I think the aphasia is just a symptom of another health problem. I noticed that in all the recent photos of him, he's wearing something on top of his head. I'm wondering if it was a tumor that was removed and the aphasia is a side effect. All the best to him and his family. ****Additional information from the LA Times*** Hollywood had noticed a decline in Willis' decline in recent years. His contracts limited his work to just a couple of days and limited to only eight hours, although he would often only work four. Requests to reduce the amount of dialogue and he was fed lines via an earpiece. Willis did 22 films in four years.
