It was mailed to ninety-nine caregiver of the family with the aged with dementia who cared them at home utilizing day-care service at a special nursing home for the aged, and attended family class once a month. 67 valid answers were obtained. The average age of caregiver was 57.0 years; seventy-six percent of them were female. Their difficulties were own health condition and lack of a cooperator for care.
