  "text_data": "Age is 81.0 years. Gender is Female. Education: 18 years. MMSE: 24.0. MoCA: 22.0. Logical Memory: 0.0. APOEε4 alleles: 0.0. Biomarker levels: Florbetapir (AV45): 1.54 SUVR (profound elevated); Amyloid beta: 714.70 pg/mL (normal ); Total tau: 282.80 pg/mL (normal ); Phosphorylated tau: 22.79 pg/mL (normal ). ",
  "true_diagnosis": "Diagnosis: AD.",
  "gpt_diagnosis": "Reasoning: The patient shows normal Aβ, T-tau, and P-tau levels, but AV45 (amyloid PET) is profoundly elevated, suggesting significant amyloid deposition despite normal CSF biomarkers. MMSE (24) and MoCA (22) scores indicate mild cognitive impairment, but not severe dementia.  \nDiagnosis: MCI  \nConfidence: Medium  \n\n(Note: The discrepancy between normal CSF biomarkers and elevated AV45 is unusual and may warrant further investigation. The cognitive scores align with MCI, but the amyloid burden raises questions about early AD pathology.)",
