  "gpt_diagnosis": "Reasoning: The hippocampal volume shows mild atrophy (Z-score -1.37, 8.5th percentile), but cognitive screening is mixed (MMSE 30.0 normal, MoCA 24.0 borderline). No APOE4 risk allele.  \nDiagnosis: **MCI** (mild cognitive impairment)  \nConfidence: **Medium** (structural atrophy suggests early decline, but cognitive scores are not strongly impaired)",
