With a Z-score of -0.84 (20.1th percentile), this represents normal volume ; whole brain volume measures 888,830 mm³, 8.8% below the reference mean. With a Z-score of -1.11 (13.4th percentile), this represents mild atrophy. ",
  "text_data": "Age is 72.1 years. Gender is Female. Education: 19 years. MMSE: 28.0. Logical Memory: 13.0. Laboratory findings: Eosinophils: 2.59 (profound elevated); Neutrophils: 32.00 (profound reduced); Eosinophils: 34.80 (profound elevated). APOEε4 alleles: 0.0. ",

  "gpt_diagnosis": "Reasoning: The ventricular volume is within normal limits, while the whole brain volume shows mild atrophy. The MMSE score of 28 is within the normal range, and the absence of APOE4 reduces genetic risk.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium",
