On May 23, Joel, 76, announced he would be canceling all scheduled concerts while revealing in a statement to People that he was recently diagnosed with normal pressure hydrocephalus (NPH), a brain condition caused by excess cerebrospinal fluid buildup in the brain ventricles that can affect memory, movement and concentration. "I'm sincerely sorry to disappoint our audience and thank you for understanding," Joel said.
