  "text_data": "Age is 83.8 years. Gender is Female. Education: 16 years. MMSE: 26.0. MoCA: 21.0. Logical Memory: 1.0. APOEε4 alleles: 1.0. Biomarker levels: Florbetapir (AV45): 1.46 SUVR (significant elevated). ",
  "true_diagnosis": "Diagnosis: AD.",
  "gpt_diagnosis": "Reasoning: The patient shows mild cognitive impairment based on MoCA score (21/30), which is below the typical cutoff for normal cognition (≥26). The MMSE score (26/30) is borderline, but the elevated AV45 (amyloid PET) and presence of an APOE4 allele suggest underlying Alzheimer's pathology.  \nDiagnosis: MCI  \nConfidence: Medium (due to borderline MMSE but supportive biomarker evidence)",
