  "img_finding": "Image findings: ventricular volume measures 23,473 mm³, 36.5% below the reference mean. With a Z-score of -0.99 (16.2th percentile), this represents normal volume ; whole brain volume measures 1,031,450 mm³, 11.1% above the reference mean. With a Z-score of 1.34 (90.9th percentile), this represents mild enlargement. ",
  "text_data": "Age is 81.0 years. Gender is Female. Education: 19 years. MMSE: 19.0. Logical Memory: 0.0. APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: AD.",
  "gpt_diagnosis": "**Reasoning:** The MMSE score of 19 suggests cognitive impairment, but the brain volume measurements (ventricular volume normal, whole brain volume mildly enlarged) do not strongly support neurodegeneration. The absence of APOE4 reduces genetic risk for Alzheimer’s, but the MMSE is concerning.  \n**Diagnosis:** MCI (Mild Cognitive Impairment)  \n**Confidence:** Medium (cognitive impairment is present, but structural findings are not strongly indicative of dementia).",
