With a Z-score of -0.52 (30.3th percentile), this represents normal volume ; whole brain volume measures 858,995 mm³, 16.5% below the reference mean. With a Z-score of -2.17 (1.5th percentile), this represents significant atrophy. ",

  "gpt_diagnosis": "Reasoning: The whole brain volume shows significant atrophy (Z-score -2.17, 1.5th percentile), which is concerning for neurodegeneration, but cognitive scores (MMSE 30, MoCA 25) are largely intact, with only mild impairment on MoCA. The absence of APOE4 reduces genetic risk but does not rule out sporadic Alzheimer's or other dementias.  \nDiagnosis: **MCI** (mild cognitive impairment)  \nConfidence: **Medium** (due to conflicting imaging and cognitive data in an older adult)",
