With a Z-score of 0.89 (81.4th percentile), this represents normal volume ; whole brain volume measures 837,130 mm³, 18.7% below the reference mean. With a Z-score of -2.44 (0.7th percentile), this represents significant atrophy. ",
  "text_data": "Age is 85.8 years. Gender is Male. Education: 16 years. MMSE: 27.0. Logical Memory: 7.0. APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: AD.",
  "gpt_diagnosis": "Reasoning: The whole brain volume shows significant atrophy (Z-score -2.44, 0.7th percentile), which is concerning for neurodegeneration, but the MMSE score of 27 is within the normal range (≥26). The absence of APOE4 reduces genetic risk, but age is a strong non-modifiable risk factor.  \nDiagnosis: **MCI** (structural atrophy without clear cognitive impairment on MMSE)  \nConfidence: **Medium** (clinical correlation needed; MMSE may not capture subtle deficits)",
