Bettina Vetina Henderson, 55, was found safe, authorities said. The alert was issued by the North Carolina Center for Missing Persons around 5 a.m. Wednesday.
Developed in 2007, the Silver Alert system quickly notifies the public about missing endangered adults who suffer from dementia or other cognitive impairments, such as Alzheimer's disease.
It also allows caregivers and nursing homes to report a person missing. In the past, only a family member could report an adult missing.
