With a Z-score of -0.02 (49.3th percentile), this represents normal volume ; whole brain volume measures 953,359 mm³, 7.4% below the reference mean.

  "gpt_diagnosis": "Reasoning: The ventricular volume is within normal limits, but the whole brain volume is slightly reduced (7.4% below reference mean, Z-score -0.97). The MMSE score of 26 is borderline for mild cognitive impairment (MCI) in an 86-year-old male, and the presence of one APOE4 allele increases Alzheimer's risk.  \nDiagnosis: MCI  \nConfidence: Medium",
