Grim prognosis for Bruce Willis and all who suffer this form of dementia

It's common for people with fronto-temporal dementia to be misdiagnosed, as was the case with Bruce Willis.

In March last year it was reported veteran Hollywood actor Bruce Willis had lost the ability to communicate.

At that time he was diagnosed with aphasia – where sufferers speak in sentences that don’t make sense, use unrecognisable words and don’t understand other people’s conversation.
