  "gpt_diagnosis": "Reasoning: The hippocampal volume is significantly reduced (Z-score -2.06, 2.0th percentile), which is strongly associated with Alzheimer's pathology. The MMSE (25) and MoCA (22) scores indicate mild cognitive impairment, and the presence of one APOE4 allele increases Alzheimer's risk.  \nDiagnosis: MCI (likely due to Alzheimer's disease)  \nConfidence: Medium (clinical correlation and biomarker support needed for definitive diagnosis)",
