  "img_finding": "Image findings: hippocampal volume measures 5,941 mm³, 14.7% below the reference mean. With a Z-score of -1.27 (10.1th percentile), this represents mild atrophy; whole brain volume measures 1,067,650 mm³, 3.7% above the reference mean. With a Z-score of 0.49 (68.8th percentile), this represents normal volume . ",
  "text_data": "Age is 82.6 years. Gender is Male. Education: 20 years. MMSE: 24.0. MoCA: 24.0. Logical Memory: 0.0. APOEε4 alleles: 1.0. ",
  "true_diagnosis": "Diagnosis: AD.",
  "gpt_diagnosis": "Reasoning: The patient shows mild hippocampal atrophy (Z-score -1.27) but normal whole brain volume, with cognitive scores (MMSE 24, MoCA 24) slightly below typical cutoffs for normal cognition (often ≤25 for MMSE, ≤26 for MoCA). APOE4 positivity increases Alzheimer's risk, but scores are borderline.  \nDiagnosis: **MCI** (mild cognitive impairment)  \nConfidence: **Medium** (cognitive scores are near-normal, but hippocampal atrophy and APOE4 suggest early decline).",
