With a Z-score of 1.10 (86.5th percentile), this represents mild enlargement; whole brain volume measures 900,661 mm³, 3.0% below the reference mean. With a Z-score of -0.36 (36.1th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The ventricular volume is mildly enlarged (40.9% above reference mean), which can indicate atrophy, but whole brain volume is within normal limits (3.0% below reference mean). The MMSE score of 24 is borderline, suggesting possible cognitive impairment, but no APOE4 risk allele is present.  \nDiagnosis: MCI  \nConfidence: Medium",
