  "gpt_diagnosis": "**Reasoning:** The brain volume shows moderate atrophy (Z-score -1.85, 3.2th percentile), which is concerning for neurodegeneration. However, cognitive scores (MMSE 30, MoCA 25) are within normal or mildly impaired ranges, and the absence of APOE4 reduces genetic risk.  \n**Diagnosis:** Mild Cognitive Impairment (MCI)  \n**Confidence:** Medium (due to conflicting imaging and cognitive findings)",
