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
MCI due to AD - intermediate likelihood	Intermediate	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.
