  "gpt_diagnosis": "Reasoning: The hippocampal volume shows significant atrophy (Z-score -2.90, 0.2th percentile), which is strongly associated with Alzheimer's pathology. However, cognitive scores (MMSE 30, MoCA 25) are within normal to mildly impaired ranges, and amyloid PET (AV45) is normal, suggesting no current dementia.  \nDiagnosis: MCI  \nConfidence: Medium",
