With a Z-score of -1.21 (11.2th percentile), this represents mild atrophy; whole brain volume measures 992,440 mm³, 3.6% below the reference mean. With a Z-score of -0.47 (32.0th percentile), this represents normal volume . ",
  "text_data": "Age is 80.2 years. Gender is Male. Education: 16 years. MMSE: 28.0. Logical Memory: 0.0. APOEε4 alleles: 2.0. ",

  "gpt_diagnosis": "Reasoning: The ventricular volume shows mild atrophy (Z-score -1.21), but whole brain volume is within normal limits (Z-score -0.47). The MMSE score of 28 is normal, and while APOE4 homozygosity (2.0) is a strong genetic risk factor, there are no significant cognitive deficits currently.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to conflicting atrophy and genetic risk vs. normal cognition and brain volume)",
