  "text_data": "Age is 82.9 years. Gender is Male. Education: 12 years. MMSE: 27.0. Logical Memory: 0.0. APOEε4 alleles: 1.0. Biomarker levels: Amyloid beta: 570.20 pg/mL (mild reduced); Total tau: 188.50 pg/mL (normal ); Phosphorylated tau: 15.80 pg/mL (normal ). ",

  "gpt_diagnosis": "Reasoning: The MMSE score of 27 is within the normal range (typically 24-30), and the biomarkers (Aβ mildly reduced, T-tau and P-tau normal) do not strongly indicate Alzheimer's pathology. However, the presence of one APOE4 allele and mildly reduced Aβ may suggest early preclinical changes.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to mildly reduced Aβ and APOE4 status, but normal cognition and tau levels)",
