With a Z-score of -0.58 (28.0th percentile), this represents normal volume ; whole brain volume measures 738,653 mm³, 20.4% below the reference mean. With a Z-score of -2.45 (0.7th percentile), this represents significant atrophy. ",

  "gpt_diagnosis": "Reasoning: The patient shows significant whole brain atrophy (Z-score -2.45, 0.7th percentile) but normal ventricular volume. The MMSE score of 23 is borderline, suggesting possible cognitive impairment, though APOE4 negative status reduces genetic risk.  \nDiagnosis: MCI  \nConfidence: Medium",
