Minuteman Senior Services will offer a workshop for caregivers of persons with dementia from 2:30 to 4:30 p.m. Tuesdays, Sept. 12 to Oct. 17, with the Woburn Council on Aging.Called the Savvy Caregiver Program, this six-week evidence-based workshop acknowledges that taking care of a person living with Alzheimer's disease or other dementia-related illness is specialized work.
