Billy Joel has been diagnosed with normal pressure hydrocephalus. What is this brain condition?

The 76-year-old is currently undergoing “specific physical therapy” and is taking a break from the music scene. In a statement shared on Instagram, he thanked his fans for their “support” and apologised for cancelling all scheduled concerts. 

NPH is a brain disorder in which excess cerebrospinal fluid (CSF) accumulates in the brain's ventricles. This excess fluid causes the ventricles to enlarge and press against nearby brain tissue, which can potentially lead to brain damage, according to the Johns Hopkins Medical website. 

While NPH is rare, it “most often affects older adults, and its symptoms can be like those of Alzheimer and Parkinson diseases,” the website adds. In Joel's case, “this condition has been exacerbated by recent concert performances, leading to problems with hearing, vision, and balance,” according to the statement shared on his social media handle.

“Under his doctor's instructions, Billy is undergoing specific physical therapy and has been advised to refrain from performing during this recovery period,” it adds. The Uptown Girl singer is “thankful for the excellent care he is receiving and is fully committed to prioritizing his health.” 

“He is grateful for the support from fans during this time and looks forward to the day when he can once again take the stage,” per the statement. Meanwhile, Joel said, “I'm sincerely sorry to disappoint our audience, and thank you for understanding.”
