Amyloid- β PET Classification on Cognitive Aging Stages Using the Centiloid Scale

ConclusionSuperAgers exhibited a similar A β load to AC and MC, differing in cognitive performance. Independently of cut-point used (10 CL, 19 CL, or 30 CL), three SA individuals were classified as Aβ positive, showing the duality between the individual’s clinics and the biological definition of Alzheimer’s. Different cut-points lead t o Aβ positivity classification mismatch in individuals, and an extra care is needed for individuals who have a CL value between 10 and 30 CL.
