With a Z-score of 1.09 (86.3th percentile), this represents mild enlargement; hippocampal volume measures 7,267 mm³, 3.9% below the reference mean. With a Z-score of -0.38 (35.3th percentile), this represents normal volume ; whole brain volume measures 1,108,520 mm³, 2.7% above the reference mean. With a Z-score of 0.35 (63.7th percentile), this represents normal volume . ",
  "text_data": "Age is 72.0 years. Gender is Male. Education: 13 years. MMSE: 28.0. MoCA: 22.0. APOEε4 alleles: 2.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The ventricular volume is mildly enlarged (45.6% above reference mean), but hippocampal and whole brain volumes are within normal ranges. The MMSE score (28/30) is normal, but the MoCA (22/30) suggests mild cognitive impairment (MCI). The presence of two APOE4 alleles increases Alzheimer's risk.  \nDiagnosis: **MCI**  \nConfidence: **Medium** (MoCA indicates MCI, but MMSE is normal, and structural changes are mild)",
