With a Z-score of -0.25 (40.1th percentile), this represents normal volume ; whole brain volume measures 1,158,490 mm³, 7.3% above the reference mean. With a Z-score of 0.95 (82.9th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The ventricular and whole brain volumes are within normal ranges, and the MMSE score of 26 is borderline but still within the normal range for cognitive function. The presence of one APOE4 allele increases Alzheimer's risk but does not confirm impairment.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium",
