With a Z-score of -0.64 (26.1th percentile), this represents normal volume ; whole brain volume measures 1,045,990 mm³, 3.1% below the reference mean. With a Z-score of -0.40 (34.4th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The brain volumes (ventricular and whole brain) are within normal ranges, but the cognitive scores (MMSE: 24, MoCA: 18) suggest mild cognitive impairment, particularly given the MoCA score below the typical cutoff of 26. The presence of two APOE4 alleles increases the risk for Alzheimer's pathology.  \nDiagnosis: MCI  \nConfidence: Medium",
