Kimberly Williams-Paisley is set to open up about a very personal issue.
In her upcoming book, Where the Light Gets In, to be published by Crown in 2016, the actress, 43, will share a glimpse of what life has been like since her mother, Linda, was diagnosed with a rare form of dementia called primary progressive aphasia at age 62.
“I hope that the whole story – and what we learned from its challenges, mistakes, moments of joy and unexpected humor – will help many more people, and promote further awareness of a heartbreaking epidemic,” Williams-Paisley said in a press release first obtained by PEOPLE.
The Father of the Bride star has shared her mother’s struggle before, but this new read promises an even deeper look.
“The overwhelming response to my Redbook piece showed me that my family’s ordeal resonated with others coping with a beloved parent’s disease,” she says in the release, which calls Where the Light Gets In the complete story of her mother’s illness, including the hardships, the memories, the details of their relationship, the strong bond that brought her family closer – and even the funny moments.
Williams-Paisley has said she’s learned to accept her mother for who she is now, all while welcoming the unexpected humor and grace that comes with the heartache.
“She is, in many ways, a ‘new’ mom. But now it’s easier to welcome memories of her as she used to be,” Williams-Paisley wrote in a personal essay for Redbook. “I remember her as I run, the way she always used to, into a cold ocean when no one else wants to. I’m sure I know how she felt as I listen to my own children with all my heart.”
Where the Light Gets In will be available March 29, 2016.
