Kimberly Williams-Paisley on her late mother’s Alzheimer’s diagnosis and her mission to help others

Everyone forgets a word now and then, quickly flipping through the mind's mental Rolodex of vocabulary only to come up empty. But for actress Kimberly Williams-Paisley’s mom, her struggle to find the right word in conversation was worrying her — and it was happening frequently. In 2006, her 62-year-old mother got a diagnosis: a frontal temporal lobe disorder called primary progressive aphasia — a rare neurological syndrome that affects one’s ability to communicate, according to the Mayo Clinic. The condition eventually leaves people unable to speak, write, or read. “We didn’t know it was officially Alzheimer’s until after she passed away,” Williams-Paisley shares with Yahoo Lifestyle. “There’s no way to definitively diagnose Alzheimer’s until after death.” But at the time of the initial diagnosis, Williams-Paisley says, “It was heartbreaking.” She adds: “I was pregnant, and I was devastated that she wasn’t going to know my kids. I figured I’d probably, hopefully, have more than one, and I knew that she wouldn’t be in their lives the way she’d been in mine.” The actress, 47, who is best known for her 1991 role in the Father of the Bride movies with Steve Martin and is starring in “Darrow & Darrow: Body of Evidence,” premiering Oct. 14 (9pm ET/PT) on Hallmark Movies & Mysteries, describes her once-vibrant mother as a “real go-getter.” “If there was an ocean, she was in the ocean,” she says. “It didn’t matter if it was cold — she would jump in. That, to me, encapsulates my mother’s spirit.” However, along with her diagnosis came feelings of shame. Williams-Paisley, who is married to country star Brad Paisley, says that her mom was “very embarrassed” about her condition. “She insisted that we keep it a secret. She just kept saying, ‘If I could only just, if I just focus a little bit more I can do it.’” Kimberly Williams-Paisley is starring in “Darrow & Darrow: Body of Evidence,” which premieres Oct. 14 (9pm ET/PT) on Hallmark Movies & Mysteries.

Seeing her mom in long-term care and watching her personality slowly slip away was painful for Williams-Paisley. “It tortured me when I went to see her there because I just kept thinking of who she used to be," she recalls. "And that felt like a ghost.” Williams-Paisley eventually decided to put the “ghost” aside and accept who her mom was now. She looked for glimmers of light, noticing that her mom still loved music and lit up whenever someone walked into the room. “She still had that exuberance,” she says. Her mom died in 2016, which Williams-Paisley says was “gut-wrenching.” Before her mother’s death, Williams-Paisley wrote about the journey with her mom and the stigma of Alzheimer’s in the book Where the Light Gets In, to help others dealing with the effects of dementia. She continues to honor her mother’s legacy by raising money for the Alzheimer’s Association to help fund research, as well as by raising awareness about the devastating disease, which affects 50 million people around the globe. “In her healthy mind, I think she would have been so happy and proud,” Williams-Paisley says about her efforts. “And that’s the mom I want to remember, more than anything.” Read more from Yahoo Lifestyle: Alzheimer's symptoms are anything but normal — here's what you need to know How one savvy mom realized her 6-year-old's frequent trips to the bathroom were something more serious 'The pain was so bad, I went to the ER a few times': How birth control can work beyond pregnancy prevention Follow us on Instagram, Facebook, and Twitter for nonstop inspiration delivered fresh to your feed, every day.
