  "text_data": "Age is 76.5 years. Gender is Female. Education: 20 years. MMSE: 29.0. Logical Memory: 19.0. APOEε4 alleles: 0.0. Biomarker levels: Amyloid beta: 403.20 pg/mL (moderate reduced); Total tau: 237.50 pg/mL (normal ); Phosphorylated tau: 22.36 pg/mL (normal ). ",
  "true_diagnosis": "Diagnosis: CN.",
  "gpt_diagnosis": "Reasoning: The MMSE score of 29 is within the normal range, indicating no significant cognitive impairment. However, the moderate reduction in Aβ suggests early amyloid pathology, but normal T-tau and P-tau levels argue against significant neurodegeneration.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to conflicting Aβ and tau markers despite normal cognition)",
