Billy Joel cancels all tour performances after revealing mysterious health diagnosis

Billy Joel has canceled all tour performances after being diagnosed with normal pressure hydrocephalus (NPH).

“This condition has been exacerbated by recent concert performances, leading to problems with hearing, vision and balance,” the 76-year-old musician said in an Instagram post Friday.

In light of his diagnosis, the “Vienna” hitmaker has started “undergoing specific physical therapy” and doctors have “advised [him] to refrain from performing during this recovery period.”

NPH is a medical condition defined as taking place when “too much” cerebrospinal fluid builds up in the brain’s ventricles, which can, in turn, lead to brain damage.

The rare disease typically affects older adults and its symptoms resemble those of Alzheimer’s and Parkinson’s disease, according to Johns Hopkins.
