New Delhi, Aug. 26 -- Emma Heming Willis, the wife of actor Bruce Willis, has shared a heartfelt update on her husband's health and spoken about the reality of caring for someone with dementia.

Speaking to Diane Sawyer in an ABC News special titled 'Emma & Bruce Willis: The Unexpected Journey', Emma explained that while Bruce remains physically strong and mobile, it's his mind that's struggling.

"Bruce is in really great health overall," she said. "It's just his brain that is failing him."

Emma shared that the family has had to adapt to new ways of connecting with Bruce. "The language is going, and we've learnt to adapt," she said. "We've found a different way to communicate."
