Tallulah Willis reveals missed signs of Bruce Willis' dementia diagnosis.

Tallulah Willis, daughter of Bruce Willis and Demi Moore, has opened up about her father's diagnosis of frontotemporal dementia in an essay for Vogue magazine. Willis reveals she's "known that something was wrong for a long time." She initially thought her father had "lost interest" in her after having two daughters with wife Emma Heming. Willis says she struggled to accept Bruce's worsening condition due to the turmoil of her four-year battle with anorexia nervosa. Now in recovery, Willis says she's able to approach her relationship with her father with a healthier perspective.
