The "Euphoria" and "Grey's Anatomy" star, who revealed his diagnosis last Tuesday, sat down with "Good Morning America" to talk about his incurable condition.

Eric Dane — who revealed in April that he was diagnosed with ALS — shared that despite his “setbacks,” he has no plans of giving up his acting career.

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.
