Eric Dane is determined to fight "to the last breath" amid his ALS (amyotrophic lateral sclerosis) battle.

The 52-year-old actor - who revealed in April he had been diagnosed with ALS, also known as motor neurone disease - has two daughters, Billie, 15, and 13-year-old Georgia, with this wife Rebecca Gayheart, and he is desperate to see the teenagers "get married" and "have grandkids" one day.

Speaking in a TikTok video shared by US Representative Eric Swalwell, of California, Dane told the lawyer and politician: "I have two daughters at home. I want to see them, you know, graduate college, and get married and maybe have grandkids.

"You know, I want to be there for all that.

"So, I'm going to fight to the last breath on this one."

The Euphoria star's latest comments came in a meeting in Washington, DC, alongside members of non-profit organisation I AM ALS.

Dane is backing ACT for ALS, which aims to accelerate the development of treatments for ALS and other rare neurodegenerative diseases.

He added in the video: "ALS is the last thing they want to diagnose anybody with.

"So often, it takes all this time for these people to be diagnosed, well, then it precludes them from being a part of these clinical trials.

"That's why ACT for ALS is so great, because it broadens the access for everybody."

Last week, Rebecca said Eric and his family are focusing on professional support as they navigate life following his ALS diagnosis.

She explained: "We have some professional therapists who are helping us, and we're just trying to have some hope and do it with dignity, grace and love.

"I mean, it's heart-breaking.

"My girls are really suffering, and we're just trying to get through it. It's a tough time."
