The family of Bruce Willis announced Wednesday that the actor has been diagnosed with aphasia, a neurological condition that affects a person’s ability to understand and communicate with others.

As a result, the “Sixth Sense” and “Die Hard” star is “stepping away” from acting, his loved ones said in a heartfelt statement. According to the National Aphasia Assn., the condition is an acquired communication disorder that impairs the ability to process language, but does not affect intelligence.
