She identifies the main diagnostic biomarkers associated with dementia as genes (such as ApoE4), Amyloid and Tau proteins (present in, for example, cerebrospinal fluid, as well as plaques and tangles in the brain) and brain atrophy, visible on the new generation of MRI and PET scans (Leibing 2016, 46). The gene discussed is MAPT; the disease is dementia.
