  "text_data": "Age is 66.3 years. Gender is Male. Education: 13 years. MMSE: 29.0. MoCA: 25.0. Logical Memory: 10.0. APOEε4 alleles: 1.0. ",
  "true_diagnosis": "Diagnosis: CN.",
  "gpt_diagnosis": "Reasoning: The hippocampal volume is within the normal range (Z-score 0.20, 57.8th percentile), and cognitive scores (MMSE 29, MoCA 25) are borderline normal (MoCA slightly below typical cutoff of 26 but not strongly indicative of impairment). No significant structural or cognitive decline is evident.  \nDiagnosis: **CN (Cognitively Normal)**  \nConfidence: **Medium** (MoCA is slightly reduced but not strongly suggestive of impairment; APOE4 carrier status increases future risk but does not affect current diagnosis).",
