  "text_data": "Age is 76.0 years. Gender is Male. Education: 18 years. MMSE: 26.0. MoCA: 20.0. Logical Memory: 0.0. APOEε4 alleles: 1.0. Biomarker levels: Florbetapir (AV45): 1.47 SUVR (profound elevated). ",
  "true_diagnosis": "Diagnosis: AD.",
  "gpt_diagnosis": "Reasoning: The MMSE score of 26 is within the normal range (typically 24-30), but the MoCA score of 20 suggests mild cognitive impairment (MCI) as it falls below the typical cutoff of 26. The presence of one APOE4 allele and profoundly elevated AV45 (amyloid PET) indicates significant amyloid pathology, which is often associated with Alzheimer's disease. The combination of cognitive test results and biomarker evidence suggests progression toward dementia.  \n\nDiagnosis: Dementia (likely Alzheimer's disease)  \nConfidence: Medium (clinical scores are borderline, but biomarker evidence strongly supports neurodegenerative disease)",
