  "text_data": "Age is 71.6 years. Gender is Female. Education: 14 years. MMSE: 17.0. MoCA: 5.0. Logical Memory: 0.0. APOEε4 alleles: 2.0. Biomarker levels: Florbetapir (AV45): 1.18 SUVR (normal ). ",
  "true_diagnosis": "Diagnosis: AD.",
  "gpt_diagnosis": "Reasoning: The patient shows significant cognitive impairment with MMSE and MoCA scores well below normal ranges (MMSE <24, MoCA <26), suggesting severe cognitive deficits. The presence of two APOE4 alleles increases Alzheimer's risk, but AV45 (amyloid PET) being normal is atypical for AD.  \nDiagnosis: Dementia (likely non-Alzheimer's subtype, e.g., vascular or frontotemporal)  \nConfidence: Medium (due to conflicting biomarkers—low amyloid but high genetic risk and severe impairment)",
