Billy Joel, the arena-filling everyman singer-songwriter, has canceled all of his upcoming concerts, including a large-scale tour scheduled for this year and next, because of a brain disorder known as normal pressure hydrocephalus, he announced today.

“This condition has been exacerbated by recent concert performances, leading to problems with hearing, vision and balance,” said a statement posted to the singer’s social media accounts. “Under his doctor’s instructions, Billy is undergoing specific physical therapy and has been advised to refrain from performing during this recovery period.”

Normal pressure hydrocephalus, or NPH, is a rare condition that occurs when excess cerebrospinal fluid builds up in the brain, causing symptoms including trouble walking and controlling one’s bladder.
