  "text_data": "Age is 70.4 years. Gender is Female. Education: 18 years. MMSE: 29.0. MoCA: 25.0. Logical Memory: 12.0. APOEε4 alleles: 1.0. Biomarker levels: Florbetapir (AV45): 1.11 SUVR (normal ). ",
  "true_diagnosis": "Diagnosis: CN.",
  "gpt_diagnosis": "Reasoning: The hippocampal volume is slightly below the reference mean but still within the normal range (Z-score -0.92). Cognitive scores (MMSE 29, MoCA 25) are borderline for MCI but not strongly indicative of dementia. APOE4 carrier status and normal AV45 (amyloid PET) suggest lower Alzheimer's risk.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (MoCA is slightly low, but other markers are reassuring)",
