  "text_data": "Age is 83.2 years. Gender is Male. Education: 20 years. MMSE: 30.0. MoCA: 25.0. Logical Memory: 18.0. APOEε4 alleles: 0.0. Biomarker levels: Florbetapir (AV45): 1.07 SUVR (normal ). ",
  "true_diagnosis": "Diagnosis: CN.",
  "gpt_diagnosis": "Reasoning: The patient has a normal MMSE score (30/30) and a slightly reduced MoCA score (25/30), which is common in older adults due to factors like age-related cognitive changes or mild attentional/executive difficulties. The absence of APOE4 alleles and normal AV45 (amyloid PET) further suggests no significant Alzheimer's pathology.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (MoCA is borderline, but other markers are reassuring)",
