  "text_data": "Age is 70.9 years. Gender is Female. Education: 18 years. MMSE: 26.0. Logical Memory: 0.0. APOEε4 alleles: 0.0. Biomarker levels: Amyloid beta: 485.50 pg/mL (mild reduced); Total tau: 440.70 pg/mL (significant elevated); Phosphorylated tau: 47.58 pg/mL (profound elevated). ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The MMSE score of 26 is within the normal range (typically 24-30), but the biomarker profile (mildly reduced Aβ, significantly elevated T-tau, and profoundly elevated P-tau) strongly suggests Alzheimer's pathology. The elevated tau markers, especially P-tau, are indicative of neurodegeneration despite the near-normal cognitive score.  \nDiagnosis: MCI (likely due to Alzheimer's pathology)  \nConfidence: Medium (MMSE is borderline, but biomarkers strongly support early Alzheimer's changes)",
