With a Z-score of 0.76 (77.5th percentile), this represents normal volume ; whole brain volume measures 865,250 mm³, 19.8% below the reference mean. With a Z-score of -2.58 (0.5th percentile), this represents significant atrophy. ",

  "gpt_diagnosis": "Reasoning: The patient shows significant whole brain atrophy (Z-score -2.58, 0.5th percentile) despite normal ventricular volume and a high MMSE score (29/30). The absence of APOE4 and preserved cognitive function suggest early or compensated neurodegeneration rather than full dementia.  \nDiagnosis: MCI  \nConfidence: Medium",
