Bruce Willis

Bruce Willis is a vulgar, wisecracking man-child, and Cybill Shepherd is a classy tough broad horrified by his shenanigans. But cliché premise notwithstanding: it was a sharp, experimental show.

When a dire disease strikes, it's easy to slip into war terms to describe the experience. But that sort of talk turns life into two outcomes: winning and losing. And that's not the way life works.

Willis family announced Thursday that his previous diagnosis of aphasia has progressed to frontotemporal dementia. The disease can cause issues with speaking and writing.

While details of Willis' diagnosis are unknown, medical experts stress the importance of the brain condition and how it's specifically treated — depending on its severity.
