With a Z-score of -1.19 (11.6th percentile), this represents mild atrophy; whole brain volume measures 972,228 mm³, 5.5% below the reference mean. With a Z-score of -0.72 (23.4th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The ventricular volume shows mild atrophy, but whole brain volume is within normal limits. The MMSE score of 22 suggests mild cognitive impairment, and the absence of APOE4 reduces genetic risk but does not rule out neurodegeneration.  \nDiagnosis: MCI  \nConfidence: Medium",
