With a Z-score of -0.82 (20.7th percentile), this represents normal volume ; whole brain volume measures 1,002,580 mm³, 7.1% below the reference mean. With a Z-score of -0.92 (17.8th percentile), this represents normal volume . ",
  "text_data": "Age is 74.4 years. Gender is Male. Education: 14 years. MMSE: 30.0. Logical Memory: 14.0. APOEε4 alleles: 1.0. Biomarker levels: Pittsburgh compound B: 2.06 SUVR (mild elevated). ",

  "gpt_diagnosis": "Reasoning: The brain volumes (ventricular and whole brain) are within normal ranges, and the MMSE score of 30 is optimal, indicating no significant cognitive impairment. The presence of one APOE4 allele increases Alzheimer's risk but does not currently manifest as cognitive decline.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
