With a Z-score of -0.38 (35.2th percentile), this represents normal volume ; whole brain volume measures 1,002,600 mm³, 2.6% below the reference mean.

  "gpt_diagnosis": "Reasoning: The brain volumes (ventricular and whole brain) are within normal ranges, and the MMSE score of 29 is well within the normal cognitive range (≥26). The absence of APOE4 alleles further reduces Alzheimer's risk.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
