With a Z-score of 0.32 (62.4th percentile), this represents normal volume ; hippocampal volume measures 6,781 mm³, 2.7% below the reference mean. With a Z-score of -0.23 (40.8th percentile), this represents normal volume ; whole brain volume measures 1,034,700 mm³, 0.5% above the reference mean. With a Z-score of 0.07 (52.8th percentile), this represents normal volume . ",
  "text_data": "Age is 80.8 years. Gender is Male. Education: 16 years. MMSE: 30.0. MoCA: 25.0. Logical Memory: 3.0. Laboratory findings: Eosinophils: 0.47 (profound elevated); Eosinophils: 10.60 (profound elevated); GGT: 102.00 (profound elevated); Phosphorus: 2.40 (significant reduced). APOEε4 alleles: 0.0. ",

  "gpt_diagnosis": "Reasoning: The brain volumes (ventricular, hippocampal, and whole brain) are within normal ranges, with only a slight hippocampal reduction (-2.7%). The MMSE score of 30 is normal, but the MoCA score of 25 suggests mild cognitive impairment (MCI). The absence of APOE4 reduces genetic risk.  \nDiagnosis: **MCI**  \nConfidence: **Medium** (MoCA indicates possible MCI, but structural imaging is normal and MMSE is intact)",
