Billy Joel has shared that he is feeling better following brain surgery that helped ease some of the symptoms of normal pressure hydrocephalus, a condition he was diagnosed with in 2025. During a recent appearance on SiriusXM's Billy Joel channel, the singer talked about the decision to undergo surgery after experiencing balance problems and a peculiar sensation. Normal pressure hydrocephalus is a neurological condition in which excess cerebrospinal fluid builds up in the brain's ventricles, leading to symptoms such as difficulty walking, memory issues, and urinary incontinence. While the exact cause is not always clear, it can sometimes result from previous brain injuries or infections. The condition is treatable, and one common treatment is the placement of a shunt, a small tube that helps drain the excess fluid to another part of the body where it can be absorbed. Joel described the experience of noticing changes in his balance and the strange sensations he was feeling, which prompted him to seek medical attention. After being diagnosed, he opted for surgery to address the issue. The procedure, which is relatively common for this condition, aims to relieve pressure on the brain by redirecting the flow of cerebrospinal fluid. The singer expressed gratitude for the support he has received from fans and medical professionals alike. While he did not go into detail about the surgery itself, he emphasized that the procedure has made a positive difference in his quality of life. Joel remains active in his music career and continues to connect with fans through various platforms, including his SiriusXM channel.
