With a Z-score of -0.12 (45.3th percentile), this represents normal volume ; whole brain volume measures 877,103 mm³, 5.5% below the reference mean.

  "gpt_diagnosis": "Reasoning: The brain volumes (ventricular and whole brain) are within normal ranges, though slightly below the reference mean. The MMSE score of 23 suggests mild cognitive impairment, but the absence of APOE4 reduces genetic risk for Alzheimer's.  \nDiagnosis: MCI  \nConfidence: Medium",
