Fabricating mice and dementia: opening up relations in multi-species research

Abstract

In this chapter we use recent stories of scientific breakthrough around the amyloid cascade hypothesis (ACH) to frame our exploration of the organisation of translational research on dementia using mouse models of Alzheimer’s disease. Telling a story of success about the ACH today has involved narrowing down the ways that people, animals and drug pathways are brought together by focusing on the specific biological processes that can be modelled, evidenced and altered in multi-species experimental systems. We then explore how people affected by dementia, acting as patient representatives in reviewing applications for new biomedical research, locate themselves and their families within these stories of recurrent hope and delayed promise. We conclude by reflecting on the different dimensions of accountability in dementia research and the challenge of working across multi-species relations and the multiple versions of dementia. We suggest the processes of fabrication described here may be usefully applied to understand the complex histories of animal models of dementia and open up opportunities for multidisciplinary research able to articulate the multiplicity of dementia with multi-species dementia.
