In recent years, supported decision-making (SDM) has gained traction as a recognized alternative to guardianship for persons with disabilities in the United States. To date, SDM has not been as widely recognized as an alternative for older people, particularly those struggling with cognitive decline. This paper explores some of the obstacles that have prevented SDM from being used more broadly by older people, identifies ways of surmounting some of those obstacles, and makes recommendations for ways that SDM can be used in the aging context.
