With a Z-score of 0.66 (74.5th percentile), this represents normal volume ; whole brain volume measures 983,748 mm³, 4.4% below the reference mean. With a Z-score of -0.58 (28.2th percentile), this represents normal volume . ",
  "text_data": "Age is 80.9 years. Gender is Male. Education: 18 years. MMSE: 25.0. APOEε4 alleles: 0.0. ",

  "gpt_diagnosis": "Reasoning: The ventricular volume is slightly above the reference mean but still within normal range (Z-score 0.66), while whole brain volume is slightly below the reference mean but also within normal range (Z-score -0.58). The MMSE score of 25 is borderline but does not strongly indicate cognitive impairment, and the absence of APOE4 reduces genetic risk.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to borderline MMSE but otherwise normal imaging and genetic profile)",
