Hey there! Bruce Willis was first diagnosed with aphasia in 2022, which is a condition that impacts a person's ability to communicate.

In 2023, his family announced that his condition had progressed to a more specific diagnosis of frontotemporal dementia (FTD).

FTD is a neurological condition that is caused by changes in the frontal and temporal lobes of the brain, affecting things like language, personality, and behavior.
