With a Z-score of 3.89 (100.0th percentile), this represents profound enlargement; whole brain volume measures 849,872 mm³, 6.6% below the reference mean. With a Z-score of -0.74 (23.1th percentile), this represents normal volume . ",
  "text_data": "Age is 91.1 years. Gender is Female. Education: 20 years. MMSE: 25.0. Logical Memory: 5.0. Laboratory findings: Vitamin B12: 939.00 (significant elevated); Eosinophils: 0.53 (profound elevated); Eosinophils: 8.00 (profound elevated); Cholesterol (High Performance): 272.00 (significant elevated).

  "gpt_diagnosis": "**Reasoning:** The ventricular volume is significantly enlarged (Z-score 3.89), suggesting substantial atrophy, while whole brain volume is within normal limits (Z-score -0.74). The MMSE score of 25 is borderline for mild cognitive impairment (MCI) but not definitive for dementia, especially given the advanced age.  \n\n**Diagnosis:** **MCI** (mild cognitive impairment)  \n**Confidence:** **Medium** (due to conflicting indicators—severe ventricular enlargement but preserved MMSE and no APOE4 risk)",
