  "img_finding": "Image findings: hippocampal volume measures 4,399 mm³, 36.9% below the reference mean. With a Z-score of -3.19 (0.1th percentile), this represents profound atrophy. ",
  "text_data": "Age is 84.3 years. Gender is Male. Education: 20 years. MMSE: 25.0. MoCA: 23.0. Logical Memory: 0.0. APOEε4 alleles: 1.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "**Reasoning:** The hippocampal volume is severely reduced (Z-score -3.19, 0.1th percentile), indicating significant neurodegeneration. Despite relatively preserved cognitive scores (MMSE 25, MoCA 23), the profound atrophy suggests underlying pathology consistent with Alzheimer’s disease.  \n**Diagnosis:** Dementia (likely Alzheimer’s disease)  \n**Confidence:** High",
