  "text_data": "Age is 80.5 years. Gender is Female. Education: 18 years. MMSE: 18.0. MoCA: 11.0. Logical Memory: 0.0. APOEε4 alleles: 1.0. Biomarker levels: Amyloid beta: 585.40 pg/mL (mild reduced); Total tau: 317.80 pg/mL (normal ); Phosphorylated tau: 28.25 pg/mL (normal ). ",
  "true_diagnosis": "Diagnosis: AD.",
  "gpt_diagnosis": "Reasoning: The patient shows significant cognitive impairment (MMSE 18, MoCA 11) with mild amyloid reduction (Aβ) but normal tau levels, suggesting Alzheimer's pathology without significant neurodegeneration. The low MMSE and MoCA scores are consistent with dementia rather than MCI.  \nDiagnosis: Dementia (likely Alzheimer's disease)  \nConfidence: Medium (clinical scores strongly suggest dementia, but biomarker profile is not fully conclusive for AD)",
