With a Z-score of -0.56 (28.7th percentile), this represents normal volume ; whole brain volume measures 968,982 mm³, 10.2% below the reference mean. With a Z-score of -1.33 (9.2th percentile), this represents mild atrophy. ",
  "text_data": "Age is 75.0 years. Gender is Male. Education: 12 years. MMSE: 29.0. Laboratory findings: Total Protein: 6.10 (significant reduced); Albumin: 3.30 (significant reduced); Calcium (EDTA): 8.90 (significant reduced); AST (SGOT): 14.00 (significant reduced); Phosphorus: 2.60 (significant reduced). APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: CN.",
  "gpt_diagnosis": "Reasoning: The ventricular volume is within normal limits, but there is mild whole brain atrophy (Z-score -1.33, 9.2th percentile). However, cognitive function (MMSE 29/30) is intact, and there is no APOE4 genetic risk factor.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (mild atrophy could precede clinical symptoms, but current cognitive performance is normal)",
