  "text_data": "Age is 78.6 years. Gender is Female. Education: 12 years. MMSE: 14.0. Logical Memory: 2.0. APOEε4 alleles: 0.0. Biomarker levels: Florbetapir (AV45): 1.30 SUVR (moderate elevated). ",
  "true_diagnosis": "Diagnosis: AD.",
  "gpt_diagnosis": "Reasoning: The MMSE score of 14 indicates significant cognitive impairment, and the moderate elevation in AV45 (amyloid PET) suggests amyloid pathology. The absence of APOE4 does not rule out Alzheimer's, as amyloid burden is already evident.  \nDiagnosis: Dementia (likely Alzheimer’s disease)  \nConfidence: Medium (clinical and biomarker data align, but additional neuropsychological testing or CSF biomarkers could strengthen certainty).",
