The influence of ageism on the hallmarks of aging: Where age stigma and biology collide.

Ageism encompasses the creation of negative stereotypes of aging that culminate in the development of prejudicial thoughts and discriminatory actions against people in advanced age. Stereotypes refer to major characteristics, overgeneralized, not supported by observations, that are created to categorize, simplify, and combine complex characteristics, attributes, and behaviors shared by members of a group into more simplistic categories. Negative aging stereotypes include the assumption that old people are weak, reminiscent, sick, and tired, to quote a few. In early age, these views may generate intergenerational conflicts between young and old people, but they seem to have little effect on other aspects of life. However, in middle-aged and older adults, the presence of negative-self stereotypes of aging are significantly associated with several health parameters, including walking speed, cognitive function, mental health problems, accumulation of amyloid plaques and neurofibrillary tangles. Furthermore, observational studies have found that ageism might be associated with cardiovascular events, obesity, dementia, and death. These harmful effects are possibly mediated by the interaction between ageism and fundamental mechanisms of aging, mainly inflammation. Given the clinical implications of this relationship, the present manuscript provides a critical review of the available literature that examined associations between ageism and health parameters. We also discuss the main possible mechanisms underlying this scenario, the main limitations of the current literature, candidate strategies to counteract ageism, and directions to future studies. Finally, we provide a critical opinion of the current scenario and its potential adaptability to the clinical practice.
