With a Z-score of 1.15 (87.6th percentile), this represents mild enlargement; whole brain volume measures 1,012,290 mm³, 3.9% above the reference mean. With a Z-score of 0.49 (68.7th percentile), this represents normal volume . ",
  "text_data": "Age is 73.9 years. Gender is Female. Education: 16 years. MMSE: 28.0. Logical Memory: 9.0. Laboratory findings: Vitamin B12: 1272.00 (profound elevated); Monocytes: 0.14 (significant reduced); WBC: 2.32 (significant reduced); Neutrophils: 1.30 (significant reduced); Lymphocytes: 0.77 (significant reduced); Total Bilirubin: 0.80 (significant elevated); Phosphorus: 2.60 (significant reduced).

  "gpt_diagnosis": "Reasoning: The ventricular volume is mildly enlarged (50.4% above reference mean, Z-score 1.15), which can indicate atrophy, but whole brain volume is normal (Z-score 0.49). MMSE score of 28 is within the normal range (≥26), and APOE4 heterozygous status is a risk factor but not diagnostic. No significant cognitive impairment is reported.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (ventricular enlargement raises some concern, but normal MMSE and brain volume support CN)",
