With a Z-score of -1.15 (12.5th percentile), this represents mild atrophy; hippocampal volume measures 7,417 mm³, 3.5% below the reference mean. With a Z-score of -0.39 (34.8th percentile), this represents normal volume ; whole brain volume measures 987,334 mm³, 4.1% below the reference mean. With a Z-score of -0.51 (30.6th percentile), this represents normal volume . ",
  "text_data": "Age is 62.6 years. Gender is Female. Education: 16 years. MMSE: 27.0. MoCA: 24.0. Logical Memory: 11.0. APOEε4 alleles: 1.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The ventricular volume shows mild atrophy, but hippocampal and whole brain volumes are within normal ranges. Cognitive scores (MMSE 27, MoCA 24) are slightly below optimal but not in the dementia range. APOE4 carrier status increases Alzheimer's risk but is not diagnostic alone.  \nDiagnosis: **MCI (Mild Cognitive Impairment)**  \nConfidence: **Medium** (cognitive scores suggest mild decline, but structural changes are not severe enough for dementia).",
