With a Z-score of -0.15 (43.9th percentile), this represents normal volume ; whole brain volume measures 959,543 mm³, 6.8% below the reference mean. With a Z-score of -0.89 (18.8th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The ventricular and whole brain volumes are within normal ranges, albeit slightly below the reference mean. The MMSE score of 30 is optimal, but the MoCA score of 25 suggests mild cognitive impairment (MCI), though not severe enough for dementia. The absence of APOE4 reduces genetic risk.  \nDiagnosis: MCI  \nConfidence: Medium",
