  "img_finding": "Image findings: ventricular volume measures 63,306 mm³, 64.4% above the reference mean. With a Z-score of 1.54 (93.8th percentile), this represents moderate enlargement; whole brain volume measures 829,481 mm³, 23.2% below the reference mean. With a Z-score of -3.01 (0.1th percentile), this represents profound atrophy. ",
  "text_data": "Age is 79.1 years. Gender is Male. Education: 14 years. MMSE: 16.0. Logical Memory: 0.0. APOEε4 alleles: 1.0. ",
  "true_diagnosis": "Diagnosis: AD.",
  "gpt_diagnosis": "**Reasoning:** The data shows profound whole brain atrophy (Z-score -3.01, 0.1th percentile) and moderate ventricular enlargement (Z-score 1.54, 93.8th percentile), consistent with advanced neurodegeneration. The low MMSE score (16/30) and presence of an APOE4 allele further support significant cognitive impairment.  \n\n**Diagnosis:** **Dementia** (likely Alzheimer’s disease given APOE4 and atrophy pattern).  \n**Confidence:** **High** (severe atrophy, low MMSE, and APOE4 strongly align with dementia).",
