With a Z-score of -0.04 (48.3th percentile), this represents normal volume ; whole brain volume measures 1,088,320 mm³, 0.8% above the reference mean. With a Z-score of 0.11 (54.3th percentile), this represents normal volume . ",
  "text_data": "Age is 77.7 years. Gender is Male. Education: 19 years. MMSE: 30.0. MoCA: 22.0. APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "**Reasoning:** The hippocampal and whole brain volumes are within normal ranges, and the MMSE score of 30 indicates no significant cognitive impairment. However, the MoCA score of 22 suggests mild cognitive deficits, though APOE4 negativity reduces Alzheimer's risk.  \n**Diagnosis:** **MCI** (Mild Cognitive Impairment)  \n**Confidence:** **Medium** (due to discrepancy between MMSE and MoCA, but normal imaging and no genetic risk factors)",
