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 said the condition has been exacerbated by recent concert performances, leading to problems 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.

NPH is a brain disorder marked by a buildup of cerebrospinal fluid in the center of the brain. According to the Hydrocephalus Association, the disorder can affect areas of the brain related to walking, thinking and bladder control.

In March, Joel postponed eight stadium concerts he had scheduled through July, citing an undisclosed medical condition and saying that his health must come first.

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.
