With a Z-score of -0.38 (35.1th percentile), this represents normal volume ; whole brain volume measures 978,838 mm³, 9.3% below the reference mean. With a Z-score of -1.21 (11.3th percentile), this represents mild atrophy. ",
  "text_data": "Age is 78.1 years. Gender is Male. Education: 17 years. MMSE: 26.0. Logical Memory: 0.0. Laboratory findings: Basophils: 1.40 (significant elevated); Creatine Kinase: 429.00 (profound elevated); ALT (SGPT): 48.00 (profound elevated); AST (SGOT): 56.00 (profound elevated).

  "gpt_diagnosis": "Reasoning: The patient shows mild whole brain atrophy (Z-score -1.21, 11.3th percentile) but normal ventricular volume. The MMSE score of 26 is borderline (normal range typically 24-30 for this age), and the presence of one APOE4 allele increases Alzheimer's risk.  \nDiagnosis: **MCI (Mild Cognitive Impairment)**  \nConfidence: **Medium** (MMSE is near the cutoff, and brain atrophy is mild but not severe enough for definitive dementia)",
