  "gpt_diagnosis": "Reasoning: The hippocampal volume is mildly enlarged (15.1% above mean, Z-score 1.47), which is atypical for Alzheimer's but not diagnostic. MMSE is normal (27/30), but MoCA (20/30) suggests mild cognitive impairment. Biomarkers (normal tau, reduced AV45) do not strongly support Alzheimer's pathology.  \nDiagnosis: MCI  \nConfidence: Medium",
