  "img_finding": "Image findings: ventricular volume measures 52,610 mm³, 11.9% above the reference mean. With a Z-score of 0.35 (63.5th percentile), this represents normal volume ; whole brain volume measures 986,391 mm³, 4.2% below the reference mean. With a Z-score of -0.54 (29.3th percentile), this represents normal volume . ",
  "text_data": "Age is 81.2 years. Gender is Male. Education: 16 years. MMSE: 26.0. Logical Memory: 3.0. Laboratory findings: Serum Glucose: 151.00 (profound elevated); Albumin: 4.70 (significant elevated); Calcium (EDTA): 10.70 (significant elevated); Triglycerides (GPO): 362.00 (profound elevated); Serum Uric Acid: 9.60 (significant elevated). APOEε4 alleles: 0.0. Biomarker levels: Total tau: 313.00 pg/mL (normal ); Phosphorylated tau: 24.68 pg/mL (normal ). ",

  "gpt_diagnosis": "Reasoning: The brain volumes (ventricular and whole brain) are within normal ranges, and biomarkers (T-tau, P-tau) are normal. The MMSE score of 26 is slightly below the typical cutoff of 27 but is not strongly indicative of cognitive impairment in isolation.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to borderline MMSE but normal biomarkers and imaging)",
