  "img_finding": "Image findings: hippocampal volume measures 3,827 mm³, 45.1% below the reference mean. With a Z-score of -3.90 (0.0th percentile), this represents profound atrophy. ",
  "text_data": "Age is 82.9 years. Gender is Male. Education: 16 years. MMSE: 28.0. MoCA: 19.0. Logical Memory: 0.0. APOEε4 alleles: 1.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The hippocampal volume shows profound atrophy (Z-score -3.90, 0.0th percentile), which is strongly indicative of neurodegeneration. Despite the high MMSE score (28.0), the MoCA score (19.0) suggests cognitive impairment, and the presence of an APOE4 allele increases Alzheimer's risk.  \nDiagnosis: **MCI** (likely prodromal Alzheimer's given hippocampal atrophy and APOE4, but preserved MMSE complicates a dementia diagnosis).  \nConfidence: **Medium** (high confidence in neurodegeneration, but clinical-cognitive discrepancy lowers certainty on staging).",
