  "gpt_diagnosis": "Reasoning: The hippocampal volume shows mild atrophy (Z-score -1.36, 8.7th percentile), which is concerning but not severe. Cognitive scores (MMSE 26, MoCA 23) are slightly below normal but not in the dementia range, suggesting possible early cognitive decline. The absence of APOE4 reduces genetic risk but does not rule out neurodegeneration.  \nDiagnosis: **MCI**  \nConfidence: **Medium**",
