normal pressure hydrocephalus

Even if his soul should still rock and roll with me.

Last year, Joel revealing he was diagnosed with normal pressure hydrocephalus, or NPH, a neurological condition that causes complications including difficulty walking, balance, and memory loss.

His diagnosis following concerning onstage incidents when the five-time Grammy winner was seen falling during concerts.

Joel now sharing why living with NPH makes performing difficult.

"The volume.

Rock and roll is loud, man.

This could explain why some people develop this rebound intracranial hypertension and then other fistula.

So maybe they started from a, like hypertensive state or an NPH state, and then they have it again.

And we had two patients that continued to have recurrences, and ultimately, we shunted them to avoid rebound intracranial hypertension.

We told them this was very experimental.

Uh, I think he's recorded something like 40 albums.

Anyway, look, his fans were really worried, apoplectic with worry after he fell over on stage, in fact fell off stage, uh, off the stage in Connecticut, then canceled a string of concerts and it was a mystery as to what was bedeviling him and then he revealed that he'd been diagnosed with this rare, complicated and serious brain issue known as NPH or normal pressure hydrocephalus, um, which is kind of like a fluid on the brain thing, which builds this massive pressure in the skull and that was affecting his balance and sending him toppling over, also affecting his speech and his memory.

Makes total sense as to why he had to cancel those concerts.

Look, he recently underwent surgery, he said, which necessitated a hole to be drilled in his skull and a shunt was implanted to drain away the excess fluid.
