  "img_finding": "Image findings: ventricular volume measures 33,244 mm³, 29.3% below the reference mean. With a Z-score of -0.85 (19.7th percentile), this represents normal volume ; whole brain volume measures 942,660 mm³, 8.4% below the reference mean. With a Z-score of -1.10 (13.5th percentile), this represents mild atrophy. ",
  "text_data": "Age is 84.7 years. Gender is Male. Education: 16 years. MMSE: 30.0. APOEε4 alleles: 1.0. ",
  "true_diagnosis": "Diagnosis: CN.",
  "gpt_diagnosis": "Reasoning: The ventricular volume is within normal limits, while the whole brain volume shows mild atrophy, which can be age-related. The MMSE score of 30 is intact, and there are no cognitive complaints reported.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (mild atrophy could be early-stage but no cognitive impairment is present yet)",
