Aging affordances: Navigating expectations of dementia prevention for aging adults in Canada

Dementia prevention now focuses on individual lifestyle choices as loci of intervention in the hope of delaying or preventing cognitive impairment in aging. Drawing from interviews with dementia experts and middle-aged adults in Canada, we discuss how prevention expectations compete with adults' experiences, showing that enacting prevention is not simple but rather fraught with tensions. Addressing the troubles of prevention, we propose aging affordances as the particular ways mid-life adults construct, make sense of, and act toward their aging process, including how they navigate expectations of prevention amidst tensions that fashion their relationships with their environment. We take the environment in a broad sense to include social and cultural systems of values and discourses, such as dementia prevention recommendations. It allows us to turn the preventive focus on its head, looking not at its normative behavioral prescriptions but at the range of possibilities mid-life adults strive for as they age.
