Contrary to the widespread belief that most elderly persons are institutionalized, 95 percent of people over age 65 live at home, and many are cared for, to some extent, by a relative. It has only recently been recognized that the family caregiver is at risk for increased physical and mental morbidity because of this often stressful task. If the situation is too stressful, elder abuse may result. Family physicians are in a good position to identify caregiver stress, recognize the danger signs of elder abuse, provide support, education and advice, and intervene when necessary. Primary care providers should routinely ask about caregiving responsibilities when obtaining the medical history of any patient over age 45.
