After being diagnosed with the language condition aphasia, Bruce Willis' family announced his retirement from acting on Wednesday.

According to the American Speech-Language-Hearing Association, aphasia is a "acquired neurogenic language disease" that affects the understanding and expression of written and spoken language and commonly happens after a stroke or a brain injury. While speech and language treatment can help persons with aphasia restore their language abilities, it is "typically a rather slow process," and while "most people make considerable improvement, few people reach their pre-injury communication levels," it is "generally a relatively slow process."

It's unknown what caused Willis' aphasia or if the "Die Hard" star has any additional disabilities.

"Our family is going through a very difficult time right now, and we are so grateful for your continuing love, sympathy, and support." "We are moving through this as a strong family unit, and we wanted to bring his fans in because we know how much he means to you, as you do to him," read the statement, which was signed by his wife, Emma Heming; ex-wife, Demi Moore; and his other four children and was posted to Instagram by his daughter Rumer.
"As Bruce often says, 'Live it up,' and that is exactly what we want to do together," the statement said.
