The mission of TEDMED is to promote ideas and conversations on health care issues through open dialog with an intellectually diverse community. TEDMED has launched a Great Challenges of Health and Medicine Program. Great Challenges are defined as complex, persistent problems that have medical and non-medical causes, impact millions of lives and affect the well-being of all of America. This year's challenges include caregiving, end-of-life, impact of poverty on health and promoting active lifestyles. Barry Jacobs, PhD, director of Behavioral Sciences at Crozer-Keystone Family Medicine Residency Program (and a member of the APA Presidential Task Force on Caregivers that developed the APA Family Caregivers Briefcase) was selected as a Challenge Team expert member for the Caregiver Crisis challenge. Team members participate in real-time, multi-disciplinary dialogue and create responses to questions submitted by the community. Conversations among Challenge Teams will take place through next March on the TEDMED website and during a series of live web-based sessions.
