There are many potential causes of aphasia. It often occurs after a stroke or head injury, but can also develop gradually due to a slow-growing brain tumor or a disease that causes degenerative damage, like Alzheimer’s disease. It’s treated primarily with speech therapy and learning non-verbal means of communication.

Willis’ family didn’t divulge what caused his aphasia. Representatives for the actor declined to comment.

Willis had been working steadily and frequently. Renowned for films like "Die Hard," "Pulp Fiction" and "The Sixth Sense," Willis has in recent years churned out straight-to-video thrillers. Last year, he starred in a staggering eight films. Most came and went quietly, including titles like "Cosmic Sin," "Out of Death" and "Deadlock."

Most recently, Willis starred in February’s "Gasoline Alley" and "A Day to Die," released in early March. Willis has already shot at least six more films due out in 2022 and 2023, including "Die Like Lovers," "Corrective Measures" and "The Wrong Place."
