Now, however, the actor has shared a few more sobering updates about his health on Good Morning America. “My right side has completely stopped working,” he told the program. Dane said that he expects to lose control of the left side as well.

Grey’s Anatomy and Euphoria star Eric Dane revealed he was diagnosed with amyotrophic lateral sclerosis (ALS). And, most recently, he opened up about his battle with the incurable disease in a sit-down with Diane Sawyer for Good Morning America.

Dane -- who shot to fame amid six seasons on the hit ABC drama "Grey's Anatomy," where he played Dr. Mark Sloan, affectionately known as "McSteamy" -- said his symptoms began over one year ago, when he began to experience weakness in his right hand.
