From: Peter Whitehouse. The Diagnosis and Treatment of Alzheimerās: Are We Being (Ir)Responsible?, pp. 21ā29
Within a given society, who gains power to try to assist people trying to improve their memory depends on concepts of how body and brain relate to each other and what the respective roles of healers and educators (e.g. shamans, psychiatrists, neurologists, school teachers, parents etc.) are. In twenty-first-century Western culture, diet, general health, cognitive activity, education, income, and social relations have all been tied to ābrain healthā and clinical conditions, such as dementia (George et al. 2013). In this chapter, I call for a radical re-examination of the factual and value issues surrounding this critical issue of our timesācognitive and behavioural ageingāin the context of the other complex challenges of our modern world. ā¦ I set the stage for a consideration of responsible research, innovation, planning, and use of resources in addressing dementia and brain health, including discussing linguistically contested concepts, such as āAlzheimerās disease (AD)ā and āmild cognitive impairment (MCI)ā. I will examine shifts over time in perspectives about both diagnosis and therapeutics ā¦.
The current state of Alzheimerās is one of quite widespread dissatisfaction with available diagnostic and therapeutic approaches from patients, families, physicians, and policymakers. A shift in emphasis from systems to molecular neuroscience occurred as genetic mutations in early-onset AD pointed to problems in amyloid-related proteins that are associated with neurotic or senile plaque ā¦.
The genetic revolution in medicine influenced the dementia field to raise their expectations for more powerful therapies based on understanding cause and pathogenesis. There are, however, significant challenges to this attempt to develop molecular and genetic diagnostics and therapeutics. Alzheimerās is heterogeneous at any level at which it is examinedāgenetic, pathological, neurochemical, or clinical (Whitehouse and George 2008). Several hundred causative genetic mutations and a few risk-modifying genes have been described in different patient populations. The relative distribution of cell loss and pathological features can vary across different individuals. It is a truism in the field that: āonce you have seen one patient with Alzheimerās youāve seen one patient with Alzheimerāsā.
So where are we today? Some peopleāperhaps the majority of researchers and their advocatesāthink that the march to progress continues even at a slower pace. For them, the model and hope of the future is more money, leading to more hypotheses, panels of biomarkers, bigger data sets, more efficient drug development (through less regulation and centralized, and perhaps, relaxed ethical review), and ultimately, a cocktail of therapies. Yet, many studies are not even replicated in the lab and the hope is found to be false. ā¦ Just as we are culturally reinventing ageing to be viewed as a time of opportunity, not just loss, Alzheimerās remains the elephant in the room, causing fear and mental blocks. That said, an alternative, more geriatric, public health, social science, and arts/humanities-based perspective about dementia is emerging. The social sciences, such as anthropology, can provide new critical perspectives (Whitehouse et al. 2005). In this view, dysfunction and disability are more important than precise diagnosis; quality of life trumps cognitive enhancement; community engagement is key; and population health perspectives gain influence over individual health (Whitehouse 2010).
Behind the standard view of AD and the dominant ways of presenting this perspective to the public lies much irresponsibility. The concept of Alzheimerās has changed over time, is changing now, and perhaps, even needs elimination or significant revision. ā¦ Does being irresponsible increase the costs of missed opportunities, such as investment of resources else-where in a non-medical way (Katz and Meller 2014; Whitehouse 2010; Portacolone et al. 2014)? ā¦ I have argued here that at least some behaviours in the Alzheimerās field are irresponsible. Individual scientists who self-promote, and, for example, publish studies in animals that claim dramatic implications for human disease (i.e. breakthroughs) are individually irresponsible. They raise false expectations and hope and drive resources in inappropriate directions to irresponsible actors ā¦.
Efforts to improve the quality of life of people with cognitive impairment and their care partners are undergoing dramatic transformation. Although some hope is held out for molecular reductionist, genetically based therapies, more evidence is emerging that psychosocial and public health measures may be more effective ā¦.
A deeper and broader understanding of dementia in the context of community-based brain health could lead to huge advances in the development of our human species and its ability to address the challenging future. Education and lifelong cognitive activities have consistently shown in population studies to be protective factors against getting dementia later in life. Intergenerational education may be one social innovation relevant to community brain health and resiliency. At The Intergenerational Schools in Cleveland, local elders, including those with dementia, contribute to their own brain vitality as well as the long-term brain health of children by serving as mentors in an elementary school (George and Whitehouse 2010). Moreover, dementia-friendly communities should be part of lifelong age-friendly communities for all of us. Attending to the cognitive harms of air and water pollution and income inequity could motivate us even further to address these global issues. Asking deeper, more critical questions about āAlzheimerāsā will expose profound challenges and dilemmas surrounding and embedded in the current role of science in society, the effects of commodification in healthcare, the nature of ageing, and, in fact, our very humanity. Addressing such more fundamental probing questions about our cultural beliefs and the distribution of power in our societies should also lead to more responsible innovations and actions.
