  "img_finding": "Image findings: hippocampal volume measures 6,099 mm³, 19.3% below the reference mean. With a Z-score of -1.88 (3.0th percentile), this represents moderate atrophy. ",
  "text_data": "Age is 75.5 years. Gender is Male. Education: 20 years. MMSE: 22.0. MoCA: 15.0. Logical Memory: 2.0. APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: AD.",
  "gpt_diagnosis": "**Reasoning:** The hippocampal volume shows moderate atrophy (Z-score -1.88, 3rd percentile), which is concerning for neurodegeneration. The cognitive scores (MMSE 22, MoCA 15) are below normal ranges, suggesting significant cognitive impairment.  \n\n**Diagnosis:** **Dementia** (likely Alzheimer’s disease given hippocampal atrophy, though APOE4-negative status slightly reduces certainty).  \n\n**Confidence:** **Medium** (clear cognitive decline and hippocampal atrophy, but lack of APOE4 and other biomarker data limits full certainty).",
