According to the Alzheimers Association, FTD refers to "a group of disorders caused by progressive nerve cell loss in the brain's frontal lobes."
FTD is different from Alzheimer's. FTD affects people's behavior and language more than their memory although advanced FTD can cause memory loss.
Additionally, those diagnosed with FTD are typically in their 40s or early 60s.
There is no treatment for the disease.
Celebrities sent their love to Willis and his family including Maria Shiver and Jake Tapper.
