  "gpt_diagnosis": "Reasoning: The hippocampal volume is mildly enlarged (12.3% above mean, Z-score 1.13), which is atypical for Alzheimer's but not necessarily pathological. Cognitive testing shows borderline MoCA (21/30) but normal MMSE (27/30), suggesting possible mild cognitive impairment (MCI) rather than dementia. The absence of APOE4 reduces Alzheimer's risk but doesn't rule out other causes.  \nDiagnosis: **MCI**  \nConfidence: **Medium** (due to conflicting hippocampal volume and cognitive scores)",
