  "img_finding": "Image findings: hippocampal volume measures 4,107 mm³, 41.6% below the reference mean. With a Z-score of -22.99 (0.0th percentile), this represents profound atrophy. ",
  "text_data": "Age is 91.3 years. Gender is Female. Education: 12 years. MMSE: 26.0. MoCA: 22.0. Logical Memory: 2.0. APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The hippocampal volume shows profound atrophy (41.6% below mean, Z-score -22.99), which is strongly indicative of neurodegeneration. Despite relatively preserved cognitive scores (MMSE 26, MoCA 22), the severe hippocampal atrophy suggests underlying pathology.  \n\nDiagnosis: **Dementia** (likely Alzheimer’s given hippocampal atrophy, though APOE4-negative)  \nConfidence: **High** (due to extreme hippocampal atrophy despite borderline-normal cognitive scores)",
