  "img_finding": "Image findings: ventricular volume measures 53,467 mm³, 13.7% above the reference mean. With a Z-score of 0.40 (65.5th percentile), this represents normal volume ; whole brain volume measures 837,812 mm³, 18.6% below the reference mean. With a Z-score of -2.44 (0.7th percentile), this represents significant atrophy. ",
  "text_data": "Age is 86.2 years. Gender is Male. Education: 16 years. MMSE: 29.0. Logical Memory: 0.0. 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 29 is within the normal range, and there is no APOE4 risk allele. The ventricular volume is normal.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium  \n\n(While the brain atrophy is severe, the preserved cognitive function and lack of genetic risk suggest resilience or a very early stage of decline not yet clinically apparent. Further monitoring is warranted.)",
