Eric Dane's Memoir Reveals the Diagnosis He Got Before ALS--and Why It Didn't Stick

Eric Dane’s posthumous memoir“My Book of Days”arrived Tuesday, November 3, and it pulls back the curtain on a medical journey that started with a visit to a hand specialist and ended in a diagnosis nobody wanted. Along the way, doctors first told him he had multifocal motor neuropathy, a rare autoimmune disorder. They said the treatment worked 90 percent of the time. His body didn’t respond, and his doctors were scared.

What followed was nine more months of testing, including lumbar punctures and brain scans, before the ALS confirmation came in late 2024. Dane called it a death sentence and said his life had become a horror movie. He went public in April 2025 and died less than a year later at 53, leaving behind daughters Billie, 16, and Georgia, 14, and ex Rebecca Gayheart, who asked for privacy.

The book isn’t really about Hollywood. It’s about the long, frustrating road to answers, and how fast a treatable diagnosis can turn into a much harder one. Have you ever had a diagnosis change on you after months of waiting? Tell us your story.
