With a Z-score of -0.94 (17.3th percentile), this represents normal volume ; whole brain volume measures 917,006 mm³, 10.9% below the reference mean. With a Z-score of -1.43 (7.7th percentile), this represents mild atrophy. ",

  "gpt_diagnosis": "Reasoning: The patient shows mild whole brain atrophy (Z-score -1.43, 7.7th percentile) but normal ventricular volume. The MMSE score of 23 suggests mild cognitive impairment, and the absence of APOE4 reduces genetic risk.  \nDiagnosis: MCI  \nConfidence: Medium",
