The US singer-songwriter, Billy Joel, has been diagnosed with a brain disorder that’s forced him to cancel all his upcoming concerts across North America and England.

Joel used his Instagram to reveal that he has Normal Pressure Hydrocephalus, a fluid buildup in his brain that affects his “hearing, vision and balance”.

“This condition has been exacerbated by recent concert performances, according to a statement from Joel’s team. “Under his doctor’s instructions, Billy is undergoing specific physical therapy and has been advised to refrain from performing during this recovery period.”

In an accompanying statement, Joel said, “I’m sincerely sorry to disappoint our audience, and thank you for understanding.”

In March, ‘The Piano Man’ and ‘Uptown Girl’ singer announced that he underwent surgery and had to undergo physical therapy. A statement at the time said doctors expected him to make a full recovery. It is unclear if his medical issues at the time were related to Normal Pressure Hydrocephalus.

The condition can cause problems with walking, bladder control and thinking, with symptoms worsening if left untreated. It’s relatively rare and can be hard to diagnose. It can be treated successfully with surgery to install a tube to drain excess fluid. Patients may need physical therapy in addition to surgery.

Joel, 76, wrapped up his decadelong residency at Madison Square Garden in July 2024 and continued to tour. His planned summer stops included shows at Yankee Stadium and Citi Field in New York, and MetLife Stadium in East Rutherford, New Jersey.

Tickets for all the shows will be refunded.
