(CNN) -- Judy Warzenski didn't realize how bad her father, Donald's, memory had gotten until he turned to her sister Joyce and asked, "Where's the girl who was sitting next to you?" He did not recognize Joyce as his own daughter.
This Thanksgiving, Warzenski and her younger siblings will eat Thanksgiving dinner with their father in a private dining room at a nursing home in Pennsylvania. Moving her father there in October was an agonizing decision.
"It's really very upsetting to me," said Warzenski, 62, of central New Jersey. "I promised him I would never do this. I promised him I would never put him in a nursing home, which I've come to realize is an unrealistic promise."
Warzenski, who had commented on a previous CNN dementia story, is one of many baby boomers who must watch their loved ones suffer from Alzheimer's, the most common form of dementia. The condition, which robs people of their memory and thinking skills, necessitates tough decisions about caring for people as their minds slowly slip away.
"Often, the baby boomers are thrust into the position of caring for a loved one with dementia because that loved one declines and needs 24-hour supervision," said Laura Wayman, a dementia care specialist and author of "A Loving Approach to Dementia Care."
