(NewsNation) — Bruce Willis’ wife, Emma Heming Willis, knew something was “off” with the “Die Hard” actor when she noticed a change in the way they communicated.

“There were conversations that I recalled differently than Bruce did, and there seemed to be a lot of miscommunications between the two of us. Sometimes I'd think, 'Is he for real? Is he pretending? Or am I going crazy?' The disconnect was subtle but happening more and more,” she writes in her book “The Unexpected Journey: Finding Strength, Hope and Yourself on the Caregiving Path.”

The book, which was released on Tuesday, is described as “for anyone caregiving for a loved one with any form of dementia, and even for those caregiving for other conditions, 'The Unexpected Journey' shows that you are not alone.”
