In the absence of effective pharmacological therapy options, the focus of dementia and Alzheimer’s research has shifted from treatment and care to risk prediction, early detection, and prevention. Public health communication and media coverage regarding dementia emphasize the individual responsibility for dementia risk management. Focusing on the social and moral implications of the new understanding and public representation of dementia, we present an analysis of medical science, nursing science, and media discourses in Germany between 2014 and 2019. We show which notions of dementia and prevention characterize the medical and nursing science debates regarding dementia and how scientific knowledge is transferred into media discourses on dementia. We further discuss how dementia risk communication interacts with contemporary social and health policies and in what ways current dementia discourses are associated with a (self-)responsibilization of cognitive aging.

在缺乏有效的药物治疗选择的情况下，痴呆症和阿尔茨海默氏症的研究重点已从治疗和护理转向风险预测、早期检测和预防。关于痴呆症的公共卫生传播和媒体报道强调了个人对痴呆症风险管理的责任。专注于痴呆症的新理解和公众代表的社会和道德影响，我们对 2014 年至 2019 年德国的医学科学、护理科学和媒体话语进行了分析。我们展示了痴呆症和预防的哪些概念是医疗和预防的特征。关于痴呆症的护理科学辩论以及科学知识如何转化为关于痴呆症的媒体话语。
