Actor Russell Andrews, known for his roles in and , has revealed that he has been diagnosed with ALS.

ALS, or amyotrophic lateral sclerosis, is a fatal neurodegenerative disease that "often begins with muscle twitching and weakness in an arm or leg," according to Mayo Clinic.

Andrews' announcement comes three months after fellow actor Eric Dane died following a battle with the disease. Dane, who portrayed Dr. Mark Sloan on the long-running medical drama, died in February, 10 months after publicly disclosing his ALS diagnosis.

"I am a person living with ALS," Andrews, 64, said during an appearance on CNN's on Saturday.

"I was diagnosed in the late fall of last year," he added. "It's been humbling. But there's also something in the fact that I walked into a family of very caring people. People I did not know a year ago."

Andrews appeared on the segment alongside his fiancée, actress Erica Tazel, and said he initially believed he had suffered a stroke during the Covid-19 pandemic.

"It was a stressful time," he explained. "There were moments. There were twitches. There were things that I thought I was having pinched nerves in my neck. And they were quite frequent. But then I was not able to do things I was normally able to do."
