With a Z-score of 2.81 (99.8th percentile), this represents significant enlargement; whole brain volume measures 1,121,980 mm³, 9.0% above the reference mean. With a Z-score of 1.18 (88.1th percentile), this represents mild enlargement. ",
  "text_data": "Age is 83.0 years. Gender is Male. Education: 16 years. MMSE: 29.0. MoCA: 24.0. Logical Memory: 11.0. APOEε4 alleles: 1.0. ",

  "gpt_diagnosis": "**Reasoning:** The ventricular volume is significantly enlarged (Z-score 2.81, 99.8th percentile), which is a strong indicator of neurodegeneration, while whole brain volume is only mildly enlarged (Z-score 1.18). Despite high MMSE (29), the MoCA (24) suggests subtle cognitive deficits, consistent with early cognitive decline. APOE4 carrier status increases Alzheimer's risk.  \n\n**Diagnosis:** **Mild Cognitive Impairment (MCI)**  \n**Confidence:** **Medium** (due to conflicting MMSE/MoCA scores but strong structural evidence of neurodegeneration)",
