VDT

Beville, who first studied the relationship of caregivers to aging patients in the 1980s as a postgraduate in clinical psychology, has been selling VDT kits since 2003.

Along with 35 employees and associates of the Sunrise Senior Living Community in McLean, I was taking a class for caregivers that its creator calls VDT -- the Virtual Dementia Tour.

Next month, Sunrise communities in Northern Virginia will host VDT demonstrations for people caring at home for relatives with dementia.
