NEW YORK, N.Y. () — Singer Billy Joel has announced he will cancel 17 scheduled concerts following a recent health diagnosis.

The Rock N Roll Hall of Famer has Normal Pressure Hydrocephalus (NPH).

In a statement, Joel and his team explained that recent concert performances have worsened his condition, causing difficulties with hearing, vision, and balance.

Under his doctor’s orders, Joel is said to be undergoing specific physical therapy and has been advised to stop performing while he recovers.

Normal Pressure Hydrocephalus (NPH) is a neurological disorder characterized by an accumulation of cerebrospinal fluid in the brain’s ventricles. This can impact brain regions responsible for movement, cognition, and bladder management, as noted by the Hydrocephalus Association.

Back in March, Joel delayed eight of his planned stadium concerts set for the months up to July, due to a medical issue he hadn’t previously disclosed, emphasizing the priority of his health.

At the time, the announcement said Joel was expected to make a full recovery after a recent surgery and was undergoing doctor-supervised physical therapy.
