  "gpt_diagnosis": "Reasoning: The hippocampal volume is slightly below the reference mean but still within the normal range (Z-score -0.67). Cognitive scores (MMSE 29, MoCA 26) are strong, and there is no significant amyloid burden (AV45: mild reduced). APOE4 negative status further reduces Alzheimer's risk.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
