With a Z-score of -0.13 (44.9th percentile), this represents normal volume ; whole brain volume measures 967,460 mm³, 10.4% below the reference mean. With a Z-score of -1.35 (8.9th percentile), this represents mild atrophy. ",
  "text_data": "Age is 78.4 years. Gender is Male. Education: 13 years. MMSE: 29.0. APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The ventricular volume is within normal limits, but the whole brain volume shows mild atrophy (8.9th percentile). Despite this, the MMSE score of 29 is in the normal range, and there is no APOE4 genetic risk factor.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (mild atrophy could suggest early changes, but cognitive performance remains intact)",
