With a Z-score of -1.08 (14.1th percentile), this represents mild atrophy; whole brain volume measures 939,644 mm³, 8.7% below the reference mean. With a Z-score of -1.14 (12.7th percentile), this represents mild atrophy. ",

  "gpt_diagnosis": "Reasoning: The patient shows mild atrophy in both ventricular and whole brain volumes, with Z-scores indicating values below the reference mean. The MMSE score of 23.0 suggests mild cognitive impairment, and the absence of APOE4 reduces genetic risk but does not rule out neurodegeneration.  \nDiagnosis: MCI  \nConfidence: Medium",
