We'll share that coming up. You have something special. You spoke to Kimberly williams-paisley. Normally very private. She thought it was important to come and speak. She did. You know her, Kimberly williams-paisley. A surprise revelation. Something that the family has been dealing with personally. Her Hurd, brad paisley, you know very well. It's about fatsing her mother's form a form of dementia. There was a beautiful essay she wrote in the new issue of "Redbook." She says this is their story of dealing with it. We first got to know Kimberly williams-paisley as the daughter in "Father of the bride." I'men gauged, I'm getting married. Reporter: If real life, she's the wife of country music superstar of brad paisley. And the mom of two boys. A working mop, she was glad her role on Nashville kept her close to home. I was distraught that your character was killed off of "Nashville." You and me both. Shot through the heart by a stray bullet. Come on. What are the chances? They let me know in the summer. I have to take a step back and remember that this character of Peggy was only supposed to be in three episodes. So I'm lucky she lasted as long as she did. I have had the privilege of spending time with you and brad at home in Nashville. Can't believe how the little ones are growing up so. They do that. Our oldest is about to turn 7. We're guilty of babying the youngest. Where is that baby going? So, yeah, it's so fun, though. They're at a great age. As Kimberly watches her sons, Huck and jasper, thrive and grow, she's had to watch her mother, Linda Williams, succumb to primary aaphasia. Something Kimberly is finally ready to talk about publicly. My mother is finally at a point where my mother is okay for us to talk about it. There was a long time that she didn't want us to talk about it. We had to hide it and cover up for her. Protect her pride. I felt like we were at a point where our story could help other people. Before we can talk about where you are now and your family, take us back to those dark moments. She started showing symptoms about two years before she was diagnosed. Seemed stress-related. She had more anxiety. Show was fighting to find words more than she used to. It was my mom who came to us and said, something's wrong. I'm having trouble finding words. I'm having trouble writing my name on the checks at the grocery store. Had to be a frustrating time. She came to us and we said, you're not getting enough sleep. Finally, she convinced my dad to quietly go get tests done. We didn't know they were going through these tests for months. Then they sat us down one Christmas and said what her diagnosis was and that it was going to be five to seven years before she would need full-time care. And she's pretty much been right on schedule. And my dad was this the midst of it. And it's very dangerous for the care giver. People don't always realize that. I know my dad didn't realize it in the depths of where he was. It was hard for him to see the truth. That he was withering away. We finally convinced him that she needed to be put into a long-term care facility. And so I mean, I would juts say, to people going through it, to keep an eye on the care giver. And for those five to seven years, your mother had her own communication with your kids. That was fascinating. I thought she's not going to know my kids. What was so cool was seeing how she did interact with them in a way that I didn't interact with them. Both down on the floor, being really goofy and silly. My kids adored her. They played well together. You have to hang on to those moments. The mother that you grew up with is not the mother that you have now. Mm-hmm. How do you cope with that? I had to come to is being able to let go of the mother that I grew up with. Because she's not there. And, the pain came from looking at the person that's there now and comparing it to who was there. That's painful. But if I say good-bye to that person, who doesn't exist anymore and say hello on to this person that I still have a bond with, it's much easier to love her and to be with her. And being with her mother now also means learning a new way of expressing love for each other. My mom used to be very articulate and was one of the best listeners in our family. Communication with her now is very different. She communicates on an emotional level. And music is very effective way of xhup kating with her. I was just with her. I sang a song that she knew, her face would light up. I sang a song she didn't know, it wouldn't. There are still some memories there. That's a way of engaging with her. What was the song you sang? "You are my sunshine" an old classic. An oldie but a goody. They emphasize that every family, it's different for everyone. This is how it is now. She said something fascinating. A lot of times people dealing with this form of dementia, they have an outburst. It's a shout. Kimberly was taught by her dad to match in the volume of the shout and then bring it down. That's a held offul hint. She matches it because she wants to say I'm hearing you, I relate, but then brings it down. A Sult way. Just finding different ways of communicating with her mom. The whole idea of not letting go but saying that mom is not here anymore. But I still have this mom. And I can appreciate the time with this mom. Love those pictures of the grandkids there, too. If you have a chance, the "Redbook" essay is beautiful. I think it will truly help families dealing with this.
