  "true_diagnosis": "Diagnosis: CN.",
  "gpt_diagnosis": "Reasoning: The hippocampal volume is mildly enlarged (14.8% above mean, Z-score 1.35), which is atypical for Alzheimer's but not necessarily pathological. Cognitive scores (MMSE 30, MoCA 25) are within normal limits, though MoCA is borderline. APOE4 carrier status increases risk but does not confirm disease.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to atypical hippocampal enlargement and borderline MoCA)",
