  "img_finding": "Image findings: ventricular volume measures 45,458 mm³, 9.3% above the reference mean. With a Z-score of 1.46 (92.8th percentile), this represents mild enlargement; whole brain volume measures 800,522 mm³, 12.0% below the reference mean. With a Z-score of -1.34 (9.0th percentile), this represents mild atrophy. ",
  "text_data": "Age is 93.6 years. Gender is Female. Education: 20 years. Handedness: Right. Race: White. Medical history: Head, Eyes, Ears, Nose and Throat; Cardiovascular; Musculoskeletal; Endocrine-Metabolic. MMSE: 30.0. MoCA: 26.0. Logical Memory: 17.0. APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: CN.",
  "gpt_diagnosis": "Reasoning: The patient shows mild ventricular enlargement and mild whole brain atrophy, which could suggest early neurodegenerative changes. However, cognitive scores (MMSE 30, MoCA 26) are within normal limits for age, and there is no APOE4 risk allele present.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (imaging changes are mild and not yet clinically significant, but age-related changes cannot be ruled out)",
