With a Z-score of 0.91 (81.9th percentile), this represents normal volume ; whole brain volume measures 1,097,520 mm³, 1.7% above the reference mean. With a Z-score of 0.22 (58.6th percentile), this represents normal volume . ",
  "text_data": "Age is 75.4 years. Gender is Male. Education: 12 years. MMSE: 23.0. Logical Memory: 0.0. APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "**Reasoning:** The ventricular volume is slightly elevated but still within the normal range (Z-score 0.91), and whole brain volume is normal (Z-score 0.22). The MMSE score of 23 suggests mild cognitive impairment, but the absence of APOE4 reduces genetic risk for Alzheimer's.  \n**Diagnosis:** MCI (Mild Cognitive Impairment)  \n**Confidence:** Medium (due to borderline MMSE but normal imaging and no APOE4 risk)",
