  "text_data": "Age is 91.8 years. Gender is Female. Education: 13 years. MMSE: 27.0. MoCA: 22.0. Logical Memory: 6.0. APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The hippocampal volume shows profound atrophy (19% below reference mean, Z-score -10.50), which is strongly suggestive of neurodegeneration. However, cognitive scores (MMSE 27, MoCA 22) are only mildly impaired, indicating preserved function despite structural decline.  \nDiagnosis: **MCI** (structural changes outweigh cognitive deficits, but not severe enough for dementia)  \nConfidence: **Medium** (discrepancy between imaging and cognitive scores warrants caution; age and APOE4 status do not strongly support AD)",
