Few fields of medicine are as polarised as that of Alzheimer’s disease and dementia research. The debate has even taken on religious undertones, with supporters of the amyloid cascade hypothesis of Alzheimer’s disease being called baptists, and critics of this theory being called tauists (from tau, the other most probable candidate in the pathogenesis of Alzheimer’s disease).1 Although disagreement is a sign of healthy scientific debate, the radicalisation of positions prevents honest and transparent self-criticism and, ultimately, the development of meaningful responses to patients’ needs.
