Lisa Rinna has talked about the terrible health problems her daughter Delilah Hamlin had as a child, saying that some of them were so bad they changed her life.

Rinna wrote about how she dealt with Delilah's pediatric autoimmune neuropsychiatric disorders linked to streptococcal infections (PANDAS) while raising her younger daughter, Amelia, in her new book, You Better Believe I'm Gonna Talk About It, according to Reality Blurb, on March 2, 2026.

Introducing the diagnosis, Rinna wrote, "At eleven years old, she was diagnosed with [PANDAS], which can start with a strep infection then manifest into tics and severe obsessive-compulsive behavior. Don't ask me how, they're still studying it and it's extremely rare."

She described the extreme effects of the illness on Delilah's daily life. "This thing got a hold of her, and she started to have expansive panic attacks. She was screaming, yelling, pounding on the windows of our house trying to get out. It was terrifying," Rinna recalled.

Rinna also highlighted how her daughter's disorder limited ordinary activities. "There was a point where she wouldn't go to school unless Harry came and sat outside the classroom for four hours. And he did it. She didn't want me, she wanted Harry," Rinna said, referring to her husband, actor Harry Hamlin.

Reflecting on particularly frightening incidents, Rinna explained, "The panic would creep in again, almost like the sundowning patterns dementia patients exhibit. I would sit with her and pull her away from the windows as she was screaming and pounding on them to try to get out. One time, she was having one of these attacks—melting down, screaming, almost like she was possessed by the devil—when Harry scooped her up, put her in the car, locked the doors, and drove her to the hospital, all while she was yelling and kicking," per Daily Mail.

Rinna called Delilah's PANDAS battle "the most devastating time" in their lives. "I felt helpless, and I was anxiety-ridden 24-7. We didn't know what we could do for her, and we didn't know if it would ever get better. We felt we lost our child and would do anything in our power to get her back," she added.

She also addressed the impact on her younger daughter, Amelia. "She was also put in the position of not daring to rock the boat because everyone was already so worried about Delilah. Nobody meant to neglect Amelia, and I don't think we did. But our focus was on Delilah. It really did take a village to help my family through this time," Rinna said.

Separately, Rinna admitted to incentivizing her daughters to appear on "RHOBH." On Jesse Tyler Ferguson's podcast Dinner's on Me, she shared, "They just didn't wanna film. I remember that. And I would have to bribe them to film because, of course, they would want the kids. And I would be like, 'Okay, I'll buy you this. You just come film for like 15, 20 minutes.'"

Delilah, now 27, has since battled depression alongside her earlier health challenges, highlighting the ongoing resilience required by the family.
