  "gpt_diagnosis": "Reasoning: The hippocampal volume shows mild atrophy (10.5% below reference mean, Z-score -1.17), but cognitive scores are mixed (MMSE 29.0 is normal, MoCA 23.0 suggests mild impairment). APOE4 carrier status increases Alzheimer's risk, but clinical presentation is not yet severe.  \nDiagnosis: **MCI (Mild Cognitive Impairment)**  \nConfidence: **Medium** (due to conflicting MMSE/MoCA scores and early-stage hippocampal atrophy)",
