With a Z-score of 8.83 (100.0th percentile), this represents profound enlargement; whole brain volume measures 966,584 mm³, 3.5% below the reference mean. With a Z-score of -0.60 (27.5th percentile), this represents normal volume . ",
  "text_data": "Age is 92.4 years. Gender is Male. Education: 20 years. MMSE: 26.0. MoCA: 22.0. Logical Memory: 7.0. APOEε4 alleles: 0.0. ",

  "gpt_diagnosis": "Reasoning: The ventricular volume is significantly enlarged (Z-score 8.83), indicating substantial atrophy, while whole brain volume is within normal limits (Z-score -0.60). Cognitive scores (MMSE 26, MoCA 22) are borderline but not severely impaired, suggesting possible MCI rather than dementia.  \nDiagnosis: MCI  \nConfidence: Medium",
