Diagnostic Category | Biomarker Probability of AD Etiology | Aβ (PET or CSF) | Neuronal Injury (tau, FDG, sMRI) |
---|---|---|---|
MCI–criteria | ambiguous | conflicting, indeterminant or untested | conflicting, indeterminant or untested |
MCI due to AD - intermediate likelihood | Intermediate | positive | untested |
untested | positive | ||
MCI due to AD - high likelihood | High | positive | positive |
MCI due to AD - unlikely | Low | negative | negative |
AD: Alzheimer's disease; Aβ: amyloid beta peptide; PET: positron emission tomography; CSF: cerebrospinal fluid; FDG: fluorodeoxyglucose; sMRI: structural magnetic resonance imaging.
