Watch: Billy Joel Mourns Death of Former Bandmate Jon Small
Billy Joel recentlyunderwent a procedure to treat his brain condition.
The “Vienna” singer shared that he had a shunt implanted in his brain after being diagnosed with normal pressure hydrocephalus, a buildup of cerebrospinal fluid that puts pressure on the brain, per the Mayo Clinic.
“I noticed that my balance was not good. I have this sense of being on a boat, like this this rocking motion,” he shared on SiriusXM Sept. 9. “I wasn’t steady on my feet. I didn’t know why that was.”
His neurologist explained that his diagnosis could be “progressive” and recommended he implant a shunt—a medical tube—to drain excess fluid.
“I said, ‘Well, what does that entail?'” Joel recalled. “‘Well, we drill a hole through your skull and we stick a shunt inside your brain.’ I said, ‘Nah, I think I’ll pass on that.'”
However, the 77-year-old did some research and “realized it can help improve your balance and can help your memory.”
“I don’t want to lose my marbles. It’s hard to tell what’s age and what’s a condition,” he noted. “So, I agreed to do the shunt and I had a surgery.”
Indeed, Joel noticed “it actually improved things” for his health, saying, “My memory got better, my balance got a little better, my ability to function was better.”

And while Joel said “nobody’s sure” what causes hydrocephalus, his doctors believe his career as a musician contributed to his condition.
“The doctors told me this, because of my job, which is playing rock and roll music very loud, that it was giving me something like a concussion every time I did a show,” he continued. “It was causing damage to my brain nerves and I could be losing more brain cells the more I played, the more shows I did.”
That’s why he ultimately canceled all his concerts in May 2025 following his diagnosis.

“I realized that means I shouldn’t be doing this right now. I got to improve. They don’t want me to stress too much,” he shared. “So, I’m doing physical therapy. I’m doing whatever it is they tell me to do, because I don’t want to lose it, you know?”
But the “Uptown Girl” artist does want to assure fans that he’s “OK,” adding, “I just want people to know, don’t worry about me. I’m not going anywhere. I’m here. I’m still here.”
