Within the current diagnostic criteria for Alzheimer’s disease (AD), biomarkers of neuronal degeneration are treated equally. This study quantifies the degree of agreement among the biomarkers: regional cerebral hypometabolism on FDG- PET, hippocampal atrophy on MRI, and increased levels of p-tau181 in CSF. Data of 585 patients from ADNI were analyzed: healthy individuals, patients with MCI, and with probable AD dementia. The overall chance-corrected agreement among the biomarkers is poor with a high percentage of conflicting biomarkers. The degree of agreement is higher in individuals with abnormal CSF Amyloid beta (1-42).
