Each year, an estimated 44 million American caregivers provide $257 billion worth of care to their family members and friends. Few are trained — physically or emotionally — to take on roles traditionally performed by nurses and social workers caring for someone with a chronic illness. Physicians sometimes call family caregivers hidden patients because so many neglect their own health and well-being while taking care of others. Caregiving for Alzheimer's is particularly difficult, and it is critical to tap into the resources and get the support you need.
