  "img_finding": "Image findings: hippocampal volume measures 6,822 mm³, 15.0% below the reference mean. With a Z-score of -1.50 (6.7th percentile), this represents moderate atrophy. ",
  "text_data": "Age is 62.1 years. Gender is Male. Education: 18 years. MMSE: 26.0. MoCA: 23.0. Logical Memory: 6.0. APOEε4 alleles: 2.0. ",
  "true_diagnosis": "Diagnosis: AD.",
  "gpt_diagnosis": "Reasoning: The hippocampal volume shows moderate atrophy (Z-score -1.5, 6.7th percentile), which is concerning for early neurodegeneration. The MMSE (26) and MoCA (23) scores suggest mild cognitive impairment, and the presence of two APOE4 alleles increases Alzheimer's risk.  \nDiagnosis: **MCI** (likely prodromal Alzheimer’s disease)  \nConfidence: **Medium** (clinical scores are borderline, but hippocampal atrophy and APOE4 status support MCI due to AD)",
