  "text_data": "Age is 76.1 years. Gender is Male. Education: 12 years. MMSE: 27.0. Logical Memory: 2.0. APOEε4 alleles: 1.0. Biomarker levels: Amyloid beta: 527.80 pg/mL (mild reduced); Total tau: 376.40 pg/mL (moderate elevated); Phosphorylated tau: 34.85 pg/mL (moderate elevated). ",

  "gpt_diagnosis": "Reasoning: The MMSE score of 27 is within the normal range (typically 24-30), but the presence of moderately elevated T-tau and P-tau, along with mildly reduced Aβ, suggests early neurodegenerative changes consistent with Alzheimer's pathology. The APOE4 allele further increases the risk.  \nDiagnosis: MCI (Mild Cognitive Impairment)  \nConfidence: Medium (MMSE is normal, but biomarkers strongly suggest early Alzheimer's pathology)",
