  "text_data": "Age is 86.7 years. Gender is Male. Education: 20 years. Handedness: Unknown. Race: Unknown. MMSE: 29.0. Logical Memory: 13.0. APOEε4 alleles: 0.0. Biomarker levels: Amyloid beta: 1610.00 pg/mL (moderate elevated); Total tau: 205.20 pg/mL (normal ); Phosphorylated tau: 19.87 pg/mL (normal ). ",
  "true_diagnosis": "Diagnosis: CN.",
  "gpt_diagnosis": "Reasoning: The MMSE score of 29 is within the normal range, and while Aβ is moderately elevated, T-tau and P-tau are normal, suggesting no significant neurodegeneration. The absence of APOE4 also reduces Alzheimer's risk.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (Aβ elevation warrants monitoring but current cognitive and biomarker profile does not suggest MCI or dementia).",
