Two months after singer Glen Campbell’s death from Alzheimer’s disease, his widow and primary caregiver, Kim, is expanding her mission to help others. She learned a lot about the disease and how to cope with it, as a caregiver, since Campbell’s diagnosis in 2011, and wants to use that experience to educate people on caregiving.

“When the doctor used the ‘A’ word, it just terrified me and shocked me, I really didn’t know much about it,” she said. “But I started to ask questions: Is it fatal? He said, ‘yes.’”
