after learning it could help his memory and balance. His last full concert was on 22 February 2025 in Uncasville, Connecticut, where he stumbled on stage during a performance, an incident that led to his diagnosis; he cancelled his remaining 2025 tour dates three months later. Since then he has made only one public performance, joining a tribute band in Florida in January, though he has reassured fans he is doing well and undergoing physical therapy as he recovers.
