  "gpt_diagnosis": "Reasoning: The hippocampal volume shows profound atrophy (Z-score -3.62, 0.0th percentile), which is strongly associated with Alzheimer's pathology. Despite relatively preserved cognitive scores (MMSE 26, MoCA 24), the degree of atrophy suggests neurodegeneration is likely outpacing clinical symptoms.  \nDiagnosis: **MCI (likely prodromal Alzheimer's disease)**  \nConfidence: **High**",
