  "img_finding": "Image findings: ventricular volume measures 71,614 mm³, 52.3% above the reference mean. With a Z-score of 1.52 (93.6th percentile), this represents moderate enlargement; whole brain volume measures 890,281 mm³, 13.5% below the reference mean. With a Z-score of -1.77 (3.9th percentile), this represents moderate atrophy. ",
  "text_data": "Age is 80.7 years. Gender is Male. Education: 14 years. MMSE: 28.0. Logical Memory: 2.0. APOEε4 alleles: 2.0. ",
  "true_diagnosis": "Diagnosis: AD.",
  "gpt_diagnosis": "Reasoning: The data shows moderate ventricular enlargement and moderate whole brain atrophy, which are structural changes often associated with neurodegenerative processes. Despite these changes, the MMSE score of 28.0 is within the normal range (≥26), suggesting preserved cognitive function.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to conflicting imaging and cognitive findings; APOE4 homozygosity increases AD risk but does not confirm impairment)",
