Bruce Willis' family shared the news on social media.

Action star Bruce Willis has been diagnosed with aphasia, his family revealed on social media Wednesday. Due to this, the 67-year-old actor will be "stepping away" from acting.

The family shared the news on social media, writing, "To Bruce's amazing supporters, as a family we wanted to share that our beloved Bruce has been experiencing some health issues and has recently been diagnosed with aphasia, which is impacting his cognitive abilities."

"As a result of this and with much consideration Bruce is stepping away from the career that has meant so much to him," the caption added.

Aphasia is "a condition that robs you of the ability to communicate," according to Mayo Clinic, and it "can affect your ability to speak, write and understand language, both verbal and written."

The condition "typically occurs suddenly after a stroke or a head injury. But it can also come on gradually from a slow-growing brain tumor or a disease that causes progressive, permanent damage (degenerative)," adds the Mayo Clinic.

"We are moving through this as a strong family unit, and wanted to bring his fans in because we know how much he means to you, as you do to him. As Bruce always says, 'Live it up' and together we plan to do just that," they concluded, signing the note from the actor's daughters Rumer Willis, Scout Willis, Tallulah Willis, Mabel Willis, and Evelyn Willis, plus Bruce's wife Emma Heming Willis and his ex-wife Demi Moore.

Our thoughts go out to Bruce, his family, and his friends.
