With a Z-score of 0.64 (73.9th percentile), this represents normal volume ; whole brain volume measures 1,101,530 mm³, 2.1% above the reference mean. With a Z-score of 0.27 (60.5th percentile), this represents normal volume . ",
  "text_data": "Age is 74.4 years. Gender is Male. Education: 12 years. MMSE: 27.0. Logical Memory: 0.0. APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "**Reasoning:** The ventricular volume and whole brain volume are within normal ranges (Z-scores close to 0, percentiles near 50th). The MMSE score of 27 is within the normal range (≥26), and the absence of APOE4 reduces genetic risk. No significant structural or cognitive deficits are evident.  \n\n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
