Actor Eric Dane has opened up about his battle with amyotrophic lateral sclerosis (ALS) and is revealing the one symptom — the very first one — he experienced, but didn’t think much of at the time it happened. The former “Grey’s Anatomy” star, 52, revealed this important fact to Diane Sawyer in a new interview on “Good Morning America” Monday.

Grey's Anatomy star Eric Dane has opened up about his health journey after revealing he was diagnosed with ALS earlier this year.

He emphasized his perseverance moving forward, saying, “I’m fighting as much as I can,” though he admitted, “There’s so much about it that is out of my control.”
