Billy Joel Opens Up About Brain Disorder, Says 'I Feel Good'

Billy Joel revealed on Bill Maher's podcast that he has been diagnosed with Normal Pressure Hydrocephalus (NPH), a brain disorder affecting his balance, but he feels good overall and is receiving treatment. The condition, which was previously called 'water on the brain,' has led to some of his recent concert cancellations, but he remains optimistic about his recovery. The singer also discussed his career and personal life during the interview and the release of his HBO documentary.
