  "img_finding": "Image findings: ventricular volume measures 89,920 mm³, 91.3% above the reference mean. With a Z-score of 2.65 (99.6th percentile), this represents significant enlargement; whole brain volume measures 815,746 mm³, 20.7% below the reference mean. With a Z-score of -2.72 (0.3th percentile), this represents significant atrophy. ",
  "text_data": "Age is 87.1 years. Gender is Male. Education: 20 years. MMSE: 22.0. APOEε4 alleles: 1.0. ",
  "true_diagnosis": "Diagnosis: AD.",
  "gpt_diagnosis": "Reasoning: The data shows significant ventricular enlargement and whole brain atrophy, both with extreme Z-scores, indicating substantial structural brain changes. The MMSE score of 22.0 suggests cognitive impairment, and the presence of one APOE4 allele increases Alzheimer's risk.  \nDiagnosis: Dementia  \nConfidence: High",
