A standardized questionnaire was sent to family members or care-givers of 105 patients with dementia; 68 were returned. Eighty-eight percent of the patients were cared for at home by their spouses or adult children. The adverse impacts of dementia on patient family''s economy, relations among family members, and social life are recognized. The majority of the subjects had only limited understanding of dementia. Having medical insurance helps the family in caring for the demented patients, emotionally and socially, but not financially. A better social welfare system, as well as health insurance, is recommended.
