  "text_data": "Age is 86.1 years. Gender is Male. Education: 14 years. MMSE: 27.0. Logical Memory: 19.0. APOEε4 alleles: 0.0. Biomarker levels: Amyloid beta: 1554.00 pg/mL (mild elevated); Total tau: 229.30 pg/mL (normal ); Phosphorylated tau: 20.77 pg/mL (normal ). ",
  "true_diagnosis": "Diagnosis: CN.",
  "gpt_diagnosis": "Reasoning: The MMSE score of 27 is within the normal range (typically 24-30), and the APOE4 status is negative. While Aβ is mildly elevated, T-tau and P-tau are normal, suggesting minimal neurodegeneration.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (mild Aβ elevation raises some concern, but other markers and cognitive performance support normal cognition)",
