With a Z-score of 1.37 (91.5th percentile), this represents mild enlargement; whole brain volume measures 849,398 mm³, 17.5% below the reference mean. With a Z-score of -2.29 (1.1th percentile), this represents significant atrophy. ",
  "text_data": "Age is 83.1 years. Gender is Male. Education: 17 years. MMSE: 30.0. MoCA: 24.0. Logical Memory: 12.0. APOEε4 alleles: 0.0. ",

  "gpt_diagnosis": "**Reasoning:** The data shows significant whole brain atrophy (Z-score -2.29, 1.1th percentile) and mild ventricular enlargement, which are structural changes often associated with neurodegeneration. Despite a normal MMSE (30.0), the MoCA score (24.0) suggests mild cognitive impairment, and the absence of APOE4 does not rule out dementia.  \n\n**Diagnosis:** **MCI** (mild cognitive impairment)  \n**Confidence:** **Medium** (due to conflicting MMSE/MoCA scores but clear structural atrophy)",
