Actor Eric Dane is opening up about his amyotrophic lateral sclerosis, or ALS, diagnosis.
Dane, who famously played Dr. Mark “McSteamy” Sloan on “Grey’s Anatomy,” got emotional talking about the journey with ABC’s Diane Sawyer.
“I wake up every day and I’m immediately reminded that this is happening,” he told Sawyer in the teaser clip released on June 12. “It’s not a dream.”
The full interview with Dane and Sawyer will be aired on Good Morning America on June 16.
“I don’t think this is the end of my story. I don’t feel like this is the end of me,” he explained.
The “Euphoria” star revealed his diagnosis to PEOPLE magazine in April.
“I have been diagnosed with ALS,” he said. “I am grateful to have my loving family by my side as we navigate this next chapter.”
ALS, a neurogenerative disease also referred to as Lou Gehrig’s disease, is a “condition that affects how nerve cells communicate with your muscles,” the Cleveland Clinic’s website explains. It leads to worsening muscle weakness over time, and there is currently no cure.
The causes of ALS are still being studied, though it is believed that around 10% of cases are passed down through genetics, according to the Mayo Clinic’s website.
“Researchers continue to study possible causes of ALS. Most theories center on a complex interaction between genes and factors in the environment,” the site claims.
Despite the diagnosis, the 52-year-old is set to return as Cal Jacobs for the upcoming third season of “Euphoria.”
Dane is married to actress Rebecca Gayheart they have two teenage daughters.
