With a Z-score of 0.31 (62.0th percentile), this represents normal volume ; hippocampal volume measures 5,919 mm³, 8.9% below the reference mean. With a Z-score of -0.71 (23.9th percentile), this represents normal volume ; whole brain volume measures 974,528 mm³, 5.0% above the reference mean. With a Z-score of 0.60 (72.5th percentile), this represents normal volume . ",
  "text_data": "Age is 80.4 years. Gender is Female. Education: 17 years. MMSE: 29.0. MoCA: 24.0. Logical Memory: 12.0. APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "**Reasoning:** The hippocampal volume is slightly reduced (8.9% below mean, Z-score -0.71), but still within the normal range. MMSE is normal (29/30), but MoCA (24/30) suggests mild cognitive impairment (MCI), particularly given the borderline score. No APOE4 allele reduces Alzheimer's risk.  \n**Diagnosis:** MCI  \n**Confidence:** Medium (MoCA suggests MCI, but structural changes are mild and cognitive scores are mixed)",
