With a Z-score of 0.94 (82.6th percentile), this represents normal volume ; whole brain volume measures 917,076 mm³, 5.9% below the reference mean.

  "gpt_diagnosis": "**Reasoning:** The ventricular volume is slightly above the reference mean but still within the normal range (Z-score 0.94), while whole brain volume is slightly below the reference mean but also normal (Z-score -0.74). The MMSE score of 26 is borderline but does not strongly indicate cognitive impairment.  \n\n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** Medium (due to borderline MMSE and normal imaging, but no strong evidence of impairment)",
