Mild Cognitive Impairment (MCI) is a diagnostic category indicating cognitive impairment which does not meet diagnostic criteria for dementia such as Alzheimer’s disease. There are public health concerns about Alzheimer’s disease (AD) prompting intervention strategies to respond to predictions about the impacts of ageing populations and cognitive decline. This relationship between MCI and AD rests on three interrelated principles, namely, that a relationship exists between AD and MCI, that MCI progresses to AD, and that there is a reliable system of (...) classification of MCI. However, there are also several ethical issues and problems arising in the AD/MCI relationship. These include early diagnosis and interventions, the effects on people with MCI, and the newer neuroimaging and neuropharmacological approaches used in diagnosis and treatment. All these issues pose questions about the principles of MCI in relation to AD, with implications for how MCI is understood, diagnosed, treated, and experienced by patients. This article analyses four challenging areas for neuroethics: the definition and diagnosis of MCI; MCI in relation to AD; clinical implications of MCI for ethical disclosure, diagnosis, and treatment; and the research implications of MCI. The significant connections between these areas are often overlooked, together with uncertainties overall. Patients, healthcare systems and society are best served by informed clinicians, academics and researchers. After 35 years, the store of MCI knowledge is expanding and evolving. (shrink)

Anticipation of future decisions can be important for individuals at risk for diseases to maintain autonomy over time. For future treatment and care decisions, advance care planning is accepted as a useful anticipation tool. As research with persons with dementia seems imperative to develop disease-modifying interventions, and with changing regulations regarding research participation in Germany, advance research directives (ARDs) are considered a solution to include persons with dementia in research in an ethically sound manner. However, little is known about what (...) affected people deem anticipatable.This contribution provides a critical reflection of the literature on anticipation and of a qualitative study on the assessment of ARDs with persons with cognitive impairment in Germany. It combines theoretical and empirical reflections to inform the ethical-legal discourse.Anticipation involves the conceptual separation of the past, the present, and the future. Including dimensions such as preparedness, injunction, and optimization helps in establishing a framework for anticipatory decision-making. While dementia may offer a window of time to consider future decisions, individual beliefs about dementia including fears about stigma, loss of personhood, and solitude strongly impact anticipating sentiments. Concepts of anticipation can be useful for the examination of uncertainty, changing values, needs, and preferences interconnected with the dementia trajectory and can serve as a means to make an uncertain future more concrete. However, fears of losing one’s autonomy in the process of dementia also apply to possibilities of anticipation as these require cognitive assessment and reassessment of an imagined future with dementia.
