Biomarker levels: Florbetapir (AV45): 1.69 SUVR (profound elevated); Amyloid beta: 793.30 pg/mL (normal ); Total tau: 380.20 pg/mL (moderate elevated); Phosphorylated tau: 42.58 pg/mL (significant elevated). ",
  "true_diagnosis": "Diagnosis: CN.",
  "gpt_diagnosis": "Reasoning: The MMSE score of 27 is within the normal range, but the MoCA score of 22 suggests mild cognitive impairment (MCI). Biomarkers show significant elevation in P-tau and profound elevation in AV45 (amyloid PET), indicating Alzheimer's pathology, despite normal Aβ levels (likely due to assay variability or clearance issues). Elevated T-tau and P-tau further support neurodegenerative changes.  \nDiagnosis: MCI (likely due to Alzheimer's pathology)  \nConfidence: Medium (clinical scores conflict slightly, but biomarkers strongly suggest early Alzheimer's progression)",
