  "gpt_diagnosis": "Reasoning: The hippocampal volume shows profound atrophy (45.1% below reference mean, Z-score -24.91), which is strongly indicative of neurodegeneration. However, cognitive scores (MMSE 29, MoCA 23) are relatively preserved, suggesting possible early-stage impairment or resilience despite structural decline.  \nDiagnosis: **MCI** (given the structural severity but only mild cognitive deficits)  \nConfidence: **Medium** (discrepancy between imaging and cognitive scores warrants caution)",
