  "img_finding": "Image findings: ventricular volume measures 59,105 mm³, 59.9% above the reference mean. With a Z-score of 1.62 (94.7th percentile), this represents moderate enlargement; whole brain volume measures 850,683 mm³, 8.3% below the reference mean. With a Z-score of -1.00 (15.8th percentile), this represents mild atrophy. ",
  "text_data": "Age is 80.3 years. Gender is Female. Education: 12 years. Handedness: Unknown. Race: Unknown. MMSE: 22.0. Logical Memory: 0.0. APOEε4 alleles: 1.0. ",
  "true_diagnosis": "Diagnosis: AD.",
  "gpt_diagnosis": "Reasoning: The data shows moderate ventricular enlargement and mild whole brain atrophy, which are indicative of neurodegenerative changes. Combined with an MMSE score of 22 (suggesting cognitive impairment) and the presence of one APOE4 allele (a risk factor for Alzheimer's), this aligns with a dementia profile.  \nDiagnosis: Dementia  \nConfidence: Medium (clinical correlation and additional biomarkers would strengthen certainty).",
