With a Z-score of -1.32 (9.4th percentile), this represents mild atrophy; whole brain volume measures 898,136 mm³, 3.2% below the reference mean. With a Z-score of -0.39 (34.9th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The ventricular volume shows mild atrophy (Z-score -1.32), while whole brain volume is within normal range (Z-score -0.39). The MMSE score of 22 suggests mild cognitive impairment, and the absence of APOE4 reduces Alzheimer's genetic risk but does not rule it out given age-related changes.  \nDiagnosis: MCI  \nConfidence: Medium",
