  "text_data": "Age is 89.8 years. Gender is Female. Education: 13 years. MMSE: 27.0. MoCA: 21.0. Logical Memory: 3.0. APOEε4 alleles: 0.0. Biomarker levels: Florbetapir (AV45): 1.49 SUVR (profound elevated). ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The MMSE score of 27 is within the normal range (≥26), but the MoCA score of 21 suggests mild cognitive impairment (MCI) as it falls below the typical cutoff of 26. The profound elevation in AV45 (amyloid PET) indicates significant amyloid deposition, which is strongly associated with Alzheimer's pathology. The absence of APOE4 does not rule out Alzheimer's, especially given the amyloid burden.  \n\nDiagnosis: MCI (likely due to Alzheimer's pathology)  \nConfidence: Medium (due to discrepancy between MMSE and MoCA, but strong amyloid evidence supports underlying Alzheimer's changes)",
